       DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation.


       See DBIx::Class::Schema::Loader.


       This is the base class for the storage-specific "DBIx::Class::Schema::*" classes, and
       implements the common functionality between them.


       These constructor options are the base options for "loader_options" in
       DBIx::Class::Schema::Loader.  Available constructor options are:

       Skip setting up relationships.  The default is to attempt the loading of relationships.

       Skip loading of other classes in @INC. The default is to merge all other classes with the
       same name found in @INC into the schema file we are creating.

       Static schemas (ones dumped to disk) will, by default, use the new-style relationship
       names and singularized Results, unless you're overwriting an existing dump made by an
       older version of DBIx::Class::Schema::Loader, in which case the backward compatible
       RelBuilder will be activated, and the appropriate monikerization used.


           naming => 'current'

       will disable the backward-compatible RelBuilder and use the new-style relationship names
       along with singularized Results, even when overwriting a dump made with an earlier

       The option also takes a hashref:

           naming => {
               relationships    => 'v8',
               monikers         => 'v8',
               column_accessors => 'v8',
               force_ascii      => 1,


           naming => { ALL => 'v8', force_ascii => 1 }

       The keys are:

       ALL Set "relationships", "monikers" and "column_accessors" to the specified value.

           How to name relationship accessors.

           How to name Result classes.

           How to name column accessors in Result classes.

           For "v8" mode and later, uses String::ToIdentifier::EN instead of
           String::ToIdentifier::EN::Unicode to force monikers and other identifiers to ASCII.

       The values can be:

           Latest style, whatever that happens to be.

       v4  Unsingularlized monikers, "has_many" only relationships with no _id stripping.

       v5  Monikers singularized as whole words, "might_have" relationships for FKs on "UNIQUE"
           constraints, "_id" stripping for belongs_to relationships.

           Some of the "_id" stripping edge cases in 0.05003 have been reverted for the v5

       v6  All monikers and relationships are inflected using Lingua::EN::Inflect::Phrase, and
           there is more aggressive "_id" stripping from relationship names.

           In general, there is very little difference between v5 and v6 schemas.

       v7  This mode is identical to "v6" mode, except that monikerization of CamelCase table
           names is also done better (but best in v8.)

           CamelCase column names in case-preserving mode will also be handled better for
           relationship name inflection (but best in v8.) See "preserve_case".

           In this mode, CamelCase "column_accessors" are normalized based on case transition
           instead of just being lowercased, so "FooId" becomes "foo_id".

       v8  (EXPERIMENTAL)

           The default mode is "v7", to get "v8" mode, you have to specify it in "naming"
           explicitly until 0.08 comes out.

           "monikers" and "column_accessors" are created using String::ToIdentifier::EN::Unicode
           or String::ToIdentifier::EN if "force_ascii" is set; this is only significant for
           names with non-"\w" characters such as ".".

           CamelCase identifiers with words in all caps, e.g. "VLANValidID" are supported
           correctly in this mode.

           For relationships, belongs_to accessors are made from column names by stripping
           postfixes other than "_id" as well, for example just "Id", "_?ref", "_?cd", "_?code"
           and "_?num", case insensitively.

           For "monikers", this option does not inflect the table names but makes monikers based
           on the actual name. For "column_accessors" this option does not normalize CamelCase
           column names to lowercase column accessors, but makes accessors that are the same
           names as the columns (with any non-\w chars replaced with underscores.)

           For "monikers", singularizes the names using the most current inflector. This is the
           same as setting the option to "current".

           For "monikers", pluralizes the names, using the most current inflector.

       Dynamic schemas will always default to the 0.04XXX relationship names and won't
       singularize Results for backward compatibility, to activate the new RelBuilder and
       singularization put this in your "" file:


       Or if you prefer to use 0.07XXX features but insure that nothing breaks in the next major
       version upgrade:


       If true, will not print the usual "Dumping manual schema ... Schema dump completed."
       messages. Does not affect warnings (except for warnings related to

       If true, don't actually write out the generated files.  This can only be used with static
       schema generation.

       By default POD will be generated for columns and relationships, using database metadata
       for the text if available and supported.

       Comment metadata can be stored in two ways.

       The first is that you can create two tables named "table_comments" and "column_comments"
       respectively. These tables must exist in the same database and schema as the tables they
       describe. They both need to have columns named "table_name" and "comment_text". The second
       one needs to have a column named "column_name". Then data stored in these tables will be
       used as a source of metadata about tables and comments.

       (If you wish you can change the name of these tables with the parameters
       "table_comments_table" and "column_comments_table".)

       As a fallback you can use built-in commenting mechanisms.  Currently this is only
       supported for PostgreSQL, Oracle and MySQL.  To create comments in PostgreSQL you add
       statements of the form "COMMENT ON TABLE some_table IS '...'", the same syntax is used in
       Oracle. To create comments in MySQL you add "COMMENT '...'" to the end of the column or
       table definition.  Note that MySQL restricts the length of comments, and also does not
       handle complex Unicode characters properly.

       Set this to 0 to turn off all POD generation.

       Controls where table comments appear in the generated POD. Smaller table comments are
       appended to the "NAME" section of the documentation, and larger ones are inserted into
       "DESCRIPTION" instead. You can force a "DESCRIPTION" section to be generated with the
       comment always, only use "NAME", or choose the length threshold at which the comment is
       forced into the description.

           Use "NAME" section only.

           Force "DESCRIPTION" always.

           Use "DESCRIPTION" if length > "pod_comment_spillover_length", this is the default.

       When pod_comment_mode is set to "auto", this is the length of the comment at which it will
       be forced into a separate description section.

       The default is 60

       The table to look for comments about tables in.  By default "table_comments".  See
       "generate_pod" for details.

       This must not be a fully qualified name, the table will be looked for in the same database
       and schema as the table whose comment is being retrieved.

       The table to look for comments about columns in.  By default "column_comments".  See
       "generate_pod" for details.

       This must not be a fully qualified name, the table will be looked for in the same database
       and schema as the table/column whose comment is being retrieved.

       Hashref of attributes to pass to each generated relationship, listed by type.  Also
       supports relationship type 'all', containing options to pass to all generated
       relationships.  Attributes set for more specific relationship types override those set in
       'all', and any attributes specified by this option override the introspected attributes of
       the foreign key if any.

       For example:

           relationship_attrs => {
               has_many   => { cascade_delete => 1, cascade_copy => 1 },
               might_have => { cascade_delete => 1, cascade_copy => 1 },

       use this to turn DBIx::Class cascades to on on your has_many and might_have relationships,
       they default to off.

       Can also be a coderef, for more precise control, in which case the coderef gets this hash
       of parameters (as a list):

           rel_name        # the name of the relationship
           rel_type        # the type of the relationship: 'belongs_to', 'has_many' or 'might_have'
           local_source    # the DBIx::Class::ResultSource object for the source the rel is *from*
           remote_source   # the DBIx::Class::ResultSource object for the source the rel is *to*
           local_table     # the DBIx::Class::Schema::Loader::Table object for the table of the source the rel is from
           local_cols      # an arrayref of column names of columns used in the rel in the source it is from
           remote_table    # the DBIx::Class::Schema::Loader::Table object for the table of the source the rel is to
           remote_cols     # an arrayref of column names of columns used in the rel in the source it is to
           attrs           # the attributes that would be set

       it should return the new hashref of attributes, or nothing for no changes.

       For example:

           relationship_attrs => sub {
               my %p = @_;

               say "the relationship name is: $p{rel_name}";
               say "the relationship is a: $p{rel_type}";
               say "the local class is: ",  $p{local_source}->result_class;
               say "the remote class is: ", $p{remote_source}->result_class;
               say "the local table is: ", $p{local_table}->sql_name;
               say "the rel columns in the local table are: ", (join ", ", @{$p{local_cols}});
               say "the remote table is: ", $p{remote_table}->sql_name;
               say "the rel columns in the remote table are: ", (join ", ", @{$p{remote_cols}});

               if ($p{local_table} eq 'dogs' && @{$p{local_cols}} == 1 && $p{local_cols}[0] eq 'name') {
                   $p{attrs}{could_be_snoopy} = 1;

                   reutrn $p{attrs};

       These are the default attributes:

           has_many => {
               cascade_delete => 0,
               cascade_copy   => 0,
           might_have => {
               cascade_delete => 0,
               cascade_copy   => 0,
           belongs_to => {
               on_delete => 'CASCADE',
               on_update => 'CASCADE',
               is_deferrable => 1,

       For belongs_to relationships, these defaults are overridden by the attributes introspected
       from the foreign key in the database, if this information is available (and the driver is
       capable of retrieving it.)

       This information overrides the defaults mentioned above, and is then itself overridden by
       the user's "relationship_attrs" for "belongs_to" if any are specified.

       In general, for most databases, for a plain foreign key with no rules, the values for a
       belongs_to relationship will be:

           on_delete     => 'NO ACTION',
           on_update     => 'NO ACTION',
           is_deferrable => 0,

       In the cases where an attribute is not supported by the DB, a value matching the actual
       behavior is used, for example Oracle does not support "ON UPDATE" rules, so "on_update" is
       set to "NO ACTION". This is done so that the behavior of the schema is preserved when
       cross deploying to a different RDBMS such as SQLite for testing.

       In the cases where the DB does not support "DEFERRABLE" foreign keys, the value is set to
       1 if DBIx::Class has a working "$storage->with_deferred_fk_checks". This is done so that
       the same DBIx::Class code can be used, and cross deployed from and to such databases.

       If set to true, each constructive DBIx::Class statement the loader decides to execute will
       be "warn"-ed before execution.

       Set the name of the schema to load (schema in the sense that your database vendor means

       Can be set to an arrayref of schema names for multiple schemas, or the special value "%"
       for all schemas.

       For MSSQL, Sybase ASE, and Informix can be set to a hashref of databases as keys and
       arrays of owners as values, set to the value:

           { '%' => '%' }

       for all owners in all databases.

       Name clashes resulting from the same table name in different databases/schemas will be
       resolved automatically by prefixing the moniker with the database and/or schema.

       To prefix/suffix all monikers with the database and/or schema, see "moniker_parts".

       The database table names are represented by the DBIx::Class::Schema::Loader::Table class
       in the loader, the DBIx::Class::Schema::Loader::Table::Sybase class for Sybase ASE and
       DBIx::Class::Schema::Loader::Table::Informix for Informix.

       Monikers are created normally based on just the name property, corresponding to the table
       name, but can consist of other parts of the fully qualified name of the table.

       The "moniker_parts" option is an arrayref of methods on the table class corresponding to
       parts of the fully qualified table name, defaulting to "['name']", in the order those
       parts are used to create the moniker name.  The parts are joined together using

       The 'name' entry must be present.

       Below is a table of supported databases and possible "moniker_parts".

       ·   DB2, Firebird, mysql, Oracle, Pg, SQLAnywhere, SQLite, MS Access

           "schema", "name"

       ·   Informix, MSSQL, Sybase ASE

           "database", "schema", "name"

       String used to join "moniker_parts" when creating the moniker.  Defaults to the empty
       string. Use "::" to get a separate namespace per database and/or schema.

       Only load matching tables.

       These can be specified either as a regex (preferably on the "qr//" form), or as an
       arrayref of arrayrefs.  Regexes are matched against the (unqualified) table name, while
       arrayrefs are matched according to "moniker_parts".

       For example:

           db_schema => [qw(some_schema other_schema)],
           moniker_parts => [qw(schema name)],
           constraint => [
               [ qr/\Asome_schema\z/ => qr/\A(?:foo|bar)\z/ ],
               [ qr/\Aother_schema\z/ => qr/\Abaz\z/ ],

       In this case only the tables "foo" and "bar" in "some_schema" and "baz" in "other_schema"
       will be dumped.

       Exclude matching tables.

       The tables to exclude are specified in the same way as for the "constraint" option.

       Overrides the default table name to moniker translation. Either

       ·   a nested hashref, which will be traversed according to "moniker_parts"

           For example:

               moniker_parts => [qw(schema name)],
               moniker_map => {
                   foo => {
                       bar  => "FooishBar",

           In which case the table "bar" in the "foo" schema would get the moniker "FooishBar".

       ·   a hashref of unqualified table name keys and moniker values

       ·   a coderef that returns the moniker, which is called with the following arguments:

           ·   the DBIx::Class::Schema::Loader::Table object for the table

           ·   the default moniker that DBIC would ordinarily give this table

           ·   a coderef that can be called with either of the hashref forms to get the moniker
               mapped accordingly.  This is useful if you need to handle some monikers specially,
               but want to use the hashref form for the rest.

       If the hash entry does not exist, or the function returns a false value, the code falls
       back to default behavior for that table name.

       The default behavior is to split on case transition and non-alphanumeric boundaries,
       singularize the resulting phrase, then join the titlecased words together. Examples:

           Table Name       | Moniker Name
           luser            | Luser
           luser_group      | LuserGroup
           luser-opts       | LuserOpt
           stations_visited | StationVisited
           routeChange      | RouteChange

       Map for overriding the monikerization of individual "moniker_parts".  The keys are the
       moniker part to override, the value is either a hashref or coderef for mapping the
       corresponding part of the moniker. If a coderef is used, it gets called with the moniker
       part and the hash key the code ref was found under.

       For example:

           moniker_part_map => {
               schema => sub { ... },

       Given the table "", the code ref would be called with the arguments "foo" and
       "schema", plus a coderef similar to the one described in "moniker_map".

       "moniker_map" takes precedence over this.

       Same as moniker_map, but for column accessor names.  The nested hashref form is traversed
       according to "moniker_parts", with an extra level at the bottom for the column name.  If a
       coderef is passed, the code is called with the following arguments:

       ·   the DBIx::Class::Schema::Loader::Column object for the column

       ·   the default accessor name that DBICSL would ordinarily give this column

       ·   a hashref of this form:

                   table_class     => name of the DBIC class we are building,
                   table_moniker   => calculated moniker for this table (after moniker_map if present),
                   table           => the DBIx::Class::Schema::Loader::Table object for the table,
                   full_table_name => schema-qualified name of the database table (RDBMS specific),
                   schema_class    => name of the schema class we are building,
                   column_info     => hashref of column info (data_type, is_nullable, etc),

       ·   a coderef that can be called with a hashref map

       Similar in idea to moniker_map, but different in the details.  It can be a hashref or a
       code ref.

       If it is a hashref, keys can be either the default relationship name, or the moniker. The
       keys that are the default relationship name should map to the name you want to change the
       relationship to. Keys that are monikers should map to hashes mapping relationship names to
       their translation.  You can do both at once, and the more specific moniker version will be
       picked up first.  So, for instance, you could have

               bar => "baz",
               Foo => {
                   bar => "blat",

       and relationships that would have been named "bar" will now be named "baz" except that in
       the table whose moniker is "Foo" it will be named "blat".

       If it is a coderef, it will be passed a hashref of this form:

               name           => default relationship name,
               type           => the relationship type eg: C<has_many>,
               local_class    => name of the DBIC class we are building,
               local_moniker  => moniker of the DBIC class we are building,
               local_columns  => columns in this table in the relationship,
               remote_class   => name of the DBIC class we are related to,
               remote_moniker => moniker of the DBIC class we are related to,
               remote_columns => columns in the other table in the relationship,
               # for type => "many_to_many" only:
               link_class     => name of the DBIC class for the link table,
               link_moniker   => moniker of the DBIC class for the link table,
               link_rel_name  => name of the relationship to the link table,

       In addition it is passed a coderef that can be called with a hashref map.

       DBICSL will try to use the value returned as the relationship name.

       Just like "moniker_map" above (can be hash/code-ref, falls back to default if hash key
       does not exist or coderef returns false), but acts as a map for pluralizing relationship
       names.  The default behavior is to utilize "to_PL" in Lingua::EN::Inflect::Phrase.

       As "inflect_plural" above, but for singularizing relationship names.  Default behavior is
       to utilize "to_S" in Lingua::EN::Inflect::Phrase.

       Base class for your schema classes. Defaults to 'DBIx::Class::Schema'.

       List of components to load into the Schema class.

       Base class for your table classes (aka result classes). Defaults to 'DBIx::Class::Core'.

       List of additional base classes all of your table classes will use.

       List of additional base classes all of your table classes will use that need to be

       List of additional classes which all of your table classes will use.

       List of additional components to be loaded into all of your Result classes.  A good
       example would be InflateColumn::DateTime

       A hashref of moniker keys and component values.  Unlike "components", which loads the
       given components into every Result class, this option allows you to load certain
       components for specified Result classes. For example:

           result_components_map => {
               StationVisited => '+YourApp::Schema::Component::StationVisited',
               RouteChange    => [

       You may use this in conjunction with "components".

       List of Moose roles to be applied to all of your Result classes.

       A hashref of moniker keys and role values.  Unlike "result_roles", which applies the given
       roles to every Result class, this option allows you to apply certain roles for specified
       Result classes. For example:

           result_roles_map => {
               StationVisited => [
               RouteChange    => 'YourApp::Role::TripEvent',

       You may use this in conjunction with "result_roles".

       This is now the default, to go back to "load_classes" in DBIx::Class::Schema pass a 0.

       Generate result class names suitable for "load_namespaces" in DBIx::Class::Schema and call
       that instead of "load_classes" in DBIx::Class::Schema. When using this option you can also
       specify any of the options for "load_namespaces" (i.e. "result_namespace",
       "resultset_namespace", "default_resultset_class"), and they will be added to the call (and
       the generated result class names adjusted appropriately).

       The value of this option is a perl libdir pathname.  Within that directory this module
       will create a baseline manual DBIx::Class::Schema module set, based on what it creates at

       The created schema class will have the same classname as the one on which you are setting
       this option (and the ResultSource classes will be based on this name as well).

       Normally you wouldn't hard-code this setting in your schema class, as it is meant for one-
       time manual usage.

       See "dump_to_dir" in DBIx::Class::Schema::Loader for examples of the recommended way to
       access this functionality.

       Deprecated.  See "really_erase_my_files" below, which does *not* mean the same thing as
       the old "dump_overwrite" setting from previous releases.

       Default false.  If true, Loader will unconditionally delete any existing files before
       creating the new ones from scratch when dumping a schema to disk.

       The default behavior is instead to only replace the top portion of the file, up to and
       including the final stanza which contains "# DO NOT MODIFY THE FIRST PART OF THIS FILE"
       leaving any customizations you placed after that as they were.

       When "really_erase_my_files" is not set, if the output file already exists, but the
       aforementioned final stanza is not found, or the checksum contained there does not match
       the generated contents, Loader will croak and not touch the file.

       You should really be using version control on your schema classes (and all of the rest of
       your code for that matter).  Don't blame me if a bug in this code wipes something out when
       it shouldn't have, you've been warned.

       Default false.  If false, when updating existing files, Loader will refuse to modify any
       Loader-generated code that has been modified since its last run (as determined by the
       checksum Loader put in its comment lines).

       If true, Loader will discard any manual modifications that have been made to Loader-
       generated code.

       Again, you should be using version control on your schema classes.  Be careful with this

       Omit the package version from the signature comment.

       Omit the creation timestamp from the signature comment.

       Hook for adding extra attributes to the column_info for a column.

       Must be a coderef that returns a hashref with the extra attributes.

       Receives the DBIx::Class::Schema::Loader::Table object, column name and column_info.

       For example:

           custom_column_info => sub {
               my ($table, $column_name, $column_info) = @_;

               if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') {
                   return { is_snoopy => 1 };

       This attribute can also be used to set "inflate_datetime" on a non-datetime column so it
       also receives the "datetime_timezone" and/or "datetime_locale".

       Sets the timezone attribute for DBIx::Class::InflateColumn::DateTime for all columns with
       the DATE/DATETIME/TIMESTAMP data_types.

       Sets the locale attribute for DBIx::Class::InflateColumn::DateTime for all columns with
       the DATE/DATETIME/TIMESTAMP data_types.

       Pass a 0 for this option when using MySQL if you DON'T want "datetime_undef_if_invalid =>
       1" in your column info for DATE, DATETIME and TIMESTAMP columns.

       The default is recommended to deal with data such as "00/00/00" which sometimes ends up in
       such columns in MySQL.

       File in Perl format, which should return a HASH reference, from which to read loader

       Normally database names are lowercased and split by underscore, use this option if you
       have CamelCase database names.

       Drivers for case sensitive databases like Sybase ASE or MSSQL with a case-sensitive
       collation will turn this option on unconditionally.

       NOTE: "naming" = "v8" is highly recommended with this option as the semantics of this mode
       are much improved for CamelCase database names.

       "naming" = "v7" or greater is required with this option.

       Set to true to prepend the "db_schema" to table names for "__PACKAGE__->table" calls, and
       to some other things like Oracle sequences.

       This attribute is automatically set to true for multi db_schema configurations, unless
       explicitly set to false by the user.

       Creates Schema and Result classes that use Moose, MooseX::NonMoose and
       MooseX::MarkAsMethods (or namespace::autoclean, see below). The default content after the
       md5 sum also makes the classes immutable.

       It is safe to upgrade your existing Schema to this option.

       By default, we use MooseX::MarkAsMethods to remove imported functions from your generated
       classes.  It uses namespace::autoclean to do this, after telling your object's metaclass
       that any operator overloads in your class are methods, which will cause
       namespace::autoclean to spare them from removal.

       This prevents the "Hey, where'd my overloads go?!" effect.

       If you don't care about operator overloads, enabling this option falls back to just using
       namespace::autoclean itself.

       If none of the above made any sense, or you don't have some pressing need to only use
       namespace::autoclean, leaving this set to the default is recommended.

       This option controls how accessors for column names which collide with perl methods are
       named. See "COLUMN ACCESSOR COLLISIONS" for more information.

       This option takes either a single sprintf format or a hashref of strings which are
       compiled to regular expressions that map to sprintf formats.


           col_collision_map => 'column_%s'

           col_collision_map => { '(.*)' => 'column_%s' }

           col_collision_map => { '(foo).*(bar)' => 'column_%s_%s' }

       Works just like "col_collision_map", but for relationship names/accessors rather than
       column names/accessors.

       The default is to just append "_rel" to the relationship name, see "RELATIONSHIP NAME

       Automatically promotes the largest unique constraints with non-nullable columns on tables
       to primary keys, assuming there is only one largest unique constraint.

       Generate "many_to_many" relationship bridges even if the link table has extra columns
       other than the foreign keys.  The primary key must still equal the union of the foreign

       An optional hook that lets you filter the generated text for various classes through a
       function that change it in any way that you want.  The function will receive the type of
       file, "schema" or "result", class and code; and returns the new code to use instead.  For
       instance you could add custom comments, or do anything else that you want.

       The option can also be set to a string, which is then used as a filter program, e.g.

       If this exists but fails to return text matching "/\bpackage\b/", no file will be

           filter_generated_code => sub {
               my ($type, $class, $text) = @_;
               return $new_code;

       You can also use this option to set perltidy markers in your generated classes.  This will
       leave the generated code in the default format, but will allow you to tidy your classes at
       any point in future, without worrying about changing the portions of the file which are
       checksummed, since "perltidy" will just ignore all text between the markers.

           filter_generated_code => sub {
               return "#<<<\n$_[2]\n#>>>";


       None of these methods are intended for direct invocation by regular users of
       DBIx::Class::Schema::Loader. Some are proxied via DBIx::Class::Schema::Loader.

       Constructor for DBIx::Class::Schema::Loader::Base, used internally by

       Does the actual schema-construction work.

       Arguments: schema

       Rescan the database for changes. Returns a list of the newly added table monikers.

       The schema argument should be the schema class or object to be affected.  It should
       probably be derived from the original schema_class used during "load".

       Arguments: class

       Returns the full path to the file for a class that the class has been or will be dumped
       to. This is a file in a temp dir for a dynamic schema.

       Returns a sorted list of loaded tables, using the original database table names.

       Returns a hashref of loaded table to moniker mappings.  There will be two entries for each
       table, the original name and the "normalized" name, in the case that the two are different
       (such as databases that like uppercase table names, or preserve your original mixed-case
       definitions, or what-have-you).

       Returns a hashref of table to class mappings.  In some cases it will contain multiple
       entries per table for the original and normalized table names, as above in "monikers".

       Returns an arrayref of classes that were actually generated (i.e. not skipped because
       there were no changes).


       If you use the loader on a database with table and column names in a language other than
       English, you will want to turn off the English language specific heuristics.

       To do so, use something like this in your loader options:

           naming           => { monikers => 'v4' },
           inflect_singular => sub { "$_[0]_rel" },
           inflect_plural   => sub { "$_[0]_rel" },


       Occasionally you may have a column name that collides with a perl method, such as "can".
       In such cases, the default action is to set the "accessor" of the column spec to "undef".

       You can then name the accessor yourself by placing code such as the following below the

           __PACKAGE__->add_column('+can' => { accessor => 'my_can' });

       Another option is to use the "col_collision_map" option.


       In very rare cases, you may get a collision between a generated relationship name and a
       method in your Result class, for example if you have a foreign key called "belongs_to".

       This is a problem because relationship names are also relationship accessor methods in

       The default behavior is to append "_rel" to the relationship name and print out a warning
       that refers to this text.

       You can also control the renaming with the "rel_collision_map" option.
