NAME
DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation.
SYNOPSIS
See DBIx::Class::Schema::Loader.
DESCRIPTION
This is the base class for the storage-specific "DBIx::Class::Schema::*" classes, and
implements the common functionality between them.
CONSTRUCTOR OPTIONS
These constructor options are the base options for "loader_options" in
DBIx::Class::Schema::Loader. Available constructor options are:
skip_relationships
Skip setting up relationships. The default is to attempt the loading of relationships.
skip_load_external
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.
naming
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.
Specifying
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
version.
The option also takes a hashref:
naming => {
relationships => 'v8',
monikers => 'v8',
column_accessors => 'v8',
force_ascii => 1,
}
or
naming => { ALL => 'v8', force_ascii => 1 }
The keys are:
ALL Set "relationships", "monikers" and "column_accessors" to the specified value.
relationships
How to name relationship accessors.
monikers
How to name Result classes.
column_accessors
How to name column accessors in Result classes.
force_ascii
For "v8" mode and later, uses String::ToIdentifier::EN instead of
String::ToIdentifier::EM::Unicode to force monikers and other identifiers to ASCII.
The values can be:
current
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
RelBuilder.
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.
preserve
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.)
singular
For "monikers", singularizes the names using the most current inflector. This is the
same as setting the option to "current".
plural
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 "Schema.pm" file:
__PACKAGE__->naming('current');
Or if you prefer to use 0.07XXX features but insure that nothing breaks in the next major
version upgrade:
__PACKAGE__->naming('v7');
quiet
If true, will not print the usual "Dumping manual schema ... Schema dump completed."
messages. Does not affect warnings (except for warnings related to
"really_erase_my_files".)
dry_run
If true, don't actually write out the generated files. This can only be used with static
schema generation.
generate_pod
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.
pod_comment_mode
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.
name
Use "NAME" section only.
description
Force "DESCRIPTION" always.
auto
Use "DESCRIPTION" if length > "pod_comment_spillover_length", this is the default.
pod_comment_spillover_length
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
table_comments_table
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.
column_comments_table
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.
relationship_attrs
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 # a 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 # a 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.
debug
If set to true, each constructive DBIx::Class statement the loader decides to execute will
be "warn"-ed before execution.
db_schema
Set the name of the schema to load (schema in the sense that your database vendor means
it).
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".
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
"moniker_part_separator".
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"
moniker_part_separator
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.
constraint
Only load matching tables.
exclude
Exclude matching tables.
These can be specified either as a regex (preferrably 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.
moniker_map
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 for a translator function taking a table object argument (which stringifies
to the unqualified table name) and returning a scalar moniker
The function is also passed 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
moniker_part_map
Map for overriding the monikerization of individual "moniker_parts". The keys are the
moniker part to override, the value is either a hashref of 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 "foo.bar", 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.
col_accessor_map
Same as moniker_map, but for column accessor names. If a coderef is passed, the code is
called with arguments of
the name of the column in the underlying database,
default accessor name that DBICSL would ordinarily give this column,
{
table_class => name of the DBIC class we are building,
table_moniker => calculated moniker for this table (after moniker_map if present),
table => table object of interface DBIx::Class::Schema::Loader::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),
}
coderef ref that can be called with a hashref map
the table object stringifies to the unqualified table name.
rel_name_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.
inflect_plural
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.
inflect_singular
As "inflect_plural" above, but for singularizing relationship names. Default behavior is
to utilize "to_S" in Lingua::EN::Inflect::Phrase.
schema_base_class
Base class for your schema classes. Defaults to 'DBIx::Class::Schema'.
schema_components
List of components to load into the Schema class.
result_base_class
Base class for your table classes (aka result classes). Defaults to 'DBIx::Class::Core'.
additional_base_classes
List of additional base classes all of your table classes will use.
left_base_classes
List of additional base classes all of your table classes will use that need to be
leftmost.
additional_classes
List of additional classes which all of your table classes will use.
components
List of additional components to be loaded into all of your Result classes. A good
example would be InflateColumn::DateTime
result_components_map
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 => [
'+YourApp::Schema::Component::RouteChange',
'InflateColumn::DateTime',
],
}
You may use this in conjunction with "components".
result_roles
List of Moose roles to be applied to all of your Result classes.
result_roles_map
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 => [
'YourApp::Role::Building',
'YourApp::Role::Destination',
],
RouteChange => 'YourApp::Role::TripEvent',
}
You may use this in conjunction with "result_roles".
use_namespaces
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).
dump_directory
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
runtime.
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.
dump_overwrite
Deprecated. See "really_erase_my_files" below, which does *not* mean the same thing as
the old "dump_overwrite" setting from previous releases.
really_erase_my_files
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.
overwrite_modifications
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
option.
custom_column_info
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 table object (which stringifies to the unqualified table name), 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".
datetime_timezone
Sets the timezone attribute for DBIx::Class::InflateColumn::DateTime for all columns with
the DATE/DATETIME/TIMESTAMP data_types.
datetime_locale
Sets the locale attribute for DBIx::Class::InflateColumn::DateTime for all columns with
the DATE/DATETIME/TIMESTAMP data_types.
datetime_undef_if_invalid
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.
config_file
File in Perl format, which should return a HASH reference, from which to read loader
options.
preserve_case
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.
qualify_objects
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.
use_moose
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.
only_autoclean
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.
col_collision_map
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.
Examples:
col_collision_map => 'column_%s'
col_collision_map => { '(.*)' => 'column_%s' }
col_collision_map => { '(foo).*(bar)' => 'column_%s_%s' }
rel_collision_map
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
COLLISIONS".
uniq_to_primary
Automatically promotes the largest unique constraints with non-nullable columns on tables
to primary keys, assuming there is only one largest unique constraint.
filter_generated_code
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.
"perltidy".
If this exists but fails to return text matching "/\bpackage\b/", no file will be
generated.
filter_generated_code => sub {
my ($type, $class, $text) = @_;
...
return $new_code;
}
METHODS
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.
new
Constructor for DBIx::Class::Schema::Loader::Base, used internally by
DBIx::Class::Schema::Loader.
load
Does the actual schema-construction work.
rescan
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".
get_dump_filename
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.
tables
Returns a sorted list of loaded tables, using the original database table names.
BASE CLASS: $base_class
monikers
Returns a hashref of loaded table to moniker mappings. There will be two entries for each
table, the original name and the "normalized" name, in the case that the two are different
(such as databases that like uppercase table names, or preserve your original mixed-case
definitions, or what-have-you).
classes
Returns a hashref of table to class mappings. In some cases it will contain multiple
entries per table for the original and normalized table names, as above in "monikers".
generated_classes
Returns an arrayref of classes that were actually generated (i.e. not skipped because
there were no changes).
NON-ENGLISH DATABASES
If you use the loader on a database with table and column names in a language other than
English, you will want to turn off the English language specific heuristics.
To do so, use something like this in your loader options:
naming => { monikers => 'v4' },
inflect_singular => sub { "$_[0]_rel" },
inflect_plural => sub { "$_[0]_rel" },
COLUMN ACCESSOR COLLISIONS
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
md5:
__PACKAGE__->add_column('+can' => { accessor => 'my_can' });
Another option is to use the "col_collision_map" option.
RELATIONSHIP NAME COLLISIONS
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
DBIx::Class.
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.
