NAME

       Jifty::Record - Represents a Jifty object that lives in the database.

DESCRIPTION

       "Jifty::Record" is a kind of Jifty::Object that has a database representation; that is, it is also a
       Jifty::DBI::Record as well.

METHODS

   create PARAMHASH
       "create" can be called as either a class method or an object method.

       Takes an array of key-value pairs and inserts a new row into the database representing this object.

       Overrides Jifty::DBI::Record in these ways:

       Remove "id" values unless they are truly numeric
       Automatically load by id after create
       actually stop creating the new record if a field fails to validate.

   id
       Returns the record id value.  This routine short-circuits a much heavier call up through Jifty::DBI

   load_or_create
       "load_or_create" can be called as either a class method or an object method.  It attempts to load a
       record with the named parameters passed in.  If it can't do so, it creates a new record.

   as_create_action PARAMHASH
       Returns the Jifty::Action::Record::Create action for this model class.

       The PARAMHASH allows you to add additional parameters to pass to "new_action" in Jifty::Web.

   as_update_action PARAMHASH
       Returns the Jifty::Action::Record::Update action for this model class. The current record is passed to
       the constructor.

       The PARAMHASH allows you to add additional parameters to pass to "new_action" in Jifty::Web.

   as_delete_action PARAMHASH
       Returns the Jifty::Action::Record::Delete action for this model class. The current record is passed to
       the constructor.

       The PARAMHASH allows you to add additional parameters to pass to "new_action" in Jifty::Web.

   as_search_action PARAMHASH
       Returns the Jifty::Action::Record::Search action for this model class.

       The PARAMHASH allows you to add additional parameters to pass to "new_action" in Jifty::Web.

   _guess_table_name
       Guesses a table name based on the class's last part. In addition to the work performed in
       Jifty::DBI::Record, this method also prefixes the table name with the plugin table prefix, if the model
       belongs to a plugin.

   current_user_can RIGHT [ATTRIBUTES]
       Should return true if the current user ("$self->current_user") is allowed to do RIGHT.  Possible values
       for RIGHT are:

       create
           Called just before an object's "create" method is called, as well as before parameter validation.
           ATTRIBUTES is the attributes that the object is trying to be created with, as the attributes aren't
           on the object yet to be inspected.

       read
           Called before any attribute is accessed on the object.  ATTRIBUTES is a hash with a single key
           "column" and a single value, the name of the column being queried.

       update
           Called before any attribute is changed on the object.  ATTRIBUTES is a hash of the arguments passed
           to _set.

       delete
           Called before the object is deleted.

       Models wishing to customize authorization checks should override this method. You can do so like this:

         sub current_user_can {
             my ($self, $right, %args) = @_;

             # Make any custom checks that return 1 to allow or return 0 to deny...

             # Fallback upon the default implementation to handle the
             # SkipAccessControl configuration setting, superuser, bootstrap,
             # delegation, and the before_access hook
             return $self->SUPER::current_user_can($right, %args);
         }

       If you are sure you don't want your model to fallback using the default implementation, you can replace
       the last line with whatever fallback policy required.

       Authorization steps

       The default implementation proceeds as follows:

       1.  If the "SkipAccessControl" setting is set to a true value in the framework configuration section of
           etc/config.yml, "current_user_can" always returns true.

       2.  The method first attempts to call the "before_access" hooks to check for any allow or denial. See
           "The before_access hook".

       3.  Next, the default implementation returns true if the current user is a superuser or a bootstrap user.

       4.  Then, if the model can perform delegation, usually by using Jifty::RightsFrom, the access control
           decision is deferred to another object (via the "delegate_current_user_can" subroutine).

       5.  Otherwise, it returns false.

       The before_access hook

       This implementation may make use of a trigger called "before_access" to make the decision. A new handler
       can be added to the trigger point by calling "add_handler":

         $record->add_trigger(
             name => 'before_access',
             code => \&before_access,
             abortable => 1,
         );

       The "before_access" handler will be passed the same arguments that were used to call "current_user_can",
       including the current record object, the operation being checked, and any arguments being passed to the
       operation.

       The "before_access" handler should return one of three strings: 'deny', 'allow', or 'ignore'. The
       "current_user_can" implementation reacts as follows to these results:

       1.  If a handler is abortable and aborts by returning a false value (such as "undef"), "current_user_can"
           returns false.

       2.  If any handler returns 'deny', "current_user_can" returns false.

       3.  If any handler returns 'allow' and no handler returns 'deny', "current_user_can" returns true.

       4.  In all other cases, the results of the handlers are ignored and "current_user_can" proceeds to check
           using superuser, bootstrap, and delegation.

   check_create_rights ATTRIBUTES
       Internal helper to call "current_user_can" with "create".

   check_read_rights
       Internal helper to call "current_user_can" with "read".

       Passes "column" as a named parameter for the column the user is checking rights on.

   check_update_rights
       Internal helper to call "current_user_can" with "update".

   check_delete_rights
       Internal helper to call "current_user_can" with "delete".

   as_user CurrentUser
       Returns a copy of this object with the current_user set to the given current_user. This is a way to act
       on behalf of a particular user (perhaps the owner of the object)

   as_superuser
       Returns a copy of this object with the current_user set to the superuser. This is a convenient way to
       duck around ACLs if you have code that needs to for some reason or another.

   delete PARAMHASH
       Overrides Jifty::DBI::Record to check the delete ACL.

   brief_description
       Display the friendly name of the record according to _brief_description.

       To change what this returns, override _brief_description instead.

   _brief_description
       When displaying a list of records, Jifty can display a friendly value rather than the column's unique id.
       Out of the box, Jifty always tries to display the 'name' field from the record.  If there is no 'name'
       field, Jifty falls back to the record id.

       You can override this method to return the name of a method on your record class which will return a nice
       short human readable description for this record.

   null_reference
       By default, Jifty::DBI::Record returns "undef" on non-existent related fields; Jifty prefers to get back
       an object with an undef id.

   _new_collection_args
       Overrides the default arguments which this collection passes to new collections, to pass the
       "current_user".

   _new_record_args
       Overrides the default arguments which this collection passes to new records, to pass the "current_user".

   cache_key_prefix
       Returns a unique key for this application for the Memcached cache.  This should be global within a given
       Jifty application instance.

   since
       By default, all models exist since "undef", the ur-time when the application was created. Please override
       it for your model class.

   printable_table_schema
       When called, this method will generate the SQL schema for the current version of this class and return it
       as a scalar, suitable for printing or execution in your database's command line.

   table_schema_statements
       When called, this method will generate the SQL schema statements for the current version of this class
       and return it as array.

   create_table_in_db
       When called, this method will generate the SQL schema for the current version of this class and insert it
       into the application's currently open database.

   drop_table_in_db
       When called, this method will generate the SQL to remove this model's table in the database and execute
       it in the application's currently open database.  This method can destroy a lot of data. Be sure you know
       what you're doing.

   add_column_sql column_name
       Returns the SQL statement necessary to add "column_name" to this class's representation in the database

   add_column_in_db column_name
       Executes the SQL code generated by add_column_sql. Dies on failure.

   drop_column_sql column_name
       Returns the SQL statement necessary to remove "column_name" from this class's representation in the
       database

   drop_column_in_db column_name
       Executes the SQL code generated by drop_column_sql. Dies on failure.

   schema_version
       This method is used by Jifty::DBI::Record to determine which schema version is in use. It returns the
       current database version stored in the configuration.

       Jifty's notion of the schema version is currently broken into two:

       1.  The Jifty version is the first. In the case of models defined by Jifty itself, these use the version
           found in $Jifty::VERSION.

       2.  Any model defined by your application use the database version declared in the configuration. In
           etc/config.yml, this is located at:

             framework:
               Database:
                 Version: 0.0.1

       A model is considered to be defined by Jifty if it the package name starts with "Jifty::". Otherwise, it
       is assumed to be an application model.

   column_serialized_as
   default_serialized_as_columns
   jifty_serialize_format
       This is used to create a hash reference of the object's values. Unlike Jifty::DBI::Record->as_hash, this
       won't transform refers_to columns into JDBI objects. Override this if you want to include calculated
       values (for use in, say, your REST interface)

   autogenerate_action
       Controls which of the Jifty::Action::Record subclasses are automatically set up for this model; this
       subroutine is passed one of the strings "Create", "Update", "Delete", "Search" or "Execute", and should
       return a true value if that action should be autogenerated.

       The default method returns 0 for all action classes if the model is marked as "is_private".  It returns 0
       for all actions that are not "Search" if the model is marked as "is_protected"; otherwise, it returns
       true.

   is_private
       Override this method to return true to not generate any actions for this model, and to hide it from REST
       introspection.

   is_protected
       Override this method to return true to only generate Search actions for this model.

   enumerable
       Controls whether autogenerated actions with columns that refer to this class should attempt to provide a
       drop-down of possible values or not.  This method will be called as a class method, and defaults to true.
