305 Catalyst::Authentication::Store::DBIx::Class::User - The backing user
306 class for the Catalyst::Authentication::Store::DBIx::Class storage
311 This documentation refers to version 0.1503.
315 Internal - not used directly, please see
316 L<Catalyst::Authentication::Store::DBIx::Class> for details on how to
317 use this module. If you need more information than is present there, read the
324 The Catalyst::Authentication::Store::DBIx::Class::User class implements user storage
325 connected to an underlying DBIx::Class schema object.
327 =head1 SUBROUTINES / METHODS
333 =head2 load ( $authinfo, $c )
335 Retrieves a user from storage using the information provided in $authinfo.
337 =head2 supported_features
339 Indicates the features supported by this class. These are currently Roles and Session.
343 Returns an array of roles associated with this user, if roles are configured for this user class.
347 Returns a serialized user for storage in the session.
351 Revives a serialized user from storage in the session.
353 =head2 get ( $fieldname )
355 Returns the value of $fieldname for the user in question. Roughly translates to a call to
356 the DBIx::Class::Row's get_column( $fieldname ) routine.
360 Retrieves the DBIx::Class object that corresponds to this user
364 Synonym for get_object
368 This is called when the auto_create_user option is turned on in
369 Catalyst::Plugin::Authentication and a user matching the authinfo provided is not found.
370 By default, this will call the C<auto_create()> method of the resultset associated
371 with this object. It is up to you to implement that method.
375 This is called when the auto_update_user option is turned on in
376 Catalyst::Plugin::Authentication. Note that by default the DBIx::Class store
377 uses every field in the authinfo hash to match the user. This means any
378 information you provide with the intent to update must be ignored during the
379 user search process. Otherwise the information will most likely cause the user
380 record to not be found. To ignore fields in the search process, you
381 have to add the fields you wish to update to the 'ignore_fields_in_find'
382 authinfo element. Alternately, you can use one of the advanced row retrieval
383 methods (searchargs or resultset).
385 By default, auto_update will call the C<auto_update()> method of the
386 DBIx::Class::Row object associated with the user. It is up to you to implement
387 that method (probably in your schema file)
391 Delegates method calls to the underlying user row.
395 Delegates handling of the C<< can >> method to the underlying user row.
397 =head1 BUGS AND LIMITATIONS
399 None known currently, please email the author if you find any.
