Instance Method Details

#acts_as_access_object(options = {}) ⇒ Object

Extend self with access object capabilites. See README for details on usage. Accepts the following options as a hash:

grouped_by

name of the association acting as a group for access privilege

group_class_name

class name of group class

join_table

name of the join table

foreign_key

foreign key of self in the join table

association_foreign_key

foreign_key of the group class

habtm

set to true if the grup is joined with a habtm association.

If not specified, the plugin tries to guess if the association is has_and_belongs_to_many or belongs_to by creating the singular form of the :grouped_by option and comparing it to itself: If it matches, it assumes a belongs_to association.
