Instance Method Details

#auto_close_bb_tags(options = {}) ⇒ Object

Closes tags on text attributes. Closes tags before save by default, but can be overridden by passing :on; the :on paramater accepts :save, :create, :update, :validation. Alternatively, pass :no_callback => true to prevent tags from being closed automatically (you will have to close them in the controller). If custom mass_assignment is used such as attr_accessible :foo, :as => :bar pass :mass_assignment_keys => :bar or :mass_assignment_keys => [:bar, :baz].

#taggable_fields ⇒ Object

ActiveRecord text attributes are considered taggable by default. Using auto_close_bb_tags_for overrides default attributes with custom attributes.
