Class Method Details

.add_mapping(resource, options) ⇒ `Object`

end

.add_module(module_name, options = {}) ⇒ `Object`

Make Devise aware of an 3rd party Devise-module (like invitable). For convenience.

Options:

+model+      - String representing the load path to a custom *model* for this module (to autoload.)
+controller+ - Symbol representing the name of an existing or custom *controller* for this module.
+route+      - Symbol representing the named *route* helper for this module.
+strategy+   - Symbol representing if this module got a custom *strategy*.

All values, except :model, accept also a boolean and will have the same name as the given module name.

Examples:

Devise.add_module(:party_module)
Devise.add_module(:party_module, :strategy => true, :controller => :sessions)
Devise.add_module(:party_module, :model => 'party_module/model')
