.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*.
+insert_at+  - Integer representing the order in which this module's model will be included

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')
Devise.add_module(:party_module, insert_at: 0)
