Overview

Responsible for handling devise mappings and routes configuration. Each resource configured by devise_for in routes is actually creating a mapping object. You can refer to devise_for in routes for usage options.

The required value in devise_for is actually not used internally, but it’s inflected to find all other values.

map.devise_for :users
mapping = Devise.mappings[:user]

mapping.name #=> :user
# is the scope used in controllers and warden, given in the route as :singular.

mapping.as   #=> "users"
# how the mapping should be search in the path, given in the route as :as.

mapping.to   #=> User
# is the class to be loaded from routes, given in the route as :class_name.

mapping.modules  #=> [:authenticatable]
# is the modules included in the class

Class Method Details

.add_module(m) ⇒ Object

def confirmable?
  self.modules.include?(:confirmable)
end

end

.find_scope!(duck) ⇒ Object

Receives an object and find a scope for it. If a scope cannot be found, raises an error. If a symbol is given, it’s considered to be the scope.
