Defined in:

Overview

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

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

map.cullender_for :events
mapping = Cullender.mappings[:event]

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

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

mapping.to   #=> Event
# 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

  raise "Could not find a valid mapping for path #{path.inspect}"
end

.find_scope!(duck) ⇒ Object
