Overview
== Active Model Conversions
Handles default conversions: to_model, to_key, to_param, and to_partial_path.
Let's take for example this non-persisted object.
class ContactMessage include ActiveModel::Conversion
# ContactMessage are never persisted in the DB
def persisted?
false
end
end
cm = ContactMessage.new cm.to_model == self # => true cm.to_key # => nil cm.to_param # => nil cm.to_path # => "contact_messages/contact_message"

Instance Method Summary collapse
-
#to_key ⇒ Object
Returns an Enumerable of all key attributes if any is set, regardless if the object is persisted or not.
-
#to_model ⇒ Object
If your object is already designed to implement all of the Active Model you can use the default :to_model implementation, which simply returns self.
-
#to_param ⇒ Object
Returns a string representing the object's key suitable for use in URLs, or nil if persisted? is false.
-
#to_partial_path ⇒ Object
Returns a string identifying the path associated with the object.

#to_key ⇒ Object
Returns an Enumerable of all key attributes if any is set, regardless if the object is persisted or not.
Note the default implementation uses persisted? just because all objects in Ruby 1.8.x responds to :id.

#to_model ⇒ Object
If your object is already designed to implement all of the Active Model you can use the default :to_model implementation, which simply returns self.
If your model does not act like an Active Model object, then you should define :to_model yourself returning a proxy object that wraps your object with Active Model compliant methods.

#to_partial_path ⇒ Object
Returns a string identifying the path associated with the object. ActionPack uses this to find a suitable partial to represent the object.
