Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(*args, &block) ⇒ Object

def method_missing(*args, **kwargs, &block)
  @target.send(*args, **kwargs, &block)
end

Instance Method Details

#to_json(options = nil) ⇒ Object

Override to_json to always call to_json on the target object, instead of serializing the proxy object, that may issue circular references on Ruby 1.8.

def to_json(options = nil)
  @target.to_json(options)
end

#to_model ⇒ Object

Override to_model to always return the proxy, otherwise it returns the target object. This allows us to integrate with action view.

end

#to_param ⇒ Object

Override to_param to always return the proxy.to_param. This allow us to integrate with action view.

end

#try(*a, &b) ⇒ Object

Allow calling localized methods with :try. If the method is not declared here, it’ll be delegated to the target, losing localization capabilities.
