AbstractController::Base is a low-level API. Nobody should be using it directly, and subclasses (like ActionController::Base) are expected to provide their own render method, since rendering means different things depending on the context.

Define a controller as abstract. See internal_methods for more details.

# File actionpack/lib/abstract_controller/base.rb, line 27 def abstract! @abstract = true end
A list of method names that should be considered actions. This includes all public instance methods on a controller, less any internal methods (see #internal_methods), adding back in any methods that are internal, but still exist on the class itself. Finally, #hidden_actions are removed.
Returns
-
array - A list of all methods that should be considered actions.

# File actionpack/lib/abstract_controller/base.rb, line 61 def action_methods @action_methods ||= begin # All public instance methods of this class, including ancestors methods = public_instance_methods(true).map { |m| m.to_s }.to_set - # Except for public instance methods of Base and its ancestors internal_methods.map { |m| m.to_s } + # Be sure to include shadowed public instance methods of this class public_instance_methods(false).map { |m| m.to_s } - # And always exclude explicitly hidden actions hidden_actions # Clear out AS callback method pollution methods.reject { |method| method =~ /_one_time_conditions/ } end end
action_methods are cached and there is sometimes need to refresh them. clear_action_methods! allows you to do that, so next time you run action_methods, they will be recalculated

# File actionpack/lib/abstract_controller/base.rb, line 80 def clear_action_methods! @action_methods = nil end
Returns the full controller name, underscored, without the ending Controller. For instance, MyApp::MyPostsController would return “my_app/my_posts” for controller_name.
Returns
-
string
[ show source ]
# File actionpack/lib/abstract_controller/base.rb, line 90 def controller_path @controller_path ||= name.sub(/Controller$/, '').underscore unless anonymous? end
The list of hidden actions to an empty array. Defaults to an empty array. This can be modified by other modules or subclasses to specify particular actions as hidden.
Returns
-
array - An array of method names that should not be considered actions.
[
]A list of all internal methods for a controller. This finds the first abstract superclass of a controller, and gets a list of all public instance methods on that abstract class. Public instance methods of a controller would normally be considered action methods, so methods declared on abstract classes are being removed. (ActionController::Metal and ActionController::Base are defined as abstract)

Delegates to the class’ controller_path
[ show source ]
# File actionpack/lib/abstract_controller/base.rb, line 123 def controller_path self.class.controller_path end
Calls the action going through the entire action dispatch stack.
The actual method that is called is determined by calling #method_for_action. If no method can handle the action, then an ActionNotFound error is raised.
Returns
-
