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.

abstract!()

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

# File actionpack/lib/abstract_controller/base.rb, line 29
def abstract!
  @abstract = true
end
action_methods()

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 63
def action_methods
  @action_methods ||= begin
    # All public instance methods of this class, including ancestors
    methods = (public_instance_methods(true) -
      # Except for public instance methods of Base and its ancestors
      internal_methods +
      # Be sure to include shadowed public instance methods of this class
      public_instance_methods(false)).uniq.map { |x| x.to_s } -
      # And always exclude explicitly hidden actions
      hidden_actions.to_a

    # Clear out AS callback method pollution
    methods.reject { |method| method =~ %r_one_time_conditions/ }
  end
end
clear_action_methods!()

::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 82
def clear_action_methods!
  @action_methods = nil
end
controller_path()

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

Source: show | on GitHub 

# File actionpack/lib/abstract_controller/base.rb, line 92
def controller_path
  @controller_path ||= name.sub(%rController$/, '').underscore unless anonymous?
end
hidden_actions()

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.

Source: show | on GitHub 

# File actionpack/lib/abstract_controller/base.rb, line 51
def hidden_actions
  []
end
internal_methods()

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)

Source: show | on GitHub 

# File actionpack/lib/abstract_controller/base.rb, line 39
def internal_methods
  controller = self
  controller = controller.superclass until controller.abstract?
  controller.public_instance_methods(true)
end

Source: show | on GitHub 

# File actionpack/lib/abstract_controller/base.rb, line 129
def action_methods
  self.class.action_methods
end
available_action?(action_name)

Returns true if a method for the action is available and can be dispatched, false otherwise.

Notice that action_methods.include?("foo") may return false and available_action?("foo") returns true because available action consider actions that are also available through other means, for example, implicit render ones.

# File actionpack/lib/abstract_controller/base.rb, line 140
def available_action?(action_name)
  method_for_action(action_name).present?
end
controller_path()

Delegates to the class’ controller_path

Source: show | on GitHub 

# File actionpack/lib/abstract_controller/base.rb, line 125
def controller_path
  self.class.controller_path
end
process(action, *args)

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

  • self

Source: show | on GitHub 

# File actionpack/lib/abstract_controller/base.rb, line 112
def process(action, *args)
  @_action_name = action_name = action.to_s

  unless action_name = method_for_action(action_name)
    raise ActionNotFound, "The action '#{action}' could not be found for #{self.class.name}"
  end

  @_response_body = nil

  process_action(action_name, *args)
end
