Rails Check if Controller Index Exists

Question

Is there a way to check if there exists an index action for a controller? Something like:

Controller.indexActionExists?

I have seen posts to check if specific routes exist, but those methods aren't working for me, since some of my index actions aren't associated with routes.

Answer 1

The action_methods method is going to be the most expedient tool in this case, returning a Set of method names. Give the following code a shot:

# Get a set of method names belonging to a controller called 'MyController'

methods = MyController.action_methods

if methods.include? "index"
  puts "MyController has an index method"
else
  puts "MyController lacks an index method"
end
