Is it possible in Rails to check whether a redirect or render had already been issued?

Question

Ruby 2.0.2, Rails 4.0.3, Sorcery 0.8.5

I tried to issue a redirect in my code, only to receive the error message that a redirect or render had already been issued.

You can call performed? in your controller to check if render or redirect_to has been called already:

performed?               # => false
redirect_to(login_path)
performed?               # => true 

Read more about performed? in the Rails docs.
