Detect in Rails after_filter whether we're rendering or redirecting

Question

I'm writing an after_filter in Rails 3, and I'd like to detect whether or not the controller (or any other filter) has issued a redirect. Is there any way to do this?

Answer 1

You could look at the status code. 200 is a render, 302 is a redirect.

after_filter :what_happened

protected

def what_happened
  was_redirect = self.status == 302
  was_render = self.status == 200
end
