Question

I need to trigger callback before Devise redirects user to login page, probably because authenticate_user! method detected he’s not logged in. Something like:

before_filter :authenticate_user!, :only => :edit

def not_authenticated_callback
  # do something
end

It shouldn’t be called if authenticate_user! has not been called.

I’ve found an ugly solution:

around_filter :intersect_warden

def intersect_warden
  success = false
  result = catch(:warden) do
    result = yield
    success = true
    result
  end

  unless success
    not_authenticated_callback
    throw(:warden, result)
  end
end
