Devise: undefined method `user_signed_in?' for ApplicationController:Class?

So I'm marking this as a community wiki since the solution is trivial.

I'm getting the above error with Rails 3.1.1 and Ruby 1.9.2. I've spent the last hour looking and the main things I've found were: clear_helpers in ApplicationController can cause the helpers to not load. My code isn't using that and I don't believe the gems I've installed are either.

Missing devise_for in routes.rb. I have devise_for :users Missing 'database_authenticatable' in my Users model. I have in my users.

Rb : devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable My behavior matches exactly what's described in this email thread except signed_in? :user doesn't work for me either. However, Devise.

Mappings does show the user mapping. Any ideas on what could be wrong? Even a hack for current_user would help me greatly as I have to get some functionality running ASAP.

So I'm marking this as a community wiki since the solution is trivial. I was calling debugger (which I used to check current_user with the following code class ApplicationController . Long story short, make sure you're not trying to call it within a controller definition but within the controller instance.

Number 3 strikes me as odd. Is your model file named users. Rb?

Is your class declaration Users user. Rb User.

It's actually user. Rb and that was a typo on my part. Good eye, though.

It actually was working and I was calling current_user and user_signed_in? In the wrong context – Eric Hu Oct 13 '11 at 22:12 What do you mean by wrong context? – Ken Oct 13 '11 at 22:54 See my answer above.

I was calling it in the declaration of a controller instead of within an instance of a controller. – Eric Hu Oct 14 '11 at 2:19.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
