Devise - logging on with something other than email

I have followed the instructions on this page https://github.com/plataformatec/devise/wiki/How-To:-Allow-users-to-sign-in-with-something-other-than-their-email-address to allow signing in with something other than the email, but when I try to login I get an error of unidentified method for the new key I am using. In this case student_id. I am able to create an account with the student id and email just fine.

In application_controller.rb I have added the parameters for both sign up and sign in.

  before_action :configure_permitted_parameters, if: :devise_controller?

  private

    def configure_permitted_parameters
        devise_parameter_sanitizer.permit(:sign_up, keys: [:student_id, :email, :password, :password_confirmation])
        devise_parameter_sanitizer.permit(:sign_in, keys: [:student_id, :password])
    end

In the devise initializer I have added the link config.authentication_keys = [:student_id]

Not sure what else I am missing, and don't know enough to read into the error all that well.

Can you post the actual error?

That might have been helpful. Here is the error:

Interesting, so the error was on the ActionDispatch Request object. Can you click the full trace tab and screenshot that too? Assuming your form passes in the student_id, I'd assume that'd be available.

Obvious thing: Did you restart Rails after changing the initializer?

Yes I did restart rails a few times to make sure it wasn't something silly like that.

The full trace can be found here - http://www.awesomescreenshot.com/image/2486026/389892e4c6723ca10f0a40718c89bdba

I figured. Hmm. This guy overrode the method to include a scope to fix his. https://github.com/plataformatec/devise/issues/3357

I know I've added a login key to this before without having to do this though.

I had the config.resource_keys uncommented for some reason and once I commented it out all worked as expected.

Thanks for your help here Chris.

Interesting, glad you got it! :D
