Generating the Devise Views : Empty :first_name, :last_name and :profile_name

Do you have this in your application controller? If not, paste it in, save it, and try it again. There are differences in Rails 3 (which the vide are using) and Rails 4 which some of us have been using. Too bad Treehouse hasn't as much as made a guide/blog post about it. Or if they have, I can't find it and it should be in the guide somewhere.

code:

class ApplicationController < ActionController::Base before_filter :configure_permitted_parameters, if: :devise_controller? # Prevent CSRF attacks by raising an exception. # For APIs, you may want to use :null_session instead. protect_from_forgery with: :exception

protected

def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:first_name, :last_name, :profile_name,
                                                                                      :email, :password, :password_confirmation) }
end

end

You could try populating db info in the rails console?

In console, I have :

Started POST "/users" for 127.0.0.1 at 2013-09-05 15:53:25 +0200

Unpermitted parameters: first_name, last_name, profile_name

Thank you very much, It's working pretty well ! Thanks for answering so fast :)
