Devise Completed 401 Unauthorized in 1ms after apply strong parameter

Question

I just configured strong parameter in my app, all seems to be fine. But my devise login failed. I can still register a user and that will login the user in. I am on devise 3.1.1

I added to application_controller:

   before_filter :configure_permitted_parameters, if: :devise_controller? 

     protected
      def configure_permitted_parameters
        devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:email, :password, :remember_me) }
        devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username, :email, :password) }
      end

In my model

   devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable, :token_authenticatable, :invitable, :invite_for => 2.weeks, :authentication_keys => [:username]

And my log, there is a DEPRECATION WARNING: devise :token_authenticatable is deprecated., not sure if this is the problem?

Answer 1

You are using the username as the mode of authentication in your devise model

:authentication_keys => [:username]

where as in your sign-in,you have email for authentication. Try changing your permitted parameters from

 devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:email, :password, :remember_me) } 

to

devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:username, :password, :remember_me) }

Also modify config/initializers/devise.rb to have:

config.case_insensitive_keys = [ :email, :username ]
config.strip_whitespace_keys = [ :email, :username ]
