login_path vs. new_user_session_path

The video doesn't explain why we cant use login_path vs. new_user_session_path very well. I looked at rake routes and they have the same Controller Action.. what gives?

OK, when you run rake routes, look in the middle column. This tells you what URI pattern is used for both paths and they are different. One is /login(.:format) and the other one is /users/sign_in(.:format). If your controller is set to redirect to one of them, the test will only succeed if it checks the very same path/URI. At some point your before_action :authenticate_user! in Devise was set to redirect to one of those particular paths, not the other. I think new_user_session_path is Devise's default. I'm sure there are ways to change that behavior, you just have to dig in the documentation ;).

I understood the rake routes differences but I couldn't understand why the redirect was one path over the other. Thank you...that cleared up a lot!

These are the same paths, the login_path is just customized to look better - login_path sounds much better than new_user_session_path when you just look at it and want to infer its function :). There's a lot of stuff you can do with paths in Rails.

Thanks for the fast response!

I guess what I'm asking is why the test fail if I tried to use login_path vs. new_user_session_path.

I know we created the login path through our config routes. What part of the code is looking specifically for the new_user_session_path in our test?

Can you show me your code? On github preferably. I can't blindly assess your particular case.

I will provide a link below.. I am still new to github so I'm not sure if this is the best way to access it but
