Cannot access /users/sign_up in "Generating the Devise Views"

Hi Patrick, it looks like things are working correctly, the problem is how the sign_out route works.

HTTP GET requests are for doing just that, getting information. A GET request shouldn't "change" anything. That's why most forms are POST forms, because POST is meant to change things.

Signing out "Changes" something, you change from being signed-in to signed-out. It's ill-advised to ever have a sign-out link accessible via GET. Because GET is supposed to be safe, some browsers could pre-fetch GET links for speed, but if it prefetched /sign-out, it would sign you out.

Because of that, the default sign_out path is an HTTP DELETE request. So by visiting /users/sign_out, you are GETing a path that is meant to be DELETEd. We end up creating a button that performs the correct action.

In the meantime you could clear your cookies, or go into private/incognito mode to sign yourself out.

Hope that helps

Keep watching the video and he should explain what do do next.

Since you are logged out the erb link "link_to currrent_user.full_name does not exist anymore"

Also try opening an incognito browser if you are using chrome.

Hey Jim!

Love the work you and Jason are doing!

Yes, realize now why it makes sense that a GET request for /users/sign_out doesn't work by default. You explained that well in a later lesson. :)

My question was just about the continuity in the lesson "Generating the Devise Views" — I believe I was following the tutorial properly, but was unable to go to the user sign_in page (as instructed in the video) because I was signed in, and the part where we end up setting up the delete method for sessions didn't come until later.

Maybe it is because I may have checked "Remember Me" the first time I signed in? Just wanted to bring up an issue I had when following the videos that led me to need to open a new browser / incognito window.

Also, would love to see you guys do a set of Drupal videos some day—have tried to learn Rails before, and have never stuck with something the same way I am with your videos. Would love to see the same kind of tutorials for Drupal.

Thanks, Patrick

I see. Manually testing authentication is tricky for exactly that reason. I'm not sure why in the video we may have been signed out, while you were still signed in. The remember me could have something to do with it, or we may have somehow cleared our cookies. It happens.

Typically when implementing, the order to do it in is "Register, sign-out, sign-in", because you obviously need to register first, but then you may be stuck "signed-in" until you can get sign-out working. Then its feasible to implement the sign-in form.

If you haven't implemented sign-out and you need to sign out, clearing cookies is the way to go.
