I tried looking for an answer to this question, but to no avail.

I'm getting this error message when I run rails test.

 1) Error:
UsersLoginTest#test_login_with_valid_information_followed_by_logout:
ActionView::Template::Error: invalid hash
 app/models/user.rb:32:in `new'
 app/models/user.rb:32:in `authenticated?'

 test/integration/users_login_test.rb:45:in `block in <class:UsersLoginTest>'

24 runs, 66 assertions, 0 failures, 1 errors, 0 skips

Here are the relevant files, any help would be greatly appreciated

Thanks!

Edit: I won't allow any me to post anymore code, so if there's anything you'd need to see, let me know!

"BCrypt::Errors::InvalidHash" when trying to sign in Looks like the same issue you're encountering:

This means that the hash stored in password_digest is not a valid BCrypt hash (including if the field is empty).

Based on the comments, it looks like you just created the user at a time the has_secure_password wasn't there, so the password digest never got stored. Look in the database, you'll probably see that password_digest is empty for that user. Remove the user from the database and re-create with your new working code and it should work.
