“Could not find a valid mapping for #” only on second and successive tests

Question

I\'m trying to write a request test that asserts that the proper links appear on the application layout depending in whether a user is logged in or out. FWIW, I\'m using Dev

Answer 1

I had this happen to me before when I signed in as a test user on one of my apps and had made some test uploads and test posts. I then deleted that test user and when I tried to sign up again with the same test user I was displayed the message "Could not find a valid mapping for nil". What I did to solve it was to delete all of the test uploads and test post that I had made as that test user. I then tried to sign up again and it worked. By that way a faster and easier way to delete stuff is by using db browser for sqlite.
