Hi folks,
I was trying to create a simple python login, but it seems does not work for me, here is the code i have done:
It works and shows the log in page. Now i can log in with the user name and pass correct, but if i put wrong pass or username then it doesn't say "Invalid username or password". I really want it say that "invalid username or password" with the log in form again but i have tried but it never work for me. Anyone has any idea? thanks first.
