I am currently working on views for user administration. When I go to the view to create a new user, there is always the login name and password already filled in. I wondered where those values came from. I printed the values of the User model. It was empty. Was there an object which masked those values? Luckily I finally realized that it was the browser autocompletion, after inserting an autocomplete=”off” attribute to the input like described on Selfhtml, the entries in the form were empty.
