From this line:

'AnonymousUser' object has no attribute 'first_name'

I believe your problem is that you didn't regulate the users carefully. AnonymousUser is an object that is representing a user that is not authenticated. For this object, id is none, permissions is an empty array -- basically you won't expect to find any data here.

The thing that you should do is to add this: a login-required decorator. This forces the user to be authenticated properly before proceeding (or just user.is_authenticated() in case you don't want to apply this to the entire view.

If you are logged in and AnonymousUser still persists, you may want to check out other threads regarding this problem like this.
