I do not see how this can possibly be working for you,
Presumably User is the django.contrib.auth User model,
in which case it has no attribute full_name (you probably
meant get_full_name()). Thus, an AttributeError should
be raised, and your program should crash.

I suspect that you have not shown us the real code, and
you are instead catching all exceptions, which would
explain the behaviour that you are seeing, as your exception
handling code then simply replaces the original value.
