Sounds like you want:
for field in request.user.get_profile()._meta.fields:
print getattr(request.user.get_profile(), field.name)
Some additional notes regarding your solution, and other suggestions:
- __getattr__ is an internal method, and shouldn't be invoked
directly. Like all double underscore methods, it indicates that the
method is part of a protocol - you should be using the protocol,
rather than invoking the method directly.
- The eval() technique suggested in another reply may work, but isn't
really a good practice. eval() exists to make interactive prompts
possible, not as a general programming technique. There is no
protection on what eval() will do, so if an attacker can modify the
string that is being eval()'d, they have complete access to your
system. This is obviously very bad practice on a public-facing
interface, like a web site.
