You can define a simple middleware to put attributes on a request. Eg:

class MyMiddleware(object):
def process_request(request):
request.profile = None
if request.user.is_authenticated():
request.profile = request.user.get_profile()

See the documentation on middleware:

https://docs.djangoproject.com/en/1.4/topics/http/middleware/

Note that anything you put in TEMPLATE_CONTEXT_PROCESSORS is run
whenever you render a template, and anything in MIDDLEWARE_CLASSES
will be run on each request, so make sure the things you do in those
places are actually required every time you render a template /
process a request.
