</div>You can define a simple middleware to put attributes on a request. Eg=
:<br>
<br>
class MyMiddleware(object):<br>
=A0 def process_request(request):<br>
=A0 =A0 request.profile =3D None<br>
=A0 =A0 if request.user.is_authenticated():<br>
=A0 =A0 =A0 request.profile =3D request.user.get_profile()<br>
<br>
See the documentation on middleware:<br>

arget=3D"_blank">https://docs.djangoproject.com/en/1.4/topics/http/middlewa=
re/</a><br>
<br>
Note that anything you put in TEMPLATE_CONTEXT_PROCESSORS is run<br>
whenever you render a template, and anything in MIDDLEWARE_CLASSES<br>
will be run on each request, so make sure the things you do in those<br>
places are actually required every time you render a template /<br>
process a request.<br>
