I am writing a web app that displays user profiles.
The profile includes a display of the user's interest in other users, which can be uni- or bidirectional. I am using django's included User model to handle authentication and authorization.
The problem I have is that under some circumstances the rendered pages present data from queries executed earlier. Specifically, this happens when I am using the app as two different users on the same computer but on different browsers (Chrome and Safari on OS X; using the django development web server). Right after I load a page for user 1, if I reload a page for user 2 I see user 1's query results.
I have confirmed that my queries are correct by printing them to the console. I think the problem may be at the web server, because the pages load the right queries right after a server restart.
Any ideas?
** Edit: as Daniel points out, the problem is that the interest_view function has a dictionary as a default parameter.**
Relevant code snippets:
models.py
class Profile(UserenaBaseProfile):
user = models.OneToOneField(User, unique=True)
class Interest(models.Model):
user = models.ForeignKey(User, related_name=u'interests')
interest = models.ForeignKey(User)
views.py
from django.http import HttpResponseForbidden
from django.shortcuts import get_object_or_404, render_to_response
from django.template import RequestContext
def interest_view(request, username, extra_context={}):
user = get_object_or_404(User, username__iexact=username)
profile = user.get_profile()
if not profile.can_view_profile(request.user):
return HttpResponseForbidden("You can't view this page.")
interests = Interest.objects.filter(user=user)
if len(interests) > 0:
extra_context['active_interests'] = interests
return render_to_response('interest_detail.html',
extra_context,
context_instance=RequestContext(request)
)
interest_detail.html
{% if active_interests %}
{% for interest in active_interests %}
<li>
{{ interest.interest.first_name }} {{ interest.interest.last_name }}
</li>
{% endfor %}
{% endif %}
