Template rendering fails when both form data and a tuple are passed to
render_to_response.
Python: 2.6.2; Django: 1.1; Environment: Windows + built-in dev server
I use the standard django.contrib.auth.models.User and .Group models.
View:
class FuksiForm(forms.Form):
ryhmat = forms.ModelChoiceField(queryset=Group.objects.none(),
empty_label = "Ei saapunut")
def __init__ (self, qset):
super(FuksiForm, self).__init__(qset)
self.fields["ryhmat"].queryset = qset
def fuksit(request, ohjelma_id):
if request.method == 'POST': # If the form has been submitted...
form = FuksiForm(request.POST) # A form bound to the POST data
if form.is_valid(): # All validation rules pass
msg = 'meh'
return HttpResponse(msg)
else:
users = User.objects.filter(ryhma__nimi__startswith=ohjelma_id)
groups = Group.objects.filter(name__startswith=ohjelma_id)
form = FuksiForm(qset = groups)
d = {'form': form, 'pf': users}
Template:
<table>
{% for u in pf %}
<tr>
<td>{{ u.first_name }} {{ u.last_name }}</td>
<td>{{ u.username }}</td>
<td>{{ form.ryhmat.errors }} <label
for="id_ryhmat">Ryhma</label>
{{ form.ryhmat }}</td>
</tr>
{% endfor %}
</table>
This produces: http://users.tkk.fi/jjpelto3/exception.html
When either form or pf are removed from the dictionary, the program
works fine. However, everything seems to be fine until
render_to_response when I do debugging in the shell.
I suspect a bug in the rendering handler, since people on #django were
unable to help either. There are no documented similar cases.
I am utterly perplexed. Please help. :)
