I'm just not getting this. I've looked at many examples and can't seem
to pass a hidden value into a form.
The problem is that I initially get to the form with GET, and then
instantiate the form with PUT. The key that I need is part of the
original URL, and I'm trying to push it down into the PUT data as
well, but failing.
I have
(r'^fences/newFence/(?P<auth_id>.*)$', 'newFence'),
class newFenceForm(forms.Form):
teaser = forms.CharField(max_length=40)
url = forms.CharField()
address = forms.CharField()
range = forms.IntegerField()
auth_id = forms.CharField(widget=forms.HiddenInput)
def newFence(request, auth_id):
if request.method == 'POST': # if the form has been submitted
form = newFenceForm(request.POST)
if form.is_valid():
# do the geocoding
print form.cleaned_data['auth_id']
print form.cleaned_data['teaser']
print form.cleaned_data['url']
print form.cleaned_data['address']
print form.cleaned_data['range']
# save the object
u = User.objects.filter(auth_id = id)
# show them the new map
return HttpResponseRedirect('../../fences/fenceMap/
%s'%auth_id)
else:
print auth_id
form = newFenceForm({'auth_id' : auth_id})
return render_to_response("map/newfence.html", {'form': form, })
I call this with, say, '.../newFence/chris' and the first time through
it prints 'chris' and instantiates the empty form. But where my
template says
<input type="hidden" name="auth_id" value="{{auth_id}}"
id="id_auth_id" />
the string between curlies is always empty.
What trick am I missing to get that data initiated? Should a
HiddenInput widget be rendered differently in the template?
(I'm happy to take suggestions for a different way to crack this, too
- the problem is that I have to do some post processing on the input
data before creating the object, or I'd use a generic view.)
Thanks.
