Hello!
I'm starting with django framework; I use django 1.0 and sqlite
database backend.
I've stumbled upon this thing: when editing model entry with ModelForm
I get insert instead of update.
Here's view procedure:
=============================================================================
def edit(request, task_id):
if request.method == 'POST':
if task_id == -1:
form = NewTaskForm(data=request.POST, instance=None)
if form.is_valid():
form.save()
else:
try:
task = Task.objects.get(pk=task_id)
form = NewTaskForm(data=request.POST,
instance=task)
if form.is_valid():
form.save()
except Task.DoesNotExist:
raise Http404
return HttpResponseRedirect(get_test_app_url())
else:
if task_id == -1:
form = NewTaskForm()
else:
try:
task = Task.objects.get(pk=task_id)
form = NewTaskForm(instance=task)
except Task.DoesNotExist:
raise Http404
return render_to_response('test_app/edit.html', { 'form' : form
})
=============================================================================
test_app/edit.html looks like this:
=============================================================================
<form action="/py/test_app/edit/" method="POST">
{{ form.as_p }}
<input type="submit" value="Save" />
</form>
=============================================================================
I guess I miss some obvious thing. Please help to spot it.
