As expected, it works if i set the values in my view:
action = get_object_or_404(Action, pk=action_id)
form=ActionForm(instance=action)
if request.method == 'POST':
form = ActionForm(request.POST, action)
if form.is_valid():
edit_action=form.save(commit=False)
edit_action.call = action.call
edit_action.date_created = action.date_created
edit_action.id = action.id
edit_action.save()
form.save_m2m()
return HttpResponseRedirect(reverse(call_detail,
kwargs={"call_id": action.call.id})) # Redirect after POST
return render_to_response('management/action_edit.html',
{'form': form, 'action': action},
context_instance=RequestContext(request))
I'm not sure if this is the best way to solve the problem.
Also, it seems strange that one needs to add the action to the ActionForm
but yet, have to set the 3 missing fields anyway (call, date_created and id)
If i don't assign the id, then a new action is made instead of an old
one update.
Could this be a bug? If not how come i need to manually set those fields
or else i get an error?
