Thanks for the reply.
I have a views.py like this:
@login_required
def update_transaction(request, tpin=None):
qs = Q(my_institution=None) |
Q(my_institution=request.user.get_profile().my_institution)
txn = get_object_or_404(Transaction.objects.filter(qs), tpin=tpin)
context = {'page_title': 'Update Transactions'}
if request.POST:
update_form = TransactionUpdateForm(request.POST, instance=txn)
if update_form.is_valid():
update_form.save()
return HttpResponseRedirect(reverse('search-txn'))
else:
update_form = TransactionUpdateForm(instance=txn)
context['txn'] = txn
context['form'] = update_form
return render_to_response("update_transaction.html", context,
context_instance=RC(request))
At what point do I do: update_form.get_branch_name_display()? In forms.py or
views.py? Where?
It seems to me that get_FOO_display() is meant to display the values set by
the user. This is not what I'm looking to do. What I got stuck with is that
the tuple values are not displayed as options in the form select
field(choices).
Thanks
