Question

I’m trying to catch an exception but does not work.This is the code in my view:

@login_required 
def activities_edit(request, edit):

    ActivityFormSet = modelformset_factory(Activity, can_delete=True)
    act_edit= Activity.objects.filter(campaing=1).get(pk=edit)
    try:
        if act_edit:
            if request.method == 'POST':
                formset = ActivityFormSet(request.POST, request.FILES, queryset=Activity.objects.filter(pk=edit))       
                if formset.is_valid():
                    formset.save()
                    return HttpResponseRedirect('/activities/')
            else:
                formset = ActivityFormSet(queryset=Activity.objects.filter(pk=edit))
    except act_edit.DoesNotExist:
        return HttpResponseRedirect('/activities/')

I was also trying with: ” except act_edit.DoesNotExist: ”
but the error persists “Activity matching query does not exist.”
Any idea?

Thanks!

You need to move the statement that can cause the exception in the body of the try: clause.

The syntax is “try: something catch stuff:” your something is above the try:

act_edit= Activity.objects.filter(campaing=1).get(pk=edit)
try:

Should be

try:
   act_edit = Activity.objects.filter(campaing=1).get(pk=edit)
