Error: 404 Page Not Found. After trying to update a form

Question

I currently have a settings model for my Django app which saves a set of settings for the rest of the program to read from.

I have tried to create a way to update these settings on the app, as per the below code.

When the update button is clicked, however, the app returns a page not found error instead of updating the database. Does anyone know what could be causing it because I cannot seem to find any errors in the code?

Views.py:

def viewSettings(request,  settings_pk):
    setting = get_object_or_404(SettingsClass, pk=settings_pk)
    if request.method == 'GET':
        form = SettingUpdateForm(instance=setting)
        return render(request, 'main/viewSettings.html', {'setting': setting, 'form':form})
    else:
        try:
            form =  SettingUpdateForm(request.POST, instance=setting)
            form.save()
            return redirect('settingsHome')
        except ValueError:
            return render(request, 'main/viewSettings.html', {'setting': setting, 'form':form, 'error':'Bad info'})

as you are redirecting the form submit to a wrong view and not the view where you are updating the settings object.
