Question

how can i check if i have an empty column in my queryset?

this is my code :

        mastercard_percent = ClientPaymentOption.objects.filter(name='MasterCard', client=client).values_list('itemcharged',flat=True)
        if mastercard_percent == [None]:
            print 'empty'
        print mastercard_percent

and i got only this:

[None]

i try also in my code to become:

            if mastercard_percent == [None]:
                print 'empty'
            print mastercard_percent

but it also print :

[None]

thanks in advance…

You have to check the values of the column

like if not mastercard_percent[0]: print 'empty'
