Title
Body
I'm trying to do a django query, but with the possibility of several different WHERE parameters. So I was thinking of doing something like: querystring = "subcat__id__in=[1,3,5]" Listing.objects.filter(querystring) Here Listing is defined in my model, and it contains the Many-To-Many field subcat . However, that raises a ValueError because filter doesn't accept a string as its argument. Is there a way in Python to have a string evaluated as just its contents rather than as a string? Something like a print statement that prints the value of the string inline rather than to the standard output. By the way, the reason I don't just do querystring = [1,3,5] Listing.objects.filter(subcat__id__in=querystring) is that I'm not always filtering for subcat__id , sometimes it's one or several other parameters, and I'd rather not have to write out a bunch of separate queries controlled by if statements. Any advice is much appreciated.
