Almost there.. members.filter(**{‘string__contains’: ‘search_string’}) To understand what it’s doing, google around : ) Understanding kwargs in Python ** expands dictionary key/value pairs to keyword argument – value pairs. To adapt your example to the solution: variable_column = ‘name’ search_type=”contains” filter = variable_column + ‘__’ + search_type info=members.filter(**{ filter: search_string })
I finally found the solution: mypath = customerbulk.objects.get(pk=1).fileup.path o = open(mypath,’rU’) mydata = csv.reader(o)

Yes, I think you want make = Make.objects.get(pk=1) make.make_content_set.filter(published=True) or maybe make_ids = MakeContent.objects.filter(published=True).values_list(‘make_id’, flat=True) makes = Make.objects.filter(id__in=make_ids)
