Unfortunatley, there are no __iin
field lookup. But there is a iregex
that might be useful, like so:
result = Name.objects.filter(name__iregex=r'(name1|name2|name3)')
or even:
a = ['name1', 'name2', 'name3']
result = Name.objects.filter(name__iregex=r'(' + '|'.join(a) + ')')
Note that if a can contain characters that are special in a regex, you need to escape them properly.
NEWS: In Django 1.7+ it is possible to create your own lookups, so you can actually use filter(name__iin=['name1', 'name2', 'name3'])
after proper initialization. See documentation reference for details.
