How can I chain Django's "in" and "iexact" queryset field lookups?

I have a list of names, e.g.:

name_list = ['Alpha', 'bEtA', 'omegA']

Currently I have the following queryset:

MyModel.objects.filter(name__in=name_list)

I would like to be able to filter the names in a case-insensitive fashion. My first thought was to use the iexact field lookup but it doesn't seem to work with in. How can I use the iexact with the in field lookup for my queryset? Or is there an alternate way to perform this query?

Solution

  • Here's my solution, which uses Q objects instead:

    name_list = ['Alpha', 'bEtA', 'omegA']
q_list = map(lambda n: Q(name__iexact=n), name_list)
q_list = reduce(lambda a, b: a | b, q_list)
MyModel.objects.filter(q_list)
