django icontains with __in lookup

Question

So I want to find any kind of matching given some fields, so for example, this is what I would like to do:

possible_merchants = [\"amazon\", \"web\", \"servi         


        

Answer 1

You can create querysets with the Q constructor and combine them with the | operator to get their union:

from django.db.models import Q

def companies_matching(merchants):
    """
    Return a queryset for companies whose names contain case-insensitive
    matches for any of the `merchants`.
    """
    q = Q()
    for merchant in merchants:
        q |= Q(name__icontains = merchant)
    return Companies.objects.filter(q)

(And similarly with iexact instead of icontains.)
