How to dynamically provide lookup field name in Django query? [duplicate]

Answer 1

I would prefer to use the Q object for something like this.

from django.db.models import Q

keyword = 'keyword'
fields = ['foo', 'bar', 'baz']

Qr = None
for field in fields:
    q = Q(**{"%s__contains" % field: keyword })
    if Qr:
        Qr = Qr | q # or & for filtering
    else:
        Qr = q

# this you can now combine with other filters, exclude etc.    
results = MyModel.objects.filter(Qr)
