This is a UserMapper model in django.
I want to write a query such that:

Get all the user_id whose foo_id = 2 and type=0 and all the result of user_id = 6;
Say;

select * from table where user_id = 6 and (foo_id=2 and type=6) // Such sort of query

How can I do in django query set..

Answer 1

If you mean user_id=6 and type=6 and food_id=2, then just use:

UserMapper.objects.filter(user_id=6, type=6, food_id=2)

if you mean (user_id=6) or (type=6 and food_id=2), you can use the Q object :

from django.db.models import Q
UserMapper.objects.filter(Q(user_id=6) | Q(type=6, food_id=2))

See more about Q object here: http://docs.djangoproject.com/en/dev/topics/db/queries/#complex-lookups-with-q-objects
