Django filter with OR condition using dict argument

Question

I have a function on my Django app where I perform some Queryset actions and set it\'s result to Memcache. Since it is a function it has to be of general usage. So in order

Answer 1

You can restructure your dictionary into a list of single key-value dictionaries and use unpacking on each dict inside the Q expression like so:

from functools import reduce
import operator

from django.db.models import Q

# your dict is my_filter
q = model.objects.filter(reduce(operator.or_, 
                                (Q(**d) for d in [dict([i]) for i in my_filter.items()])))

reduce on or_ joins the Q expressions on an OR.

You could also use a generator expression where you have the list of dicts:

q = model.objects.filter(reduce(operator.or_, 
                                (Q(**d) for d in (dict([i]) for i in my_filter.items()))))
