[Django]-Filter Django database for field containing any value in an array

✅

Make successive calls to filter, like so:

queryset = Profile.objects.all()
strings = ['keith', 's', 'thompson']
for string in strings:
    queryset = queryset.filter(full_name__icontains=string)

Alternatively you can & together a bunch of Q objects:

condition = Q(full_name__icontains=s[0])
for string in strings[1:]:
    condition &= Q(full_name__icontains=string)
queryset = Profile.objects.filter(condition)

A more cryptic way of writing this, avoiding the explicit loop:

import operator
# ...
condition = reduce(operator.and_, [Q(full_name__icontains=s) for s in strings])
queryset = Profile.objects.filter(condition)

Even shorter using the operator functions and_ or or_ to combine the list of Q() conditions

from operator import and_, or_
li = ['keith', 's', 'thompson']

Items that match all the strings (and_)

Profile.objects.filter(reduce(and_, [Q(full_name__icontains=q) for q in li]))

Items that match any of the strings (or_)

Profile.objects.filter(reduce(or_, [Q(full_name__icontains=q) for q in li]))

The Q() function implements __or__() and __and__() to join two Q() objects together, so they can be called using the corresponding operator functions.

something along these lines:


array = ['keith', 's', 'thomson']
regex = '^.*(%s).*$' % '|'.join(array)
Profile.objects.filter(full_name__iregex=regex)

EDIT: this is wrong, the OP wants names which contain all strings simultaneously.
