Re: Search by entering to value in JSONField PostgreSQL

Hi, Did you try SomeModel.objects.filter(data__name__contains="ar") If you want to union the results from both fields you can use a Q object: https://docs.djangoproject.com/en/2.0/topics/db/queries/#complex-lookups-with-q-objects And that would look something like: complex_query =
