Writing a tuple search with Django ORM
I'm trying to write a search based on tuples with the Django ORM syntax. The final sql statement should look something like: SELECT * FROM mytable WHERE (field_a,field_b) IN ((1,2),(3,4)); I know I can achieve this in django using the extra keyword: MyModel.objects.extra( where=["(field_a, field_b) IN %s"], params=[((1,2),(3,4))] ) but the "extra" keyword will be deprecated at some point in django so I'd like a pure ORM/django solution. Searching the web, I found https://code.djangoproject.com/ticket/33015 and the comment from Simon Charette, something like the snippet below could be OK, but I can't get it to work. from django.db.models import Func, lookups class ExpressionTuple(Func): template = '(%(expressions)s)' arg_joiner = "," MyModel.objects.filter(lookups.In( ExpressionTuple('field_a', 'field_b'), ((1,2),(3,4)), )) I'm using Django 3.2 but I don't expect Django 4.x to do a big difference here. My db backend is posgresql in case it matters. -

One for sender message and another for recipient message. recipient_message = Message(user=to_user, sender=from_user, recipient=from_user, body=body, is_read=True) Then for the recipient_message I'm not clear why the recipient field is set to from_user instead of to_user??

CKEDITOR PillowBackend Django disable thumbnail creation
