Does Django support JOIN?

问题

Does Django ORM support join like INNER JOIN, LEFT JOIN, RIGHT JOIN AND OUTER JOIN?

I read the document, and did not found one.

For example how can I do this?

SELECT * 
FROM auth_user_groups
JOIN test_groups ON auth_user_groups.group_id=test_groups.group_id
WHERE test_id='1'
AND user_id='2'
LIMIT 1

test_group is a Many to many table, without any model class.

No. Use relational fields and appropriately-crafted queries to perform joins instead.
