I recently asked how to solve a simple SQL query. Turns out that there are many solutions.
After some benchmarking i think this is the best one:
SELECT DISTINCT Camera.*
FROM Camera c
INNER JOIN cameras_features fc1 ON c.id = fc1.camera_id AND fc1.feature_id = 1
INNER JOIN cameras_features fc2 ON c.id = fc2.camera_id AND fc2.feature_id = 2
Now, I’ve not clue how to perform this query with Django ORM.
If you need exactly this query you can execute this in django like raw sql. Here you can find about raw sql in django.
It`s good to put your sql code into a custom manager. An example with manager and raw sql can be found here
