[Fixed]-Common practice to query from django models

To my best knowledge it is perfectly fine to make the queries directly at the appropriate places.

I do not see how your proposed abstraction adds any value. The exception would be if you modify the queried data somehow before returning it.

If you are using the queries in multiple places, it’s probably a good idea. In the future if a query changes or needs permissions applied, you can just change the method. But I wouldn’t bother creating the methods until you are actually writing duplicate queries.
