It doesn't work that way. ORM translates you queries to SQL and the DB is responsible for filtering. It is not possible to translate arbitrary python function to SQL or pass it to DB engine. So you have to formulate you query using .filter syntax or raw SQL.
Another possibility is to denormalize data: add 'complete' field to the model and recalculate it on save (or whenever it make sense). This is often a good solution and it is better than complex queries in terms of performance. On 16 янв, 19:16, rmschne <[email protected]> wrote: > Thanks.
