相关疑难解决方法(0)

我试图计算一个玩家每周玩的次数如下:

player.game_objects.extra(
    select={'week': 'WEEK(`games_game`.`date`)'}
).aggregate(count=Count('week'))

但是Django抱怨说

FieldError: Cannot resolve keyword 'week' into field. Choices are: <lists model fields>

我可以在这样的原始SQL中做到这一点

SELECT WEEK(date) as week, COUNT(WEEK(date)) as count FROM games_game
WHERE player_id = 3
GROUP BY week

如果没有在Django中执行原始SQL,有没有一个好方法呢？
