django ORM 聚合计数

Question

我想获取用户的预定试驾次数和已完成试驾次数

obj= TestRide.objects.filter(feature=feature_obj).aggregate(
    scheduled_count=(
        Count('status', filter=Q(status='Scheduled'))
    ),
    completed_count=(
        Count('status', filter=Q(status='Completed'))
    ),
)

我在 schedule_count 和 completed_count 中获得了相同的计数值我认为我的过滤器不起作用，谁能帮帮我 谢谢

你能试试这个吗：

test = TestRide.objects
test_scheduled_count = test.filter(feature=feature_obj,status='Scheduled').aggregate(
    scheduled_count=Count('status')).get('scheduled_count')

test_completed_count = test.filter(feature=feature_obj,status='Completed').aggregate(
    completed_count=Count('status')).get('completed_count')
