问题描述
我需要一些帮助来在我的三个模型中进行查询。第一个是Cyclist，有编号（pk）、姓名、生日等字段。第二个模型是带有id（pk）、分类类型、阶段编号、编号（外键）和分数的分类。我需要做的第一个查询是为每个骑自行车的人获取每个阶段编号的总分。
我的选择是：
puntos=Corredor.objects.values('dorsal','etapa').aggregate(total_puntos=Sum('puntos')
在那之后，我有另一个团队模型。团队是由客户选择的一组自行车手。我想为每个团队获得组成该团队的自行车手的总积分，但在这种情况下，我不知道如何在新查询中使用查询 puntos 进行注释。也许：
team_points=Equipo.objects.annotate(F(Sum(lid__dorsal__puntos))+(Sum(lid2__dorsal__puntos))+...........)))
预先感谢您的帮助。
