如何在Django中使用注释获取对象不同字段的总和？

如何解决如何在Django中使用注释获取对象不同字段的总和？

我有三个这样的模型：

class Corredor (models.Model):
    dorsal=models.IntegerField(primary_key=True)
    tipo=models.CharField(max_length=50)
    nombre=models.CharField(max_length=50)
    f_nacimiento=models.DateField(default=1/1/1975)
    nacimiento=models.IntegerField()
    categoria=models.CharField(max_length=50)
    pais=models.CharField(max_length=50)
    equipo=models.CharField(max_length=50)
    nombre_equipo=models.CharField(max_length=50)
    lid=models.BooleanField()
    gre=models.BooleanField()
    jor=models.BooleanField()
    giro=models.BooleanField()
    tour=models.BooleanField()
    vuelta=models.BooleanField()
    abandono_giro=models.IntegerField(default=0)
    etapa_aban_giro=models.IntegerField(default=0)
    abandono_tour=models.IntegerField(default=0)
    etapa_aban_tour=models.IntegerField(default=0)
    abandono_vuelta=models.IntegerField(default=0)
    etapa_aban_vuelta=models.IntegerField(default=0)

    class Meta:
        ordering=['nombre']

    def __str__(self):
        return self.nombre

class Equipo (models.Model):
    alias=models.CharField(max_length=50,primary_key=True)
    lid1=models.ForeignKey(Corredor,limit_choices_to={'lid':True,'giro':True,'tipo': "Rider"},related_name="lid1",on_delete=models.CASCADE)
    lid2=models.ForeignKey(Corredor,related_name="lid2",on_delete=models.CASCADE)

    jlg_sup=models.ForeignKey(Corredor,related_name="jlg_sup",on_delete=models.CASCADE)
    ganador_e1=models.ForeignKey(Corredor,limit_choices_to={'giro':True,related_name="ganador_e1",on_delete=models.CASCADE)
    ganador_e2=models.ForeignKey(Corredor,related_name="ganador_e2",on_delete=models.CASCADE)
    ganador_e3=models.ForeignKey(Corredor,related_name="ganador_e3",on_delete=models.CASCADE)
    ganador_e4=models.ForeignKey(Corredor,related_name="ganador_e4",on_delete=models.CASCADE)
    ganador_e5=models.ForeignKey(Corredor,related_name="ganador_e5",on_delete=models.CASCADE)
    ganador_e6=models.ForeignKey(Corredor,related_name="ganador_e6",on_delete=models.CASCADE)
    ganador_e7=models.ForeignKey(Corredor,related_name="ganador_e7",on_delete=models.CASCADE)
    ganador_e8=models.ForeignKey(Corredor,related_name="ganador_e8",on_delete=models.CASCADE)
    ganador_e9=models.ForeignKey(Corredor,related_name="ganador_e9",on_delete=models.CASCADE)
    ganador_e10=models.ForeignKey(Corredor,related_name="ganador_e10",on_delete=models.CASCADE)
    ganador_e11=models.ForeignKey(Corredor,related_name="ganador_e11",on_delete=models.CASCADE)
    ganador_e12=models.ForeignKey(Corredor,related_name="ganador_e12",on_delete=models.CASCADE)
    ganador_e13=models.ForeignKey(Corredor,related_name="ganador_e13",on_delete=models.CASCADE)
    ganador_e14=models.ForeignKey(Corredor,related_name="ganador_e14",on_delete=models.CASCADE)
    ganador_e15=models.ForeignKey(Corredor,related_name="ganador_e15",on_delete=models.CASCADE)

    ganador_e21=models.ForeignKey(Corredor,related_name="ganador_e21",on_delete=models.CASCADE)
    ganador_tour=models.ForeignKey(Corredor,related_name="maillot_amarillo",on_delete=models.CASCADE)
    segundo_tour=models.ForeignKey(Corredor,related_name="segundo",on_delete=models.CASCADE)
    tercero_tour=models.ForeignKey(Corredor,related_name="tercero",on_delete=models.CASCADE)
    cuarto_tour=models.ForeignKey(Corredor,related_name="cuarto",on_delete=models.CASCADE)
    quinto_tour=models.ForeignKey(Corredor,related_name="quinto",on_delete=models.CASCADE)
    sexto_tour=models.ForeignKey(Corredor,related_name="sexto",on_delete=models.CASCADE)
    mv=models.ForeignKey(Corredor,related_name="maillot_verde",on_delete=models.CASCADE)
    mpr=models.ForeignKey(Corredor,related_name="maillot_puntos_rojos",on_delete=models.CASCADE)
    mb=models.ForeignKey(Corredor,'nacimiento__gte': 1996},related_name="maillot_blanco",on_delete=models.CASCADE)
    sc=models.ForeignKey(Corredor,related_name="supercombativo",on_delete=models.CASCADE)
    me=models.ForeignKey(Corredor,'tipo': "Team"},related_name="mejor_equipo",on_delete=models.CASCADE)
    owner=models.ForeignKey(User,on_delete=models.CASCADE)
    created=models.DateTimeField(auto_Now_add=True)

    def __str__(self):
        return self.alias


class Puntuacion (models.Model):
    competicion=models.CharField(max_length=50)
    temporada=models.IntegerField()
    etapa=models.IntegerField()
    modalidad=models.CharField(max_length=50)
    dorsal=models.ForeignKey(Corredor,blank=True,null=True,related_name="puntos",on_delete=models.CASCADE)
    categoria=models.CharField(max_length=50)
    descripcion=models.CharField(max_length=150)
    puntos=models.IntegerField()

    def __str__(self):
        return self.categoria

在 Puntuacion 中，背侧可以有不同类别的 puntos，也可能没有任何 puntos。 目标是，在 Equipo 模型中，对于每个 Alias，都有不同领域（lid1、lid2、lid2、........gre1、gre2、. ....).

我是 Django 新手，我认为使用 annotate 是一种选择，但我不知道如何进行查询。

感谢任何能帮助我的人。
