与相同两个类别的多个关系 - django

Question

我有两个类，它们之间有两个与许多关系。由于相邻的表也必须具有其他属性，因此我明确定义了它们。但是我遇到了一个错误，说我需要更改相关名称。不确定在哪里做。任何帮助都非常感谢。

这是我的型号。py代码：

class Client(models.Model):
    first_name = models.CharField(max_length=255)
    last_name = models.CharField(max_length=255)
    email = models.CharField(max_length=255)
    password = models.CharField(max_length=255)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    objects = UserManager()
    def __repr__(self):
        return "<User object: {} {} {} {}>".format(self.first_name, 
self.last_name, self.email, self.password)
class Therapist(models.Model):
    name = models.CharField(max_length=255)
    reviews = models.ManyToManyField(Client, through="Review")
    appts = models.ManyToManyField(Client, through="Appointment")
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    objects = UserManager()
    def __repr__(self):
        return "<Book object: {}>".format(self.title)

class Review(models.Model):
    reviewer = models.ForeignKey(Client, on_delete=models.CASCADE)
    therapist_reviewed = models.ForeignKey(Therapist, 
on_delete=models.CASCADE)
    rating = models.IntegerField()
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    content = models.TextField()
    def __repr__(self):
        return "<Review object: {} {}>".format(self.book_reviewed, 
self.reviewer)
class Appointment(models.Model):
    booked_therapist = models.ForeignKey(Therapist, 
on_delete=models.CASCADE)
    booked_client = models.ForeignKey(Client, on_delete=models.CASCADE)
    date = models.DateTimeField()
    massage = models.CharField(max_length=255)

Answer 1

class Therapist(models.Model):
    name = models.CharField(max_length=255)
    reviews = models.ManyToManyField(Client, related_name='therapist_reviews', through="Review")
    appts = models.ManyToManyField(Client, related_name='therapist_appts', through="Appointment")
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    objects = UserManager()
    def __repr__(self):
        return "<Book object: {}>".format(self.title)

如果您不为many_to_many字段分配RESSID_NAME，则将默认相关的相关设置为model_lower_case_set，但是当您具有两个与同一模型相关的many_to_many字段时，两个归档的默认值相关_name与model_lower_case_set相同使用related_name查询QuerySet时的冲突。
