DJANGO - profile.user 的反向访问器与同一字段的反向访问器冲突？

Question

我收到以下错误：

    dsapi.Profile.user: (fields.E304) Reverse accessor for 'Profile.user' clashes with reverse accessor for 'Profile.user'.

        HINT: Add or change a related_name argument to the definition for 'Profile.user' or 'Profile.user'.

dsapi.Profile.user: (fields.E305) Reverse query name for 'Profile.user' clashes with reverse query name for 'Profile.user'.

我的所有研究都表明可以related_name为每个问题创建一个。但就我而言，它告诉我反向访问器本身有问题。这里有人有什么想法吗？下面是我的 models.py 文件中有问题的代码。

import uuid

from django.db import models

from django.contrib.auth.models import User

from django.db.models.signals import post_save

from django.dispatch import receiver

class DsapiModel(models.Model):

    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)

    created_at = models.DateTimeField(auto_now_add=True, editable=False)

    updated_at = models.DateTimeField(auto_now=True, editable=False)

    class Meta:

        abstract = True

class Profile(DsapiModel):

    """

    Extend User model using one-to-one link

    Save a query using users = User.objects.all().select_related('profile')

    """

    user = models.OneToOneField(User, on_delete=models.CASCADE)

    favorite_sites = models.ManyToManyField(Site)

    def __str__(self):

        return self.user.username

@receiver(post_save, sender=User)

def create_user_profile(sender, instance, created, **kwargs):

    if created:

        Profile.objects.create(user=instance)

@receiver(post_save, sender=User)

def save_user_profile(sender, instance, **kwargs):

    instance.profile.save()

该错误表明Profile <-> User您的项目中存在多个关系。任意，它们之间可以有尽可能多的关系，但是，它们related_name必须是不同的。这是一篇 SO 帖子，可以帮助您理解related_name在 Django 中有什么related_name用？
