Question

我想用'Profile'模型扩展我的'User'模型。为方便起见，我创建了以下模型。我想让每个新的“用户”模型自动创建链接的“配置文件”模型。基于对互联网上的stackoverflow /研究的一些评论（simpleisbetterthancomplex），我提出了以下解决方案：

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


# Create your models here.
class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='profile')

    #Pushup related stats
    total_pushups = models.IntegerField(default=0)
    best_consecutive = models.IntegerField(default=0)
    week_streak = models.IntegerField(default=0)
    save = models.IntegerField(default=000)

    @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()

然而，每次我运行它（无论是通过单元测试还是'创建超级用户' - 我还没有竞争，我正在练习TDD）我收到以下错误：

TypeError: 'int' object is not callable

有谁在这里知道我做错了什么？

编辑：我已经包含了“创建超级用户”命令后显示的错误消息的回溯

Answer 1

您已经定义了一个名为save的字段，该字段隐藏了实际的save方法。将其重命名为其他内容。

（与你的问题无关，但你当然不应该有两个接收器。我不明白为什么你需要第二个接收器，但即使你确实需要这个逻辑，你应该把它放进去与第一个。）

Django OneToOneField post_save无法调用int对象
