Django OneToOneField post_save無法調用int對象

Question

我想用'Profile'模型擴展'User'模型。爲了促進這一點，我創建了以下模型。我想用每個新的「用戶」模型自動創建鏈接的「配置文件」模型。基於互聯網（simpleisbetterthancomplex）我想出了以下解決方案上計算器/研究的一些評論：

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，我每次運行這個（無論是通過單元測試或者「創建超級用戶」 - 我沒有搶答但我正在練習TDD）我得到以下錯誤：

TypeError: 'int' object is not callable 

有沒有人知道我在做什麼錯？

編輯：我已經提供了是「創建超級用戶」命令後顯示

Answer 1

您已經定義了一個名爲save場，這是隱藏實際save方法。將它重命名爲其他內容。我不明白你爲什麼需要第二個接收器，但即使你確實需要這個邏輯，你也應該把它放在這裏。在第一個。）

Answer 2

保持created_user_profile和save_user_profileProfile模型的外面都錯誤信息的回溯。 Unindent吧。

class UserProfile(models.Model): 
    user = models.OneToOneField(User, on_delete=models.CASCADE,default=1) 
    . . . . . 
    . . . . .

@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() 

也試着改變save場

user_save = models.IntegerField(default=0)
