Django - 创建超级用户

Question

我创建了模型用户 我添加了这两行“ is_superuser=models.BooleanField(default=False) is_staff=models.BooleanField(default=False)" 只是为了绕过问题并通过模型创建一个超级用户而不是默认用户但这不能解决我的问题我需要创建一个默认的 django super uesr

from django.db import models
from django.contrib.auth.models import AbstractUser

class User(AbstractUser):
    first_name= models.CharField(max_length=30)
    last_name= models.CharField(max_length=30)
    cin     = models.IntegerField()
    username= models.CharField(max_length=30,unique=True)   
    password= models.CharField(max_length=30)   
    codeQR  = models.CharField(max_length=30)
    poste   = models.CharField(max_length=30)
    image   = models.CharField(max_length=30)
    email   = models.EmailField()
    telephone= models.IntegerField()
    is_superuser=models.BooleanField(default=False)
    is_staff=models.BooleanField(default=False)

    USERNAME_FIELD = 'username'
    REQUIRED_FIELDS = []


class pointage(models.Model):
    entre   = models.CharField(max_length=30)
    sortie  = models.CharField(max_length=30)
    retard  = models.CharField(max_length=30)
    absance = models.CharField(max_length=30)   
    user    = models.ManyToManyField(User)


class salaire(models.Model):
    mois      = models.IntegerField()
    heurs_base= models.FloatField()
    heurs_sup = models.FloatField()
    primes    = models.FloatField()  
    total     = models.FloatField()   
    user    = models.ManyToManyField(User)

但我得到以下错误

PS C:\py\pointage> py manage.py createsuperuser
Username: a
Password: 
Password (again):
Error: Your passwords didn't match.
Password: 
Password (again):
The password is too similar to the username.
This password is too short. It must contain at least 8 characters.
This password is too common.
Bypass password validation and create user anyway? [y/N]: y

The above exception was the direct cause of the following exception:

我不知道为什么会出现这个错误或如何解决它，你能帮帮我吗！

Answer 1

发生这种情况是因为您使用 AbstractUser覆盖了默认的 User 模型。

这就是你要做的：

1. 创建一个具有OneToOneRelationship 和User 模型的UserProfile 模型。
2. 将之前指向User模型的所有模型更改为指向UserProfile模型。

现在，当您创建超级用户时，您不会遇到任何问题。

编辑：

您可以参考这个post，它展示了如何扩展默认的User 模型。
