如何在 django 中的用户模型中将“移动”字段添加到默认的 auth_user 表？

Question

I want to add Mobile filed to be saved to auth_user table when i register.

models.py

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

class UserRegModel(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    mobile = models.CharField(max_length=100)

forms.py

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm

class UserRegisterForm(UserCreationForm):
    mobile = forms.CharField(max_length=15)

    class Meta:
        model = User
        fields = ['username','email','mobile','password1','password2']

Answer 1

If you want to store all user data together, you should substitute a user model instead of creating a OneToOne relationship. Judging by the current code you will get 2 tables - one for standard Django user and one connected to it with mobile data.

Here you can read more about substituting a user and the difference between these 2 approaches:

Extending the User model with custom fields in Django

Or directly in the documentation:
