使用Django中的自定义字段扩展用户模型

python manage.py startapp user_extension

# user_extension/models.py
from django.db import models
from django.contrib.auth.models import User

class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    phone = models.CharField(max_length=100)
    address = models.CharField(max_length=100)

    def __str__(self):
        return self.user.username

INSTALLED_APPS = [
    # ...
    'user_extension',
]

python manage.py makemigrations
python manage.py migrate

# user_extension/views.py
from django.shortcuts import render
from .models import UserProfile

def user_profile(request, user_id):
    user_profile = UserProfile.objects.get(user_id=user_id)
    return render(request, 'user_extension/user_profile.html', {'user_profile': user_profile})

<!-- user_extension/templates/user_extension/user_profile.html -->
<h1>{{ user_profile.user.username }}</h1>
<p>Phone: {{ user_profile.phone }}</p>
<p>Address: {{ user_profile.address }}</p>
