使用Django框架完成用户的增删改查操作

以下是一个简单的Django框架示例，展示了如何实现用户的增删改查操作：

首先，确保你已经安装了Django。

1. 创建一个新的Django项目和应用：

django-admin startproject myproject
cd myproject
python manage.py startapp users

2. 编辑 users/models.py 来定义用户模型：

from django.db import models
from django.contrib.auth.models import AbstractUser
 
class User(AbstractUser):
    is_active = models.BooleanField(default=True)

3. 更新 settings.py 来使用自定义的用户模型：

# settings.py
 
AUTH_USER_MODEL = 'users.User'

4. 创建数据库迁移：

python manage.py makemigrations
python manage.py migrate

5. 在 users/views.py 中编写视图函数来处理CRUD操作：

from django.shortcuts import render, redirect
from django.contrib import messages
from django.contrib.auth.models import User
from django.contrib.auth import update_session_auth_hash
 
# 创建用户
def create_user(request):
    if request.method == 'POST':
        username = request.POST['username']
        password = request.POST['password']
        user = User.objects.create_user(username=username, password=password)
        user.save()
        messages.success(request, 'User created successfully')
        return redirect('users:list_users')
 
    return render(request, 'users/create_user.html')
 
# 删除用户
def delete_user(request, pk):
    user = User.objects.get(pk=pk)
    user.delete()
    messages.success(request, 'User deleted successfully')
    return redirect('users:list_users')
 
# 更新用户
def update_user(request, pk):
    user = User.objects.get(pk=pk)
    if request.method == 'POST':
        username = request.POST['username']
        password = request.POST['password']
        user.username = username
        user.set_password(password)
        user.save()
        messages.success(request, 'User updated successfully')
        return redirect('users:list_use
