django auth模块帮你实现完整的用户体系
Django的auth模块提供了一个完整的用户管理系统,包括用户认证、用户组、权限等功能。以下是使用Django auth模块的一些基本方法:
- 用户认证:
from django.contrib.auth import authenticate
def login_view(request):
username = request.POST['username']
password = request.POST['password']
user = authenticate(request, username=username, password=password)
if user is not None:
login(request, user)
# Redirect to a success page.
else:
# Return an 'invalid login' error message.
- 创建新用户:
from django.contrib.auth.models import User
def register_view(request):
username = request.POST['username']
password = request.POST['password']
user = User.objects.create_user(username=username, password=password)
user.save()
# Log the user in and then redirect to a success page.
- 检查用户权限:
from django.contrib.auth.decorators import login_required
@login_required
def my_view(request):
# Code here assumes user is logged in.
- 创建和分配权限:
from django.contrib.auth.models import Permission
# 给特定的用户添加权限
user = User.objects.get(username='john')
add_permission = Permission.objects.get(name='Can add log entry')
user.user_permissions.add(add_permission)
# 给组内的所有用户添加权限
group = Group.objects.get(name='Staff')
add_permission = Permission.objects.get(name='Can add log entry')
group.permissions.add(add_permission)
- 创建和管理用户组:
from django.contrib.auth.models import Group
# 创建一个新的用户组
group = Group.objects.create(name='Shopkeepers')
# 将用户添加到组
user = User.objects.get(username='john')
group.user_set.add(user)
以上代码提供了使用Django auth模块的基本示例。在实际应用中,你需要根据具体需求对这些方法进行适当的调整和扩展。
