现在我们有了有效的自定义用户模型，我们可以添加每个网站需要的功能：注册、登录和注销用户的能力。 Django 提供了我们登录和注销所需的一切，但我们需要创建自己的表单来注册新用户。我们还将构建基本主页，其中包含指向所有三个功能的链接，因此我们不必每次都手动输入 URL。

管理页面

from django import forms
from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from .models import CustomUser
class CustomUserCreationForm(UserCreationForm):
class Meta(UserCreationForm):
model = CustomUser
fields = ('username', 'email', 'age',) # new
class CustomUserChangeForm(UserChangeForm):
class Meta:
model = CustomUser
fields = ('username', 'email', 'age',) # new
注册用户testuser后登录
访问http://127.0.0.1:8000/admin会提示没有权限。
结论
到目前为止，我们的 Newspaper 应用程序有一个自定义用户模型和工作注册、登录和注销页面。但是您可能已经注意到我们的网站看起来不太好。在下一章中，我们将为样式添加 Bootstrap 并创建专用的页面应用程序。
