Django Implements user login access Restrictions @login_required

In the process of website development, we often encounter such requirements: the user login system to access certain pages

If the user does not log in and the direct access will jump to the landing screen, and not access to other pages.

When the user completes the login in the login interface of the jump, automatic access jumps to the previously visited address

To implement such a requirement is simple:

1. @login_required with Django's own decorator.

2. Add @login_required in front of the corresponding view method

3. And configure the Login_url parameter in settings.py

4. Change the form action parameter in LOGIN.HTLM

#views. py

From djanco.contrib.auth.decorators import login_requiredfrom django.shortcuts import Render_to_responsefrom Django.http Import HttpResponse @login_requireddef myview (Request): Return Render_to_response (' index.html ')

#settings. py

.... Login_url = '/accounts/login/' #这个路径需要根据你网站的实际登陆地址来设置 ....

If you want to use Django's default login interface, you can do so by configuring it in urls.py

#urls. py

From django.conf.urls import urlfrom django.contrib import adminfrom app01 import viewsurlpatterns = [url (r ' ^admin/'), admin.site.urls), url (r ' ^, views.index), url (r ' ^accounts/login/, views.acc_login), url (r ' ^logout/, Views.acc_logo UT), url (r ' ^host/, Views.host, name= ' host '), URL (r ' ^asset/, views.asset,name= ' asset '), url (r ' ^audit/, Views.audit , Name= ' audit '),]

#login. html

<div class= "Container" >  <form class= "Form-signin"  action= "/accounts/login/"  method= "POST" >{% csrf_token %} <!--Csrf_token: Generate token-->
