Django - 重定向与上下文

问题描述

我有一个注册页面，它接受用户的用户名和密码并将其保存在数据库中。如果用户注册成功，我想将其重定向到登录页面，其值指示注册成功。

重定向的预期输出页面：

您已成功注册。

在

用户名：---

密码：---

所以，我正在从注册页面重定向到登录页面，但是我想传递一个值，显示用户已经来

$ b

如何执行此操作？

解决方案

使用在第一个视图中添加消息，在第二个中显示它。

或者简单地在会话中放入一个项目，然后再次弹出：

  request.session ['signup'] = True 
 retu rn redirect（'wherever'）
  

...

  signup = request.session.pop（'signup'，False）
如果注册：
 ...做某事... 
  

I have a Sign Up page which takes a user's username and password and saves it in the database. If the user is successfully signed up, I want to redirect him to a 'Sign In' page, with a value denoting that Signup was successful.

Expected output on the redirected page:

You have been successfully signed up.

Sign In

Username: ---

Password: ---

So, I am redirecting from the signup to the signin page, but I want to pass a value showing that the user has come from the Signup page and is successfully signed up.

How do I perform this?

解决方案

Use the messages framework to add a message in the first view and display it in the second one.

Or simply put an item in the session, and pop it out again:

request.session['signup'] = True
return redirect('wherever')

...

signup = request.session.pop('signup', False)
if signup:
    ... do something ...
