一旦用户登录，如何将用户重定向到他们尝试访问的页面？ （Django）

Question

So currently I'm using @login_required to block certain pages from users and redirect them, telling them they need to log in. but what I can't understand is how do I "let them" go to the page they were trying to go to once they log in. Currently I'm just using a typical render_to_response('with a certain view') but what if i want that response to be anywhere where they were trying to access. How do i code that?

Answer 1

您可以将url参数传递回登录页面，并在用户成功完成登录后使用该参数指导用户。

Answer 2

The @login_required will generally pass you back the redirect_field_name (default is "next") for example: /accounts/login/?next=/polls/3/. So in your login view after authenticating and logging in the user you can do something like

response = HttpResponseRedirect(next)
# Do whatever else you need to do here with the response object
return response

See the docs at https://docs.djangoproject.com/en/1.3/topics/auth/#the-login-required-decorator

Answer 3

from the login requiered decorator docs it says:

By default, the path that the user should be redirected to upon successful authentication is stored in a query string parameter called "next".

and usually when the login is done it take to the "next" url

Here's what django.contrib.auth.views.login does:

If called via GET, it displays a login form that POSTs to the same URL. More on this in a bit.
If called via POST , it tries to log the user in. If login is successful, the view redirects to the URL specified in next . If next isn't provided, it redirects to settings.LOGIN_REDIRECT_URL (which defaults to /accounts/profile/). If login isn't successful, it redisplays the login form.
