Django RedirectView和reverse（）不一起工作？ [英] Django RedirectView and reverse() doesn't work together?

问题描述

我有这个奇怪的问题。

当我这样做：

from django.core.urlresolvers import reverse
reverse('account-reco-about-you')
# returns '/accounts/recommendations/about-you/'

但是当我这样做：

# Doesn't Work
recommendations = login_required(RedirectView.as_view(url=reverse('account-reco-about-you')))

# Work
recommendations = login_required(RedirectView.as_view(url='/accounts/recommendations/about-you'))

错误信息如果不相关，我得到。它说我的最后一个视图是没有找到，那是在那里。任何解释？同时，我会用非反向风格做。

Error message I get if unrelated. It says my last view is not found, which is there. Any explanation? Meantime, i'll make do with the non-reverse style.

推荐答案

这个问题是为了扭转一些东西在URL准备好撤销之前的导入时间。这不是RedirectView本身的问题 - 它会发生在您尝试在urls.py文件中反转的任何东西，或者可能在其导入的文件中。

This problem is to do with trying to reverse something at import time before the URLs are ready to be reversed. This is not a problem with RedirectView itself - it would happen with anything where you tried to reverse in your urls.py file, or possibly in a file imported by it.

在Django的开发版本中，有一个名为 reverse_lazy 专门帮助这种情况。

In the development version of Django, there is a function called reverse_lazy specifically to help in this situation.

如果您使用的是早期版本的Django，那么这里有一个解决方案：反向Django通用视图，post_save_redirect;错误'include urlconf没有任何模式'。

If you're using an earlier version of Django, there is a solution here: Reverse Django generic view, post_save_redirect; error 'included urlconf doesnt have any patterns'.
