Django Auth 1.11模板不存在'登录'

时间：2018-03-18 03:18:26

标签： django django-templates django-authentication django-login

我一直在谷歌搜索并尝试这一点而且无法获得登录表单。

我一直关注这个tutorial，我已经重建了几次，希望能抓住一个我错过的小错误。我也一直在谷歌搜索错误和潜在的导致无济于事。

我的问题是： 当我运行我的Django应用并尝试访问http://localhost:9000/login/时，我遇到两个错误，当我点击刷新时来回切换在浏览器中。

错误1

Django tried loading these templates, in this order:

Using engine django:

django.template.loaders.filesystem.Loader: /home/vagrant/gst/tools/tools/templates/login.html (Source does not exist)

错误2

Error during template rendering
In template /home/vagrant/gst/tools/templates/base.html, error at line 17

Reverse for '' not found. '' is not a valid view function or pattern name.

17                                      <span class="sr-only">Toggle navigation</span>

我不知道该怎么做。对于 ERROR 1 ，该文件确实存在。我还注意到，当我点击浏览器刷新按钮时，每隔几次点击登录模板的路径就会来回切换：

/home/vagrant/gst/tools/tools/templates/login.html

和

/home/vagrant/gst/tools/templates/login.html

当加载了正确的路径时，我得到 ERROR 2 ，这也让我感到困惑，我不相信我有第17行的问题作为错误状态。我已经确认css静态文件中存在类标记。我试图将所有文件设置为完全权限777，因此我排除了权限问题。

非常感谢帮助。我的配置如下：

尝试在名为tools的模板中创建一个文件夹，并将所有模板保存在该文件夹中 这是django文档中建议的方法 也不要忘记更改工具/ login.html的路径

答案 1 :(得分：0)

感谢parth patil的回复。所做的就是为我的错误添加一个额外的目录。我确实在其他帖子中看到了关于模板文件夹结构的相同内容，所以我确信它是有效的。 ^ __ ^

我找到了解决方案。我认为我的解决方案中至少有一部分是我的 urls.py 文件中缺少的内容：

from django.views.generic.base import TemplateView

我按照page

重建了我的应用
