【问题描述】：
我正在尝试使 Django-plans 应用程序正常工作。除了/admin/plans/plan/（/admin/plans/order/、/admin/plans/userplan/ 等工作正常）之外，一切似乎都正常。
当我点击 Django-admin 中的计划时，它会返回：
TemplateDoesNotExist at /admin/plans/plan/
我不明白为什么它不存在。我查看了django-plans admin.py 文件，似乎Plan 没有指定任何特殊模板。
你知道有什么问题吗？

我无法进入计划，其他页面正常工作。

一个 hacky 解决方案是创建一个名为“admin”的空白应用程序，并将其添加到 INSTALLED_APPS（在最底部）。管理应用程序将有模板文件夹和模板文件夹内的另一个名为“admin”的文件夹。然后你可以在'admin'文件夹中拥有'plans'文件夹。作为替代方案，您还可以将“管理员”文件夹添加到您已有的应用程序中。
-
@user2707389 我想知道是什么问题，为什么django找不到这样的模板。你知道吗？谢谢
-
我将解释 django 查找模板的方式：在您的情况下，它会遍历 INSTALLED_APPS 中包含的每个应用程序内的所有“模板”文件夹，并在其中查找“管理员”文件夹“计划”文件夹存在。在您的情况下，任何地方都没有“管理员”文件夹，它正在引发错误。只需在任何应用程序内的任何模板文件夹中创建一个管理文件夹，它就可以工作。或者把你的代码放到 github 上告诉我。
-
我试图在我的一个应用程序中添加管理文件夹，但没有帮助。如果它有帮助，我会感到惊讶，因为我可以访问其他型号的 Plan 应用程序。我在问题底部添加了屏幕截图。
-
我在下面发布了这个问题的正确答案。创建一个虚拟文件夹不是解决方案。
