Django-admin: TemplateDoesNotExist at /admin/plans/plan/

Posted 2023-02-24

技术标签:

【中文标题】Django-admin: TemplateDoesNotExist at /admin/plans/plan/【英文标题】： 【发布时间】：2017-09-03 01:38:25 【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。

【问题讨论】：

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。 【参考方案1】：

对于遇到此确切错误的其他人，问题是您正在使用django-ordered-model 包，但您尚未在settings.py 中将ordered_model 添加到您的INSTALLED_APPS。

autoslugfield 进入 django-admin 界面？

找不到命令：django-admin.py

django-admin:command not found的解决办法

django-admin.py 不是内部或外部命令

在 Windows 7 上将“django-admin.py”路径添加到命令行

，我就弄懂了 Python Django 的 django-admin 命令行工具集
