How to solve 'TemplateDoesNotExist' error in Django 4.2 while running the server?

问题

这是一个Django项目中的错误信息，表明找不到名为 "home.html" 的模板文件。您可能需要检查以下几点以解决此问题：

  1. 确保 "home.html" 文件存在于您的模板文件夹中。根据您的目录结构，它应该在 "F:\Django\geekshows\templates" 目录中。

  2. 确保在您的视图或模板中正确引用了 "home.html"。在您的视图函数中，使用 render 函数的第一个参数应该是模板文件的路径，确保路径是正确的。

  3. 检查您的Django配置。确保您的Django项目设置中的 TEMPLATES 部分已正确配置，包括 'APP_DIRS': True 以便查找应用程序目录中的模板。

  4. 如果您最近修改了模板文件或项目结构，请确保重新启动Django开发服务器，以便使更改生效。

请仔细检查这些方面，以确保 "home.html" 模板文件被正确引用和定位。

  24. Django tried loading these templates, in this order:
  26. Using engine django:

你似乎有一个名为home的视图，渲染home.html，但找不到home.html。

Raised during: geekshows.views.home
...
django.template.loaders.filesystem.Loader: F:\Django\geekshows\templates\home.html (Source does not exist)

请注意，你的应用结构似乎不符合标准，视图文件应该在应用程序内（比如.../geekshows/main/views.py），但你的似乎在项目根文件夹geekshows中。

标准结构：
geekshows/ # 项目根目录
main/ # 应用程序 main（或其他名称）
templates/
main/
home.html
models.py
views.py
...
course/ # 应用程序 course
fees/ # 应用程序 fees
geekshows/ # 与项目同名的文件夹 -> Django 请求的入口点
urls.py
wsgi.py
settings.py
manage.py

请发布视图并显示放置home.html的文件夹结构，以进一步回答你的问题。

英文:

you seem to have a view home that renders home.html but home.html cant be found

  1. Raised during:  geekshows.views.home
  2. ...
  3. django.template.loaders.filesystem.Loader: F:\Django\geekshows\templates\home.html (Source does not exist)

please note that you seem to have a non standard structure of your app as a view file should be inside an app (like .../geekshows/main/views.py) but yours seems to be in the project root folder geekshows.

standard structure:

  1. geekshows/                      # project root
  2.    main/                        # app main (or another name)
  3.       templates/
  4.           main/
  5.              home.html
  6.       models.py
  7.       views.py
  8.       ...
  9.    course/                      # app course
  10.    fees/                        # app fees
  11.    geekshows/                   # folder with same name as project -&gt; django entry point for requests
  12.       urls.py
  13.       wsgi.py
  14.       settings.py
  15.    manage.py

please post the view and show the folder structure where you placed home.html to further answer your question
