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：
-
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。
-
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。 -
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。 -
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。

Template-loader postmortem
Django tried loading these templates, in this order:
Using engine django:
django.template.loaders.filesystem.Loader: F:\Django\geekshows\templates\home.html (Source does not exist)
django.template.loaders.app_directories.Loader: C:\Users\soumy\AppData\Local\Programs\Python\Python311\Lib\site-packages\django\contrib\admin\templates\home.html (Source does not exist)
django.template.loaders.app_directories.Loader: C:\Users\soumy\AppData\Local\Programs\Python\Python311\Lib\site-packages\django\contrib\auth\templates\home.html (Source does not exist)
django.template.loaders.app_directories.Loader: F:\Django\geekshows\course\templates\home.html (Source does not exist)
django.template.loaders.app_directories.Loader: F:\Django\geekshows\fees\templates\home.html (Source does not exist)
When I am running server this error is comming. I am using Django 4.2 so how to over come.

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
Raised during: geekshows.views.home
...
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:
geekshows/ # project root
main/ # app main (or another name)
templates/
main/
home.html
models.py
views.py
...
course/ # app course
fees/ # app fees
geekshows/ # folder with same name as project -> django entry point for requests
urls.py
wsgi.py
settings.py
manage.py
please post the view and show the folder structure where you placed home.html to further answer your question
