关于Django错误消息TemplateDoesNotExist在/

标签： django django-views

我正在尝试通过Django为博客申请，但不会显示首页（post_list.html）。 将显示以下错误消息。

 TemplateDoesNotExist at /
 blogapp3/post_list.html
 Request Method:    GET
 Request URL:   http://127.0.0.1:8000/
 Django Version:    1.11.4
 Exception Type:    TemplateDoesNotExist
 Exception Value:   
 blogapp3/post_list.html
 Exception Location:    F:\01_pro\kaso3\lib\site-packages\django\template\loader.py in select_template, line 53
 Python Executable: F:\01_pro\kaso3\Scripts\python.exe
 Python Version:    3.6.2

 Template-loader postmortem

 Django tried loading these templates, in this order:

 Using engine django:
 django.template.loaders.filesystem.Loader: F:\01_pro\blogpro3\blogapp3\templates\blog\blogapp3\post_list.html (Source does not exist)
django.template.loaders.app_directories.Loader: F:\01_pro\kaso3\lib\site-packages\django\contrib\admin\templates\blogapp3\post_list.html (Source does not exist)
django.template.loaders.app_directories.Loader: F:\01_pro\kaso3\lib\site-packages\django\contrib\auth\templates\blogapp3\post_list.html (Source does not exist)
django.template.loaders.app_directories.Loader: F:\01_pro\blogpro3\blogapp3\templates\blogapp3\post_list.html (Source does not exist)

我曾被指出其他网站的文件结构错误，但我认为这个文件似乎并不奇怪。文件结构如下。

我要注意的是错误消息中的以下部分。

Template-loader postmortem

 Django tried loading these templates, in this order:

 Using engine django:
 django.template.loaders.filesystem.Loader: F:\01_pro\blogpro3\blogapp3\templates\blog\blogapp3\post_list.html (Source does not exist)

上述路径应该适用于以下路径。

  

F：\ 01_pro \ blogpro3 \ blogapp3 \模板\博客\ post_list.html

但是，我不知道如何修复上述路径。 如果你告诉我如何解决这个问题，我很高兴。

1 个答案:

答案 0 :(得分：1)

您的文件结构确切地确认了错误说明：没有名为“blogapp3”的模板目录，因此没有名为“blogapp3 / post_list.html”的模板。

您应该将模板移动到“blogapp3”目录中。
