python - Heroku生产环境中的Django TemplateDoesNotExist错误但在本地开发环境中没有
问题描述
我正在尝试将我的网站发布到暂存环境,但我不断TemplateDoesNotExist
出错。我的网站由多个应用程序组成,这些应用程序将为通用元素扩展基本应用程序。当我在开发环境中查看该网站时,它按预期工作,但是当我尝试在我的暂存环境中查看它时,它会出错。
应用程序中的所有模板(基本模板除外)都包含{% extends "main/index.html "%}
在它们的顶部。

Template-loader postmortem
Django tried loading these templates, in this order:
Using engine django:
django.template.loaders.filesystem.Loader: /app/templates/main/index.html (Source does not exist)
django.template.loaders.app_directories.Loader: /app/.heroku/python/lib/python3.7/site-packages/django/contrib/admin/templates/main/index.html (Source does not exist)
django.template.loaders.app_directories.Loader: /app/.heroku/python/lib/python3.7/site-packages/django/contrib/auth/templates/main/index.html (Source does not exist)
django.template.loaders.app_directories.Loader: /app/base/templates/main/index.html (Source does not exist)
django.template.loaders.app_directories.Loader: /app/dashboard/templates/main/index.html (Source does not exist)
django.template.loaders.app_directories.Loader: /app/inventory/templates/main/index.html (Source does not exist)
django.template.loaders.app_directories.Loader: /app/magic/templates/main/index.html (Source does not exist)
django.template.loaders.app_directories.Loader: /app/.heroku/python/lib/python3.7/site-packages/django_filters/templates/main/index.html (Source does not exist)
解决方案
我弄清楚了我的问题,并觉得自己像个白痴。我的问题是我有:
{% extends "main/index.html " %}
代替
{% extends "main/index.html" %}
