Python 3,Django 2.0
我刚刚结束官方Django教程,我正在研究高级部分 - “如何编写可重用的应用程序”
似乎我至少部分成功,我可以通过管理界面访问问题和选择,但当我尝试显示http://127.0.0.1:8000/polls/时,我收到此错误:TemplateDoesNotExist at / polls / 1 / < / p>
我在http://127.0.0.1:8000/polls/1/
尝试访问详情页面时遇到类似错误我查看了所有可以解决的疑难问题,我的主要问题是 - 如何访问打包到应用中的模板?我看到错误的是Django试图在主项目目录中找到应用程序模板(即:/tutorial/templates/polls/detail.html),但它们应该在我从pip导入的模块“内部”。
你真的应该以这种方式将模板打包到应用程序中吗?我尝试将模板文件重新放回tutorial / templates / polls /并且它工作正常,但这违背了我认为应该是“可重用性”的原因,因为打包的应用程序将没有它自己的模板。
我能找到的答案似乎更适用于旧版本的Django,并使用了TEMPLATE_LOADERS设置......任何人都知道是否有办法在Django 2中设置它?

请记住将templates
目录包含在MANIFEST.in
文件中。有关详细信息,请参阅packaging your app的第6步。
答案 1 :(得分:1)
此处存在的问题是:该文件已被命名为manifest.in
,当需要将其大写为MANIFEST.in
时。节日快乐!
