使用django

Question

我在heroku客户端部署twitter bootstrap时遇到问题。我的html代码没有显示它应该（对齐，特殊表格布局等）

所有都在本地工作，但我认为它与未正确传输的静态文件有关。

这是静态文件结构，但看看我在我的live heroku verson上打开“source chrome console”时的样子。

查看文件夹结构应该是什么

heroku上已部署代码的文件夹结构

看起来有些文件夹被“缝合”在一起。可能是我的问题？我应该在文件名中避免使用“ - ”和“_”吗？

感谢您的帮助。

基于额外的问题，我在settings.py文件中添加了更多信息。我按照教程来获得所有正确的东西。还安装了whitenoise，添加到wsgi.py.

Answer 1

在与hansTheFranz进行彻底讨论之后，很明显这些问题与丢失的文件有关。

我的sourcetree应用程序中使用的默认gitnore，用于与github同步，阻止了几个静态文件夹上传到我的git。从这个gitnore文件中删除这些文件夹就可以了。

感谢帮助人员！

Answer 2

转到Django的heroku静态资产文档：

Heroku Documentation: Django and Static Assets

详细说明了所有内容，在settings.py中进行了更改并安装了whitenoise，这样就可以了。
