为基本的Django heroku应用程序提供服务时,我可以看到一些静态文件加载得很好(/static/lang-logo.png)。但是,当我添加main.css并运行python3 manage.py collectstatic
时,css文件永远不会显示,在我的index.html中的导入也永远不会加载
我已经准备好,whitenoise最适合在django应用程序中提供静态文件,所以我正在使用它,并根据这里对类似问题的许多回答设置了settings.py
Collectstatic似乎正在工作(见下文)。几天来,我一直在用我的脑袋来思考这个问题,在这里我已经讨论了几十个相关的问题,但似乎没有什么能解决这个问题。我已经到了互联网的尽头,现在你是我唯一的希望。下面是我的代码,如果我意识到我遗漏了一些相关内容,我会更新问题

将
STATIC\u URL
更改为/STATIC/
,出于测试目的,只需设置STATICFILES\u DIR=['hello/STATIC/hello']
。Whitenoise不一定要排在第二位。我在底部运行我的应用程序,它与我在Heroku上的Django多租户应用程序配合得非常好。我相信当你现在推到Heroku时,你可能需要再做一次collectstatic
。如果它在第一次构建后抱怨你的静态文件,就像Heroku说的那样禁用它
编辑:顺便说一下,Heroku不支持SQLite,您需要迁移到postgres。这是我做过的事,从来没有回头看。您所要做的就是更改数据库信息和引擎,然后就可以开始了。好的,可能无法解决您的问题,但我注意到您的WhiteNoise中间件位于错误的位置。它必须是列表中的第二个,而不是最后一个。这可以改变一切。太棒了!我很有信心。
