在heroku上使用nested_inline时，在collectstatic期间发生Django错误

Question

我正在尝试部署一个在heroku 实例上使用nested_inline 的django 应用程序。本地一切都运行良好，但我在收集静态期间在heroku服务器上遇到错误。

我按照heroku指南来让一个最小的django设置工作起来。然后我将“django-nested-inline”添加到我的requirements.txt中，将“nested_inline”添加到我的INSTALLED_APPS的末尾，并将“fromnested_inline.admin import NestedModelAdmin, NestedStackedInline”添加到我的admin.py中。

一切仍然在本地完美运行，没有任何问题。但是当我推送到heroku“git push heroku master”时，出现以下错误：

$ git push heroku master

正如它所说，forms-nested.css文件引用了类似 的图像nav-bg.gif，据我所知，这些图像似乎不存在于任何地方。但这并不能阻止 django 和nested_inline 在本地完美工作。我不知道为什么它会在 Heroku 上崩溃？

Answer 1

collectstatic 这是由于后处理方法可能发生的错误。

你可以做的是禁用 heroku 自动运行collectstatic命令：

heroku config:set DISABLE_COLLECTSTATIC=1

然后在禁用后处理方法的情况下运行collectstatic ：

heroku run python manage.py collectstatic --no-post-process --noinput

如果不是这种情况，则错误可能是您安装的nested_inline应用程序造成的。
