使用Django和Heroku的控制台中的静态文件出现404错误

时间:2018-12-19 20:26:55

标签: python django heroku

当我推到Heroku时,我可以执行收集静态操作。现在的问题是我不确定将它们存储在服务器上时如何引用它们。

例如,对于我的样式表,我收到404错误: <link rel="stylesheet" type="text/css" href="/static/bower_components/bootstrap-material-design/dist/css/material.css" />

这是控制台中导致404的URL:GET https://tixblast-membership.herokuapp.com/static/bower_components/bootstrap-material-design/dist/css/material.css net::ERR_ABORTED 404 (Not Found)

要更改设置的哪一部分以确保在正确的位置显示?我运行heroku run python manage.py findstatic --verbosity 2 css/styles.css 来显示它在哪里寻找静态文件,并返回: /app/.heroku/python/lib/python3.7/site-packages/django/contrib/admin/static /app/.heroku/python/lib/python3.7/site-packages/rest_framework/static

那么我需要在设置中包括上述目录之一吗?

我以为我在进行静电收集工作后会没事的,这是我的settings.py:

我的样式表:

{% load staticfiles %}


<link rel="stylesheet" type="text/css" href="{% static 'bower_components/bootstrap/dist/css/bootstrap.css' %}" />

这是django根据错误屏幕在其中寻找模板的地方:

Using engine django:

django.template.loaders.filesystem.Loader: /app/static/index.html (Source does not exist)
django.template.loaders.app_directories.Loader: /app/.heroku/python/lib/python3.7/site-packages/django/contrib/admin/templates/index.html (Source does not exist)
django.template.loaders.app_directories.Loader: /app/.heroku/python/lib/python3.7/site-packages/django/contrib/auth/templates/index.html (Source does not exist)

不适合我的情况,请尝试删除STATICFILES_FINDERS设置。我认为这对于用白噪声提供静态服务不是必需的。无论如何我都不使用它。另外,我只有MIDDLEWARE而不是MIDDLEWARE_CLASSES。除了那些小的更改,我只想说尝试在本地服务器上使用Debug = False运行您的应用程序,看看是否遇到问题。

尝试将BASE_DIR设置更改为:

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

当使用静态文件Django应用时,您不应在模板中对静态文件URL进行硬编码,请尝试以下操作以正确设置静态文件。

  • 确保django.contrib.staticfiles包含在INSTALLED_APPS中。

  • 在设置文件中,定义STATIC_URL

示例:

STATIC_URL = '/static/'

在模板中,使用static模板标记通过配置的STATICFILES_STORAGE为给定的相对路径构建URL:

{% load static %}
<img src="{% static "my_app/example.jpg" %}" alt="My image">

我修复了它,我在Heroku中添加了NodeJS构建。那将bower_components安装在正确的文件夹中。我使用的是Python和Angular,所以我拥有前者的buildpack,而没有后者。
