Heroku - 应用程序错误 - 当 DEBUG = False 时 Heroku 崩溃

Question

我刚刚想出了如何在 Whitenoise 上托管我的 static 文件，并且当 DEBUG = False 时它们被完美托管。 我不得不以这种方式托管它们，因为在生产中我不断收到 500 个错误，因为 Heroku 无法托管我的 static 文件。 这现在工作正常。 然而，我现在遇到了另一个问题。 现在，当 settings.py 中的 DEBUG = False 时，我的整个 Heroku 应用程序崩溃并显示以下页面。 仅当 DEBUG = False 时。 我最初认为它是允许的主机，但我将该值设置为“*”，这应该只允许用于测试，但我仍然遇到同样的问题。 当 DEBUG = False 时，如何阻止 Heroku 崩溃？

Answer 1

虽然可能有其他原因，但通常与 static 文件有关。

根据 Heroku 的文档，可以在此处找到：

Django 不会自动创建 collectstatic 使用的目标目录 (STATIC_ROOT)，如果它不可用。 您可能需要在代码库中创建此目录，以便在运行 collectstatic 时可用。 Git 不支持空文件目录，因此您还必须在该目录中创建一个文件。

在部署期间，Heroku 将在项目的根目录（与manage.py文件所在的目录相同）和/或您通过STATICFILES_DIRS变量在settings.py中指定的任何目录中查找static文件夹，该目录可能类似于：

STATICFILES_DIRS = ['BASE_DIR / 'static']

如果 Django 找不到这些文件夹，或者static文件夹为空，则您可能在部署过程中遇到困难。 尽管构建过程可能会成功完成，但当DEBUG设置为False时，您会收到这500 个错误，并且想知道出了什么问题。

验证static文件夹是否存在的一种方法是通过从终端运行以下命令检查是否进入 Heroku 服务器：

heroku run bash

连接到服务器后，您可以列出应用程序根目录中的目录。

ls

现在，根据您定义static和staticfiles目录设置的位置和方式，您需要验证这两个文件夹在您的应用程序中是否可用。 此处显示的示例基于以下 2 个设置：

// specifies the root directory of your static files when app is deployed.
// the output will be stored in this directory after running 
// `python manage.py collectstatic`
STATIC_ROOT = BASE_DIR / 'staticfiles'

// specifies which directories to use for static files during development 
// and which directories to look in when 
// `python manage.py collectstatic` is run
STATICFILES_DIR = [BASE_DIR / 'static']

您还需要确保您的static目录不为空； 它需要在内部有一个文件，以便 Git 能够拾取它，并且python manage.py collecstatic成功。

根据 Heroku 文档：

当 Django 应用程序部署到 Heroku 时，$ python manage.py collectstatic --noinput 在构建期间自动运行。 如果 collectstatic 步骤不成功，构建将失败。

尽管您可以通过运行heroku config:set DISABLE_COLLECTSTATIC=1 collectstatic您的构建可能会成功完成，但这很可能并最终导致错误（例如设置DEBUG=False时的 500 错误） DEBUG=False ）。

因此，即使您没有使用或没有 static 文件，在应用程序的根目录中创建一个static文件夹并转储一个虚拟文件（任何图像、js 或 ZC7A628CBA22E28EB17B5 文件在它里面）会更安全56AE2在部署期间被 Heroku 拾取。

完成此操作后，有望解决任何 500 个错误，并且您的应用程序可以在您设置DEBUG=False时运行。

最后一件事，如果您仍然遇到问题，您还可以在 Heroku 中启用collectstatic调试。 根据 Heroku 文档：

如果在构建期间 collectstatic 失败，则会提供有助于诊断问题的回溯。 如果您需要有关运行 collectstatic 的环境的其他信息，请使用 DEBUG_COLLECTSTATIC 配置。

这可以通过在终端中键入以下内容来完成：

heroku config:set DEBUG_COLLECTSTATIC=1
