Init.py 用于本地 settings.py 而不是生产 settings.py DJANGO

Question

我用 init.py、base.py、本地创建了一个设置文件夹。 py 和 production.py 但 Heroku 地址（主机）总是尝试使用本地设置。

当我从“127.0.0.1”访问它时，该应用程序工作正常，但当我尝试从 Heroku 生成的网址“XXX.herokuapp.com”访问它时显示 'disallowed host' 错误消息。 "XXX.herokuapp.com" 仅在运行 production.py 设置时是允许的主机。此外，该特定设置文件中的 DEBUG = False，所以我想我不应该详细说明错误消息

感谢您的帮助！

这是我的 manage.py :

#!/usr/bin/env python
"""Django's command-line utility for administrative tasks."""
import os
import sys


def main():
    """Run administrative tasks."""
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'Kosmeoapp.settings.production')
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


if __name__ == '__main__':
    main()

这是我的 init.py 文件：

from .base import *

from .production import *

try:
   from .local import *
except:
   pass

这是我的 local.py 文件：

Answer 1

更新环境密钥

尝试在 env 文件中放入类似环境的密钥作为

ENVIRONMENT = TEST

并使用 manage.py 到 select 适合生产或本地设置的设置。情况下使用。我在现实生活中的可部署项目中这样做过，它在生产环境和本地环境中都有效。

我的设置文件夹中有这些文件

我已经像这样更新了我的 manage.py

Here dep is the environment key which says whether the server is in development or deployment.

结论

为当前环境添加密钥并select 明智地设置。

Answer 2

在您的生产代码中更改 manage.py 中的以下设置。

Change the DJANGO_SETTINGS_MODULE to point to your production.py file.

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "<Your_app.settings.production>")

Init.py 用于本地 settings.py 而不是生产 settings.py DJANGO

Init.py goes for local settings.py rather than production settings.py DJANGO

python

deployment

django

settings

heroku

更新环境密钥

结论
