Question

我有以下设置以下设置。但我的设置总是出错... MySQL版本是5，Django是最后一个版本。 Python 3.7

#!/usr/bin/env python
import os
import sys
sys.path.append("/home/test")


if __name__ == "__main__":
     os.environ.setdefault("DJANGO_SETTINGS_MODULE", "standAlone.myScript")
     from django.core.management import execute_from_command_line
     execute_from_command_line(sys.argv)

这是我的myScript：

# settings.py
from django.conf import settings


#settings.configure(
    DATABASE_ENGINE    = " ",
    DATABASE_NAME      = " ",
    DATABASE_USER      = " ",
    DATABASE_PASSWORD  = " ",
    DATABASE_HOST      = " ",
    DATABASE_PORT      = " ",
   # INSTALLED_APPS     = ("myApp")
)

from django.db import models
from myApp.models import *

这是我的settings.py：

DATABASE_ENGINE    = 'django.db.backends.mysql'
DATABASE_NAME      = 'DATABASE_NAME'
DATABASE_USER      = '****'
DATABASE_PASSWORD  = '****'
DATABASE_HOST      = '127.0.0.1'
DATABASE_PORT      = '3306'

我有以下错误：

  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/home/test/django/core/management/__init__.py", line 443, in execute_from_command_line

    mod = importlib.import_module(self.SETTINGS_MODULE)
  File "/home/test/django/utils/importlib.py", line 35, in import_module

在myScript.py的第5行中，您有#注释掉一行。然后，我认为第6行DATABASE_ENGINE = " ",将是语法错误（虽然回溯似乎不包括此内容）。

还有其他问题。导入内容的方式将导致settings.py数据库设置在myScript.py中使用第5行中的空值覆盖。除非这是你想要的，否则正确的方法（在myScript.py中）是：

# settings.py
from django.conf import settings

from django.db import models
from myApp.models import *

即，在settings.py中指定设置，不要在myScript.py中覆盖它们。

如果您确实因任何原因需要覆盖设置，那么只需删除第5行的#，即可。

下次，请尝试自己解决语法错误，这比发布到堆栈溢出要快得多。
