Django setting.py错误

Question

我有下面的代码和下面的设置。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：

Traceback (most recent call last):
  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
    utility.execute()
  File "/home/test/django/core/management/__init__.py", line 382, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)
  File "/home/test/django/core/management/__init__.py", line 252, in fetch_command
    app_name = get_commands()[subcommand]
  File "/home/test/django/core/management/__init__.py", line 101, in get_commands
    apps = settings.INSTALLED_APPS
  File "/home/test/django/utils/functional.py", line 184, in inner
    self._setup()
  File "/home/test/django/conf/__init__.py", line 42, in _setup
    self._wrapped = Settings(settings_module)
  File "/home/test/django/conf/__init__.py", line 93, in __init__
    mod = importlib.import_module(self.SETTINGS_MODULE)
  File "/home/test/django/utils/importlib.py", line 35, in import_module
    __import__(name)
  File "/home/test/standAlone/myScript.py", line 6
    DATABASE_ENGINE    = "django.db.backends.mysql",
    ^

Answer 1

在myScript.py的第5行，您有一个#，它注释掉一行。然后，我认为第6行的DATABASE_ENGINE = " ",将是一个语法错误(尽管回溯似乎没有包括这一点)。

还有其他的问题。在myScript.py中，导入内容的方式将导致第5行中的空值覆盖settings.py数据库设置。除非这是您想要的，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 *

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

如果出于某种原因您确实需要覆盖这些设置，那么只需删除第5行的#，就可以正常工作了。

下一次，请尝试自己解决语法错误，这将比posting到堆栈溢出快得多。
