www.example.com的内容myfunction.py

from django.core import management

def funcA():
    management.call_command('customcommand')

funcA()

从终端调用www.example.com时myfunction.py,它抛出raise CommandError(“未知命令:%r”%命令名)

os.environ['DJANGO_SETTINGS_MODULE'] = 'site.settings'

在www.example.com里面myfunction.py我试过设置这个,但是还是不行。有人能帮我一下吗,可能我错过了一些重要的配置

尝试将__init__.py添加到management/commands/目录。

我通过在配置环境变量之后添加django.setup()调用解决了这个问题。
在www.example.com中myfunction.py,应进行以下更改

from django.core import management
import os
import django

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'site.settings')

django.setup()

def funcA():
    management.call_command('customcommand')

funcA()

必须包含django.setup(),因为它会在独立脚本中注册应用程序和设置中定义的命令,通常由manage.py或django-admin负责
