execute_from_command_line(sys.argv) 这一句很简单的命令。而这个命令,来自: from django.core.management import execute_from_command_line 这里的sys.argv,实际上是: ['manage.py', 'runserver', '0.0.0.0:8000'] 而在 execute_from_command_line函数里,实际上,是生成ManagementUtility类,并运行:execute方法。
execute_from_command_line(sys.argv) if __name__ == '__main__': main() 我们可以看到,在manage.py文件中,Django的设置模块被定义为环境变量DJANGO_SETTINGS_MODULE,默认值为'myproject.settings'。接着,它尝试从django.core.management中导入execute_from_command_line,这个函数是用来执行命令行管理任务的。
然后execute_from_command_line(sys.argv) 它会调用ManagementUtility(argv).execute() 而execute()中,会先调用settings.INSTALLED_APPS,再调用django.setup()方法,然后调用self.fetch_command(subcommand).run_from_argv(self.argv)方法 ***先看settings.INSTALLED_APPS理论上就是访问settings.py中的INSTALLED配置 为什么?
问Django：<module> execute_from_command_line(sys.argv)中的文件"manage.py"，第10行EN使用django开发，对python manage.py ***命令模式肯定不会陌生。比较常用的有runserver，migrate。。。 本文讲述如何自定义扩展manage命令。 1、源码分析 manage.py文件是通过django-admin startproject project_name生成的。 1）...
