只需意识到您可以轻松地覆盖命令，就像使用具有相同名称的命令制作应用程序一样。
因此，我创建了一个应用程序，并创建了一个与runserver相同名称的文件，然后扩展了runserver基类以在运行之前添加新功能。
例如，我想在runserver启动之前运行$ $ watch watch命令，并使其在runserver执行期间一直运行。
"""
Start $compass watch, command when you do $python manage.py runserver
file: main/management/commands/runserver.py
Add ´main´ app to the last of the installed apps
"""
from optparse import make_option
import os
import subprocess
from django.core.management.base import BaseCommand, CommandError
from django.core.management.commands.runserver import BaseRunserverCommand
from django.conf import settings
class Command(BaseRunserverCommand):
option_list = BaseRunserverCommand.option_list + (
make_option('--adminmedia', dest='admin_media_path', default='',
help='Specifies the directory from which to serve admin media.'),
make_option('--watch', dest='compass_project_path', default=settings.MEDIA_ROOT,
help='Specifies the project directory for compass.'),
)
def inner_run(self, *args, **options):
self.compass_project_path = options.get('compass_project_path', settings.MEDIA_ROOT)
self.stdout.write("Starting the compass watch command for %r\n" % self.compass_project_path)
self.compass_pid = subprocess.Popen(["compass watch %s" % self.compass_project_path],
shell=True,
stdin=subprocess.PIPE,
stdout=self.stdout,
stderr=self.stderr)
self.stdout.write("Compas watch process on %r\n" % self.compass_pid.pid)
super(Command, self).inner_run(*args, **options)
这样很好。
