Question

我正在使用django 1.7并且我创建了这个管理命令：

文件结构：

app/
    __init__.py
    management/
               __init__.py
               commands/
                        __init__.py
                        modal_asign.py

代码：

from django.core.management.base import BaseCommand, CommandError
from webinar.models import Webinar

class Commands(BaseCommand):

    help = 'Assign modal link to every webinar'

    def handle(self):
        latest_webinar = Webinar.objects.all().order_by('-webinar_date')[0]
        for webinars in latest_webinar:
            print "http://webinar.academiaa2.com/webinars/#displayModal" + webinars

我尝试使用python manage.py modal_asign

进行测试时遇到此错误

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/home/rafael/venv/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 385, in execute_from_command_line
    utility.execute()

  File "/home/rafael/venv/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 42, in load_command_class
    return module.Command()
AttributeError: 'module' object has no attribute 'Command'

Answer 1

您的班级名称为Commands，而django希望将其命名为Command。因此错误。

更改

class Commands(BaseCommand):

到

class Command(BaseCommand):

AttributeError：'module'对象没有属性'Command'
