Question

我正在尝试按照此处的步骤进行操作：

http://dev.svetlyak.ru/optional-email-in-django-comments-en/

使Django评论应用中的“电子邮件地址”字段可选。具体来说，我创建了一个名为“mycomments.py”的文件，其中包含以下内容：

from django import forms
from django.contrib.comments.forms import CommentDetailsForm
from django.utils.translation import ungettext, ugettext_lazy as _

class CommentForm(CommentDetailsForm):
    email = forms.EmailField(label=_("Email address"), required=False)

def get_form():
    return CommentForm

并将其放在我的Django项目的根文件夹中（包含manage.py和settings.py的文件夹）。然后，我将“mycomments”添加到settings.py文件中，如下所示：

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.admin',
    'django.contrib.comments',
    'blogs',
    'mycomments',
)

COMMENTS_APP = 'mycomments'

但是当我做'python manage.py runserver'时，我收到以下错误：

Unhandled exception in thread started by <bound method Command.inner_run of <django.contrib.staticfiles.management.commands.runserver.Command object at 0x8bb208c>>

for entry in package.__path__:  # No __path__, then not a package.

AttributeError: 'module' object has no attribute '__path__'

开发服务器无法启动。我做错了吗？

Django应用程序应该（至少）包含__init__.py和models.py个文件的目录。因此，请创建mycomments目录，将代码放入__init__.py并在其中添加空models.py。
