Question

我在将Django 1.6.2项目升级到Django 1.8.4时遇到了很多障碍。让我难过的最新问题就是这个问题。当我启动我的Django dev服务器并尝试访问我的网站时，我收到以下错误：

Exception Type: ImportError at /
Exception Value: No module named account.models

Traceback:
File "/Users/me/venv/myproj_dj_18/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response

  8. from apps.admin.views import all_admins
File "/www/myproj/apps/admin/views.py" in <module>
  27. from apps.account.models import Account

这是我项目文件夹结构的一部分：

myproj
├── apps
│   ├── __init__.py
│   ├── account
│   │   ├── __init__.py
│   │   ├── admin.py
│   │   ├── apps.py
│   │   ├── forms.py
│   │   ├── models.py

│   ├── settings
│   │   ├── __init__.py
│   │   ├── base.py
│   ├── urls.py
│   ├── wsgi.py
├── manage.py

以下是我的网址文件的一部分：

# conf/urls.py
from django.conf.urls import patterns, include, url
from django.conf import settings
from django.contrib.auth.decorators import user_passes_test
from django.contrib import admin
from apps.admin.views import all_admins

urlpatterns = patterns('',
    url(r'^account/',            include('apps.account.urls')),
    url(r'^members/',            include('apps.members.urls')),
    url(r'^admin/all_admins/$',
        user_passes_test(lambda u: u.is_staff)(all_admins),
        {'template': 'all_admins.html'},
        name='all-admins'),
    url(r'^admin/review/queue/$',
        'apps.admin.views.review_queue',
        {'template': 'review_queue.html'},
        name='review-queue'),
    url(r'^admin/',              include(admin.site.urls)),
    url(r'',                     include('apps.home.urls')),
)

这些是我已安装的应用：

# apps/conf/settings/base.py
INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.admin',
    'apps.admin',
    'apps.account',
    'apps.home',
)

这是模型文件的一部分：

# apps/account/models.py
from django.db import models
class Account(models.Model):
    pass

我按照文档继承了新的AppConfig类：

# apps/account/apps.py
from django.apps import AppConfig
class AccountConfig(AppConfig):
    name = 'apps.account'

# apps/account/__init__.py
default_app_config = 'apps.account.apps.AccountConfig'

# apps/admin/apps.py
from django.apps import AppConfig
class MyAdminConfig(AppConfig):
    name = 'apps.admin'
    label = 'my_admin'
    verbose_name = 'Administration'

# apps/admin/__init__.py
default_app_config = 'apps.admin.apps.MyAdminConfig'

我已经检查过以确保我的所有路径都是相互一致的：

$ python
>>> from django.apps import apps as myproj_apps
>>> account = myproj_apps.get_app_config('account')
>>> account.name  # => 'apps.account'
>>> list(account.get_models())  # => [apps.account.models.Account]

我也可以做到这一点，没有错误：

$ python
>>> from apps.account.models import Account
>>> Account.objects.get(pk=1)

我尝试将上述所有路径从“apps.account.models”更改为“myproj.apps.account.models”，但这没有帮助。我还阅读了Django 1.7应用程序文档，但看不出我做错了什么。我的网络搜索中也没有出现任何问题。这看起来很简单。谁能看到我错过的东西？

谢谢！
