我正在尝试按照 https://docs.djangoproject.com/en/dev/ref/applications/ 上的文档为我的一个名为“文章”的 Django 应用程序设置自定义应用程序配置。 ，但在执行 ./manage.py check(或任何其他管理命令，例如 ./manage. py 运行服务器)

这是项目树

projectname
    ├── apps
    │   ├── articles
    │   │   ├── admin.py
    │   │   ├── apps.py
    │   │   ├── __init__.py
    │   │   ├── migrations
    │   │   │   ├── 0001_initial.py
    │   │   │   └── __init__.py
    │   │   ├── models.py
    │   │   ├── templates
    │   │   │   └── articles
    │   │   ├── templatetags
    │   │   │   ├── articles_tags.py
    │   │   │   └── __init__.py
    │   │   ├── tests.py
    │   │   ├── urls.py
    │   │   └── views.py
    │   ├── __init__.py

在 settings.py 中安装的应用:

INSTALLED_APPS = (
  'grappelli',
  'django.contrib.admin', 
  'django.contrib.auth', 
  'django.contrib.contenttypes', 
  'django.contrib.sessions', 
  'django.contrib.messages',
  'django.contrib.staticfiles',
  'django.contrib.humanize', 
  'grappelli.dashboard', 
  'mptt', 
  'sekizai', 
  'pytils', 
  'sorl.thumbnail',
  'sefaro.apps.utils', 
  'sefaro.apps.seo', 
  'sefaro.apps.staticpages', 
  'sefaro.apps.statictext', 
  'sefaro.apps.usersettings', 
  'sefaro.apps.navigation', 
  'sefaro.apps.slideshow',
  'sefaro.apps.articles', 
) 

articles/__init__.py的内容:

# articles/__init__.py
default_app_config = 'articles.apps.ArticlesConfig'

articles/apps.py 的内容:

# -*- coding: utf-8 -*-
from django.apps import AppConfig
from django.utils.translation import ugettext_lazy as _


class ArticlesConfig(AppConfig):

    name = 'articles'
    verbose_name = _(u'Articles')

我的 INSTALLED_APPS 中有 'projectname.apps.articles'

只是为了确保我确实拥有所有这些文件并且没有弄乱路径

>>> from projectname.apps.articles.apps import ArticlesConfig
>>> ArticlesConfig
<class 'projectname.apps.articles.apps.ArticlesConfig'>

一切都导入就好了...

但是:

(vagrant)vagrant@vagrant-ubuntu-trusty-32:~/django$ ./manage.py check
Traceback (most recent call last):
  File "./manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/home/vagrant/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 385, in execute_from_command_line
    utility.execute()
  File "/home/vagrant/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 354, in execute
    django.setup()
  File "/home/vagrant/local/lib/python2.7/site-packages/django/__init__.py", line 21, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "/home/vagrant/local/lib/python2.7/site-packages/django/apps/registry.py", line 85, in populate
    app_config = AppConfig.create(entry)
  File "/home/vagrant/local/lib/python2.7/site-packages/django/apps/config.py", line 112, in create
    mod = import_module(mod_path)
  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
ImportError: No module named articles.apps

最佳答案

根据具体的Django项目结构(所有应用程序都位于projectname/apps/模块)，应该使用包含项目名称的完整路径。

作为文档 https://docs.djangoproject.com/en/dev/ref/applications/#django.apps.AppConfig.name说:

AppConfig.name

Full Python path to the application, e.g. 'django.contrib.admin'.

所以应该是:

# articles/apps.py:
from django.apps import AppConfig
from django.utils.translation import ugettext_lazy as _


class ArticlesConfig(AppConfig):

    name = 'projectname.apps.articles'
    verbose_name = _(u'Articles')

和

# articles/__init__.py
default_app_config = 'projectname.apps.articles.apps.ArticlesConfig'

关于python - Django 1.7 应用程序配置导入错误 : No module named appname. 应用程序，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25785667/
