ContentType没有声明显式的app_label [英] ContentType doesn't declare an explicit app_label

问题描述

我正在使用Apache和mod_wsgi将Django 1.10项目部署到Ubuntu服务器上.我遇到以下无法解决的500错误:

I am deploying a Django 1.10 project onto an Ubuntu server with Apache and mod_wsgi. I am getting the following 500 error which I can't solve:

RuntimeError:模型类 django.contrib.contenttypes.models.ContentType没有声明 明确的app_label，并且不在INSTALLED_APPS的应用程序中.

RuntimeError: Model class django.contrib.contenttypes.models.ContentType doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

settings.py中的installed_apps:

installed_apps in settings.py:

INSTALLED_APPS = [
    'django.contrib.sites',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'dashboard',
]

wsgi.py:

sys.path.append('/home/x_dashboard/x_dashboard/')

activate_this = os.path.expanduser("/home/x_dashboard/.venv/bin/activate_this.py")
execfile(activate_this, dict(__file__=activate_this))

os.environ['PYTHON_EGG_CACHE'] = '/home/x_dashboard/x_dashboard/.python-egg'
os.environ['DJANGO_SETTINGS_MODULE'] = 'x_dashboard.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

Apache配置:

<VirtualHost *:80>
   #ServerName example.com
   #ServerAlias www.example.com
   #ServerAdmin [e-mail]

   DocumentRoot /home/x_dashboard/x_dashboard/

   #ErrorLog /var/www/html/example.com/logs/error.log
   #CustomLog /var/www/html/example.com/logs/access.log combined

   WSGIScriptAlias / /home/x_dashboard/x_dashboard/x_dashboard/wsgi_local.py

   #Alias /robots.txt /var/www/html/example.com/public_html/robots.txt
   #Alias /favicon.ico /var/www/html/example.com/public_html/favicon.ico
   #Alias /images /var/www/html/example.com/public_html/images
   Alias /static /var/www/x_dashboard/static

   <Directory /home/x_dashboard/x_dashboard/x_dashboard/>
     <Files wsgi.py>
     Order deny,allow
     Allow from all
     Require all granted
     </Files>
   </Directory>
</VirtualHost>

Django文档说，不属于install_apps中定义的应用程序的模型需要app_label.但是，"django.contrib.contenttypes" 是在installed_apps中定义的.

The Django documentation says that an app_label is required for models which do not belong to an app defined in installed_apps. However, 'django.contrib.contenttypes' is defined in installed_apps.

任何帮助表示赞赏.

推荐答案

对于其他正在解决此错误的人:我通过将'django.contrib.contenttypes'移动到settings.py中我install_apps列表的顶部来解决了该问题.

For anyone else struggling with this bug: I solved it by moving 'django.contrib.contenttypes', to the top of my installed_apps list in settings.py.

我也搬了

import django
django.setup()

到install_apps之后. 该线程很有帮助.

to after installed_apps. This thread was helpful.
