Django 1.7 django.core.exceptions扔。感谢您的准备:模型还没有加载。

This is the traceback on my windows system.

I get this error when i am trying to use registration app in Django 1.7

当我试图在Django 1.7中使用注册应用程序时，我得到了这个错误。

This is what solved it for us and these folks:

这是为我们和这些人解决的问题:

Our project started with Django 1.4, we went to 1.5 and then to 1.7. Our wsgi.py looked like this:

我们的项目从Django 1.4开始，到1.5，然后到1.7。我们的wsgi。py看起来像这样:

import os

from django.core.handlers.wsgi import WSGIHandler

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
application = WSGIHandler()

When I updated to the 1.7 style WSGI handler:

当我更新到1.7风格的WSGI处理器:

import os

from django.core.wsgi import get_wsgi_application

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
application = get_wsgi_application()

Everything works now.

现在一切正常。

Running these commands solved my problem (credit to this answer):

运行这些命令解决了我的问题(归功于这个答案):

import django
django.setup()

However I'm not sure why I need this. Comments would be appreciated.

但是我不知道为什么我需要这个。评论将不胜感激。

The issue is in your registration app. It seems django-registration calls get_user_module() in models.py at a module level (when models are still being loaded by the application registration process). This will no longer work:

这个问题出现在你的注册应用程序中，看起来django注册在模型中调用get_user_module()。在模块级别上的py(当模型仍然被应用程序注册过程加载时)。这将不再起作用:

try:
    from django.contrib.auth import get_user_model
    User = get_user_model()
except ImportError:
    from django.contrib.auth.models import User

I'd change this models file to only call get_user_model() inside methods (and not at module level) and in FKs use something like:

我将把这个模型文件改为只调用get_user_model()内部方法(而不是在模块级别)，而在FKs中使用一些类似的东西:

user = ForeignKey(settings.AUTH_USER_MODEL)

BTW, the call to django.setup() shouldn't be required in your manage.py file, it's called for you in execute_from_command_line. (source)

在您的管理中不应该要求设置()。py文件，在execute_from_command_line中调用它。(源)

Just encountered the same issue. The problem is because of django-registration incompatible with django 1.7 user model.

只是遇到了同样的问题。问题在于django-registration与django 1.7用户模型不兼容。

A simple fix is to change these lines of code, at your installed django-registration module::

一个简单的解决方法是修改这些代码行，在您安装的django-registration模块中::

try:
    from django.contrib.auth import get_user_model
    User = get_user_model()
except ImportError:
    from django.contrib.auth.models import User

to::

from django.conf import settings
try:
    from django.contrib.auth import get_user_model
    User = settings.AUTH_USER_MODEL
except ImportError:
    from django.contrib.auth.models import User

Mine is at .venv/local/lib/python2.7/site-packages/registration/models.py (virtualenv)

我在当地.venv / / lib / python2.7 /网站/注册/模型。py(virtualenv)

This works for me for Django 1.9 . The Python script to execute was in the root of the Django project.

这对我来说对Django 1.9很有用。执行的Python脚本是Django项目的根。

    import django 
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "PROJECT_NAME.settings")
    django.setup()
    from APP_NAME.models import *

Set PROJECT_NAME and APP_NAME to yours

将PROJECT_NAME和APP_NAME设置为您的。

#6

Another option is that you have a duplicate entry in INSTALLED_APPS. That threw this error for two different apps I tested. Apparently it's not something Django checks for, but then who's silly enough to put the same app in the list twice. Me, that's who.

另一个选项是在INSTALLED_APPS中有一个重复的条目。这为我测试的两个不同的应用程序提供了这个错误。很显然，这不是Django检查的东西，但是谁傻到把同一个应用程序放在列表中两次。我,这是谁。

#7

Do you have a Python virtual environment that you need to enter before you run manage.py?

在运行manage.py之前，是否有需要输入的Python虚拟环境?

I ran into this error myself, and that was the problem.

我自己也遇到了这个错误，这就是问题所在。

#8

I ran into this issue when I use djangocms and added a plugin (in my case: djangocms-cascade). Of course I had to add the plugin to the INSTALLED_APPS. But the order is here important.

我在使用djangocms时遇到了这个问题，并添加了一个插件(在我的例子中是djangocms-cascade)。当然，我必须将插件添加到INSTALLED_APPS中。但这里的秩序很重要。

To place 'cmsplugin_cascade' before 'cms' solved the issue.

将cmsplugin_cascade放在“cms”解决问题之前。

#9

install django-registration-redux==1.1 instead django-registration, if you using django 1.7

如果使用django 1.7，安装django-registration-redux==1.1，而不是django注册。

Your manage.py is "wrong"; I don't know where you got it from, but that's not a 1.7 manage.py - were you using some funky pre-release build or something?

你的管理。py是“错误的”;我不知道你从哪里得到的，但这不是一个1.7。py -你使用了一些时髦的预发布版本吗?

Reset your manage.py to the conventional, as below, and things Should Just Work:

重设你的管理。py与常规，如下所示，一切都应该工作:

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "{{ project_name }}.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)
