Question

我已经阅读了有关此问题的其他问题，但无法解决这个问题。

我在做什么：在我的本地PC上我有Django 1.8.5和几个应用程序，一切正常。到1.8.5我不久前从1.6.10升级了。但是当我在生产服务器上安装django 1.8.5时，我会遇到类似django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet的错误（下面的完整回溯）。

奇怪，为什么localhost上的相同代码有效？

我的猜测为什么会发生这种情况：正如Django 1.7 throws django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet所指出的那样，它可能是Pinax帐户模块问题https://github.com/pinax/django-user-accounts，但我尝试修复，错误仍然存在。

另外，如果我在服务器上重新安装django到1.6.10它可以工作，甚至可以为用户注册和授权！请帮助解决如何修复Django 1.8.5上的错误。

我附上了settings.py：

编辑：我有应用帐户Pinax帐户模块问题https://github.com/pinax/django-user-accounts，在该应用中有几个地方有＆＃39; get_user_model＆＃39;： views.py：

def create_user(self, form, commit=True, **kwargs):
    **user = get_user_model()**(**kwargs)
    username = form.cleaned_data.get("username")
    if username is None:
        username = self.generate_username(form)
    user.username = username
    user.email = form.cleaned_data["email"].strip()
    password = form.cleaned_data.get("password")
    if password:
        user.set_password(password)
    else:
        user.set_unusable_password()
    if commit:
        user.save()
    return user

以及更多：

    def send_email(self, email):
    User = get_user_model()
    protocol = getattr(settings, "DEFAULT_HTTP_PROTOCOL", "http")
    current_site = get_current_site(self.request)
    email_qs = EmailAddress.objects.filter(email__iexact=email)
    for user in User.objects.filter(pk__in=email_qs.values("user")):
        uid = int_to_base36(user.id)
        token = self.make_token(user)
        password_reset_url = "{0}://{1}{2}".format(
            protocol,
            current_site.domain,
            reverse("account_password_reset_token", kwargs=dict(uidb36=uid, token=token))
        )
        ctx = {
            "user": user,
            "current_site": current_site,
            "password_reset_url": password_reset_url,
        }
        hookset.send_password_reset_email([user.email], ctx)

和第3名：

    def get_user(self):
    try:
        uid_int = base36_to_int(self.kwargs["uidb36"])
    except ValueError:
        raise Http404()
    return get_object_or_404(get_user_model(), id=uid_int)

Answer 1

首先尝试升级到Django 1.7。并检查弃用警告。你很快就会找到有罪的模块。

Answer 2

简而言之：在位于/usr/django/engine.wsgi的Ubuntu服务器上更改wsgi.py文件（其中engine是您的项目名称）

问题出在文件 wsgi.py 的设置中：设置属于django 1.6版本，但不适用于1.8

我在Stackoverflow上看到了很多答案如何解决，但这对我没有帮助，因为我编辑了位于项目文件夹中的 wsgi.py ，但这是错误的

Django 1.8：django.core.exceptions.AppRegistryNotReady：模型还没有加载

2 个答案:
