python - 'ModelOptions' 对象没有属性 'local_many_to_many'

Question

我正在尝试将 Django 项目迁移到 GAE ( Google App Engine )

问题是我在尝试登录时发现了这个错误:

'ModelOptions' object has no attribute 'local_many_to_many'

引发错误的行:

user = authenticate(username=uName,password=uPass)

部分代码:

 if request.method == 'POST':
        if request.POST['submit'] == 'Login':
            postDict = request.POST.copy()
            lForm = LoginForm(postDict)
            if (lForm.is_valid()):
                uName = request.POST['username']
                uPass = request.POST['password']
                user = authenticate(username=uName,password=uPass) 
                if user is not None:
                    if user.is_active:
                        login(request,user)
                        return HttpResponseRedirect(next)
                    else:
                        message = 'Account Deactivated'

您使用的是 django-nonrel 提供的 stock auth 应用程序吗？它不会工作，因为它需要 JOIN。安装django-permission-backend-nonrel一切都会好起来的。
