模型未被识别

Question

我试图将一个模型从一个应用程序应用到另一个应用程序的视图中，但Django无法识别它的名称，并给出以下错误：

local variable 'user_status' referenced before assignment

这是我的模型：

class user_status(models.Model):
    name = models.CharField(max_length=500)
    code = models.IntegerField()

    def __unicode__(self):
        return u'%s' % self.name

这是我的观点：

def verifica_pgto(request):
    if request.user.is_authenticated():
        user = request.user
        date_joined = user.date_joined.replace(tzinfo=None)
        dif  =  datetime.now() - date_joined
        try:
            user_details = UserDetails.objects.get(user=user)
            if user_details.status == 'ativo':
                params = {'user_status':'ativo'}
            else:
                params = {'user_status':'inativo'}
        except:
            # cria user details
            if dif.total_seconds() > 7:
                status = 'inativo'
                user_status = user_status.objects.get(name = 'inativo')
            else:
                status = 'ativo'
                user_status = user_status.objects.get(name = 'inativo')

            d = UserDetails(
                user = user,
                created_at = datetime.now(),
                status = user_status,            
                end_access = dt.timedelta(days=7)
            )
            d.save()
        if user_status == '':
            params = {'user_status':'ativo'}
        else:
            params = {'user_status':'inativo'}
        return params

这就是我将模型导入到视图.py你知道吗

from payments.models import *

我也试过这样做：

from payments.models import *
from payments.models import user_status

Answer 1

尽量不要使用与相同的实例名称同学们，试试看这是：

from django.shortcuts import get_object_or_404
from payments.models import user_status

def verifica_pgto(request):
    if ....
        us = get_object_or_404(user_status)
    ......
        us.objects.get(name = 'inativo')
    ....
