Question

有一个模型和内联模型.. 我需要创建一个查询集，它从内联模型中检索数据并在模板中返回一个for循环。看起来像我的代码不工作但是任何人都可以帮忙吗？

class Account(models.Model):
    uuid = ShortUUIDField(unique=True)
    name = models.CharField(max_length=80)
    desc = models.TextField(blank=True)
    address_one = models.CharField(max_length=100)

    def __str__(self):
        return u"%s" % self.name

class Rates(models.Model):
     airline = models.CharField(max_length=30, blank=True, verbose_name= 'AIRLINE')
     dest = models.CharField(max_length=3,blank=True,verbose_name= 'DEST')

     name= models.ForeignKey (Account, default = False, related_name="rates")
         def __str__(self):
        return self.airline

My for loop should retrieve all rates in case account name is XXX

def rates_acc(request, account):
    account = Account.objects.get(name = xxx)
    rates = [x for x in account.rates.all()]
    context = {

        'rates': Account.objects.filter (name__name__icontains = 'xxx'),
       }
    return render(request,'accounts/account.html',context)

Answer 1

我的for循环应检索所有费率，以防帐号名称为XXX

然后这个：

'rates': Account.objects.filter(name__name__icontains='xxx)

应该是这样的

'rates': Rates.objects.filter(name__name='XXX')

或者，如果您想获得帐户名称包含XXX的所有费率

'rates': Rates.objects.filter(name__name__icontains='XXX')

对于内联模型的循环查询集
