如何在django中显示外键值而不是pk?

这里我过滤的是与django用户模型有一个单一关系的人员,下面的功能代码 def filter_staff_users(request): 也可以按我的要求工作,但我得到的问题是在消息中显示组织名称时。 organization.name 但没用。我得到了 'str' object has no attribute 'name' 当我试图转换int时 organization = int(request.GET.get('organization')) 然后它再次抛出 'int' object has no attribute 'name' .

如何在此处显示组织名称?

模特儿

class Organization(models.Model):
    name = models.CharField(max_length=255, unique=True)

    def __str__(self):
        return self.name

class Staff(models.Model):
    user = models.OneToOneField(get_user_model(), on_delete=models.CASCADE, related_name='staff')
    name = models.CharField(max_length=255, blank=True, null=True)
    organization = models.ForeignKey(Organization, on_delete=models.SET_NULL, blank=True, null=True, related_name='staff')

在添加staff_用户时,我添加了如下组织

<select  name="organization">

    {% for organization in organizations %}
        <option value="{{organization.pk}}" >{{organization.name}}</option>
    {% endfor %}

</select>

VIEW

def filter_staff_users(request):
    year = request.GET.get('year')
    month = request.GET.get('month')
    # month_name = calendar.month_name[int(month)]
    organization = request.GET.get('organization')
    print('org', type(organization))

    if year and month and organization:
        staffs = get_user_model().objects.filter(Q(staff__joined_date__year=year) & Q(staff__joined_date__month=month) & Q(staff__organization=organization))

        messages.success(request, '{} staffs found for {}  {} and {}'.format(staffs.count(), year, calendar.month_name[int(month)], organization))
