我正在使用Django过滤器应用在我的网站上构建搜索。这是代码：

class PropertyFilter(django_filters.FilterSet):
city = django_filters.ModelMultipleChoiceFilter(queryset=City.objects.all(), widget = CheckboxSelectMultiple)
trade_type = django_filters.ModelMultipleChoiceFilter(queryset=Trade.objects.all(), widget = CheckboxSelectMultiple)

class Meta:
    model = Property
    fields = ['city', 'trade_type']

问题在于，当用户标记两个城市时，Django过滤器仅通过最后一个URL参数（此案例中的城市2）过滤对象：

http://example.org/lt/list/city=1&city=2

Models.py：

class City(models.Model):
    name = models.CharField(max_length=250, verbose_name=_('Name'))

也许我做错了什么？

我正在尝试使用Ajax提交我的压缩表单集.当请求不是ajax时,代码可以正常工作.但每当我尝试实现Ajax时,我都会收到ValidationError:[u'ManagementForm数据丢失或被篡改']

我的观点:

def App(request):
    lectures = Lecture.objects.all()
    TopicFormSet = modelformset_factory(Topic, extra=0)
    SummaryFormSet = modelformset_factory(Summary, extra=0)
    tquery = Topic.objects.all()
    squery = Summary.objects.all()
    #saving formsets:
    if request.method == 'POST' and request.is_ajax():
        t_formset = TopicFormSet(request.POST)
        s_formset = SummaryFormSet(request.POST) #formset instances
        if t_formset.is_valid() and s_formset.is_valid():
            t_formset.save() and s_formset.save()
            zipped = zip(t_formset.forms, s_formset.forms) #saving them with new data
        else:
                return HttpResponse("not valid formsets, dude") # for testing purposes
    else: #request=GET
        t_formset = TopicFormSet(queryset = tquery)
        s_formset = SummaryFormSet(queryset = squery)
        zipped = zip(t_formset.forms, s_formset.forms) …
