运行我的应用程序时出现“oReverseMatch at /filter”错误？这是 urls.py：

urlpatterns = patterns('myform.views',
                       url(r'^contact$', 'contact'),
                       url(r'^affiche$', 'affiche'),
                       url(r'^add$', 'add'),
                       url(r'^filter$', 'filter'),
                       url(r'^filter_display/(?P<continent>[-\w]+)/$', 'filter_display',name='FilterDisplay'),

这是我的view.py：

class FilterForm(forms.Form):
    Continent = forms.ChoiceField(choices=Select_continent())   
    Country = forms.ChoiceField(choices=Select_country())
    City = forms.ChoiceField(choices=Select_city())
    Server_Adress = forms.ChoiceField(choices=Select_adress())

def filter(request):
    if request.method == 'POST':                                                                                                                                                 
        form = FilterForm(request.POST)                                                                                                                                            
        if form.is_valid() :
            Continent = form.cleaned_data['Continent']
            Country = form.cleaned_data['Country']
            City = form.cleaned_data['City']
            Server_Adress = form.cleaned_data['Server_Adress']
            #Continent = dict(form1.fields['Continent'].choices)[Continent]
            #Country = dict(form1.fields['Country'].choices)[Country]
            #City = dict(form1.fields['City'].choices)[City]
            #Server_Adress = dict(form1.fields['Server_Adress'].choices)[Server_Adress]
            url = reverse('filter_display', args=(),   kwargs={'continent': 'America',})
            return HttpResponseRedirect(url)
    else:
        form = FilterForm()
    return render_to_response('filter.html', { 'form': form }, RequestContext(request))     


def filter_display(request, continent):
        if request.method == 'POST':                                                                                                                                                 
            form1 = FilterForm(request.POST)                                                                                                                                            
            if form1.is_valid() :
                Continent = form1.cleaned_data['Continent']
                Country = form1.cleaned_data['Country']
                City = form1.cleaned_data['City']
                Server_Adress = form1.cleaned_data['Server_Adress']
        else:
            form1 = FilterForm()
        data = Select_WHERE(continent)
        return render_to_response('affiche_continent.html', {'form1':form1, 'data':data }, RequestContext(request))

当我在 URL 中输入 'localhost:8000/filter_display/EUROPE/' 时，它可以工作。
该代码在“filter_display”中完美运行。
但是当我尝试使用视图中的“过滤器”函数传递参数时，我得到了这个错误

name您已经为该 URL提供了一个，因此您应该在调用中使用它reverse：

url = reverse('FilterDisplay', kwargs={'continent': 'America',})
