Question

如何在现有的views.py中实现SearchView？我已经有了CBV，并在urls.py中添加为/ moderate并希望在其中应用搜索表单。但总是得到“结果没有找到结果。”

这是我的/中等页面，包含3个表单，使用SearchView和模板中教程的一段代码。

这是来自/搜索页面，其中包含网址（r'^ search / $'，include（'haystack.urls'））

urls.py

urlpatterns= [
    url(r'^search/', include('haystack.urls')),
    url(r'^moderate/', Moderate.as_view(), name='moderate'),
]

views.py

class Moderate(SearchView):

    @method_decorator(staff_member_required)
    def dispatch(self, *args, **kwargs):
        return super(Moderate, self).dispatch(*args, **kwargs)

    #model = Ad
    template_name = 'adapp/ad_moderate.html'
    #template_name = 'search/search.html'

    paginator_class = DiggPaginator
    paginate_by = 10
    ad_type = None
    ad_sub_type = None

    def get_queryset(self):
        qs = super(Moderate, self).get_queryset().filter(ad_type__isnull=False,
                                                           ad_sub_type__isnull=False)

        return qs

    def get_context_data(self, **kwargs):
        context = super(Moderate, self).get_context_data(**kwargs)
        context['filter'] = ModerateFilter(self.request.GET)

        return context

    # define method to recieve fields from form, and change data accordings
    def post(self, request, *args, **kwargs):
        selected = request.POST['selected']
        record = Ad.objects.get(pk=int(selected))
        form = ModerateForm(request.POST, instance=record)
        if form.is_valid():
            form.save(commit=True)
            return HttpResponseRedirect('')

    def get_model(self):
    # my model, with one search should be
        return Ad

{{ object.title }}

{{ object.name }}
{{ object.city }}

Answer 1

get_context_data():
    context['search'] = SearchForm(self.request.GET).search()

会解决问题。

这意味着，我应该创建表单并从.save（）方法发送返回，而不是类似django的表单实例。
