如何在自定义搜索表单中显示实际的关键字和计数？

我的Haystack自定义搜索工作正常，但我在显示实际关键字和计数方面遇到了困难。

当我使用默认的Haystack网址时，{{ query }}会显示实际的关键字。

使用自定义搜索表单时，{{ query }}和{{ query.count }}为空。

form.py

class BusinessSearchForm(SearchForm):

def no_query_found(self):
    return self.searchqueryset.all()

def search(self):
    sqs = super(BusinessSearchForm, self).search()

    if not self.is_valid():
        return self.no_query_found()

    return sqs

view.py

def business_search(request):
form = BusinessSearchForm(request.GET)
businesslist = form.search()
paginator = Paginator(businesslist, 5) 
page = request.GET.get('page')
try:
    businesslist = paginator.page(page)
except PageNotAnInteger:
    businesslist = paginator.page(1)
except EmptyPage:
    businesslist = paginator.page(paginator.num_pages)

return render_to_response('businesslist.html', {'businesslist': businesslist},
                            context_instance=RequestContext(request))

template.html

Your query {{ query }} has returned {{ query.count }} result{{ businesslist|pluralize }}

Answer 1

您需要传递query作为上下文。

这样的事情：

context = {
    'query': form.cleaned_data['q'],
    'businesslist': businesslist,
    'paginator': paginator,
}

return render_to_response('businesslist.html', context, context_instance=RequestContext(request))

您可以使用paginator.count获取结果数量。

<强> template.html

Your query {{ query }} has returned {{ paginator.count }} result{{ paginator.count|pluralize }}.

Answer 2

这非常简单，因为您可以返回上下文（这是字典）并在前端对其进行解析

在views.py文件中

    context = {
        'query': query,
        'result_list': Regs.objects.filter(pk__in=list_id),
    }

    return context

template.html中的解析为

    {{ object_list.result_list|length }} is the number of results for the query and  "{{ object_list.query }}" is the actual query entered by the user.
