from django.views.generic.list import ListView 

class VenderListView(ListView): 
    queryset=VendorModel.objects.all() 

    def get_context_data(self, **kwargs): 
     context = super().get_context_data(**kwargs) 
     context['total_active_records'] = self.queryset.filter(Status='Active').count() 
     return context 

List_Template.html：

<div>Total Active Vendors: <span> {{ total_active_records }}</span></div>

これはUmar Asghar's answerに基づいて、私のために働きました。

class IndexListView(ListView): 
    template_name = "ePROC/Base/index.html" 
    model = CreateReqModel 
    context_object_name = 'reqlists' 
    queryset=CreateReqModel.objects.all() 
    paginate_by = 10 

    def get_context_data(self, **kwargs): 
     context = super(IndexListView, self).get_context_data(**kwargs) 
     context['total_active_records'] = self.queryset.filter(Status='Initiate').count() 
     context['range'] = range(context["paginator"].num_pages) 
     return context
