django-admin对搜索结果进行自定义统计，可参考代码如下：
def changelist_view(self, request, extra_context=None):
#cur1_time = datetime.now()
data_dict = {}
value = request.GET.get('q', "")
bill_cycle = request.GET.get('bill_cycle__exact', "")
resource = request.GET.get('resource__id__exact', '')
date_year = request.GET.get('success_time__year', '')
date_month = request.GET.get('success_time__month', '')
date_day = request.GET.get('success_time__day', '')
new_user = request.GET.get('new_old__exact', '')
source = request.GET.get('source__id__exact', None)
kefu=request.GET.get('member_name__kefu__id__exact','0')
#此处如果没选客服，则赋值0，下面条件根据赋值来进行数据统计，此参考代码只是临时解决并非最优
if value:
data_dict["product__name__icontains"] = value
if bill_cycle:
data_dict["bill_cycle__icontains"] = bill_cycle
if resource:
data_dict["resource__id__icontains"] = resource
if source:
data_dict["source__id__icontains"] = source
if date_year:
data_dict["success_time__year__icontains"] = date_year
if date_month:
data_dict["success_time__month__icontains"] = date_month
if date_day:
data_dict["success_time__day__icontains"] = date_day
if request.user.groups.filter(name="销售部"):
if new_user == "True":
#模型中的new_old是bool类型，request得到的是str，所以此处只是偷懒的解决方法，根据if写死
