django ListView的使用 ListView中获取url中的参数值方式

from django.views.generic import ListView,DetailView
from xxxx.models import Model_Name
class Colortag_view(ListView):
 #context_object_name = '如果不指定的话在html页面中 可以使用object_list获取' 
 context_object_name = 'object_list'
 #template_name='html页面所在目录'
 template_name='caradmin/colortags/colortags.html'
 #自定义查询方法
 def get_queryset(self):
  #获取url 中的值 比如http://127.0.0.1/admin/colortags/?name_text=红色
  print(self.request.GET.dict())
  return Model_Name.objects.filter(**self.request.GET.dict())

from . import views
urlpatterns = [
 path('colortags/', views.Colortag_view.as_view(), name = 'modelname_list'),
]

<!-- 点击类别跳转到则展示相应的分类 -->
 $("#p_type").change(function(){
 var type = $(this).val()
 location.href = '/backweb/good_list/?type='+type
 })

<!-- 关键字查询 -->
function select_goods(){
 var context=$('#context').val()
 var type = $('.select').val()
 
 if (context){
  location.href = '/backweb/good_list/?type='+type+'&context='+context
 }else{
  location.href = '/backweb/good_list/?type='+type
 }
 
 
}

def good_list(request):
 if request.method == 'GET':
  page_num = int(request.GET.get('page', 1))
  type = request.GET.get('type',0)
  context = request.GET.get('context','')
  # 如果拿不到分类则将type_id设置为0
  if not type:
   type_id = int(type)
  else:
   type_id = int(type)
  # 所有的分类
  type_list = FoodType.objects.all()
  # 根据相应的分类查找相应的商品
  # 如果type_id不为0则获取相应分类的商品
  if not type_id:
   goods = Goods.objects.all()
  else:
   goods = Goods.objects.filter(goods_type_id=type_id)
 
  # 如果有搜索条件则按照搜索条件模糊查询
  if context:
   goods = Goods.objects.filter(goods_type_id=type_id,productname__contains=context)
   if not goods:
    goods = Goods.objects.filter(goods_type_id=type_id,productname__contains=context[-1])
