sent_filter = request.GET.get('sent_filter','')
open_filter = request.GET.get('open_filter','')
delivery_filter = request.GET.get('delivery_filter','')
click_filter = request.GET.get('click_filter','')
bounce_filter = request.GET.get('bounce_filter','')
response_filter = request.GET.get('response_filter','')
unsub_filter = request.GET.get('unsub_filter','')

上面多个参数，实际比这个还多。

我是写个if判断参数有没有存在，然后写一条查询语句渲染到前端
也就是每种组合要写一条查询语句。但是发现组合太多了。。要写很多条。

请问有没有比较简便的方法？

谢谢。
