用对象字典：
e.g:
def ViewIndex(request):
open_wis = None
search = None
search_wis = None
closed_produicts={}
open_wis = map_productname_in_object(Wi.get_all_open_wi())
productnames = get_all_productname()
close_wis = map_productname_in_object(Wi.get_all_close_wi())
sign_wis = map_productname_in_object(Wi.get_all_sign_wi())
return render(request,"index.html",{"user": request.user,"productnames":productnames,"open_wis":open_wis,
"close_wis":close_wis,"sign_wis":sign_wis,"search":search,"search_wis":search_wis,
"closed_produicts":closed_produicts,
})
