Django quertset、set的序列化

import json

# 序列化queryset
def xuliehuaQueryset(request):
    querylist = models.LsTable.objects.all()
    querylist_json = serializers.serialize("json",querylist )
    return HttpResponse(querylist_json)

# 序列化set
def xuliehuaQueryset(request):
    set = {"status":"true","model":"info"}
    set_json = json.dumps(querylist)
    return HttpResponse(set_json)

# 序列化含有queryset的set，此时返回的queryset是一个个的字母列表形式
def xuliehuaQueryset(request):
    querylist = models.LsTable.objects.all()
    set ={"status":"true","querylist":serializers.serialize("json",querylist)}
    set_json  = json.dumps(set )
    return HttpResponse(set_json)


# 序列化含有queryset的set，此时返回的queryset才是object列表形式
def xuliehuaQueryset(request):
    querylist = models.LsTable.objects.all()
    set ={"status":"true","querylist":json.loads(serializers.serialize("json",querylist))}
    set_json  = json.dumps(set )
    return HttpResponse(set_json)
