mongoose这样设置schema为什么老出错 - CNode技术社区

 db.once('open',function(){
 var m39 = mongoose.Schema({
 id:Number,//采集的地址
 date:{type:Date,default:Date.now},
 question:{
 content:String,
 author:String
 },
 answer:{
 id:{
 content:String,
 author:String
 }
 },
 url:String
 })
 var c_39_url = mongoose.model('c_39_url',m39)
 }

求改进
