Mongoose uuid insted ObjectId

Question

我想在_id字段中使用uuid字符串来代替ObjectId。

型号/ user.js的

var uuid = require('node-uuid'); 

var userSchema = mongoose.Schema({ 
    _id: {type: String, default: uuid.v4}, 
    nick: {type: String, unique : true, default: ""}, 
    email: {type: String, default: ""}, 
    pass: {type: String, default: ""}, 
    admin: {type: Boolean, default: false}, 
    created: {type: Date, default: Date.now}, 
    modified: {type: Date, default: Date.now} 
}); 

独特之处是必要的吗？

_id: {type: String, unique : true, default: uuid.v4}, 

Answer 1

UUID的定义是唯一的，所以您不一定需要将_id定义为模型中唯一。
