一、快速通道 1.1 名词解释 Schema : 一种以文件形式存储的数据库模型骨架,不具备数据库的操作能力 Model :由Schema发布生成的模型,具有抽象属性和行为的数据库操作对 Entity :由Model创建的实体,他的操作也会影响数据库 注意: 1.本学习文档采用严格命名
Schema gotcha type, when used in a schema has special meaning within Mongoose. If your schema requires usingtypeas a nested property you must use object notation: newSchema({broken:{type:Boolean},asset:{name:String,type:String// uh oh, it broke. asset will be interpreted as String}});new...

1.4 Schema.Types NodeJS中的基本数据类型都属于Schema.Type,另外Mongoose还定义了自己的类型 //举例:var ExampleSchema=new Schema({name:String,binary:Buffer,living:Boolean,updated:Date,age:Number,mixed:Schema.Types.Mixed,//该混合类型等同于nested_id:Schema.Types.ObjectId,//主键_fk:Schema.Types.ObjectId...
