1.创建一个 user(被关联的表)
const UserSchema = new mongoose.Schema({undefined
name: { // 用户姓名
type: String,
},
loginname: { // 用户姓名
type: String,
},
});
const TABLE_NAME=“users”;
const DATABASE_NAME=“node_dev”;
mongoose.model(‘users’, UserSchema );
2.创建一个 article
var Schema = mongoose.Schema;
var articleSchema = new Schema( {undefined
content: {type: String},
author_id: {undefined
type: Schema.ObjectId,
ref:‘users’ //关联用户表
},
}
);
find(obj).sort(sort).skip(skip).limit(pageSize).populate(“author_id”);
注:author_id则变成一个对象直接取对象属性即可
