/* 定义Schema */ var mongoose = require(‘mongoose’); var Schema = mongoose.Schema; //先定义你自己的Schema var yourSchema = new Schema({ //… }); //定义查询函数listByQuery，名字自己起 yourSchema.statics.listByQuery(queryParams){ var query = this.find(queryParams); return yield query.exec(); }; module.exports = yourSchema;
