如何使用feathersjs中的钩子更新mongodb数据？

Question

我是 featherjs 的新手，我创建了一项名为调查的服务。这是我的数据模型

'use strict';

// surveys-model.js - A mongoose model
// 
// See http://mongoosejs.com/docs/models.html
// for more of what you can do here.

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const surveysSchema = new Schema({
    ownerId: { type: String},
    parentId: { type: String},//Id of campaign or the community
    question: String,
    votes: [{
        voted:[String],
        answer:{type:String,enum:['answer1','answer2']}
    }]


});

const surveysModel = mongoose.model('surveys', surveysSchema);

module.exports = surveysModel;

我需要根据用户投票分别更新投票..我如何使用钩子在同一服务中进行更新...请帮助我找到答案。提前谢谢

Answer 1

你想在钩子里调用另一个服务吗？如果是这样，那么它们在hook.app.service 中可用。

hook.app.service('servicename').update(...)
