如何在featherjs中使用hook更新mongodb数据

Question

我是featherjs的新手，我创建了一个名为survey的服务。

'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单独

更新投票。.我如何使用钩子在同一服务中进行更新...请帮我找到答案，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(...)
