流星錯誤調用方法['questions.insert]：方法'questions.insert'找不到

Question

我試圖將一個表單（包含測試問題）提交到稱爲問題的mongo集合中。我引用了運行服務器端代碼的文件，我認爲它應該都能正常工作。 這裏是我的代碼：

//add.html 

<template name="add"> 
 
    <h3>This is the add questions page</h3> 
 
    <form class="add-questions"> 
 
    <label>Subject</label> <br>

它看起來像你使用Meteor 1.3 +的ES2015模塊支持和/imports目錄延遲加載。考慮到這一點，在您的add.js文件中，您正在導入questions.js文件，其中包含您的questions.insert方法定義。這意味着您的視圖可以在客戶端正確找到此方法。但是，方法需要在客戶端和服務器端都可用，或者僅在服務器端提供。要解決您的錯誤，您需要確保您的方法在服務器端也可用，通過在啓動時引用questions.js文件。喜歡的東西：

/server/main.js

import '/imports/startup/server/register_api'; 

/imports/startup/server/register_api.js

import '../../api/questions.js'; 

這將觸發服務器上的Meteor.methods電話並註冊缺失的questions.insert方法。
