流星错误调用方法['questions.insert]：方法'questions.insert'找不到

Question

我试图将一个表单（包含测试问题）提交到称为问题的mongo集合中。我引用了运行服务器端代码的文件，我认为它应该都能正常工作。 这里是我的代码：

//add.html 

<template name="add"> 
 
    <h3>This is the add questions page</h3> 
 
    <form class="add-questions"> 
 
    <label>Subject</label> <br> 
 
    <input type="text" name="subject" placeholder="Maths" value="subject"> <br> 
 
    <label>Topic</label> <br> 
 
    <input type="text" name="topic" placeholder="I.E. Algebra" value="topic"> <br> 
 
    <label>Level</label> <br> 
 
    <input type="number" name="level" value="3"> <br>

它看起来像你使用Meteor 1.3 +的ES2015模块支持和/imports目录延迟加载。考虑到这一点，在您的add.js文件中，您正在导入questions.js文件，其中包含您的questions.insert方法定义。这意味着您的视图可以在客户端正确找到此方法。但是，方法需要在客户端和服务器端都可用，或者仅在服务器端提供。要解决您的错误，您需要确保您的方法在服务器端也可用，通过在启动时引用questions.js文件。喜欢的东西：

/server/main.js

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

/imports/startup/server/register_api.js

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

这将触发服务器上的Meteor.methods电话并注册缺失的questions.insert方法。
