Question

我正在尝试将一个表单（包含测试问题）提交到名为Questions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>
    <label>Marks</label> <br>
    <input type="number" name="marks" value="5"> <br>
    <label>Date</label> <br>
    <select name="month">
      <option> - Month - </option>
      <option value="jan">January</option>
      <option value="feb">February</option>
      <option value="mar">March</option>
      <option value="apr">April</option>
      <option value="may">May</option>
      <option value="jun">June</option>

      <option value="sep">September</option>
      <option value="oct">October</option>
      <option value="nov">November</option>
      <option value="dec">December</option>
    </select>
    <select name="year">
      <option> - Year - </option>
      <option value="16">2016</option>
      <option value="15">2015</option>
      <option value="14">2014</option>
      <option value="13">2013</option>
      <option value="12">2012</option>
      <option value="11">2011</option>
      <option value="10">2010</option>
      <option value="9">2009</option>
      <option value="8">2008</option>
      <option value="7">2007</option>
      <option value="6">2006</option>
      <option value="5">2005</option>
      <option value="4">2004</option>
      <option value="3">2003</option>
      <option value="2">2002</option>
      <option value="1">2001</option>
      <option value="0">2000</option>
    </select> <br>
    <label>Question</label> <br/>
    <textarea name="question" class="question" id="question" form="add-question" placeholder="Please enter the question here as plane text" value="questionArea"></textarea> <br>
    <label>Awnser</label> <br/>
    <textarea name="answer" class="answer" form="add-question" placeholder="Please enter the question here as plane text" value="answerArea"></textarea> <br>
    <input id="submitbutt" type="submit" name="submit" value="Submit"> <a href="/" id="cancel">Cancel</a> <br>
  </form>
</template>

//add.js

// questions.js

import { Meteor } from 'meteor/meteor';
import { Mongo } from 'meteor/mongo';
import { check } from 'meteor/check';

export const Questions = new Mongo.Collection('questions');

if (Meteor.isServer) {
  // This code only runs on the server
  // Only publish events that belong to the current user
  Meteor.publish('questions', function questionsPublication() {
    return Questions.find();
    console.log("published questions");
    //return Venues.find();
  });
}

Meteor.methods({
  'questions.insert'(id, subject, topic, level, marks, date, question, answer) {
    console.log("run questions.insert");
 
    // Make sure the user is logged in before inserting a task
    if (! this.userId) {
      throw new Meteor.Error('not-authorized');
    }
 
    Questions.insert({
		id,
		subject,
		topic,
		level,
		marks,
		date,
		question,
		answer
    });
  },
});

非常感谢任何帮助。：）

您似乎正在使用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，您要导入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提供，或者只在服务器端提供。要修复错误，您需要通过在启动时引用questions.js文件来确保您的方法在服务器端也可用。类似的东西：

<强> /server/main.js

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

<强> /imports/startup/server/register_api.js

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

这将触发您在服务器上的Meteor.methods来电，并注册缺少的questions.insert方法。

Meteor错误调用方法['questions.insert]：未找到方法'questions.insert'
