流星Ironrouter試圖通過數據，但稱收集沒有定義

Question

使用IronRouter，我已經成功地呈現在頁面的模板。我正在嘗試將數據從一個集合傳遞到唯一頁面，但是有一個錯誤說明該集合沒有定義。由於安裝了autopublish，所以訂閱不成問題。

我從形式獲取數據，保存它，然後我想要顯示的路由頁上的數據。

到目前爲止，收集，我有：

import { Meteor } from 'meteor/meteor'; 
import { Template } from 'meteor/templating'; 
import { Works } from '../api/works.js'; 

import './work.js'; 
import './body.html'; 

Template.main.helpers({ 
    works() { 
    return Works.find({}, { sort: { createdAt: -1 } }); 
    }, 
}); 

Template.main.events({ 
    'submit .new-work'(event) { 
    event.preventDefault(); 

    const title = event.target.title.value; 
    const workBriefDesc = event.target.workBriefDesc.value; 
    const workFullDesc = event.target.workFullDesc.value; 
    const workId = this._id; 

    Works.insert({ 
     title, 
     workBriefDesc, 
     workFullDesc, 
     createdAt: new Date(), 
     owner: Meteor.userId(), 
     username: Meteor.user().username, 
     workId, 
    }); 

    event.target.title.value = ''; 
    event.target.workbriefdesc.value = ''; 
    event.target.workfulldesc.value = ''; 

    }, 
}); 

Template.collab.helpers({ 
    works: function(){ 
    return Works.findOne({_id:Router.current().params.workId}); 
    }, 
}); 

而對於IronRouter文件：

Router.route('/works/:_id', function() { 
    this.render('Collab'); 
}, { 
    name: 'collab', 
    data: function(){ 
     return Works.findOne({ _id: this.params._id}); 
    }, 
}); 

而且模板文件：

<!-- Publishing the template work --> 
<template name="main"> 
         <form class="new-work col s12"> 
          <div class="row"> 
           <div class="input-field col s6"> 
            <input id="title" type="text" class="validate"> 
            <label for="title">Name of work</label> 
           </div> 
           <div class="input-field col s6"> 
            <select> 
             <option value="" selected>Choose category</option> 
             <option value="1">Prose</option> 
            </select> 
            <label></label> 
           </div> 
          </div> 
          <div class="row"> 
           <div class="input-field col s12"> 
            <input id="workBriefDesc" type="text" length="250"> 
            <label for="workBriefDesc">Brief description</label> 
           </div> 
          </div> 
          <div class="row"> 
           <div class="input-field col s12"> 
            <textarea id="workFullDesc" class="materialize-textarea" length="10000"></textarea> 
            <label for="workFullDesc">Full description</label> 
           </div> 
          </div> 
          <div class="row"> 
           <div class="input-field col s12"> 
            <textarea id="workessay" class="materialize-textarea"></textarea> 
            <label for="workessay">Essay</label> 
           </div> 
          </div> 
          <div class="modal-footer"> 
           <button href="#!" class="modal-action modal-close waves-effect waves-grey btn-flat center" type="submit" name="action">Submit</button> 
          </div> 
         </form> 
    {{#each works}} {{ > work}} {{/each}} 
</template> 

<!-- Link to the unique page --> 
<template name="work"> 
    Go to <a href="/work/{{_id}}">work</a> 
</template> 


<!-- Unique page attached to ID --> 
<template name="collab"> 
    {{title}} <br> 
    {{workBriefDesc}} <br> 
    {{workFullDesc}} 
</template> 

這是錯誤從瀏覽器控制檯：

Answer 1

新增import { Works } from '/imports/api/works.js';到我的路由器文件。
