Meteor - 从备忘录列表中显示单个备忘录页面 [英] Meteor - Display single memo page from memos list

问题描述

我现在正在拔头发.无法为我的备忘录应用显示单个备忘录详细页面.我尝试了数十种解决方案.有时我可以看到一毫秒的数据，然后它就消失了.我在 Iron Router 中做了路由

Im pulling my hair out right now. Cant get to display single memo detailed page for my memos app. I tried tens of solutions. Sometimes i can see data for a milisecond then it dissapears. I did route in Iron Router

// router.js 

    this.route('memo',{
       path: '/memo/:_id', 
        data: function() { return Memos.findOne({id: this.params._id}); }
    });

我写了助手(不知道为什么铁路由器会处理这个，对吗?)

I wrote helper ( not sure why if iron router handles this, right ? )

    //helpers.js

    Template.memo.helpers({
        memo: function(){ return Memos.findOne({id: this._id})}
    });

Template.memos.events({
    'click #remove-memo': function(event,template){
       console.log('memo removed : ' + this._id);
        Memos.remove(this._id);
    },
    **'click #li-body': function(event, template){
        console.log('entering li body : ' + this._id + ' title: ' + this.title);
        Router.go('/memo/'+this._id);
    }**
});

整个列表的模板

    //memos.html
   <template name="memos"> 
        <ul>
            {{#each memos}}
            <li class="notes-main">
                <span id="remove-memo" class="ex icon-close"></span>
                <a class="no-decoration" **href="{{pathFor 'memo' }}**">
                <span id="li-body" class="no-decoration">
                    <span class="notes-title">{{this.title}}</span>
                    <span class="notes-author">{{author}}</span>
                    <span class="notes-body-prev">{{body}}</span>
                </span>
                </a>
            </li>
            {{/each}}
        </ul>
  </template>

然后是单个备忘录模板

//memo.html

<template name="memo">
    title : {{title}}
    <br>
    body: {{body}}

</template>

不能让它工作.我在这里错过了什么?控制台显示: "entering li body : zj9y3y3mNvQ6uK7Eg title: zxxxxxxxxxx" "**NaN**zxxxxxxxxxxxxxxx" 所以它似乎检索到正确的数据，但它没有被渲染 (?) ，我也不知道 wht 'NaN' 是在所有消息体前面做的.任何有关如何显示单个备忘录的帮助，非常感谢.

Cant get this to work. What am I missing here ? Console shows : "entering li body : zj9y3y3mNvQ6uK7Eg title: zxxxxxxxxxx" "**NaN**zxxxxxxxxxxxxxxx" So it seems to retrive correct data but it doesnt get rendered (?) , also Ive no ide wht 'NaN' is doing in front of all messages bodies. Any help on how to get single memo displayed, much appreciated.

推荐答案

有一个错字:

Memos.findOne({id: this.params._id});

应该

Memos.findOne({_id: this.params._id});

或者只是

Memos.findOne(this.params._id);
