模板不会在 Meteor FlowRouter 中呈现

Question

我需要你的帮助来找出我的代码有什么问题。我有一个 HomeLayout 分为 3 个部分；

header
边
主要

我有一个对话列表；它将在主要部分呈现，它包含一个名为 One_Conversation 的 子部分 ：当我点击对话时，它被呈现

好吧，没关系：我的问题是当我点击另一个对话时，模板不会呈现

这是我的代码： /routes.js

FlowRouter.route('/conversation', {
    name: 'Conversation',

    action(){
        BlazeLayout.render('HomeLayout', {side: 'Messages', main: 'Conversation_list'});
    }
});
FlowRouter.route('/conversation/:idConversation', {
    name: 'oneConversation',
    action(){
        BlazeLayout.render('HomeLayout', {side: 'Messages', main: 'Conversation_list', conversation: 'One_conversation'});
    }
});

/HomeLayout.html

<template name="HomeLayout">

        <div class="app header-fixed sidebar-fixed aside-menu-fixed aside-menu-hidden">
            {{> Header}}

            <div class="app-body">
                <div class="sidebar">
                    {{> Template.dynamic template=side }}
                </div>
                <main class="main">
                    <div class="container-fluid">
                        {{> Template.dynamic template=main }}
                    </div>
                </main>

            </div>
            {{> Footer}}
        </div>
</template>

/Conversation_list.html

<template name="Conversation_list">
<div class="messages">
////code
////code
////...
</div>
 <conversation class="content">
            {{> Template.dynamic template=conversation }}
        </conversation>
</template>

最后在我的 Conversation_list.events 中点击对话

FlowRouter.go('/conversation/:idConversation', {idConversation:this._id});

这是/OneConversation.html模板

<template name="One_conversation">
    {{#with oneConversation}}

            <div class="contact-profile">
                {{#if isDefault}}
                    <img src="{{contact.profile_pic}}" alt="" />
                    <p>{{contact.first_name}} {{contact.last_name}}</p>

                {{else}}
                    <img src="http://emilcarlsson.se/assets/harveyspecter.png" alt="" />
                    <p>{{contactLiveChat.first_name}} {{contactLiveChat.last_name}}</p>
                {{/if}}
                <div class="social-media">
                    <i class="fa fa-facebook" aria-hidden="true"></i>
                    <i class="fa fa-twitter" aria-hidden="true"></i>

                </div>

            </div>
            <div class="messages">
                {{#each allMessagesOfConversation}}
                    <ul>
                        {{#if isFirst}}

                            <li class="replies">
                                <img src="http://emilcarlsson.se/assets/harveyspecter.png" alt="" />
                                <p>{{message}} </p>
                            </li>
                        {{else}}

                            <li class="sent">
                                <img src="{{contactM.profile_pic}}" alt="" />
                                <p>{{message}}</p>
                            </li>
                        {{/if}}
                    </ul>
                {{/each}}
            </div>


            <div class="message-input">
                <div class="wrap">
                    <input type="text" placeholder="Write your message..." />
                    <i class="fa fa-paperclip attachment" aria-hidden="true"></i>
                    <button class="submit"><i class="fa fa-paper-plane" aria-hidden="true"></i></button>
                </div>
            </div>
    {{/with}}
</template>

这是/OneConversation.js

import { Template } from ‘meteor/templating’;

import ‘./One_conversation.html’;
import {Meteor} from “meteor/meteor”;
var idConversation=’’;
var typeConversation=’’;
var token=’’;

Template.One_conversation.onCreated(function One_conversationOnCreated() {
idConversation = FlowRouter.getParam(“idConversation”);
// typeConversation= Session.get(‘typeConversation’);

// token= Session.get(‘token’);
// psid= Session.get(‘psid’);
// console.log("OneConversation psid: ",psid);
// console.log("OneConversation token: ",token);
//
// psid= FlowRouter.getParam(“psid”);
// console.log("OneConversation psid liveChat: ",psid);

Meteor.subscribe('allConversations');
Meteor.subscribe('allMessages');
Meteor.subscribe('allContacts');
Meteor.subscribe('allHotels');
Meteor.subscribe('allImMessenger');
});

Template.One_conversation.rendered = function () {

};

Template.One_conversation.helpers({

    return Messages.find({idConversation: idConversation},{sort: {createdAt: 1}}).map(function(message) {

        if (message.typeMessage ==="1") {

        }
    });

},
oneConversation: function() {

},

Template.One_conversation.events({

    if(Session.get('typeConversation') ==='facebook'){

                $(".message-input input").val('');

            }

        });
    }
},
});

我做错了什么？

Answer 1

好吧，它已修复，我的问题出在 idConversation ;

我在会话 conversationList.events 中设置对话的 ID，并在 oneConversation Helper 中获取它，因此代码变成这样

/Conversation_list.js

import { Template } from 'meteor/templating';
import './conversationList.html';
import {Meteor} from "meteor/meteor";

    Template.conversationList.onCreated(function conversationListOnCreated() {
        Meteor.subscribe('allConversations');
        Meteor.subscribe('allMessages');
        Meteor.subscribe('allContacts');
        Meteor.subscribe('allHotels');
        Meteor.subscribe('allImMessenger');
    });
    var psid="";
    var token="";

    Template.conversationList.rendered = function () {
    };

    Template.conversationList.helpers({
        toUpperCase: function(str) {
            return str.toUpperCase();
        },
        allMessagesOfConversation: function() {
            return Messages.find({idConversation: Session.get('conversationId')},{sort: {createdAt: 1}}).map(function(message) {
                if (message.typeMessage ==="1") {
                    message.isFirst=true;
                    return message;
                }else {
                    return message;
                }
            });
        },
        oneConversation: function() {
            return Conversations.findOne({_id: Session.get('conversationId')});
        },

        allConversations: function() {
            return Conversations.find({idHotel: Hotels.findOne({contractId: Meteor.users.findOne({_id: Meteor.userId()}).profile.contractId})._id,archived:false},{sort: {createdAt: -1}}).map(function(conversation, index) {
                if (index === 0) {
                    conversation.isFirst = true;
                }

                }else{
