Append text to input after selecting one from list - ractivejs

<input type="submit" on-click='toggle("Dropdown")'>
<input type="text" value="{{category.name}}">
{{#if Dropdown}}
<div class="dropdown">
<ul>
<li>Custard Pudding</li>
<li>Coffee Pudding</li>
</ul>
{{/if}}
ractive.on('select', function(event) {
this.observe( 'category.name', function ( newValue, keypath ) {
this.set( keypath, '' + newValue );
});
})
Understand that in JQuery $('dropdown a').text() and append it to input would work.
Only question I have is how to grab the text and set it to input when on-click "select". Searched example and tried but it is not doing anything. Perhaps the way is wrong.
Please help

You can get the value from event.node:
ractive.on('select', function(event) {
this.set( 'category.name', '' + event.node.textContent );
})
You could do that inline too:
<li>Custard Pudding</li>
But if the <li> are generated from data (or you could make it that way) you can set directly
<input type="submit" on-click='toggle("Dropdown")'>
<input type="text" value="{{category.name}}">
{{#if Dropdown}}
<div class="dropdown">
<ul>
{{#each ['Custard Pudding', 'Coffee Pudding'] }}
<li>{{this}}</li>
{{/each}}
</ul>
{{/if}}

How to update document of particular user id

Basically what I want to do is, just update user details.so when
I input user ID all the other details of user are displayed in
textbox. Then I can edit anything.
Below is my js code:
Template.body.onCreated(function() {
this.currentTextBox = new ReactiveVar();
});
Template.body.events({
"keyup .new-task1"(event, instance) {
instance.currentTextBox.set(event.target.value);
}
});
Template.body.helpers({
dbs() {
const instance = Template.instance();
return Dbs.find({'user_id':instance.currentTextBox.get()});
}
});
Template.temp.events({
"submit .sub"(event) {
const target= event.target;
const name1 =target.name.value;
const add1 =add.value;
const r1 = target.r.value;
const const1 = target.const.value;
console.log(doc_id1);
Dbs.update({"user_id" : "pid"},{"name" : "name1","r" : "r1","const"
: "const"});
}
});
Now the problem is I am not able to update the edited field, though the value of edited field is sent to js file from html.anyone help me to solve this issue as I am new to meteor and mongo db.

Welcome to Meteor :)
You have to use $set attribute when you are updating document,
use as below and let me know.
Dbs.update({"user_id" : "pid"},{$set:{"name" : "name1","r" : "r1","const" : "const"}});

Also go through Mongo Update Query example to know how to update a document when you directly use mongo shell.
Remember there are few differences when you directly use Mongo Shell commands and Meteor Collections.

meteor database insert in global collection

The code below should insert the selected item value in the Tasks collection, retain the info for later use, and a headerLabel should show the task selected. I am not able to get the headerLabel to show the task when the click .menuItem function runs. Thanks
Tasks = new Mongo.Collection('tasks');
Template.mainMenu.events({
'click .menuItem': function(event){
Tasks.insert({menuItem: $(event.currentTarget).data('value')});
}
});
Template.header.helpers({
headerLabel: function( id ){
return Tasks.findOne({_id: id}).menuItem;
},
tasks: function(){
return Tasks.find();
}
});
<template name="mainMenu">
<div class="container">
<div class="row">
<section class="col-xs-12">
<div class="list-group">
{{#each menuItems}}
<a href="#" class="list-group-item menuItem" data-value={{menuItem}}>
<img src="/abc.png">
{{menuItem}} <span class="badge">></span>
</a>
{{/each}}
</div>
</section>
</div>
<template name="header">
<h1><button class="col-xs-2 mainMenu" type="button">☰</button></h1>
<h3>
<label class="col-xs-8 text-center">
{{#if headerLabel}} {{headerLabel}} {{else}} Select an item {{/if}}
</label>
</h3>
<h1><button class="col-xs-2" type="button">⋮</button></h1>
</template>
Assuming that the click can happen multiple times, you'll need to pass an _id for the appropriate task into your helper:
Tasks = new Mongo.Collection('tasks');
Template.mainMenu.events({
'click .menuItem': function(event){
Tasks.insert({menuItem: $(event.currentTarget).data('value')});
}
});
Template.header.helpers({
headerLabel: function( id ){
var task = Tasks.findOne({_id: id});
if( task ) {
return task.menuItem;
}
},
tasks: function() {
return Tasks.find();
}
});
So what I'm doing there is saying find one task's menuItem that has the ID passed to the helper. I also added a tasks helper to get all tasks. So your template might look something like:
<template name="mainMenu">
{{#each task in tasks}}
<h4>{{headerLabel task._id}}</h4>
<!-- Additional code here... -->
{{/each}}
</template>
You'll obviously need to customize the HTML to your specific situation, but that should give you the gist. Hope that helps!

Meteor IF statement should be firing

I'm stumped as to why part of my code isn't displaying when the session variable is set to true. When the user selects a certain option from the dropdown, based on the value, it changes the warmerselected to TRUE. I have tracked this in the console, and it works just fine.
Here is my code:
HTML:
<div class="item">
<div class="ui label">Product Type:</div>
<select id="ProductType" name="ProductType">
{{#each ProductTypes}}
<option value="{{ProductTypeAbbrev}}">{{ProductTypeName}}</option>
{{/each}}
</select>
</div>
{{#if warmerselected}}
<div class="item">
<div class="ui label">Name:</div>
<input type="text" name="ProductName" placeholder="Enter Product Name">
</div>
{{/if}}
JS:
Session.setDefault("warmerselected", false);
Template.addProduct.events({
'change #ProductType': function (e) {
var selitem = $("#ProductType").val();
if(selitem == "WA") {
Session.set("warmerselected",true)
}else {
Session.set("warmerselected",false);
}
}
});
Template.addProduct.helpers({
warmerselected: function(){
return Session.get("warmerselected");
}
});
Session isn't meant to be helper in HTML, you have to create one

filter collection on dropdownlist change

i'm trying to filter my collection on dropdownlist change , here's my code in the template manager
Template.postsList.events({
"change .typeselection": function(e, t){
console.log("drop changed");
return Session.set("type", $("[name=type]").val());
}
});
here's my template code :
<template name="postsList">
<select name="type" id="type" value="" placeholder="type the adress" class="form-control typeselection">
<option value="Restaurant">Restaurant</option>
<option value="Hotel">Hotel</option>
<option value="Shop">Shop</option>
</select>
<div class="posts">
{{#each postsWithRank}}
{{> postItem}}
{{/each}}
{{#if nextPath}}
<a class="load-more" href="{{nextPath}}">Load more</a>
{{else}}
{{#unless ready}}
{{> spinner}}
{{/unless}}
{{/if}}
</div>
</template>
From my understanding,this code works for you
//on dropdown change we are setting the new value in session
Template.postsList.events({
"change .typeselection": function(e, t){
console.log("drop changed");
Session.set("type", $("[name=type]").val());//no need to return anything here
}
});
//whenever the session variabe changes this code will re run
Template.postsList.helpers({
"postsWithRank": function(){
//assuming you have type field in your collection and you want filter on that field
return Posts.find({"type":Session.get("type")});
}
});
//so this code will display the selected relative data
{{#each postsWithRank}}
{{> postItem}}
{{/each}}

How to reload (re render) template in Meteor

I am working on a chat app that supports multiple languages. The basics of the app is working fine however I have small problem when changing chat rooms.
Each room is setup to support 2 languages. When sending a chat message you can choose which language you are sending the message in. This is done by clicking on a small icon of a flag which toggles between the 2 flag icons. The template for this is:
<template name="chatBar">
<div id="chatBar" class="input-append input-prepend">
<form id="chatForm">
<span class="add-on"><img src="/images/flags-iso/flat/16/{{chatMessageLang}}.png" id="lang"></span>
<input id="chatMessageLanguage" type="hidden" value="{{chatMessageLang}}">
<input id="chatMessageTarget" type="hidden" value="{{chatMessageTargetLang}}">
<input class="input-xxlarge" id="chatMessage" type="text" placeholder="← choose your language and then type your message here…">
<button class="btn" id="sendNewMessage" type="submit">Send</button>
</form>
</div>
and is called from another template:
<template name="chat">
{{> chatroom}}
<div id="chatWindow">
<ul>
{{#each chats}}
<li class="{{messageClass}} {{_id}}">
<img src="/images/flags-iso/flat/16/{{langOriginal}}.png">
{{langTo.flagicon}}
{{user}}:
<span class="message" lang="{{langOriginal}}">{{original}}</span>
{{#if translated}}
<span class="message" lang="{{langTranslated}}">{{translated}}</span>
{{/if}}
{{#if correction}}
<i class="icon-remove"></i>
<span class="friendCorrection">{{correction}}</span>
{{/if}}
<span class="messageOptions">{{{messageOptions}}}</span>
</li>
{{/each}}
</ul>
</div>
{{> chatBar}}
</template>
The problem I have is when I change chatrooms the language options are being retained from the previous chatroom I was in. The code for setting the languages for the chatbar is:
Template.chatBar.helpers({
chatMessageLang: function() {
//return getCurrentChatroomInfo().langFrom.iso;
return Meteor.user().profile.langNative;
},
chatMessageTargetLang: function() {
var chatroomLang1 = getCurrentChatroomInfo().langFrom.iso;
var chatroomLang2 = getCurrentChatroomInfo().langTo.iso;
if(Meteor.user().profile.langNative == chatroomLang1){
return chatroomLang2;
} else {
return chatroomLang1;
}
}});
function getCurrentChatroomInfo(){
return Chatrooms.findOne({_id : Router.current().params['_id']})
}
How do I make the variable chatMessageTargetLang reactive to the loaded chatroom (each chatroom has their own route).
Thanks
Adam
