I'm new to EmberJs and I'm working on a project that I need to add properties in javascript and css in templantes generated by ember-cli, my difficulty is in finding the javascript and css files
When I search the project for the class or id, it shows me only what is in the dist that can not be changed
Can anyone with emberJS experience help me make these changes?

I can seem to find a good answer for my problem. I have a sidebar template which contains a div for each item my model contains. When I have hundreds of items to render, it takes up to 8-10 seconds to render the template. I am using ember-data.
How can I render the items that are loaded before it finishes fetching the entire model?
Here is my template :
{{#each conv in model itemController='singleconv'}}
{{#if (equals conv.url selectedSubuserEmail)}}
<div class="conversation-content-wrapper" {{action "clickConv" conv preventDefault=false}}>
<div class="history-message-assigned in-progress-closed" style="display:none;"><p><i class="icon-x"></i>Conversation closed</p></div>
<div class="history-message-assigned in-progress-assignation" style="display:none;"><p><i class="icon-assign"></i>Conversation assigned</p></div>
<div class="history-message-assigned in-progress-reopen" style="display:none;"><p><i class="icon-re-opened"></i>Conversation re-opened</p></div>
<div class={{conv.selectedClass}}>
<div class="conversation-time-history">{{{conv.status}}}</div>
<div class="conversation-details">
<span class="unread-numbers"></span>
{{input type='checkbox' class='chk-conversation' checked=conv.isChecked}}
<span class="conversation-name">{{conv.customer.name}}</span>
<span class="phone-number">{{conv.customer.cellPhoneNumber}}</span>
<p class="conversation-text">{{conv.lastMessage}}</p>
</div>
</div>
</div>
{{/if}}
{{/each}}
This is the main problem in ember's rendering which is getting much better by time, Ember connects all your binding to your created models so it re-renders the view on every added model, and hence the delay.
And I've been in the same situation, you have a couple of solutions here
1- Using Ember.ListView
You can use Ember list-view which is an Ember plug-in that adds lazy rendering to a List of items, very useful if you have items that can be displayed in the same height in pixels.
2- Using Ember Cloaking
Ember Cloaking is about the same as list-view but has flexible heights, although you still need to compute them before rendering.
3- Using visibility checker like waypoints
I've done this myself and its a little tedious but plug-in free none the less
You create a variable in your component that is set to true when it's visible in the waypoint.
sample code, not a real one
export default Ember.Component.extend({
visible:false,
didInsertElement:function() {
var waypoint = new Waypoint({
element: this.$()[0],
handler: function(direction) {
this.set('visibile',true)
}.bind(this)
})
}
})
Then Move your content into this component
And then inside this component:
{{#if visibile}}
<div class="conversation-content-wrapper" {{action "clickConv" conv preventDefault=false}}>
<div class="history-message-assigned in-progress-closed" style="display:none;"><p><i class="icon-x"></i>Conversation closed</p></div>
<div class="history-message-assigned in-progress-assignation" style="display:none;"><p><i class="icon-assign"></i>Conversation assigned</p></div>
<div class="history-message-assigned in-progress-reopen" style="display:none;"><p><i class="icon-re-opened"></i>Conversation re-opened</p></div>
<div class={{conv.selectedClass}}>
<div class="conversation-time-history">{{{conv.status}}}</div>
<div class="conversation-details">
<span class="unread-numbers"></span>
{{input type='checkbox' class='chk-conversation' checked=conv.isChecked}}
<span class="conversation-name">{{conv.customer.name}}</span>
<span class="phone-number">{{conv.customer.cellPhoneNumber}}</span>
<p class="conversation-text">{{conv.lastMessage}}</p>
</div>
</div>
</div>
{{/if}}
and then the "for-each" block
{{#each conv in model itemController='singleconv'}}
{{the-component conv=conv}}
{{/each}}
Then use a counter or something to make the first 10 visible.
As I said this is only a simple example you can dig more into it.
I'm new to Ember, I want to add some query DOM manipulation code to the element in the {{#each}} block. So I google it up and found the solution from this guide:
views/products/index.js
import Spinner from 'appkit/utils/someJqueryCode';
Ember.View.reopen({
didInsertElement : function(){
this._super();
Ember.run.scheduleOnce('afterRender', this, this.afterRenderEvent);
},
afterRenderEvent : function(){
// implement this hook in your own subclasses and run your jQuery logic there
}
});
export default Ember.View.extend({
afterRenderEvent: function() {
Spinner();
}
});
templates/products/index.hbs
<div class='panel panel-default products'>
<div class='panel-heading'>
<h2 class='panel-title'>Our Prodcuts</h2>
</div>
<div class='panel-body'>
<ul class='row'>
{{#each}}
<li class='col-md-4'>
<div class='thumbnail'>
<img {{bind-attr src=url alt=alt}} />
</div>
<div class='caption'>
<h3 class='name-me'>{{name}}</h3>
<p>{{description}}</p>
<div class='row no-gutter'>
<div class='col-xs-3'>
<button class='btn btn-primary'>Buy</button>
</div>
</div>
</div>
</li>
{{/each}}
</li>
</div>
</div>
But I seems after the point when afterRenderEvent() is triggered, all the elements in the {{#each}} block hasn't been rendered to the DOM yet, thus, the jQuery code return undefined
What's the right way to do it?
Your view's didInsertElement hook will fire as soon as the application route is rendered, which happens before the index route. You might think that putting it in the index.js file will work, but it's going to just extend the default application view behavior.
You need to create a more focused view that lives within your index.hbs file. One that is only concerned with your spinner jQuery doohickey. That, and an each/else conditional could work nicely here. For example:
{{#each}}
{{#view App.SpinnerDoohickeyView}}
<li class='col-md-4'>
<div class='thumbnail'>
<img {{bind-attr src=url alt=alt}} />
</div>
<div class='caption'>
<h3 class='name-me'>{{name}}</h3>
<p>{{description}}</p>
<div class='row no-gutter'>
<div class='col-xs-3'>
<button class='btn btn-primary'>Buy</button>
</div>
</div>
</div>
</li>
{{/view}}
{{else}}
<li>Empty collection!</li>
{{/each}}
Notice that I've wrapped each list item in its own view. You could wrap the whole ul if you wanted... this is just an example. The idea is that you are only creating views when you have a model.
And now you can define the view, and simply use the didInsertElement hook to work with jQuery:
App.SpinnerDoohickeyView = Ember.View.extend({
didInsertElement: function () {
this.$('li').css('background', 'blue');
}
});
If you have a model to render, jQuery should be able to safely access it this way. Good luck!
Here's some further reading and some code from the Ember folks that looks like what I've shown you here: http://emberjs.com/guides/views/handling-events/
Considering the following:
Parent template:
{{view App.SomeView id="42" panelClass="default"}}
View template:
<div class="col-md-3 col-sm-6">
<div class="panel panel-{{panelClass}}">
<div class="panel-heading">
<h3 class="panel-title">
{{name}}
</h3>
</div>
<div class="panel-body">
{{description}}
</div>
</div>
</div>
View JS:
App.SomeView = Ember.View.extend({
templateName: 'views/some-view'
});
How can I achieve output HTML where the panel class gets set properly? At the moment it doesn't work because it wants to bind, so it inserts the ember metamorph script tags, instead of just plain text for the panel class.
Also, the template is wrapped in an extra div. How would I modify it so that the ember-view wrapping div is actually the first div in the template (the one with col-md-3 col-sm-6)?
The bind-attr helper exists for that reason. Here's the guide entry.
<div {{bind-attr class=":panel panelClass"}}></div>
Also, not sure if you can use a prefix on panelClass in the template. If might be easier just to use a computed property to add the panel- beforehand.
I'm sorry, I didn't see your second question about the extra div. The guide explains here how to extend the element.
App.SomeView = Ember.View.extend({
classNames: ['col-md-3', 'col-sm-6']
});

I am having a weird problem rendering CSS under Ember.js. It is weird because the just works fine after manually refreshing the page, and in plain HTML without Ember. I have tried different browsers and different CSS libraries and all the same.
I just want to render tabs inside a handlebars template, I have tried both Zurb Foundation sections and jQuery-ui tabs and both work only after manual page refresh.
I have tried to reproduce the problem with JSBin but it didn't work. I am using the example code from both libraries to do this.
Here is my HTML with Zurb Foundation 4.3: (referencing js and css libraries omitted for brevity)
<html>
<body>
<script type="text/x-handlebars">
<nav class="top-bar" data-options="is_hover=false">
<ul class="title-area">
<li class="name">
<h1>Main</h1>
</li>
<li class="toggle-topbar menu-icon"><span>Menu</span></li>
</ul>
<section class="top-bar-section">
<ul class="left show-on-small">
<li>{{#linkTo 'families'}}Families{{/linkTo}}</li>
</ul>
<ul class="left">
<li>{{#linkTo 'charities'}}Charities{{/linkTo}}</li>
</ul>
</section>
</nav>
<div>
{{outlet}}
</div>
</script>
<script type="text/x-handlebars" data-template-name="families">
<div class="row display">
<div class="large-3 columns">
<span>{{#linkTo 'families.details'}}list{{/linkTo}}</span>
</div>
<div class="large-9 columns">
{{outlet}}
</div>
</div>
</script>
<script type="text/x-handlebars" data-template-name="families/details">
<div class="row">
<span>details</span>
</div>
<div class="row">
<section class="section-container auto" data-section data-section-small-style>
<section class="active" >
<p class="title" data-section-title>Family Info</p>
<div class="content" id="panel1" data-section-content>
<span>Family Info goes here</span>
</div>
</section>
<section>
<p class="title" data-section-title>Members</p>
<div class="content" data-slug="panel2" data-section-content>
<span>Family members list goes here</span>
</div>
</section>
</section>
</div>
</script>
</body>
</html>
My Javascript:
App = Em.Application.create();
App.Router.map(function() {
this.resource('families', function() {
this.route('details');
});
this.resource('charities');
});
Just wanted to know if there are any known issues or caveats between Ember/handlebars and CSS.
Thank you.
EDIT: Got a sample running at http://jsbin.com/iTOsof/3 but does not work after refresh like local host
I am guessing the reason it's not working is because Foundations JavaScript handler is being run when the DOM fires its ready event, at that point Ember haven't rendered its templates so there's nothing to tie the tabs to.
What you could try to do is to add $(document).foundation(); to the DetailsViews didInsertElement.
App.DetailsView = Ember.View.extend({
didInsertElement: function() {
$(document).foundation('section'); // this will only load the section component
}
});
One issue though, since Foundation's JavaScript components are not compatible with Ember you will most likely run into problems when Foundation appends their location hash for the selected section since Ember is using the same method to handle its routing.
You can change Embers location method to a modern variant by specifying:
App.Router.reopen({
location: 'history'
});
This will however not be compatible with IE 9 and below.
Another alternative is to use Bootstrap as an alternative to Foundation (personally I prefer Foundation over Bootstrap but in this case it may be worth it if you don't want to create your own components in Ember), and then use the Ember Components made available for Bootstrap, http://ember-addons.github.io/bootstrap-for-ember/dist/#/show_components/tabs-panes
Using ember 1.0.0-pre3
I have a little app that has this code:
window.App = Ember.Application.create()
App.ApplicationController = Ember.Controller.extend({})
App.Router.reopen
location: 'history'
App.Router.map ->
#resource 'users', ->
#route 'new'
App.IndexRoute = Ember.Route.extend
renderTemplate: ->
#render('index')
This is application.hbs in the templates directory:
<div class='navbar navbar-inverse navbar-fixed-top'>
<div class='navbar-inner'>
<div class='container'>
<div class='nav-collapse collapse'>
<ul class='nav'>
<li>{{#linkTo 'index'}}Home{{/linkTo}}</li>
<li>{{#linkTo 'users.index'}}Users{{/linkTo}}</li>
</ul>
</div>
</div>
</div>
</div>
<div class='container' id='main'>
<div class='content'>
<div class='row'>
<div class='span12'>
<div class='page-header'></div>
{{outlet}}
</div>
</div>
</div>
</div>
The problem is that it doesn't render this template. It doesn't throw an error when loading the the app at the base url "http://127.0.0.1:3000/". It will throw an error if I try an undefined route, so I know that Ember is loaded.
There does not appear to be anything wrong with your ember code. I made a copy on jsbin and it works fine: http://jsbin.com/ipivoz/1/edit
Pretty sure that means your template is not being compiled. To be sure, try adding the following to your application ready hook:
window.App = Ember.Application.create({
ready: function() {
console.log("Ember.TEMPLATES: ", Ember.TEMPLATES);
}
});
Ember expects compiled handlebars templates to be in this array. If you run the above jsbin with js console open you'll see there is one template 'application' in the array. My guess is that the array will be empty if you try the same in your environment.
There are many ways to get that done, which is right depends on your environment. Since you're running on port 3000 I'm gonna guess that's rails. In that case check out the ember-rails gem. By far the simplest short-term approach is to define templates using script tags within the HTML page, as I've done in the jsbin.
