Ember js version 1: Route hierarchy / activation - ember.js

We have a scenario along these lines:
Quote
--->Create
So route names quote and quote.create.
The issue is that we need to render the templates into the main outlet. So in our main route (that all other are inherited from) we have this:
renderTemplate: function() {
this.render({ into: 'application' });
}
When I navigate to quote it renders the quote view. From there I navigate to quote.create and it renders the create view. However, going back to quote from quote.create renders nothing.
How can I get around this?
When I go back to the \quote url route 'quote.index' is sought. Since it is defined 'automagically' nothing happens. When I define the route explicitly ember tries to find the quote.index template and view and these do not exist.
A workaround I tried is to have this:
App.QuoteIndex{Route|Controller|View} = App.Quote{Route|Controller|View}.extend()
EDIT:
Hey diddle-diddle, here is my fiddle :) http://jsfiddle.net/EbenRoux/Mf5Dj/2/

Ember.js does not rerender a parent view when transitioning to a parent route, so using into with a parent view template is not recommended.
There is an easier way to create what you are trying to: use a quote/index route:
<script type="text/x-handlebars" data-template-name="application">
<h1>Rendering Issue</h1>
{{outlet}}
</script>
<script type="text/x-handlebars" data-template-name="quote">
{{outlet}}
</script>
<script type="text/x-handlebars" data-template-name="quote/index">
<h2>Quote View</h2>
{{#linkTo 'quote.create'}}Create a new quote{{/linkTo}}
</script>
<script type="text/x-handlebars" data-template-name="quote/create">
<h2>Quote Create View</h2>
<p>Some controls would go here.</p>
{{#linkTo 'quote'}}Go back to quote view{{/linkTo}}
</script>
App = Ember.Application.create({});
App.ApplicationRoute = Ember.Route.extend({
activate: function () {
this.transitionTo('quote');
}
});
App.Router.map(function () {
this.resource('quote', function () {
this.route('create');
});
});

Inheriting singular controller with render helper

I am trying to render a set of tabs for a set of objects (conversations) using the render helper for each. This is not part of a route as it is a persistent part of the interface. I have run into a problem where only the view with the same name as the model gets the intended controller (i.e. the panel contents and not the tab headers).
I have a Chat model, object controller and array controller (deliberately simplified here):
App.Chat = DS.Model.extend({ });
App.ChatsController = Ember.ArrayController.extend({
needs: 'application',
content: Ember.computed.alias('controllers.application.currentChats'),
});
App.ChatController = Ember.ObjectController.extend({ });
The ArrayController needed the needs/content properties because the chats are loaded in the application controller. I used the currentChats name as other routes may load non-current chats.
App.ApplicationController = Ember.Controller.extend({
init: function(){
this.store.find('chat', {"current": true});
this.set('currentChats', this.store.all('chat'));
}
});
I have no difficulty rendering the chat contents with the appropriate controller (into the 'chat' template). However, the chat tabs are given the default ObjectController, and therefore can't fire actions.
<script type="text/x-handlebars" id="application">
<!--application template-->
{{outlet chats}}
</script>
<script type="text/x-handlebars" id="chats">
<div id="chats">
<ul id="chat-tabs">
{{#each}}
{{render 'chatTab' this}}
{{/each}}
</ul>
{{#each}}
{{render 'chat' this}}
{{/each}}
</div>
</script>
<script type="text/x-handlebars" id="chatTab">
<!--tab template-->
</script>
<script type="text/x-handlebars" id="chat">
<!--chat template-->
</script>
The application router is as follows:
App.ApplicationRoute = Ember.Route.extend({
model: function(){ },
renderTemplate: function(){
this.render('application', { });
this.render('chats', {
into: 'application',
outlet: 'chats',
controller: 'chats'
});
}
});
This seems to come solely down to naming of the templates. The template called 'chat' inherits the correct controller, but chatTab doesn't despite receiving a chat as the model. Is there any way to force the view to inherit the correct controller? Or am I going about this in an idiosyncratic way.
Many thanks for your help to this Ember novice.
Andrew
It goes solely off the name provided to the render. The easiest way is to just create the other controller and extend the chat controller.
App.ChatTabController = App.ChatController.extend();

How to have an element load with the application in Ember.js

I am trying to create my first ember application but I can't have a template load with the application template:
Below is a simplified version of my layout:
<script type="text/x-handlebars">
{{outlet}}
</script>
How do I get the another template into the outlet section on page load?
Thanks in advance
For example if my second template is:
<script type="text/x-handlebars" id="yellow">
<p>Something</p>
</script>
#Marcio answer is correct, ember does create an implicit index route.
However the most important part here is that if you have, say a route like yellow that you want to be rendered inside the application's {{outlet}} (instead of the implicit index template) then you need to define a path for that route so the correspondent named template, (in your case yellow) will be rendered into the application's {{outlet}} instead of the implicit index:
App.Router.map(function() {
this.route('yellow', {path: '/'})
});
<script type="text/x-handlebars" data-template-name="application">
<h1>Hi</h1>
{{outlet}}
</script>
<script type="text/x-handlebars" data-template-name="yellow">
<h2>Welcome from yellow</h2>
</script>
If you don't do this then ember will search for an index template to be rendered inside the outlet, and since you doesn't have one, nothing will be displayed. So again, by defining a path like "/" for your yellow route you instruct ember to use the yellow template instead of the index.
Of course, if you rename your yellow template to index then it will be picked up by ember and rendered inside the application outlet and you don't need to specify a path for the yellow route.
Example jsfiddle.
Hope it helps.
When you create a route like this:
App.Router.map(function() {
this.route('yellow')
});
and a transition is performed to yellow route.
For example, via {{#link-to 'yellow'}}Yellow{{/link-to}} or changing the url tohttp://www.yourhost.com#/yellow`
A handlebar template is appended in the dom, with the same name like the route:
<script type="text/x-handlebars" id="yellow">
<p>Something</p>
</script>
By default ember create a route('index') in your router mapping, like this:
App.Router.map(function() {
this.route('yellow')
// this.route('index', { path: '/' })
});
So creating a index template will work
<script type="text/x-handlebars" id="index">
Welcome
</script>
When the user navigate to the url http://www.yourhost.com, he will see Welcome.

Ember: controller properties not available in partial views - what am I doing wrong?

See JSFiddle: http://jsfiddle.net/cyclomarc/aYmuJ/3/
I set a property in the application controller and want to display this property in a partial view. This does not seem to work. I can access the property in the template itself, but not in the partial view rendered within the template ..
index.html
<script type="text/x-handlebars">
<h3>Ember access to controller properties</h3>
{{#linkTo 'about'}}About{{/linkTo}} <br><br>
{{outlet}}
</script>
<script type="text/x-handlebars" data-template-name="about">
Access to property in index template: <br>
<b>{{controllers.application.applicationVersion}}</b>
<br><br>
{{render "_footer"}}
</script>
<script type="text/x-handlebars" data-template-name="_footer">
Footer text (partial view) with a controller property:<br>
<b>{{controllers.application.applicationVersion}} MISSING</b>
</script>
app.js
var App = Ember.Application.create({});
App.Router.map(function () {
this.resource('about', { path: "/about" });
});
App.IndexRoute = Ember.Route.extend({
redirect: function () {
this.transitionTo('about');
}
});
App.ApplicationController = Ember.Controller.extend({
//Set some properties
applicationVersion: "1.0.0"
});
App.AboutController = Ember.Controller.extend({
needs: "application"
});
render view helper have your own context.
To use the current context in a other template use the partial view helper.
{{partial "footer"}}
When you use render a new controller is created, in that case named generated _footer controller.
Using partial will preserve the controller bound to the template that called the partial template
And since you used needs in about controller, you don't have it in the new generated controller.
Here is a sample

Ember pre4 - nested routes

I'm trying to understand how to use nested routes.
My code:
App.Router.map(function() {
this.route("site", { path: "/" });
this.route("about", { path: "/about" });
this.resource("team", {path:'/team'}, function(){
this.resource('bob',{path:'/bob'});
});
});
And I'm trying to get to the Bob page with:
{{#linkTo 'bob'}}bob{{/linkTo}}
What am I missing?
jsbin
Thanks.
try instead
{{#linkTo 'team.bob'}}bob{{/linkTo}}
Between you can simplify your router map this way - you only need to specify the path if it's different from the route name.
App.Router.map(function() {
this.route("site", { path: "/" });
this.route("about");
this.resource("team", function(){
this.route('bob');
});
});
UPDATE
See a working example here
In summary, You need to provide an implementation of the renderTemplate function of TeamBobRoute where you explicitly specify where you want to render your template bob. Using the render option into you can override the default behaviour, rendering to the parent outlet, and pick which parent template to render to
App.TeamBobRoute = Ember.Route.extend({
renderTemplate:function(){
this.render('bob',{
into:'application',
});
}
});
<script type="text/x-handlebars" data-template-name="site-template">
This is the site template
{{#linkTo 'about'}}about{{/linkTo}}
{{#linkTo 'team'}}team{{/linkTo}}
</script>
<script type="text/x-handlebars" data-template-name="about">
This is the about page
</script>
<script type="text/x-handlebars" data-template-name="team">
This is the team page
{{#linkTo 'team.bob'}}bob{{/linkTo}}
</script>
<script type="text/x-handlebars" data-template-name="bob">
This is the bob page
</script>
<script type="text/x-handlebars">
This is the application template
{{outlet}}
</script>
FYI the render method supports the following options: into, outlet and controller as described below.
The name of the PostRoute, as defined by the router, is post.
By default, render will:
render the post template
with the post view (PostView) for event handling, if one exists
and the post controller (PostController), if one exists
into the main outlet of the application template
You can override this behavior:
App.PostRoute = App.Route.extend({
renderTemplate: function() {
this.render('myPost', { // the template to render
into: 'index', // the template to render into
outlet: 'detail', // the name of the outlet in that template
controller: 'blogPost' // the controller to use for the template
});
}
});
If you had a named template inside your application template then you would target it this way
App.TeamBobRoute = Ember.Route.extend({
renderTemplate:function(){
this.render('bob',{
into:'application',
outlet:'team-member',
});
}
});
<script type="text/x-handlebars">
This is the application template
{{outlet 'team-member'}}
{{outlet}}
</script>
You're missing the outlet in the team page. The template should look like this.
<script type="text/x-handlebars" data-template-name="team">
This is the team page
{{#linkTo 'bob'}}bob{{/linkTo}}
{{outlet}}
</script>
Each route is rendered into it's parent's template's outlet.
so when you go into "team", then "team" is rendered into the "application" outlet.
When you go to "bob", the "bob" template is rendered into the "team" outlet.
This can be overridden, but is the default behavior.
Also, each parent resources gives you two model/controller/view/template sets. So when you define:
this.resource('team',{path:'/team'});
You get the "team" template and the "team-index" template.
the "team" template is where stuff that is shared between child routes goes (this is why it needs to have the outlet) and the "team-index" template is where stuff that is specific to your "team index" would go.

How to render multiple templates for a route in Router v2

my index template has two outlets, one for header, another for content. the template rendered in the content changes depending on the content being viewed.
In the old router, this could be done by calling connectOutlet on different controllers who owned that template. I can't figure out how to do the same in the new router.
any suggestions?
With my research, I came to this:
Say you have a router defined like this:
App.Router.map(function(match) {
match('/').to('index');
});
ApplicationTemplate:
<script type="text/x-handlebars">
{{outlet header}}
{{outlet}}
</script>
IndexTemplate:
<script type="text/x-handlebars" data-template-name="index">
{{outlet dashboard}}
{{outlet spaces}}
</script>
Now, What we want is that when user goes to the index router, the page should:
Render index into main outlet and header into header outlet of application template.
render dashboard, spaces template into Index Template.
To achieve this, we write the following code in indexRoute
App.IndexRoute = Em.Route.extend({
renderTemplate: function(controller, model){
//Render header into header outlet
this.render('header',{
outlet:'header'
});
//Render index into main outlet. If you comment out
//this line, the code below fails
this.render('index');
//by using into, we can render into the index template
//Note: The controller is optional.if not specified,
//ember picks up controller for the given template.
this.render('dashboard',{
outlet:'dashboard',
into:'index',
controller:this.controllerFor('somethingElse', App.TestModel.find())
});
//controller is SpacesController
this.render('spaces',{
outlet:'spaces',
into:'index'
});
}
});
you can use the renderTemplates function in the router to render mulitple views to name outlets:
renderTemplates:function () {
this.render('todos_list', {
into:'todos', //template name
outlet: 'todos', //named outlet
controller: 'listController' //controller you want to use
});
this.render('todos_test', {
into:'todos',
outlet: 'test',
controller: 'testController'
});
},
setupControllers:function (controller, model) {
this.controllerFor('list').set('content', listmodel.find());
this.controllerFor('test').set('content', testmodel.find());
}
The setupControllerControllerFor function will allow you to assign what we set as 'context' in the previous router.
In your template, you would name outlets just as before:
{{outlet list}}
{{outlet test}}
Hope this helps :)
