Index Route vs Custom Route causes application.hbs model issues - ember.js

I am working with Ember 2.9, and I'm facing a weird routing + model issue.
I have two routes that are identical (copied and pasted code inside the route) except for the pathing. I have one route which is '/', and another route which is 'my-route'.
import Ember from 'ember';
export default Ember.Route.extend({
model() {
let dict = {
myLog1Model: this.get('store').findAll('my-log1'),
myLog2Model: this.get('store').findAll('my-log2'),
myLog3Model: this.get('store').findAll('my-log3'),
myLog4Model: this.get('store').findAll('my-log4')
};
return dict;
}
});
When I access my ember application from localhost/ all model data is displayed properly, but when I access it from localhost/my-route none of the model data is being passed around in application.hbs
application.hbs
<section class='container-fluid'>
<div class='row'>
<div class='col-md-6'>
{{control-panel model=model}}
</div>
<div class='col-md-6'>
{{log-panel model=model}}
</div>
</div>
</section>
log-panel.hbs
{{myLog1 model=model.myLog1Model}}
{{myLog2 model=model.myLog2Model}}
{{myLog3 model=model.myLog3Model}}
{{myLog4 model=model.myLog4Model}}
Ember tables takes it from here...
myLog1.hbs
{{models-table
data=model
columns=columns
useNumericPagination=true}}
As I stated before this works perfectly fine with 'localhost/', but not with 'localhost/my-route'. Any idea why this is?

I was able to resolve my issue, by loading any application model data in the Application Route. I had no idea that there was a difference between '/', and the application route.

EmberJS show router model in application.hbs

I am working with Ember.js, and I am trying to make my pages display the title of the page just below the navbar. To make this work I have tried to use model hook, and show it in the application.hbs file.
So far I have tried variations of this:
routes/contact.js
import Route from '#ember/routing/route';
export default class ContactRoute extends Route {
model() {
return 'Title of page';
}
}
templates/application.hbs
<div>
<NavBar />
<div class="pageTitle">
<h2>
<p>{{#model}}</p>
</h2>
</div>
<div class="body">
{{outlet}}
</div>
</div>
I've mostly tried to mess around with #model in application.hbs things like outlet.#model. But all of these attempts have resulted in empty titles or Template Compiler Errors.
Does anyone have a solution for this? Preferably one that does not involve jquery?
If I understand correctly what you are trying to accomplish, it is a good use case for services.
You need a couple parts. A service to keep track of the page title, and then you need to inject that service in the application controller so the template has access to the service, and also to inject the page title service in the routes so you can update the page title in the respective hooks.
Page service
import Service from '#ember/service';
import { tracked } from '#glimmer/tracking';
export default class extends Service {
#tracked title = "Your App"
}
Application controller and template
import Controller from '#ember/controller';
import { inject as service } from '#ember/service';
export default class ApplicationController extends Controller {
#service pageTitle;
}
<h1>Welcome to {{this.pageTitle.title}}</h1>
<br>
<br>
{{outlet}}
<LinkTo #route="my-route">my route</LinkTo>
<br>
<br>
MyRoute route updating the page title value in a model hook
import Route from '#ember/routing/route';
import { inject as service } from '#ember/service';
export default class extends Route {
#service pageTitle;
model() {
this.pageTitle.title = "My Route"
}
}
I have put it all together in an interactive Ember Twiddle demo.
Hope this helps!
Since you have created a new page (route) named contact, the UI part of the page has to be in the corresponding template file, i.e., templates/contact.hbs and not templates/application.hbs as the templates/contact.hbs file can only access the #model of routes/contact.js
ie., the below markup has to in templates/contact.hbs file and will be displayed when accessing the page at http://localhost:4200/contact
<div class="pageTitle">
<h2>
<p>{{#model}}</p>
</h2>
</div>
Also, note that the markup present in the templates/contact.hbs file will be rendered in the place of application template's {{outlet}} (see here)

How to create action for my own component

I am creating one ember app.
Flow is like " page1 displays list of feeds item and clicking on any of the feed will take user to page2 showing details about that feed"
What i am doing:
i have one component named app-feed. Template is as below
<div onclick={{action 'click' feed}}>
{{#paper-card class="card-small" as |card|}}
<!-- --> {{card.image src=feed.imagePath class="small-feed-img" alt=feed.title}}<!---->
{{#card.header class="flex-box short-padding" as |header|}}
{{#header.avatar}}
<img class="profile-small" src="http://app.com/users/{{feed.userName}}.jpg" alt="{{feed.name}}" />
{{/header.avatar}}
<span class="tag-sm like-box">
{{feed.likes}} {{paper-icon "thumb_up" size="18"}}
{{feed.commentCount}}{{paper-icon "chat_bubble" size="18"}}
</span>
{{/card.header}}
{{#card.actions class="action-block"}}
{{#paper-button iconButton=true}}{{paper-icon "favorite" size="18"}}{{/paper-button}}
{{#paper-button iconButton=true}}{{paper-icon "share" size="18"}}{{/paper-button}}
{{#paper-button iconButton=true}}{{paper-icon "shopping_basket" size="18"}}{{/paper-button}}
{{/card.actions}}
{{/paper-card}}
</div>
component.js is as below
import Ember from 'ember';
export default Ember.Component.extend({
actions:{
click(feed){
console.log("Click event fired:"+feed.id); //Output is correct in console
this.sendAction("onClick", feed); //sending onClick Action
}
}
});
I'm populating list of this component in one of my route.
Template is as below
{{#app-sidenav user=model}}{{/app-sidenav}}
<div class="content">
<div class="row">
{{#each model as |item|}}
{{#app-feed-small onClick=(action "getDetail" item) class="col-xs-5" feed=item}} {{/app-feed-small}}
{{/each}}
</div>
</div>
route.js is as below
import Ember from 'ember';
export default Ember.Route.extend({
store: Ember.inject.service(),
model(){
//Populating module. Works just fine
} ,
actions:{
getDetails(feed){
console.log("Getting details of "+feed.id);
}
}
});
I have defined getDetails action as mentioned in my template.js of the route still i am getting below error
""Assertion Failed: An action named 'getDetail' was not found in (generated feed.index controller)""
feed.index is my route.
I used same method and modified paper-chip's source to get action corresponding to click on paper-chip's item which worked. But i am not able to do same in my own component.
Please let me know what is missing
Your problem is that in your second last code snippet, the one with your template. You refer to the action as getDetail but in route.js your last code snippet you declare the action as getDetails which is different to the code in your template. It's a common spelling error, one has an "s" st the end whereas the other doesn't.
The actions should be in controllers. And if controller bubbles up then the action in route be called.
For your case you don't need controller.
You can use ember-transition-helper
I assume you have in router.js :
this.route('feeds', function(){
this.route('edit', {path: '/:id'});
});
Now your template is going to be :
{#app-sidenav user=model}}{{/app-sidenav}}
<div class="content">
<div class="row">
{{#each model as |item|}}
{{#app-feed-small onClick=(transition-to "feeds.edit" item) class="col-xs-5" feed=item}} {{/app-feed-small}}
{{/each}}
</div>
</div>
sendAction is an ancient way to calling action inside controller/route.
The new style is to use closure action, which passes action as a value by creating a closure at the time of value passing.
Yes, you are correct. The action has been sendAction is able to bubble up from,
correspond controller -> correspond route -> upper route -> ... -> application route
However, closure action does NOT bubble.
Please refer to Ember component send action to route where #kumkanillam detailed explained how to call action inside route using different method and the differences between sendAction and closure action.
I have also made a sample project and write a simple explanation for it at,
https://github.com/li-xinyang/FE_Ember_Closure_Action

Controlling component data across multiple routes

I have a mapping app that has a full-screen map with a sidebar for information. This app has two routes:
one route that should display a list of places with markers on the map, for example /places/
one route that should display a single place with that particular place's marker centered on the map, for example places/1/
My map is currently a Component that is in application.hbs, so it is "outside" of the route templates and persists across route changes. It looks something like:
<div class="page">
<aside class="sidebar">
{{outlet}}
</aside>
<div class="content">
{{places-map ... }}
</div>
</div>
and my routes looks something like:
Router.map(function() {
this.route('index', { path: '/' });
this.route('place', { path: "/place/:place_id" });
this.route('places');
});
So while I have all this set up and working (I can see a list of places and move a single particular place, in both cases with the map in the "background"), I can't understand how my routes can feed information to my component or simply how my routes can communicate with the component that is sitting "outside" of their context?
Is this a possible pattern with Ember and is there a way to achieve it?
Ditto on what #GerDner said about data-down-actions-up.
Starting from the top:
application/controller.js
import Ember from 'ember';
export default Ember.Controller.extend({
somethingDownFromController: null
});
application/route.js
import Ember from 'ember';
const {
set
} = Ember;
export default Ember.Route.extend({
actions: {
sendSomethingUp(something) {
set(this.controllerFor('application'), 'somethingDownFromController', something);
}
}
});
application/template.hbs
<div class="page">
<aside class="sidebar">
{{outlet}}
</aside>
<div class="content">
{{places-map
something=somethingDownFromController
}}
</div>
</div>
place/route.js
import Ember from 'ember';
export default Ember.Route.extend({
model() {
return {
somethingFromNestedRoute: 'boooooyaaaaah'
}
}
});
place/template.hbs
<button {{action 'sendSomethingUp' model.somethingFromNestedRoute}}>
Send model up
</button>
You might not need to send anything up with the action you're bubbling here. If that's the case then you can just grab what you need from the application controller or route and pass it down into places-map.
places-map/template.hbs
Insert something from the outer context:
<div>{{something}}</div>
Here's an ember-twiddle. I made a few notes in the router.js file that might be useful depending on the exact needs of your application.
The data-down/actions-up Pattern is the answer.
http://www.samselikoff.com/blog/data-down-actions-up/
You hold the data on a toplevel component/controller and pass the data down to child components. Data changes are triggered via actions on the child component and handled by the toplevel component/controller via action bubbling. So you need only one component/controller which knows how to change the data and how to get data.

Ember - Set a Dynamic Page Title per route

I have set up my Ember app to use the pod structure. I've created a topbar-nav component which I display on the main page. In the topbar-nav component I have set up the page title, which I would like to set automatically per route so for the dashboard route the title should be Dashboard, for the dashboard/categories the title should be categories and so on.
Here's my app structure:
app
application
components
topbar-nav
dashboard
categories
The app router - router.js
import Ember from 'ember';
import config from './config/environment';
var Router = Ember.Router.extend({
location: config.locationType
});
Router.map(function() {
this.route('dashboard', function() {
this.route('categories');
});
});
export default Router;
And the templates:
application/template.hbs
<aside>
{{sidebar-nav}}
</aside>
<main>
<header>
{{topbar-nav}}
</header>
{{outlet}}
</main>
components/topbar-nav/template.hbs
<nav class="topbar-nav">
<div class="text-center">
<h5 class="page-title">{{title}}</h5>
</div>
</nav>
{{yield}}
components/topbar-nav/component.js
import Ember from 'ember';
export default Ember.Component.extend({
title: 'Component title'
});
As you can tell already the title I get rendered is 'Component title'
The most accurate answer I got by now is this one:
Ember dynamic titles
though after trying a lot of different approaches I couldn't find a good solution.
Is there a clean and easy way of doing this? Any ideas and solutions are much appreciated.
I wanted a similar dynamic title and found this page. So here is my solution based on #AcidBurn's note that the application controller has a currentRouteName property.
If you want the last child route:
screen_title: Ember.computed('currentRouteName', function () {
let route = this.get('currentRouteName').split('.');
// Return last route name (e.g. categories from dashboard.categories)
return route[route.length - 1];
}),
If you want the parent route:
screen_title: Ember.computed('currentRouteName', function () {
let route = this.get('currentRouteName').split('.');
// Return parent route name (e.g. reports from reports.index)
return route[0];
}),
ember-page-title seems better than ember-cli-document-title now (better docs+api)

Understand routing in Ember.js

I'm really struggling to understand the routing concept in Ember but is more complicate than what it seem. From the doc. you can see you have different route whenever there is different url or path and if you have different path in the same url, easy you just need to create a nested template.
But what about when you have 3 different path in one url?
And what's the difference from this.resource and this.route?
Since live example are always better than pure theory, here my app.
In index or '/' I should render "list template", "new template" and when user click on a list link, the "note template" is render instead "new template".
My router:
Notes.Router.map(function () {
this.resource('index', { path: '/' }, function (){
this.resource('list', {path: ':note_title'});
this.resource('new', {path: '/'});
this.resource('note', { path: ':note_id' });
});
});
My template:
<script type="text/x-handlebars" data-template-name="index">
<div class="wrap">
<div class="bar">
{{input type="text" class="search" placeholder="Where is my bookmark??" value=search action="query"}}
<div class="bar-buttons">
<button {{action "addNote"}}> NEW </button>
</div>
</div>
{{outlet}}
</div>
</script>
<script type="text/x-handlebars" data-template-name="list">
<aside>
<h4 class="all-notes">All Notes {{length}}</h4>
{{#each item in model}}
<li>
{{#link-to 'note' item}} {{item.title}} {{/link-to}}
</li>
{{/each}}
</aside>
</script>
<script type="text/x-handlebars" data-template-name="new">
<section>
<div class="note">
{{input type="text" placeholder="Title" value=newTitle action="createNote"}}
<div class="error" id="error" style="display:none"> Fill in the Title! </div>
{{input type="text" placeholder="What you need to remember?" value=newBody action="createNote"}}
{{input type="text" placeholder="Url:" value=newUrl action="createNote"}}
</div>
</section>
</script>
<script type="text/x-handlebars" data-template-name="note">
<section>
<div class="note">
{{#if isEditing}}
<h2 class="note-title input-title"> {{edit-input-note value=title focus-out="modified" insert-newline="modified"}} </h2>
<p class="input-body"> {{edit-area-note value=body focus-out="modified" insert-newline="modified"}} </p>
{{edit-input-note value=url focus-out="modified" insert-newline="modified"}}
{{else}}
<h2 {{action "editNote" on="doubleClick"}} class="note-title" > {{title}} </h2>
<button {{action "removeNote"}} class="delete"> Delete </button>
<p {{action "editNote" on="doubleClick"}}> {{body}} </p>
{{input type="text" placeholder="URL:" class="input" value=url }}
{{/if}}
</div>
</section>
</script>
Or here the Js Bin: http://jsbin.com/oWeLuvo/1/edit?html,js,output
If my controllers or model are needed I will add that code as well.
thanks in advance
Your example seems to be working.
You just miss dependencies. You haven't included Handlebars and Ember.data
If you'd have checked your javascript console, you'd have seen the error thrown.
working example: http://jsbin.com/oWeLuvo/2/
In Ember a resource and a route are both routes. They have two names in order for Ember to differentiate between what is a resource and a route. In all honesty to remember that they are both routes and to keep your sanity you could refer to them respectively as a 'resource route' and a 'route'. A resource can be nested and have children resources or routes nested within them. Routes on the other hand cannot have nested anything.
Install the Ember Inspector if you are not already using it. It is a chrome extension and will help you with routes, controllers, templates, data and alot of other things with Ember, that you install into the Chrome Web Browser. The last that I heard the Ember Inspector is available in the FireFox Dev Tools as well. https://chrome.google.com/webstore/detail/ember-inspector/bmdblncegkenkacieihfhpjfppoconhi?hl=en
So if have a resource, you can nest a resource, and a route. The nested resources will preserve their name space, routes will get appended to nested name space. Remember you can not nest anything within a route.
App.Router.map(function() {
//creating a resource
this.resource('foo', {path: 'somePathYouPut'}, function() {
//nesting stuff inside of the resource above
//could open another nest level here in bar if you want
this.resource('bar');
//can not nest in route. Sad face. Sorry
this.route('zoo');
});
});
Since you can not nest anything into a route your {{outlet}} in the index template does not have any children to look for and by default and render into that {{outlet}}. I believe that is what you think is going to happen.
<script type="text/x-handlebars" data-template-name="index">
<div class="wrap">
<div class="bar">
{{input type="text" class="search"
placeholder="Where is my bookmark??" value=search action="query"}}
<div class="bar-buttons">
<button {{action "addNote"}}> NEW </button>
</div>
</div>
{{outlet}}
</div>
</script>
In your code you referred to the index as a resource, its a route. Since the index is a route, remember you can not nest elements within a route, your code should have looked more like this. Also your resource 'new' path / can be removed as well.
Notes.Router.map(function () {
//this is a route not a resource you had it as resource
//and tried to nest in your code
this.route('index', { path: '/' });
this.resource('list', {path: ':note_title'});
this.resource('new');
this.resource('note', { path: ':note_id' });
});
You get an index at each nested level starting with the top most level which comes from the application level but you don't have to explicitly define them in the Router they are just there. The index route that you get for free at each nested level is associated with its immediate parent by default and render into its parents 'outlet' by default. You could think of the Router looking something like this.
For Illustrative purposes only:
Notes.Router.map(function() {
//think of this as your application level stuff that Ember just does!!
//this is not written like this but to illustrate what is going on
//you would get application template, ApplicationRoute, ApplicationController
this.resource('application', function() {
//this is an index that you get for free cause its nested
//its that index template, IndexController, and IndexRoute you were using
this.route('index', { path: '/' });
this.resource('foo', {path: 'somePathYouPutHere' }, function() {
//since you started another nested level surprise you get another `index`
//but this one is `foo/index` template.
this.route('index', {path: '/'});
this.route('zoo');
});
});
});
The first part of the above exaggerated router example, Ember does automatically behind the scenes, its part of the 'magic' you hear about. It does two things it sets up an Application environment for its self and you get ApplicationRoute, ApplicationController, and a application template which are always there behind the scene. Second it makes that index and you get IndexController, IndexRoute, and a index template that you can use or ignore. So if you do nothing else, no other code that declaring and Ember App in a file like var App = Ember.Application.create(); and open the Ember Inspector and look into routes you will see the above mentioned assets.
Now, the resource foo in the above router is an example of a resource you would make and as you see you get an index in there because you started to nest. As mentioned above you do not have to define the index at each nest level, this.route('index', {path: '/'}); from inside foo could be totally omitted and Ember will still do the same thing. You will end up with foo/index template, FooIndexRoute, FooIndexController along with the expected foo template, FooRoute, and FooController. You can think of thefooindex as a place that says 'hey' before anything else gets rolled into my parentfoo` and gets rendered I can show something if you want, use me.
This is also a good time to highlight what happens with namespace when you nest route in a resource like this.route('zoo') in the above example. The namespace of the route zoo is now going to be appended to resource foo and you end up with foo/zoo template, FooZooRoute and a FooZooController.
If you were to change zoo to a resource nested in the foo resource this.resource('zoo'); the namespace will be keep for zoo. You will end up with 'zoo' template, ZooRoute and a ZooController. The namespace is kept. Ok, enough side tracking what about your App.
You said that you wanted / url of your app to render the list template. In order to accomplish that you have to override the default behavior that happens when Ember boots up. You override the top level / by adding the {path: '/'} to the first resource or route in the Router. From the fake router code above the first index route you get is associate with the application. By default if you do nothing Ember will push that index template into the application template. However that is not what you want you want your list template to be pushed into the application template when you hit the base url of /' for your App.
Notes.Router.map(function() {
this.resource('list', {path: '/'});
this.resource('new');
this.resource('note', { path: ':note_id' });
});
By adding the code {path: '/'} to the first resource like I did above, you are now telling Ember 'hey' when my app url reaches the base url of / or when you boot up use my list template not your default index template and render that into the application template. In addition since the other resources are not nested when your App transitions to those routes via the url they will blow out whats in the application template {{outlet}} and replace themselves in there.
You mentioned about defining a "path" in a route what that does is tell Ember how you want to represent that route in the url. In the above example if you leave the new resource as is, Ember by default will use the routes name as the path, the url would be /new. You can put any name in path for the new resource, this.resource(new, {path :'emberMakesMeKingOfWorld'}); and that name will be represented in the url as /emberMakesMeKingOfWorld and that long thing will still be associated with you new route. Your user might be confused what this url means but behind the scence you would know its tied to your new route. Its just an example but probably good practice to use descriptive names so your user knows what hitting a url in your App is meant to do.
After overriding the default index template that is associated with the application. I moved your code into the application template. The reason for that it seemed as though you wanted that bar with the 'newNote' action to be present all the time. If you want something present all the time in your App, like a navigation bar, footer, im sure you can think of better stuff, place it in the application template.
Here is a JSBIN and I adjusted you code a little
