I start to study Ember.js
and I know some of conventions like 'application.hbs', 'index.hbs' but I don't know what kinds, how many conventions exist..
And, As I searched google, I got name of conventions. I think there are too many conventions in Ember. where do I search in google?? I already read https://guides.emberjs.com/v2.8.0/getting-started/quick-start/ from tutorial to glossary. but... still don't know what it is..
If someone know any summary or any sites about the convention, please help me. Thanks.
Routes and Pages
Ember applications are organized by pages (called routes). Each page in your application will have it's own route, and a route.js as well as page_name.hbs template assosciated with it. Any HTML written in the template will be rendered only on that page.
Your application will also have an individual application.hbs. Anything placed in here will be rendered on every single page, so you don't have to copy code for something like a navigation bar.
All of the various pages are mapped to URLs in your application router (router.js). Below is an example of a route map:
Router.map(function() {
this.route('home', { path: '/' });
this.route('page1', { path: '/pathToPage1' });
this.route('page2', { path: '/pathToPage2' });
});
Optional Pod Styles
Not entirely sure what you mean by convention, but at the highest possible level there are 2 widely used ways to organize an ember app.
By default, ember groups your application files based on type, with
all of the styles in a styles/ folder, templates in a templates/
folder, component templates in components/templates/ etc.
The alternative method is to use pod-styles, where your
application is organized by component (grouping templates (.hbs),
styles (.css), and routes (.js) ). Refer to this awesome tutorial
for help with that: http://www.programwitherik.com/ember-pods/
Handlebars Templating
Ember uses the Handlebars templating library to power the UI, and is used to declare components, helpers, etc. Handlebars works perfectly with HTML, however, and the 2 languages can be used in the same file without conflict.

I am really new to Ember, which I am asked to do and well, love to learn. Basically, the current project uses Gentelella Admin Dashboard. I being trying to get the dashboard to load properly but failed.
After I login, I get redirected to /dashboard/ route, which basically loads the main dashboard interface. Now the problem is I can't click-expand the menus on the sidebar nor toggle the sidebar menu. And the main page is not extended to fill the space, as in our current application.
I know the function init_start() takes care of the resize and the click, which is already added to vendor.js from custom.js but I can't seem to call the function from ember at all.
My latest attempt was using mixins but it failed too:
import Ember from 'ember';
export default Ember.Mixin.create({
activate: function() {
this._super();
init_sidebar();
}
});
then from dashboard.js route:
import HandleTempLoadMixin from '../mixins/handle-temp-load';
export default Route.extend(AuthenticatedRouteMixin,HandleTempLoadMixin, {
});
but still the function is not executed.
I have read that it is best to avoid working with jquery inside ember in SO but I have pretty much many JQuery functions that I cant transfer right now (nor sure why exactly since it says somewhere in the documentation jquery is built into ember itself).
Anyway, what is the best way to initailize the dashboard interface?
From my understanding you have some jQuery stuff that you would like to utilise. I suggest looking into Component's didInsertElement hook and triggering your custom code from there.
You can find more details in here https://guides.emberjs.com/v2.17.0/components/the-component-lifecycle/#toc_integrating-with-third-party-libraries-with-code-didinsertelement-code
In general, try avoid working with view related stuff in Routes. Ember's power comes from strong conventions. Learning where to place your code is crucial.
I am brand new to ember... working through the ember guides AND trying to apply that same knowledge through the ember-cli guides simultaneously.
I am noticing there there are a few big gaps in logic between the two when it comes to the ES6 Resolver and it is causing problems for me, particularly when i want to reference things like ApplicationRoute, ApplicationController, and the like.
I have to ask, for my own sanity, how to I define an ApplicationRoute or an ApplicationController? Are they saved as application.js or index.js?
ApplicationRoute would be saved under app/routes/application.js, ApplicationController would be saved as app/controllers/application.js.
as long as those files export default the proper subclassed Route or Controller, respectively, everything should be fine.
I have multiple Ember apps that live in a Middleman app. The current directory structure is
[app-name]
components
helpers
source
assets
img
css
js
// jQuery for other pages
app.js
// An ember app
fullscreen
components
controllers
models
routes
views
app.js
// Another ember app
sandbox
components
controllers
models
routes
views
app.js
demos
// These currently contain the templates, in script tags
fullscreen.erb
sandbox.erb
I'm trying to figure out how I can move the templates out of the script tags. At this point, I've spent quite a bit of time trying to get various solutions to work:
https://github.com/mrship/middleman-ember
https://gist.github.com/GutenYe/4364010
http://nerdyworm.com/blog/2013/05/06/ember-dot-js-and-middleman/
This last one I had working at some point, but can't get it working again now.
What's the simplest way to accomplish this? I am new to Sprockets and Rack, which is making this harder for me to sort through.
Generelly its not hard to build this by yourself. U just need a JS runtime, compile the templates, and put them into Ember.TEMPLATES.
Have a look on precompilation: and the TEMPLATES Hash
I'm writing a feed reader plugin for wordpress.
Feeds have entries. Click on a feed, show the entries from that feed.
I have that working in older versions of ember, but when I try to upgrade to the release candidates it seems like we have to have a router. Defining routes etc is turning into a major headache and I'm wondering if I can just use the databinding that I came to ember for.
Is there a way to just use the databinding to controllers and models without having to go through the whole router business?
Is there a way to just use the databinding to controllers and models without having to go through the whole router business?
Yes it's possible to use ember without the router. It will still be there in background but won't cause any trouble. Just set location: 'none' and then customize App.ApplicationController, App.ApplicationView and application.hbs as necessary. You may find it is still useful to customize the App.ApplicationRoute as well.
App.Router.reopen({
location: 'none'
});
FWIW #commadelimited is right, checkout the Peepcode video and consider taking advantage of the router.
Ember's routes have smart defaults so if you're app is pretty basic, you may not need to touch the routes.
location:none simply makes it so you're url doesn't show state changes, which can be useful
If you're app doesnt have any use for routes(maybe it's super small) you can simply put everything into a controller on your initial state/route and not worry about it.
But even if you have a simple setup of a few states:
App.Router.map(function() {
this.resource("index", { path: "/" }, function(){
this.route("stuff", { path: "/stuff" });
this.route("otherstuff", { path: "/otherstuff" });
});
});
the routes default action is take care of the magic behind that, so you shouldnt need to do anything :)
From Trek's tutorial:
Your application must have an ApplicationView property. An instance of
this class will be created for you and inserted into the application's
view hierarchy as the root view.
And the tutorial gives this example code:
App.ApplicationView = Ember.View.extend({
templateName: 'application'
});
App.ApplicationController = Ember.Controller.extend();
What is special about ApplicationView and ApplicationController? Is their particular name reserved and must be used by conversion or is there something special about the way the router refers to them?
As I understand it, one of Ember's principals is to eliminate boilerplate code. So I am guessing there is something more to explicitly creating these two views for every app as starting point -- otherwise Ember would just make them for me behind the scene.
To rephrase my question, what makes ApplicationView and ApplicationController special in an Ember application. Do I need to create them explicitly for every app and if so, do I need to name them following a convention?
Note: I am using ember-latest
Ember.js tries to adhere to the programming philosophy of convention over configuration. Because of this some things need to be specifically named and follow correct casing rules. Upon calling App.initialize() your application looks for the property on itself App.ApplicationView. Your app then renders this view, inserts it into the dom and auto-creates an instance of App.ApplicationController, setting it as the render context for your ApplicationView. This means that any properties in your ApplictationController can be bound in your ApplicationView simply by referencing them in the view.
If you call App.initialize() with out an App.ApplicationView or App.ApplicationController ember will throw an error letting you know you must create them.
ApplicationView and ApplicationController are integral parts of your ember application and must exist. Ember is an MVC framework, ApplicationView is your root V, ApplicationController is your root C. It can be tempting to try to use frameworks like ember for just the pieces that you want, but with just a little more work you'll have a much more robust, and easy to use application that trying to cherry pick functionality.
