EmberJS Challenge: Application Template

Link to challeneg: http://teamtreehouse.com/library/emberjs/routes-and-templates/challenge-application-template

Challenge Task 1 of 1

In index.html, there are two templates, "kittens" and "puppies". They have a lot of duplicate code, though. Move the duplicated code into the application template, but be sure to leave the <h1> and <p> tags in the "puppies" and "kittens" templates. Ensure that the application template renders the nested resources.

I honestly have no idea what we're supposed to be doing in this challenge?!

I watched the video several times: http://teamtreehouse.com/library/emberjs/routes-and-templates/the-application-template-summary

In the video they're making a separate file, but this challeneg says not to make a separate file but to do the pasting into an already existing file?

Huh? What? :grimacing: :confused:

Anyway, I spent all day randomly pasting things and switching things around until I arrived at:

<!DOCTYPE html>
  <title>Animal Shelter</title>
  <script src="js/libs/jquery-1.10.2.js"></script>
  <script src="js/libs/handlebars-v1.3.0.js"></script>
  <script src="js/libs/ember-1.8.1.js"></script>
  <script src="js/app.js"></script>

  <script type="text/x-handlebars">

    <div class='container'>
      <nav class='navbar navbar-default' role='navigation'>
        <ul class='nav navbar-nav'>
          <li>{{#link-to 'kittens'}}Kittens{{/link-to}}</li>
          <li>{{#link-to 'puppies'}}Puppies{{/link-to}}</li>



  <script type="text/x-handlebars" id="kittens">
       <p>Look at these kittens! They are so cute.</p>
       <p>These puppies will love you and snuggle you until your heart melts.</p>

  <script type="text/x-handlebars" id="puppies">
      <p>These puppies will love you and snuggle you until your heart melts.</p>


Yes, it finally passed, but don't ask me what I did or why?

It's all just "magic code" stuff. alt text

I'm just a beginner in Ember, but here's what I think is happening:

You can think of the different <script type="text/x-handlebars"> sections as different template files.

The challenge is about combining two separate and somewhat redundant template files into a common template file which includes an {{outlet}} which will pull in two other nested templates, in this case kittens and puppies.

The top-level template also contains links such as {{#link-to 'kittens'}} which reference the routes for those two nested template files. The routes are defined as resources in the js/app.js file.

And indeed, because these pieces are all named carefully, Ember "magically" knows how to associate the routes and templates.

Does that help at all?

Thanks Ian, that was a better way of thinking about the EmberJS "techno-magic"..
