Showing a main template within a secondary template

Question

Showing a main template within a secondary template

Currently, I am in the process of developing a robust master view application using cordova and JavaScript. The goal is to present users with a list of products, allowing them to select one and navigate to a tabbed detail page specific to that product. Each tab within the detail page will dynamically generate based on the selected product. Despite loading product-specific information, I also want to maintain a complete list of all products for users to switch between at any time. To provide a clearer visualization of this concept, refer to the accompanying image.

While attempting to implement this functionality with ember.js, I encountered several challenges. Although I succeeded in generating an initial list of products and transitioning to product details, I faced complications when trying to load the master product list within my secondary template, resulting in technical issues. I understand the concept of including two templates with an {{outlet}} directive in the parent template, but I struggled to make the child inherit from the parent. Is it feasible to achieve this in ember, or should I explore alternative frameworks such as Angular? Any insights or guidance would be greatly appreciated.

Ember stands out when it comes to displaying nested templates, offering advantages not found in other frameworks.

Utilizing nested resources in the router is a simple way to achieve this functionality. Here's an example:

App.Router.map(function() {
  this.resource('products', function() {
    this.route('product', { path: '/product_id' });
  });
});

Remember to fetch data for each route accordingly. For instance:

App.ProductsRoute = Ember.Route.extend({
  model: function() {
    this.store.find('product');
  }
});

App.ProductsProductRoute = Ember.Route.extend({
  model: function(params) {
    this.store.find('product', params.product_id);
  }
});

In your product template, make sure to include an {{outlet}} for child routes to render into (e.g., products.product).

Here's an illustrative example:

product.handlebars

{{#each}}
  {{name}}
{{/each}}

{{outlet}}

products/product.handlebars

Product: {{id}}

For more details on routing, refer to the resources section in the guides.

EDIT

If you need different displays for the master list in the products template and the products.product template, move the master list to both the products.index and products.product templates.

Also, ensure that both ProductsIndexController and ProductsProductController reference their parent models using needs. This setup grants access to products via controllers.products in both templates.

App.ProductsIndexController = Ember.ObjectController.extend({
  needs: 'products',
  products: Ember.computed.alias('controllers.products')
});

App.ProductsProductController = Ember.ObjectController.extend({
  needs: 'products',
  products: Ember.computed.alias('controllers.products')
});
