I am not getting complete example of EMBER.SORTABLEMIXIN.I don't have any idea about sorting in ember.

Can anyone explain me how to do sorting in ember using my this example(Not working)?

Answer 1

The sortable feature is provided by Ember.SortableMixin. This mixin expose two properties: sortAscending and sortProperties.

• The sortAscending accepts a boolean value determining if the sort is ascendant or not.

• And the sortProperties expect an array with the properties to sort.

For instance:

Controller

App.IndexController = Ember.Controller.extend(Ember.SortableMixin, {
    sortAscending: false,
    sortProperties: ['id'],
});

These properties can be changed and the order will be updated, here is a sample with dynamic sort:

Controller

App.IndexController = Ember.Controller.extend(Ember.SortableMixin, {
    sortProperties: ['firstName'], // or whatever property you want to initially sort the data by
    sortAscending: false, // defaults to "true"
    actions: {
        sortBy: function(property) {            
            this.set('sortProperties', [property]);
        }
    }
});

To access the arranged content, you should refer to arrangedContent in your template instead of the regular model property. Like this:

Template

<script type="text/x-handlebars" data-template-name="index">
    <h2>Index Content:</h2>
    <table>
      <thead>
        <th {{action "sortBy" "id"}}>ID</th>
        <th {{action "sortBy" "firstName"}}>First Name</th>
        <th {{action "sortBy" "lastName"}}>Last Name</th>
      </thead>
      <tbody>
        {{#each arrangedContent as |prop|}}
        <tr>
          <td>{{prop.id}}</td>
          <td>{{prop.firstName}}</td>
          <td>{{prop.lastName}}</td>
         </tr>
        {{/each}}
      </tbody>
    </table>
  </script>

I hope it helps

Since Ember.SortableMixin is going to be deprecated in Ember 2.0 (as well as the ArrayController), the recommended way to sort will be using Ember.computed.sort(), as illustrated here: https://stackoverflow.com/a/31614050/525338
