Filter child-records (hasMany association) with Ember.js

Question

Is there any possibility to filter the hasMany records from a model record? I want to get the active projects, grouped by the customer.

Customer

Answer 1

I think the following could work:

controller

Docket.OrganizationProjectsIndexRoute = Docket.AuthenticatedRoute.extend({
  setupController: function () {

    var projectsController = this.controllerFor('organization.projects');

    this.store.find('customer').then(function(customers) {
      var promises =  customers.map(function(customer) {

        return Ember.RSVP.hash({
          customer: customer,
          projects: customer.get('projects').then(function(projects) {
            return projects.filter(function(project) {
              return !project.get('archived');
            });
          });
        });             

      });

      Ember.RSVP.all(promises).then(function(filteredProjects) {
        projectsController.set('filteredProjects', filteredProjects);
      });

    });            

  }
});

template

{{#each filtered in filteredProjects}}
  Customer {{filtered.customer}}

  {{#each project in filtered.projects}}
    Project {{project.name}}

  {{/each}}
{{/each}}

The trick is use Ember.RSVP.hash to group each customer by active projects.
