Ember. How to filter data?

Question

Ember.js

I am using CouchDB as a database.

//route
import Ember from 'ember';

export default Ember.Route.extend({
  model: function () {
    return this.store.findAll('task');
  }
});

//model
import DS from "ember-data";

export default DS.Model.extend({
  assigned: DS.attr('string'),
  client: DS.attr('string'),
  contact: DS.attr('string'),
  date_finish: DS.attr('string'),
  date_start: DS.attr('string'),
  priority: DS.attr('string'),
  state: DS.attr('string'),
  text: DS.attr('string'),
  title: DS.attr('string'),
});

I get the necessary data from the database. How to filter the data, for example by the "state" field?

Answer 1

Depends on how you use the data.

export default Ember.Route.extend({
  model: function () {
    return this.store.findAll('task').then(function(tasks){
        return tasks.filterBy('state', 'done');
    });
  }
});

or

export default Ember.Component.extend({
  filtredData: function() {
    return this.get('data').filterBy(this.get('filterKey'), this.get('filterValue'));
  }.property('data', 'filterKey', 'filterValue')
});
