How to add a filtered array to a model in ember.js?

To add a filtered array to a model in Ember.js, you can use a computed property in your model definition. Here's an example of how you can do this:

import Model from '@ember-data/model';
import { computed } from '@ember/object';

export default Model.extend({
  allItems: [], // This is your original array of items

  filteredItems: computed('allItems', function() {
    // Filter the allItems array based on some condition
    return this.allItems.filter(item => item.someProperty === 'someValue');
  })
});

In this code snippet, we define two properties in our model: allItems and filteredItems. The filteredItems property is a computed property that depends on the allItems property. It uses the filter function to create a new array containing only the items that meet a specific condition (in this case, item.someProperty === 'someValue').

You can then use the filteredItems property in your templates or controllers just like any other property in your model. Whenever the allItems array changes, the filteredItems property will automatically be updated to reflect the filtered array.

Remember to replace 'someProperty' and 'someValue' with actual property names and values that you want to use for filtering.
