How to select all check boxes in ember 2.3.1

I have a data grid made of table. I need to select all rows in that table.

I am using mirage for fetching data.

Can you be more specific?

Do you want a checkbox that when checked selects all rows in a table?

My router:

export default Ember.Route.extend(AuthenticatedRouteMixin, {

model: function() {

return  $.getJSON(ENV.apiHost + "/api/forum/user/all");


afterModel: function(model) {

model['entities'].setEach('isDrop', false);

}, …

And my controler:

export default Ember.ObjectController.extend({ selected: false,

isDrop: false,

allChecked: null, allCheckedWatcher: function(){ var model = this.get(‘model’); if(this.get(‘allChecked’) === true){

    model['entities'].setEach('isDrop', true);
} else {

    model['entities'].setEach('isDrop', false);
