Ember model reloading in interval

Question

I have a User model, which has latitude and longitude properties, which are used to show current user location on map.

App.User = DS.Model.extend({
    firstName         


        

Answer 1

EDIT: Please see Dmitri Zagidulin's answer.

So I figured it out. For now all I need was to override didLoad method on model, in future I will probably need more complex solution, but this is adequate for now.

didLoad: function(){
  var self = this;
  setInterval(function() {self.reload()}, 5*60*1000); //every 5 minutes
}

In case someone needs to reload more models, good solution would be to implement this as Mixin.

Answer 2

For those who are coming across this question now -- don't use setInterval, it's been shown to cause serious memory leaks.

Use Ember's own Ember.run.later instead.

Answer 3

The model has a .reload() method now, which you could use in a setInterval callback. See https://stackoverflow.com/a/14183507/363073

P.S. Watch #545.
