ember-reload-record is a mixin for routes, to support reloading of records.

In a complex system the server mutates objects and processes them in manifold ways. For instance, a change to one object may change the state of another object. An object may be deleted by another user without notice, and there is no obvious way to propagate such events to other users and do the right thing.

Even duplicating server logic precisely on the client doesn't solve the problem, since a model might be deleted by another user while still cached on the client. The solution is to aggressively reload models.

The basic notion would be to reload the course in the afterModel hook. However, simply doing that would cause double loading, in the case that the record did not already exist in the store and had been loaded via the model hook.

Installation

npm install ember-reload-record

In Brocfile.js:

app.import('node_modules/ember-reload-record/reload-record.js');

Usage

In your routes, make sure to call _super from the beforeModel and afterModel hooks if implemented, and return its value, or else this won't work.

Example:

App.MyRouteNeedingReloading = Ember.Route.extend(
  ReloadRecord
).reopen({
  beforeModel: function() {
    blahblah;
    return this._super.apply(this, arguments);
  },

   model: function(params0 {
     return this.find('model', params.model_id);
   },

   afterModel: function() {
     blahblah;
     return this._super.apply(this, arguments);
   }
});
