Accessing meta information passed in a json server response

Question

I am using the Ember-Data Rest-Adapter and the JSON returned from my server looks basically like the one in the Active Model Serializers Documentation

{
  \"         


        

Answer 1

I figured out a way to access the meta information passed in a response. But unfortunately it really does not seem to be supported by ember-data out of the box and I am writing the meta information to a global variable that I am then accessing via bindings in the requesting controller.

I ended up customizing the serializer the RESTAdapter is using:

App.CustomRESTSerializer = DS.RESTSerializer.extend({
  extractMeta: function(loader, type, json) {
    var meta;
    meta = json[this.configOption(type, 'meta')];
    if (!meta) { return; }
    Ember.set('App.metaDataForLastRequest', meta);
    this._super(loader, type, json);
  }
});

App.Store = DS.Store.extend({
  revision: 11,
  adapter: DS.RESTAdapter.create({
    bulkCommit: false,
    serializer: App.CustomRESTSerializer
  })
});

I am aware that this is not particularly pretty and actually think that this is against what ember-data expects us to do but fot the time being it's working correctly.

I will try to get this working with ember-data in a better way and submit a pull request when it is working or open an issue on github when anybody else is interested in getting this to work.

If anybody finds a more clean solution to this please let me know.
