How to fetch all data in one request in Ember Data?

I am using the ember 1.8.1, ember data 1.0.0-beta 11. I have two types name A and B the relationship is like

A = DS.Model.extend({
   bs: DS.hasMany('B', {async: true})
});
B = DS.Model.extend({
   a: DS.belongsTo('A')
});

According this post: http://thau.me/2014/09/ember-data-mastering-async-relationships/

When I try to fetch the bs in a.model in template like this: {{#each b in model.bs}}

The ember's RESTAdapter will send a http request like this: URL/bs?ids[]=1&ids[]=2

But it will send several request like this: URL/b/1 URL/b/2

Is the behavior of ember data changed in new version? How can I combine the requests to 1 request?

This behaviour changed in Ember Data beta-9 to be opt-in. You can activate it by setting the coalesceFindRequests property of your adapter.

   DS.RESTAdapter.reopen({
     coalesceFindRequests: true
   });

A more detailed description can be found in the offical blog entry for beta-9: http://emberjs.com/blog/2014/08/18/ember-data-1-0-beta-9-released.html#toc_coalescing-find-requests
