# Instead do this and use the patch below to get a live array:
hasManyHack foo, 'bars'

If you have worked much with Ember-Data, then you know the buffered object proxy pattern:

http://coryforsyth.com/2013/06/27/ember-buffered-proxy-and-method-missing/

This pattern allows us to put changes to a model into a buffer instead of on the model itself. There are several benefits of this:

• If the model has changes come from a push source (an attribute is updated), the changes will not destroy what the user is currently entering.
• Saves can be de-coupled from dirty tracking. If you are saving a model as a user types, the model in flight will not accept changes from the user. You will get the dreaded cannot change an object inFlight error. With a buffer, you can commit the buffer to the model and save the model, then allow the user to keep making edits against a new buffer. No conflict.
• In general, a buffer allows you to treat Ember-Data records more like database rows. You lock them for modification (while persisting them) but only for the shortest time possible. An object is made dirty then sav

urlTemplate Proposal

Summary

urlTemplate improves the extesibility of API endpoint urls in RESTAdapter.

Motivation

I think that Ember Data has a reputation for being hard to configure. I've often heard it recommended to design the server API around what Ember Data expects.

If behind a VPN (AnyConnect) do the following:

boot2docker down
vboxmanage modifyvm "boot2docker-vm" --natpf1 "docker,tcp,127.0.0.1,2376,,2376"
boot2docker up
export DOCKER_HOST=tcp://127.0.0.1:2376

To expose a port from boot2docker to host (osx):
