how to update ember-cli app to ember-data 1.0.0-beta9?

Question

I have an ember-cli application. It seems like ember-cli uses ember-data 1.0.0-beta.8.2a68c63a at the moment by default. (at least thats loaded into the browser with ember serve)

But i wanna use the current beta.9, because the recent changes on DS.DateTransform.

How can I update my ember-data version?

Its confusing because ember-data seems to be installed twice! Once with bower (but I have no dependency in my bower.json), and once with npm (but here the ember-cli-ember-data).

The installed version with bower seems to be 1.0.0-beta.10 (why 10? On emberjs.com only 9 is listed!), but the ember-cli-ember-data npm modules has a ember-data 1.0.0-beta.8.2a68c63a loaded. A recent change on the github repo is telling me that is now deprecated, and I should update my package.json, but how, and why is ember-cli not doing that for me?

Thanks for help to install ember-data 1.0.0-beta.10!

To update to the latest version of ember-data you should run

npm uninstall ember-cli-ember-data --save-dev
npm install ember-data --save-dev

The reason for the change is that ember-cli-ember-data was just a wrapper package which was being used to include ember-data into an ember-cli project. ember-data was recently updated to be able to be able to be used an ember-cli addon without needing a wrapper package (which is why ember-cli-ember-data is being deprecated).

The issue you are seeing with ember-cli-ember-data is because ember-cli changed the way that it loaded bower dependencies. It used to merge files from both the vendor and bower_components directories.

The way ember-cli-ember-data worked was...

• ember-cli-ember-data placed a default version of ember-data (which was beta.8) in the the vendor directory
• you were able to update the files in the bower_components directory by specifying a newer version in your package.json
• the bower_components directory would get merged into the vendor directory (with your updated version replacing the version from ember-cli-ember-data)
• ember-cli-ember-data then imported the ember-data files from the vendor directory

Now that the bower_components directory is not being merged into the vendor directory what is happening is that ember-cli-ember-data always loaded its version from the vendor directory (which is why you are getting beta.8)
