How to specify "element(by.id" or "element(by.css" in Ember.js using Protractor

New to ember.js -- used http://yoember.com/ to create a Demo ember.js site. I'm trying to figure out how to use Protractor to test certain elements, but I'm encountering issues specifying them.

Most, but not all, elements (buttons, text areas, etc) have a serialized id value: id='ember###' that changes every time the page is reloaded, which makes it impossible to indicate some elements in Protractor (like, element(by.id('ember557')).sendKeys('foo');).

Running a command like the one above will return the error: Failed: No element found using locator: By(css selector, *[id="ember557"]), which is due to the 3-digit id value changing.

In my demo app, I was able to go into the /app/templates/components/ file for that page and manually add something like id='name' into the handlebars input and was able to successfully find and test that element in Protractor.

This isn't ideal though, and I'd like to find a way to test sites that I don't have the ability to modify the html of.

Can anyone help me wrap my head around this? Thanks.
