Just hide or remove the DOM element. It’s quite a simple task.
- Match User Agent string with Ruby and set a boolean on a match**.
- Javascript to hide the DOM element if the boolean is true.
This is basically the “standard” way to do this and similar tasks where a developer does not want to show (or wants to remove) any DOM element.
**Note:
Using the ‘gon’ Ruby gem makes passing any Ruby variable to Javascript very simple, but I have only used it on a Rails app, not with EmberJS in the stack (anyway, there are many ways to pass a Ruby variable to JS)..
