Access current_user variable from .js application in Rails 3

I want to access my current_user variable from my .js application (I renamed the application application.js to application.js.erb so the server can understand my ruby ​​code), so I got something like:

function hello(){ alert("<%= current_user.name %>"); }

But he fails:

enter image description here

How can I get session variables, such as current_user, from a devem gem running from a script located in / assets / my _script.js.erb, I think it cannot be bypassed because these variables may not be available to public sites, or what to do with it?

Thank!
