I have the following function for using ZenDesk. I'd like to inject my current_user details into the form as follows. (this is my from html.haml template). However I cannot figure out how to make this work.

:javascript
    if (typeof(Zenbox) !== "undefined") {
      Zenbox.init({
        dropboxID:   "xxxxx",
        url:         "xxxxx.zendesk.com",
        tabID:       "support",
        tabColor:    "black",
        tabPosition: "Left",
        requester_name:  =current_user ? "#{current_user.first_name} #{current_user.last_name}" : "" ,
        requester_email: =current_user ? "#{current_user.email}" : "" ,
        hide_tab: true
        });
    }

In short, how does one inject rails variables into a :javascript element in haml.

This should work ie. put all inline ruby inside of #{}:

requester_name:  "#{current_user.first_name + ' ' + current_user.last_name if current_user}",
requester_email: "#{current_user.email if current_user}",
