How to insert multi line string into coffeescript/jquery value with Rails

I have some CoffeeScript in my Rails project, with which I'm trying to update a textarea. My CoffeeScript is:



$('#video_description').val(<%= @description %>")


The returned text is a string from the YT gem (a description from one of my YouTube videos). An example can be:



Testing that this works

Does this work?


When I load the page and inspect it with the Developer Tools in Chrome, the CoffeeScript looks like:



$('#video_description').val("Testing that this works

Does this work?")


The new line avoids the CoffeeScript from making sense to the interpreter, and it raises the following message:



Uncaught SyntaxError: Invalid or unexpected token


I've tried replacing the CoffeeScript with:



$('#video_description').val(<%= h @description %>")


This has no effect (other than to escape all the single quotes in the actual string). It has something to do with the fact the string is dropped into the quotes as is.



I need to have the text string to have n instead of the carriage return.



Any help to solve this would be great.

          Use the escape_javascript() method (shortcut: j()) 



          $('#video_description').val("<%= j(@description) %>");

          • Thank you so much. Greatly appreciated. I had no idea that's what the j() meant.

          Run scheduled task as local user group (not BUILTIN)

This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem?
