Hello,

thanks for reading this. 🙂 I’ve got some problems with RJS in  
separate files. What’s the correct extension? When I name it \*.rjs /  
\*.js.rjs, Ruby on Rails complains that it in not able to find a  
\*.js.erb template. But when I name it \*.js.erb, nothing is translated  
to javascript, only the raw text is given back to the client. When I  
try inline RJS directly in my controllers with “render :update …”,  
it runs perfectly. What am I doing wrong?

Really thank you for any answers.

The right naming is \*.js.rjs

At the end of the controller you need:

respond\_to do |format|  
format.js  
end

to make that work

Keep this bug report in mind if you’re calling #render\_to\_string  
before the default view is rendered:  
[http://rails.lighthouseapp.com/projects/8994/tickets/870-js-rjs-views-no-longer-found-after-render\_to\_string-call](http://rails.lighthouseapp.com/projects/8994/tickets/870-js-rjs-views-no-longer-found-after-render_to_string-call)

The solution is to rename the default view to filename.rjs (as opposed  
to filename.js.rjs).

Cheers,  
Nick
