Hello folks,

I’d like to include the javascript generated by an RJS file in an  
RHTML file using the tags. I was going to use  
javascript\_include\_tag to do this, mostly in order to ensure that the  
contents are not cached by the browser.

Unfortunately, javascript\_include\_tag appends a “.js” to the file name  
if there is not a period in the file name. This means that I cannot  
do

\<%= javascript\_include\_tag ‘/browse/read\_variables’ %\>

when read\_variables is an action in the browse controller with an RJS  
template.

There are various ways to work around this behaviour, but it seems  
like a reasonable approach that should work. Is there a way to use  
javascript\_include\_tag with an action? If not, is it something that  
should be corrected in Rails, or is my usage too obscure/wrong/  
whatever?

Thanks,  
Mike.
