Rails - Jul 2006 - ActiveRecord/ActionController in javascript code

Hi,

I have a javascript file for generating a menu when the user hovers over 
a link. These links are basically a list of logged in users. Now, in the 
menu I would like to have a link to "Display Profile" so that a user
can
view the profiles of other users. Also nice would be a picture in the 
menu.

The problem is obviously that the javascript expects static links. But I 
want to have things like @user.name (ActiveRecord) or even a call to an 
ActionController action which could display the profile.

If these are impossible then hopefully there must be some other way to 
achieve this. Any help would be greatly appreciated.

Thanks!

How about, as a suggestion use a partial that generates the javascript
array (im guessing the "static links" are in an array) then that
partial
could use a helper to do the lookup to activerecord and display the text
you want. 

Does that help?

Having direct access to ActiveRecord in JS seems like a big violation of 
MVC.. you need to chk out RJS - it''s not going to give you this 
functionality out of the box but should prove insightful enough to get 
you a pretty clean solution.

Thanks for the reply, Jonathan. Well, the problem with that is still the 
same: how do I place the generated array within the javascript code 
itself? Or how to have the javascript code access the array generated by 
the partial?
