I am more specific now.

There is one swf file. When I click on that swf file it will return 
user_id.
And below that swf file I have to show detail of the specific users. The 
detail will come from database. Now the problem is that there is small 
javascript function which will give me the user id. So from that 
javascript function I wanna call rails method which will fetch data from 
database and show it where I want.

call the action like "/controller_name/action_name.js" this from the
javascript file, if the call is ajax make your controller respond to js
then the file action_name.js is really named action_name.js.rb file there do
<%=render :text => user.id%>


this is what should happen, you call from the javascript
"/controller_name/action_name.js", this goes to the route and matches

map.connect /:controller/:action.:format

you see the format at the end ? rails will return the action_name.js.rb
ignoring the rb part as it does with index.html.rb that file will render the
text with the user id, another option is returning a json object, read a bit
about it because i think json is the way to go.
