</div>

is there a way to pass the data returned by the to\_parm function in a  
helper?

i followed the info provided at  
[Best Online Casino in Australia | Top Licensed Casinos for Gamblers](http://www.jroller.com/obie/entry/seo_optimization_of_urls_in) and am  
able to successfully get the correct urls, now i want to be able to get  
the same (id-whatever) text and pass it to a helper function for further  
processing.

Any ideas as to how this can be achieved?

It can be accomplished by calling the to\_param (not to\_parm) method on  
the object in question. For instance, @city.to\_param, where @city is a  
City object.

Thanks for the information. That solved one of my problems. 🙂
