Hi
I'm working with rails 2.1.0 and with nested resources.
My links i generate with the following helper:
link_to @state.name , [@country , @state ]
Everything works fine and the urls are correctly generated.
But now I'd like to add an additional parameter to the url like:
/country/1/state/2?category=2
The additional parameter will only be used for filtering in the show
action, so I don't want to add a new nested route.
How can I generate an URL with such a parameter? I did not find any
solution to this problem...
Thanks very much for your help!

url_for @state.name , [@country , @state ], :category => 2
will do the trick

But url_for expects only one parameter ... Do I have the wrong rails
version??
Julian
Yes, It take only 1 argument, but, if you use
link_to @state.name , country_state_path(@country , @state , :catergory => 2)
thats seems to work (a bit tested this time
hope it will work

That really works, thanks! Unfortunately I'd like to use the link_to
helper with the array notation [@country , @state ], because the
resource is polymorphic.
With link_to(@state.name , [@country , @state ], :catergory => 2),
catgory is added as an attribute to the HTML link-tag.
Do you have an other idea? A workaround would be to write a new
link_to helper...
Julian
last idea... take a look at polymprphic_url, and polymorphic_path
) but it is a bit longer.
