Rails - May 2006 - Stupid newbie question

Here''s a request string which has a value I want to pull out from the 
category array - parent_id.

Parameters:
{"category"=>{"name"=>"Condiments",
"parent_id"=>"1"},
"commit"=>"Create"}

How do I reference that subelement in the receiving script?  I''ve tried

params[:parent_id]
params[:category[:parent_id]]

both unsuccessfully.  I told you this was a stupid question.  So how do I 
get at those values?

Mike

I''d try:

params[:category][:parent_id]

Hi Mike,

You were close ;-)  It''s params[:category][:parent_id]

It''s a hash of hashes.

Best regards,
Bill

Long version

category_hash = params[:category]
category_hash_parent_id = category_hash[:parent_id]

As bill said it''s a hash [:category, :commit] that contains another
hash[:name, :parent_id]
