POST parameters

Hello...

Stupid question I'm sure...but I have tried:

params[:permission[:user_id] etc., etc...

And I can get to the user_id variable.

Parameters: {"commit"=>"Add", "permission"=>{"document_id"=>"1",
"user_id"=>"2"}, "id"=>"1"}

How do I access these variables from a post request.

Thank you.

params[:permission][:user_id]

Thank you...! It works.
