Thanks, but I still don't understand what is being submitted. Is it a
hash, an array of arrays, or what? For example, what would the syntax
be to retrieve the approval value of user "4"?
Parameters: {"commit"=>"Submit", "user"=>{"6"=>{"approval"=>"1"},
"1"=>{"approval"=>"1"}, "2"=>{"approval"=>"2"}, "3"=>
{"approval"=>"2"}, "4"=>{"approval"=>"2"}, "5"=>{"approval"=>"2"}},
"authenticity_token"=>"39757ec52a8cb0e04a7533686976d49388378c02",
"_method"=>"put", "action"=>"approve", "controller"=>"admin/users"}
