You have some great suggestions about using the .update method from
others. Just to answer your direct question here - Ruby represents
hashes with braces, so where you see those braces in the output from
your log that you've pasted in - that's a hash (actually a hash of
hashes). Ie. { "foo" => "bar" } is a hash with one member with the
key of "foo" and the value of "bar" and { "foo" => { "foo" =>
"bar" } } is a hash with one member and the value of that member is
another hash with one member.
I actually gave you the syntax for accessing the values in my last
post, but explicitly for user "4" you would use params[:user][:'4']
[:approval] to get it (btw, you can use symbols or strings because
Rails converts the params hash to a different object that allows
access using either).
