Ruby: delete multiple hash keys

Returns a hash that includes everything but the given keys.

hash = { a: true, b: false, c: nil}
hash.except(:c) # => { a: true, b: false}
hash # => { a: true, b: false, c: nil}

This is useful for limiting a set of parameters to everything but a few known toggles:

@person.update(params[:person].except(:admin))
