Compare with:

except(*keys)

Returns a hash that includes everything except given keys.

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

Parameters
