class Hash
# Return a hash that includes everything but the given keys. This is useful for
# limiting a set of parameters to everything but a few known toggles:
#
# @person.update_attributes(params[:person].except(:admin))
#
# If the receiver responds to +convert_key+, the method is called on each of the
# arguments. This allows +except+ to play nice with hashes with indifferent access
# for instance:
#
# {:a => 1}.with_indifferent_access.except(:a) # => {}
# {:a => 1}.with_indifferent_access.except("a") # => {}
#
def except(*keys)
dup.except!(*keys)
end
# Replaces the hash without the given keys.
def except!(*keys)
keys.each { |key| delete(key) }
self
end
