module BootstrapForm
# This module implements the old ActiveSupport alias_method_chain feature
# with a new name, and without the deprecation warnings. In ActiveSupport 5+,
# this style of patching was deprecated in favor of Module.prepend. But
# Module.prepend is not present in Ruby 1.9, which we would still like to
# support. So we continue to use of alias_method_chain, albeit with a
# different name to avoid collisions.
module Aliasing
# This code is copied and pasted from ActiveSupport, but with :bootstrap
# hardcoded as the feature name, and with the deprecation warning removed.
def bootstrap_method_alias(target)
feature = :bootstrap
# Strip out punctuation on predicates, bang or writer methods since
# e.g. target?_without_feature is not a valid method name.
aliased_target, punctuation = target.to_s.sub(/([?!=])$/, ''), $1
