We are trying to upgrade to hanami 1.3.2, which in turn is making us upgrade Transproc to 1.1.0. We have some mappers which relied on Transformer class methods being available with on declaration, but now we are getting
undefined method errors.
# test.rb require 'bundler/inline' gemfile do source "https://rubygems.org" gem "rom" # doesnt work on 1.1.0 gem "transproc", ENV.fetch('TRANSPROC_VERSION') end require 'rom/transformer' class ProductMapper < ROM::Transformer class << self def prepare(value) value.to_s.strip end end map_array do map_value :name, method(:prepare) end end puts ProductMapper.new.call([name: ' test '])
To illustrate the issue, run the following commands:
TRANSPROC_VERSION=1.0.2 rb test.rb # this works
TRANSPROC_VERSION=1.1.0 rb test.rb # this does not work
What is the best pattern for defining methods in a Transformer which can be used in declarations? i.e. how could I refactor the above code to work on 1.1.0?
Thank you for your hard work and time
