I will plan on covering FineUploader with a Shrine series. Thank you for the suggestion.
Great question. It really depends on the complexity to which you've modified the datatables. If you are using server side data and a full text engine, then I would store the 'yes' and 'no' values as part of the indexed data.
If you're using Rails 5.1.x then you could also use a virtual attribute to search on instead of the integer column.
You can check out https://www.driftingruby.com/episodes/virtual-columns-in-mysql and https://www.driftingruby.com/episodes/virtual-columns-with-json-data-types on Virtual Columns.
What environment are you working in?
It is a Rails application, so you would need to have Ruby installed. Check out https://www.driftingruby.com/episodes/getting-started-ruby-on-rails-development-environment on getting a non-system ruby installed on your environment.
Then in the app root, you should be able to just do
gem install bundler #installs bundle cli
bundle # installs gem dependencies
rake db:migrate # creates the SQLite3 Schema
rails s # starts the development server
