Use gem Recorder for db log 💪

Andrey MorozovBackend Developer at JetRockets

Gem Recorder tracks changes of your Rails models

For start use this library in Rails 5.2 you need add gem to the Gemfile:

 gem 'recorder', github: 'jetrockets/recorder', branch: 'rails_5_2'

 > bundle install > rails g recorder:install > rails db:migrate

And final step -- add to model:

 include ::Recorder::Observer recorder async: false

And it's all 🎉

For an example - logs can be issued in the representer:

 Recorder::Revision.where(item: object).order(id: :DESC).limit(10).map do |revision| { revision_id: revision.id, userId: revision.user_id, userEmail: revision.user&.email, change: changes_type(revision) } end def changes_type(revision) if revision.data['changes'].include?('drive_file_id') && revision.data['changes'].size > 4 && revision.data['changes']['drive_file_id'].present? 'Object updated & Document generated' elsif revision.data['changes'].include?('drive_file_id') && revision.data['changes'].size == 4 'Document generated' elsif revision.data['changes'].include?('number') && revision.data['changes']['number'].nil? 'Object created' else 'Object updated' end end

But of course this is an abstract example with my data 😏
