rails-generators

I need to override these migration templates: https://github.com/rails/rails/blob/e20dd73df42d63b206d221e2258cc6dc7b1e6068/activerecord/lib/rails/generators/active_record/migration/templates/migration.rb and https://github.com/rails/rails/blob/e20dd73df42d63b206d221e2258cc6dc7b1e6068/activerecord/lib/rails/generators/active_record/migration/templates/create_table_migration.rb inside my rails application so that they pick up the template from rails application instead of the gem itself. I've tried all possible combinations so far but no luck. What I've tried: - Rails.root/lib/templates/rails
