# Open rails console `rails c` and run the command:
ActiveRecord::Base.descendants.map(&:name).each { |name| puts name }

# Alternatively, list classes that extend ActiveRecord::Base or any other class the application might use as a base model
ObjectSpace.each_object(Class).select { |klass| klass < ActiveRecord::Base }.map(&:name).sort

# For docker-based apps
docker exec -it [your_container_name] rails runner "ActiveRecord::Base.descendants.each { |model| puts model.name }"
