migration_template(relative_source, relative_destination, template_options = {}) public

When creating a migration, it knows to find the first available file in db/migrate and use the migration.rb template.

# File railties/lib/rails_generator/commands.rb, line 357
        def migration_template(relative_source, relative_destination, template_options = {})
          migration_directory relative_destination
          migration_file_name = template_options[:migration_file_name] || file_name
          raise "Another migration is already named #{migration_file_name}: #{existing_migrations(migration_file_name).first}" if migration_exists?(migration_file_name)
          template(relative_source, "#{relative_destination}/#{next_migration_string}_#{migration_file_name}.rb", template_options)
        end
