You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: column.rb
    path of file: ./repos/mobility/lib/mobility/backends/sequel
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
    
      def get_column_locales
        column_name_regex = /\A#{attribute}_([a-z]{2}(_[a-z]{2})?)\z/.freeze
        model.columns.map do |c|
          (match = c.to_s.match(column_name_regex)) && match[1].to_sym
        end.compact
      end
    end
