Hey All, I've recently switched from using ActiveRecord to DataMapper and the minor differences have made it a smooth transition so far. However, I can't seem to find any documentation on maintaining a counter. I have an integer column in my model that needs to be incremented periodically. My first inclination was to use model.update_attributes (), but this seems to be a bad idea because the database value could be overwritten before DataMapper can write. The SQL query:
UPDATE table_name SET counter = counter + 1 WHERE id = n; accomplishes what I want to do. I've perused the DataMapper code and docs, but I can't seem to find a method that will abstract this. ActiveRecord's is called 'increment_counter'. Am I missing the simple way to do this?
