Introducing YAMLRecord!
At Miso, we occasionally ran into situations where we wanted to persist simple data to a text (or yaml) file. Examples include landing page email forms, contact us forms, feedback forms, about us “team” page, etc. In these situations, we wanted a way to persist data to YAML and easily view the results in a text file but also manage the data through forms and controllers as any other data. To do this we have created a YAML-backed persistence engine called YAMLRecord for those situations so we can access YAML based data using a familiar ActiveRecord API.
