Rails schema not updating detroit black dating services You can learn more about callbacks in the Active Record Callbacks guide. Rails provides a domain-specific language for managing a database schema called migrations. If you are not using STI, try an analogous keyword like “context”, that may still accurately describe the data you are modeling.

However, if you follow the conventions adopted by Rails, you’ll need to write very little configuration in some cases no configuration at all when creating Active Record models. The idea is that if you configure your applications in the very same way most of the time then this should be the default way.
