By default, new Sails apps are bundled with an ORM called Waterline (implemented in the sails-hook-orm dependency).
To learn more about using Waterline, start in Concepts > Models & ORM.
This section of the documentation contains a reference of all of the methods available at runtime on models, queries, and datastores.
If you notice something we've missed or could be improved on, please follow this link and submit a pull request to the sails repo. Once we merge it, the changes will be reflected on the website the next time it is deployed.
