Sails JS Waterline join of multiple models
In SailsJS 0.10+ you can use model associations to do database joins. You can read more about them here: http://sailsjs.com/documentation/concepts/models-and-orm/associations
Basically you first define an association in your model;
var someModel = { attributes: { name: { type: 'text' } }};var someOtherModel = { attributes: { name: { type: 'text' }, associationProp: { model: 'someModel' } }};In the code above someOtherModel contains association (relation) to someModel. To do a join query you can use .populate() method. For example retrieve all someOtherModel entities and populate associative properties;
someOtherModel.find().populate('associationProp').exec(...);For MySQL and PSQL adapters there's also .query() method available where you can write some hand written SQL queries to be executed (this also works in sails <0.10);
Model.query(<sql query>, <optional data>, callback);
