To use MySQL/MongoDB, first you need to install adapter for it

  • Install sails-mysql adapter using npm

    npm install sails-mysql --save

You can configure DB in config/connections.js

      mongoDB: {
                          adapter: 'sails-mongo',
                          host: 'localhost',
                          port: 27017,
                          user: '', //optional
                          password: '', //optional
                          database: 'my_mongo' //optional

           adapter: 'sails-mysql',
           host: 'localhost',
           user: 'root', //optional
           password: 'root', //optional
           database: 'sailsit' //optional


4. Model Configuration

You can configure database to be used by model at global level (for all models) or at specific model level

    • Configuring DB at global level
      Define DB connection name in config/models.js

      connection: 'mongoDB' //This name should be exactly same as defined in config/connections.js


  • Configuring DB at model level
    Define DB connection at specific model in api/models/YourModel.js

    module.exports = {
        connection: 'mongoDB',
