sails-orientdb

dev:, master:

Provides easy access to orientdb from Sails.js & Waterline.

The adapter in early development stages, pull requests are welcome

The adapter automatically creates edges between model instances with the help of associations information available from Collection instance

This module is a Waterline/Sails adapter, an early implementation of a rapidly-developing, tool-agnostic data standard. Its goal is to provide a set of declarative interfaces, conventions, and best-practices for integrating with all sorts of data sources. Not just databases-- external APIs, proprietary web services, or even hardware.

Strict adherence to an adapter specification enables the (re)use of built-in generic test suites, standardized documentation, reasonable expectations around the API for your users, and overall, a more pleasant development experience for everyone.

Example Model definitions

Development

/**
 * User Model
 *
 * The User model represents the schema of authentication data
 */
module.exports = {

    // Enforce model schema in the case of schemaless databases
    schema: true,
    tableName: 'User',
    attributes: {
        id: {
            type: 'string',
            primaryKey: true,
            columnName: '@rid'
        },
        username: {
            type: 'string',
            unique: true
        },
        email: {
            type: 'email',
            unique: true
        },        
        profile: {
            collection: 'Profile',
            via: 'user',
            edge: 'userProfile'
        }
    }
};

Profile Model to be associated with User model

/**
 * Profile.js
 *
 * @description :: TODO: You might write a short summary of how this model works and what it represents here.
 * @docs        :: http://sailsjs.org/#!documentation/models
 */

module.exports = {
    tableName: 'Profile',
    attributes: {
        id: {
            type: 'string',
            primaryKey: true,
            columnName: '@rid'
        },
        user: {
            model: "User",
            required: true
        },
        familyName: {
            type: 'string'
        },
        givenName: {
            type: 'string'
        },
        profilePic: {
            type: 'string'
        }
    }
};

An edge names userProfile would be created between user and profile model instances whenever an instance of profile model is saved with user attribute having id of user instance.

Check out Connections in the Sails docs, or see the config/connections.js file in a new Sails project for information on setting up adapters.

Sample connection configuration in connection.js

If databas doesn't exist adapter will attempt to create a new one

localOrientDB: {
        adapter: 'sails-orientdb',
        database: {
            name: 'dataBaseName'
        },
        username: "userName",
        password: "password"
        }
