betajs-data 1.0.184

BetaJS-Data is a general-purpose JavaScript framework for handling RESTful operations and ActiveRecord abstractions.

Getting Started

You can use the library in the browser, in your NodeJS project and compile it as well.

Browser

	<script src="betajs/dist/betajs.min.js"></script>
	<script src="betajs-data/dist/betajs-data.min.js"></script>

NodeJS

	var BetaJS = require('betajs/dist/beta.js');
	require('betajs-data/dist/betajs-data.js');

Compile

	git clone https://github.com/betajs/betajs-data.git
	npm install
	grunt

Basic Usage

The BetaJS Data module contains the following subsystems:

• Query Engine
• Data Store System
• Model / Table System
• Data-based Collections

Queries

  {
    "gender": "male",
    "age": {
      "$gt": 16
    },
    "first_name": {
      "$sw": "S"
    }
  }

  evaluate(query, {"gender": "female", ...}) === false
  evaluate(query, {"age": 16, ...}) === false
  evaluate(query, {"first_name": "Guybrush", ...}) === false
  evaluate(query, {"gender": "male", "age": 17, "first_name": "Simon"}) === true

Data Stores

   store.insert(instance).success(function (data) {
     // Instance was inserted, and the updated data of instance is data (including the id)
   }).error(function (error) {
     // Could not insert instance
   });

   store.query(query, constraints).success(function (iterator) {
     // Store was succesfully queried; the query result is an iterator over matched instances.
   }).error(function (error) {
     // Could not execute query
   });

Modelling

   var MyModel = BetaJS.Data.Modelling.Model.extend(null, {
   }, function (inherited) {
        return {
            _initializeScheme: function () {
                var scheme = inherited._initializeScheme.call(this);
                scheme.first_name = {
                    type: "string"
                };
                scheme.last_name = {
                    type: "string"
                };
                return scheme;
           }
        };
   });

   var myTable = new BetaJS.Data.Modelling.Table(store, MyModel);

Query Collections

   var tableQC = new BetaJS.Data.Collections.TableQueryCollection(table, query, options);
   var storeQC = new BetaJS.Data.Collections.StoreQueryCollection(store, query, options);
