PersistenceJs Example with AngularJS Factory.

gistfile1.js

// Task.js
var app = angular.module('MyApp');
app.factory('Task', function () {
    // Hacer un ejeemplo con t odo para depues re-factorizar.
    //console.debug(persistence.store.websql);
    persistence.store.websql.config(persistence, 'MyTask', 'A database description', 5 * 1024 * 1024);

    var Task = persistence.define('Task', {
        name: "TEXT",
        description: "TEXT",
        done: "BOOL"
    });

    Task.prototype.getResume = function (){
        return this.id + " " + this.name + " " + this.description + " " + this.done;
    };

    persistence.schemaSync();
    return Task;
});

// Comment.js
'use strict';

var app = angular.module('MyApp')
app.factory('Comment', function (Task) {
    var Comment = persistence.define('Comment', {
        text : 'TEXT'
    });
    Task.hasMany('comments', Comment, 'task');
    return Comment;
});


// Example.js
var app = angular.module('MyApp');
app.controller('PersistenceCtrl', function ($scope, Task, Comment) {
    $scope.click = function (){
        var tarea = new Task();
        //tarea.id = 1;
        tarea.name = "asdsad";
        tarea.description = "descripcion";
        tarea.done = true;

        var comentario = new Comment();
        comentario.text = 'lalaala';
        tarea.comments.add(comentario);
        console.debug(tarea.getResume());

        persistence.add(tarea);

        persistence.flush(function() {
            console.debug('Done flushing');
        });
    }

    $scope.recover = function () {
        console.log('asdasdasd');
        //console.log();
        Task.all().filter('id', '=', 1).list(null, function(result){
            console.log(result);
        });
    };
});

Hi, after few tries with persistence.js I discovered the problem, that you cannot put your model object directly to any angular directive, as it have circular reference.
