+ * @class Ext.data.Model
+ *
+ * <p>A Model represents some object that your application manages. For example, one might define a Model for Users, Products,
+ * Cars, or any other real-world object that we want to model in the system. Models are registered via the {@link Ext.ModelManager model manager},
+ * and are used by {@link Ext.data.Store stores}, which are in turn used by many of the data-bound components in Ext.</p>
+ *
+ * <p>Models are defined as a set of fields and any arbitrary methods and properties relevant to the model. For example:</p>
+ *
+<pre><code>
+Ext.define('User', {
+ extend: 'Ext.data.Model',
+ fields: [
+ {name: 'name', type: 'string'},
+ {name: 'age', type: 'int'},
+ {name: 'phone', type: 'string'},
+ {name: 'alive', type: 'boolean', defaultValue: true}
+ ],
+
+ changeName: function() {
+ var oldName = this.get('name'),
+ newName = oldName + " The Barbarian";
+
+ this.set('name', newName);
+ }
+});
+</code></pre>
+*
+* <p>The fields array is turned into a {@link Ext.util.MixedCollection MixedCollection} automatically by the {@link Ext.ModelManager ModelManager}, and all
+* other functions and properties are copied to the new Model's prototype.</p>
+*
+* <p>Now we can create instances of our User model and call any model logic we defined:</p>
+*
+<pre><code>
+var user = Ext.ModelManager.create({
+ name : 'Conan',
+ age : 24,
+ phone: '555-555-5555'
+}, 'User');
+
+user.changeName();
+user.get('name'); //returns "Conan The Barbarian"
+</code></pre>
+ *
+ * <p><u>Validations</u></p>
+ *
+ * <p>Models have built-in support for validations, which are executed against the validator functions in
+ * {@link Ext.data.validations} ({@link Ext.data.validations see all validation functions}). Validations are easy to add to models:</p>
+ *
+<pre><code>
+Ext.define('User', {
+ extend: 'Ext.data.Model',
+ fields: [
+ {name: 'name', type: 'string'},
+ {name: 'age', type: 'int'},
+ {name: 'phone', type: 'string'},
+ {name: 'gender', type: 'string'},
+ {name: 'username', type: 'string'},
+ {name: 'alive', type: 'boolean', defaultValue: true}
+ ],
+
+ validations: [
+ {type: 'presence', field: 'age'},
+ {type: 'length', field: 'name', min: 2},
+ {type: 'inclusion', field: 'gender', list: ['Male', 'Female']},
+ {type: 'exclusion', field: 'username', list: ['Admin', 'Operator']},
+ {type: 'format', field: 'username', matcher: /([a-z]+)[0-9]{2,3}/}
+ ]
+});
+</code></pre>
+ *
+ * <p>The validations can be run by simply calling the {@link #validate} function, which returns a {@link Ext.data.Errors}
+ * object:</p>
+ *
+<pre><code>
+var instance = Ext.ModelManager.create({
+ name: 'Ed',
+ gender: 'Male',
+ username: 'edspencer'
+}, 'User');
+
+var errors = instance.validate();
+</code></pre>
+ *
+ * <p><u>Associations</u></p>
+ *
+ * <p>Models can have associations with other Models via {@link Ext.data.BelongsToAssociation belongsTo} and
+ * {@link Ext.data.HasManyAssociation hasMany} associations. For example, let's say we're writing a blog administration
+ * application which deals with Users, Posts and Comments. We can express the relationships between these models like this:</p>
+ *
+<pre><code>
+Ext.define('Post', {
+ extend: 'Ext.data.Model',
+ fields: ['id', 'user_id'],
+
+ belongsTo: 'User',
+ hasMany : {model: 'Comment', name: 'comments'}
+});
+
+Ext.define('Comment', {
+ extend: 'Ext.data.Model',
+ fields: ['id', 'user_id', 'post_id'],
+
+ belongsTo: 'Post'
+});
+
+Ext.define('User', {
+ extend: 'Ext.data.Model',
+ fields: ['id'],
+
+ hasMany: [
+ 'Post',
+ {model: 'Comment', name: 'comments'}
+ ]
+});
+</code></pre>
+ *
+ * <p>See the docs for {@link Ext.data.BelongsToAssociation} and {@link Ext.data.HasManyAssociation} for details on the usage
+ * and configuration of associations. Note that associations can also be specified like this:</p>
+ *
+<pre><code>
+Ext.define('User', {
+ extend: 'Ext.data.Model',
+ fields: ['id'],
+
+ associations: [
+ {type: 'hasMany', model: 'Post', name: 'posts'},
+ {type: 'hasMany', model: 'Comment', name: 'comments'}
+ ]
+});
+</code></pre>
+ *
+ * <p><u>Using a Proxy</u></p>
+ *
+ * <p>Models are great for representing types of data and relationships, but sooner or later we're going to want to
+ * load or save that data somewhere. All loading and saving of data is handled via a {@link Ext.data.proxy.Proxy Proxy},
+ * which can be set directly on the Model:</p>
+ *
+<pre><code>
+Ext.define('User', {
+ extend: 'Ext.data.Model',
+ fields: ['id', 'name', 'email'],
+
+ proxy: {
+ type: 'rest',
+ url : '/users'
+ }
+});
+</code></pre>
+ *
+ * <p>Here we've set up a {@link Ext.data.proxy.Rest Rest Proxy}, which knows how to load and save data to and from a
+ * RESTful backend. Let's see how this works:</p>
+ *
+<pre><code>
+var user = Ext.ModelManager.create({name: 'Ed Spencer', email: 'ed@sencha.com'}, 'User');
+
+user.save(); //POST /users
+</code></pre>
+ *
+ * <p>Calling {@link #save} on the new Model instance tells the configured RestProxy that we wish to persist this
+ * Model's data onto our server. RestProxy figures out that this Model hasn't been saved before because it doesn't
+ * have an id, and performs the appropriate action - in this case issuing a POST request to the url we configured
+ * (/users). We configure any Proxy on any Model and always follow this API - see {@link Ext.data.proxy.Proxy} for a full
+ * list.</p>
+ *
+ * <p>Loading data via the Proxy is equally easy:</p>
+ *
+<pre><code>
+//get a reference to the User model class
+var User = Ext.ModelManager.getModel('User');
+
+//Uses the configured RestProxy to make a GET request to /users/123
+User.load(123, {
+ success: function(user) {
+ console.log(user.getId()); //logs 123
+ }
+});
+</code></pre>
+ *
+ * <p>Models can also be updated and destroyed easily:</p>
+ *
+<pre><code>
+//the user Model we loaded in the last snippet:
+user.set('name', 'Edward Spencer');
+
+//tells the Proxy to save the Model. In this case it will perform a PUT request to /users/123 as this Model already has an id
+user.save({
+ success: function() {
+ console.log('The User was updated');
+ }
+});
+
+//tells the Proxy to destroy the Model. Performs a DELETE request to /users/123
+user.destroy({
+ success: function() {
+ console.log('The User was destroyed!');
+ }
+});
+</code></pre>
+ *
+ * <p><u>Usage in Stores</u></p>
+ *
+ * <p>It is very common to want to load a set of Model instances to be displayed and manipulated in the UI. We do this
+ * by creating a {@link Ext.data.Store Store}:</p>
+ *
+<pre><code>
+var store = new Ext.data.Store({
+ model: 'User'
+});
+
+//uses the Proxy we set up on Model to load the Store data
+store.load();
+</code></pre>
+ *
+ * <p>A Store is just a collection of Model instances - usually loaded from a server somewhere. Store can also maintain
+ * a set of added, updated and removed Model instances to be synchronized with the server via the Proxy. See the
+ * {@link Ext.data.Store Store docs} for more information on Stores.</p>
+ *
+ * @constructor
+ * @param {Object} data An object containing keys corresponding to this model's fields, and their associated values
+ * @param {Number} id Optional unique ID to assign to this model instance
