<h2>What is a model?</h2>
<p>Across the internet the definition of <a href="http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller"><span class="caps">MVC</span></a> is so diluted that it’s hard to tell what exactly your model should be doing. The authors of backbone.js have quite a clear definition of what they believe the model represents in backbone.js.</p>
<blockquote>
<p>Models are the heart of any JavaScript application, containing the interactive data as well as a large part of the logic surrounding it: conversions, validations, computed properties, and access control.</p>
</blockquote>
<p>So for the purpose of the tutorial let’s create a model.</p>
<div class="highlight"><pre><code class="javascript"> <span class="nx">Person</span> <span class="o">=</span> <span class="nx">Backbone</span><span class="p">.</span><span class="nx">Model</span><span class="p">.</span><span class="nx">extend</span><span class="p">({</span>
<span class="nx">initialize</span><span class="o">:</span> <span class="kd">function</span><span class="p">(){</span>
<span class="nx">alert</span><span class="p">(</span><span class="s2">"Welcome to this world"</span><span class="p">);</span>
<span class="p">}</span>
<span class="p">});</span>
<span class="kd">var</span> <span class="nx">person</span> <span class="o">=</span> <span class="k">new</span> <span class="nx">Person</span><span class="p">;</span>
</code></pre>
</div>
<p>So <em>initialize()</em> is triggered whenever you create a new instance of a model( models, collections and views work the same way ). You don’t have to include it in your model declaration but you will find yourself using it more often than not.</p>
<h4>Setting attributes</h4>
<p>Now we want to pass some parameters when we create an instance of our model.</p>
<div class="highlight"><pre><code class="javascript"> <span class="nx">Person</span> <span class="o">=</span> <span class="nx">Backbone</span><span class="p">.</span><span class="nx">Model</span><span class="p">.</span><span class="nx">extend</span><span class="p">({</span>
<span class="nx">initialize</span><span class="o">:</span> <span class="kd">function</span><span class="p">(){</span>
<span class="nx">alert</span><span class="p">(</span><span class="s2">"Welcome to this world"</span><span class="p">);</span>
<span class="p">}</span>
<span class="p">});</span>
<span class="kd">var</span> <span class="nx">person</span> <span class="o">=</span> <span class="k">new</span> <span class="nx">Person</span><span class="p">({</span> <span class="nx">name</span><span class="o">:</span> <span class="s2">"Thomas"</span><span class="p">,</span> <span class="nx">age</span><span class="o">:</span> <span class="mi">67</span><span class="p">});</span>
<span class="k">delete</span> <span class="nx">person</span><span class="p">;</span>
<span class="c1">// or we can set afterwards, these operations are equivelent</span>
<span class="kd">var</span> <span class="nx">person</span> <span class="o">=</span> <span class="k">new</span> <span class="nx">Person</span><span class="p">();</span>
<span class="nx">person</span><span class="p">.</span><span class="nx">set</span><span class="p">({</span> <span class="nx">name</span><span class="o">:</span> <span class="s2">"Thomas"</span><span class="p">,</span> <span class="nx">age</span><span class="o">:</span> <span class="mi">67</span><span class="p">});</span>
</code></pre>
</div>
<p>So passing a javascript object to our constructor is the same as calling <em>model.set()</em>. Now that these models have attributes set we need to be able to retrieve them.</p>
<h4>Getting attributes</h4>
<p>Using the <em>model.get()</em> method we can access model properties at anytime.</p>
<div class="highlight"><pre><code class="javascript"> <span class="nx">Person</span> <span class="o">=</span> <span class="nx">Backbone</span><span class="p">.</span><span class="nx">Model</span><span class="p">.</span><span class="nx">extend</span><span class="p">({</span>
<span class="nx">initialize</span><span class="o">:</span> <span class="kd">function</span><span class="p">(){</span>
<span class="nx">alert</span><span class="p">(</span><span class="s2">"Welcome to this world"</span><span class="p">);</span>
<span class="p">}</span>
<span class="p">});</span>
<span class="kd">var</span> <span class="nx">person</span> <span class="o">=</span> <span class="k">new</span> <span class="nx">Person</span><span class="p">({</span> <span class="nx">name</span><span class="o">:</span> <span class="s2">"Thomas"</span><span class="p">,</span> <span class="nx">age</span><span class="o">:</span> <span class="mi">67</span><span class="p">,</span> <span class="nx">children</span><span class="o">:</span> <span class="p">[</span><span class="s1">'Ryan'</span><span class="p">]});</span>
<span class="kd">var</span> <span class="nx">age</span> <span class="o">=</span> <span class="nx">person</span><span class="p">.</span><span class="nx">get</span><span class="p">(</span><span class="s2">"age"</span><span class="p">);</span> <span class="c1">// 67</span>
<span class="kd">var</span> <span class="nx">name</span> <span class="o">=</span> <span class="nx">person</span><span class="p">.</span><span class="nx">get</span><span class="p">(</span><span class="s2">"name"</span><span class="p">);</span> <span class="c1">// "Thomas"</span>
<span class="kd">var</span> <span class="nx">children</span> <span class="o">=</span> <span class="nx">person</span><span class="p">.</span><span class="nx">get</span><span class="p">(</span><span class="s2">"children"</span><span class="p">);</span> <span class="c1">// ['Ryan']</span>
</code></pre>
</div>
<h4>Setting model defaults</h4>
<p>Sometimes you will want your model to contain default values. This can easily be accomplished by setting a property name ‘defaults’ in your model declaration.</p>
<div class="highlight"><pre><code class="javascript"> <span class="nx">Person</span> <span class="o">=</span> <span class="nx">Backbone</span><span class="p">.</span><span class="nx">Model</span><span class="p">.</span><span class="nx">extend</span><span class="p">({</span>
<span class="nx">defaults</span><span class="o">:</span> <span class="p">{</span>
<span class="nx">name</span><span class="o">:</span> <span class="s1">'Fetus'</span><span class="p">,</span>
<span class="nx">age</span><span class="o">:</span> <span class="mi">0</span><span class="p">,</span>
<span class="nx">children</span><span class="o">:</span> <span class="p">[]</span>
<span class="p">},</span>
<span class="nx">initialize</span><span class="o">:</span> <span class="kd">function</span><span class="p">(){</span>
<span class="nx">alert</span><span class="p">(</span><span class="s2">"Welcome to this world"</span><span class="p">);</span>
<span class="p">}</span>
<span class="p">});</span>
<span class="kd">var</span> <span class="nx">person</span> <span class="o">=</span> <span class="k">new</span> <span class="nx">Person</span><span class="p">({</span> <span class="nx">name</span><span class="o">:</span> <span class="s2">"Thomas"</span><span class="p">,</span> <span class="nx">age</span><span class="o">:</span> <span class="mi">67</span><span class="p">,</span> <span class="nx">children</span><span class="o">:</span> <span class="p">[</span><span class="s1">'Ryan'</span><span class="p">]});</span>
<span class="kd">var</span> <span class="nx">age</span> <span class="o">=</span> <span class="nx">person</span><span class="p">.</span><span class="nx">get</span><span class="p">(</span><span class="s2">"age"</span><span class="p">);</span> <span class="c1">// 67</span>
<span class="kd">var</span> <span class="nx">name</span> <span class="o">=</span> <span class="nx">person</span><span class="p">.</span><span class="nx">get</span><span class="p">(</span><span class="s2">"name"</span><span class="p">);</span> <span class="c1">// "Thomas"</span>

<h4>Manipulating model attributes</h4>
<p>Models can contain as many custom methods as you like to manipulate attributes. By default all methods are public.</p>
<div class="highlight"><pre><code class="javascript"> <span class="nx">Person</span> <span class="o">=</span> <span class="nx">Backbone</span><span class="p">.</span><span class="nx">Model</span><span class="p">.</span><span class="nx">extend</span><span class="p">({</span>

<span class="p">},</span>
<span class="nx">initialize</span><span class="o">:</span> <span class="kd">function</span><span class="p">(){</span>
<span class="nx">alert</span><span class="p">(</span><span class="s2">"Welcome to this world"</span><span class="p">);</span>
<span class="p">},</span>

</div>
<p>So we can implement methods to get/set and perform other calculations using attributes from our model at any time.</p>
<h4>Listening for changes to the model</h4>
<p>Now onto one of the more useful parts of using a library such as backbone. All attributes of a model can have listeners bound to them to detect changes to their values. In our initialize function we are going to bind a function call everytime we change the value of our attribute. In this case if the name of our “person” changes we will alert their new name.</p>
<div class="highlight"><pre><code class="javascript"> <span class="nx">Person</span> <span class="o">=</span> <span class="nx">Backbone</span><span class="p">.</span><span class="nx">Model</span><span class="p">.</span><span class="nx">extend</span><span class="p">({</span>

<span class="p">});</span>
<span class="p">},</span>
<span class="nx">replaceNameAttr</span><span class="o">:</span> <span class="kd">function</span><span class="p">(</span> <span class="nx">name</span> <span class="p">){</span>

<span class="kd">var</span> <span class="nx">person</span> <span class="o">=</span> <span class="k">new</span> <span class="nx">Person</span><span class="p">({</span> <span class="nx">name</span><span class="o">:</span> <span class="s2">"Thomas"</span><span class="p">,</span> <span class="nx">age</span><span class="o">:</span> <span class="mi">67</span><span class="p">,</span> <span class="nx">children</span><span class="o">:</span> <span class="p">[</span><span class="s1">'Ryan'</span><span class="p">]});</span>

</code></pre>
</div>
<p>So we can bind the a change listener to individual attributes or if we like simply ‘<em>this.bind(“change”, function(){});</em>’ to listen for changes to all attributes of the model.</p>
<h4>Fetching, Saving and Destroying</h4>
<p>Models actually have to be a part of a collection for requests to the server to work by default. This tutorial is more of a focus on individual models. Check back soon for a tutorial on collection implementation.</p>
<h4>Tips and Tricks</h4>
