<h1 id="Cookbook..Form">Cookbook: Form</h1>
<div class="cookbook--form"><p>A web application's main purpose is to present and gather data. For this reason angular strives
to make both of these operations trivial. This example shows off how you can build a simple form to
allow a user to enter data.</p>

<h2>Things to notice</h2>

<ul>
<li>The user data model is initialized <a href="api/angular.module.ng.$compileProvider.directive.ngController"><code>controller</code></a> and is
available in the <a href="api/angular.module.ng.$rootScope.Scope"><code>scope</code></a> with the initial data.</li>
<li>For debugging purposes we have included a debug view of the model to better understand what
is going on.</li>
<li>The <a href="api/angular.module.ng.$compileProvider.directive.input"><code>input directives</code></a> simply refer
to the model and are data-bound.</li>
<li>The inputs <a href="guide/dev_guide.forms">validate</a>. (Try leaving them blank or entering non digits
in the zip field)</li>
<li>In your application you can simply read from or write to the model and the form will be updated.</li>
<li>By clicking the 'add' link you are adding new items into the <code>user.contacts</code> array which are then
reflected in the view.</li>
</ul></div>
