Advanced usage: example with Doctrine

That's not really an advanced topic, but the sample will be a bit hard to read (as it takes many files), so let's say it targets more experienced Symfony users.

In this demo, we're displaying a MyArray of MyElements, both persisted into the database. The MyArray entity only have an id and a name, and MyElement has id, MyArray's id and a value. This is quite the same as we seen in all demos, but persisted.

Array name:
Add an element...

    <p>
        That's not really an <i>advanced</i> topic, but the sample will be a bit hard to read (as it takes many files),
        so let's say it targets more experienced Symfony users.
    </p>

    <p>
        In this demo, we're displaying a MyArray of MyElements, both persisted into the database. The MyArray entity
        only have an id and a name, and MyElement has id, MyArray's id and a value. This is quite the same as we seen
        in all demos, but persisted.
    </p>

    <div class="text-center">
        <input type="button" id="new" class="btn btn-default" value="Create new array"/>
    </div>

    {%
        form_theme form
            'jquery.collection.html.twig'
