    <p>After loading TWIG, add this filter:</p> <pre><code>$twig-&gt;addFilter( new Twig_SimpleFilter('cast_to_array', function ($stdClassObject) { $response = array(); foreach ($stdClassObject as $key =&gt; $value) { $response[] = array($key, $value); } return $response; })); </code></pre> <p>It's named <strong>cast_to_array</strong> after <a href="https://stackoverflow.com/users/548696/tadeck">Tadeck</a>'s suggestion. :) I'm sure it doesn't work for any kind of <em>stdClass Object</em>, but it sure solved my problem with printing PHP <em>associative arrays</em> :) Use it as follows:</p> <pre><code>{% for key, value in my_object|cast_to_array %} &lt;td&gt;{{ value.1 }}&lt;/td&gt; {% endfor %} </code></pre> <h1>Side story</h1> <p>Since I got into this SO page a lot, I think it's pertinent to show where I'm using Twig for <em>iterating over object properties</em>, so it's helpful for other people with the same problem: I was trying to print a table from a .json source, but PHP's json_decode transforms any <em>"key" : "value"</em> into a PHP associative array, which Twig doesn't print by default. So this filter cuts and delivers a regular array to be used by Twig.</p> <h2>source.json</h2> <pre><code>{ "user": { "family": { "table": [{ "First_Name": "John", "Last_Name": "Foo", "Age": 25, "Role": "Brother" }, { "First_Name": "Mary", "Last_Name": "Bar", "Age": 14, "Role": "Sister" }, { "First_Name": "Joe", "Last_Name": "Baz", "Age": 33, "Role": "Uncle" }] } } } </code></pre> <h2>Twig</h2> <pre><code>&lt;table&gt; &lt;thead&gt; &lt;tr&gt; {# get table headers from the table row #} {% for row in user.family.table.0|cast_to_array %} &lt;th&gt;{{ row.0 | replace({'_': ' '}) }}&lt;/th&gt; {% endfor %} &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; {% for row in user.family.table %} &lt;tr&gt; {% for key, value in row|cast_to_array %} &lt;td&gt;{{ value.1 }}&lt;/td&gt; {% endfor %} &lt;/tr&gt; {% endfor %} &lt;/tbody&gt; &lt;/table&gt; </code></pre>

    1. COIs there a reason you don't just do: $twig->addFilter(new Twig_SimpleFilter('cast_to_array', function ($stdClassObject) { return (array)$stdClassObject; }));

    2. COObjects can be iterated just like arrays, Twig should provide the functionality, instead of taking it away and forcing unnecessary data massaging.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
