    <p>Here's an automatic solution found in <a href="http://kriswallsmith.net/post/144021872/symfony-denote-required-form-fields" rel="nofollow">Kris Wallsmith's blog</a>:</p> <p>lib/formatter/RequiredLabelsFormatterTable.class.php, this will add a 'required' class to the labels of required fields</p> <pre><code>&lt;?php class RequiredLabelsFormatterTable extends sfWidgetFormSchemaFormatterTable { protected $requiredLabelClass = 'required'; public function generateLabel($name, $attributes = array()) { // loop up to find the "required_fields" option $widget = $this-&gt;widgetSchema; do { $requiredFields = (array) $widget-&gt;getOption('required_fields'); } while ($widget = $widget-&gt;getParent()); // add a class (non-destructively) if the field is required if (in_array($this-&gt;widgetSchema-&gt;generateName($name), $requiredFields)) { $attributes['class'] = isset($attributes['class']) ? $attributes['class'].' '.$this-&gt;requiredLabelClass : $this-&gt;requiredLabelClass; } return parent::generateLabel($name, $attributes); } } </code></pre> <p>lib/form/BaseForm.class.php, this is the common base class for all the forms in your project:</p> <pre><code> protected function getRequiredFields(sfValidatorSchema $validatorSchema = null, $format = null) { if (is_null($validatorSchema)) { $validatorSchema = $this-&gt;validatorSchema; } if (is_null($format)) { $format = $this-&gt;widgetSchema-&gt;getNameFormat(); } $fields = array(); foreach ($validatorSchema-&gt;getFields() as $name =&gt; $validator) { $field = sprintf($format, $name); if ($validator instanceof sfValidatorSchema) { // recur $fields = array_merge( $fields, $this-&gt;getRequiredFields($validator, $field.'[%s]') ); } else if ($validator-&gt;getOption('required')) { // this field is required $fields[] = $field; } } return $fields; } </code></pre> <p>add the following few lines to BaseForm as well, in the <code>__construct()</code> method:</p> <pre><code>$this-&gt;widgetSchema-&gt;addOption("required_fields", $this-&gt;getRequiredFields()); $this-&gt;widgetSchema-&gt;addFormFormatter('table', new RequiredLabelsFormatterTable($this-&gt;widgetSchema) ); </code></pre> <p>After all this, all your labels will have the <code>required</code> class, use whatever css you need to mark it to the user.</p>

    1. CO+1 good solution; think I saw this or similar on Kris Wallsmith's blog. Dead easy to use. You can add the last snippet into eg `BaseFormDoctrine::__construct(...)` as well - that way all your model forms can use it automatically.

Querying!

 
Guidance
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).
