Body
I'm using Symfony's 1.4 admin generator, and I have a question about a one to many relationship. If A has many B and B one A, I will see a listbox when editing B, that's ok, but I have to add a list (with multiple choices) of B when I edit an A. I have a solution but I don't no if it is the right way : I have modified the A form this way : <pre><code>class AForm extends BaseAForm { public function configure() { $this->widgetSchema['b_list'] = new sfWidgetFormDoctrineChoice(array('multiple' => true, 'model' => 'B')); $this->validatorSchema['b_list'] = new sfValidatorDoctrineChoice(array('multiple' => true, 'model' => 'B', 'required' => false)); } public function updateDefaultsFromObject() { parent::updateDefaultsFromObject(); if (isset($this->widgetSchema['b_list'])) { $this->setDefault('b_list', $this->object->B->getPrimaryKeys()); } } protected function doSave($con = null) { $this->saveBsList($con); parent::doSave($con); } public function saveBsList($con = null) { if (!$this->isValid()) { throw $this->getErrorSchema(); } if (!isset($this->widgetSchema['b_list'])) { // somebody has unset this widget return; } if (null === $con) { $con = $this->getConnection(); } $existing = $this->object-Bs->getPrimaryKeys(); $values = $this->getValue('b_list'); if (!is_array($values)) { $values = array(); } $unlink = array_diff($existing, $values); if (count($unlink)) { $this->object->unlink('Bs', array_values($unlink)); } $link = array_diff($values, $existing); if (count($link)) { $this->object->link('Bs', array_values($link)); } } } </code></pre> I use the same code which is generated for a many-to-namy relation. Is there a better way ? Thanks Edit : The schema <pre><code>Agency: columns: id: type: integer(4) primary: true autoincrement: true name: { type: string(255), notnull: true } relations: Consultants: refClass: Consultant Consultant: columns: if: type: integer(4) primary: true autoincrement: true name: { type: string(255), notnull: true } ref_agency: integer(4) relations: Agence: foreignAlias: Agencies local: ref_agency foreign: id class: Agency </code></pre>

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.
