    <p>I'm trying to develop a bet web page. I have an entity "Apuesta" (bet) and an entity "Partido" (match). An "Apuesta" have a collection of Partido (in the attr $Partidos) and the getter getPartidos() which return the collection. A "Partido" have a type (0 or 1), which specify the fields of his form depending on this value.</p> <p>What I want to get is to include the "Partido" Form into the "Apuesta" Form, but I want that the "Partido" knows itself to render his own Form depending on the $Type value. Obviously, the "Apuesta" is created in the database with his own "Partidos".</p> <p>My code is:</p> <pre><code> class ApuestaForm extends AbstractType{ public function buildForm(FormBuilder $builder, array $options) { $p = $builder-&gt;getData()-&gt;getPartidos(); $builder-&gt;add('Jornada') -&gt;add('Partidos', 'collection', array('type' =&gt; new PartidoForm())); } public function getName(){ return 'ApuestaForm'; } public function getDefaultOptions(array $options) { return array( 'data_class' =&gt; 'A\ApuestaBundle\Entity\Apuesta', ); } } </code></pre> # <pre><code>class PartidoForm extends AbstractType { public function buildForm(FormBuilder $builder, array $options) { **$tipo; //$partido = $builder-&gt;getData(); //$tipo = $partido-&gt;getTipo(); $builder-&gt;add('Local') -&gt;add('Visitante') -&gt;add('Tipo') -&gt;add('Jornada'); if ($tipo == 1){ $builder-&gt;add('some field 1') } else{ $builder-&gt;add('some field 2') } } public function getName(){ return 'PartidoForm'; } public function getDefaultOptions(array $options) { return array( 'data_class' =&gt; 'A\ApuestaBundle\Entity\Partido', ); } } </code></pre> <p>This way, an "Apuesta" render automatically his own "Partidos" and each "Partido" should know if his $Type is 1 or 0. The problem is that $builder->getData() doesn't get the "Partido" entity, but also a null.</p> <p>Another way I thought to do it was to do a contruct with an entity param "Partido", but the problem is that the "Apuesta" Form render a collection of "Partido", so I can't pass a single object "Partido", but also a collection.</p> <p>I tried not to use Form events, because it is a very simple Form.</p> <p>Thanks a lot!</p>

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.
