So before we had the following:
$form = $this->get('fos_user.form.user');
$form->setValidationGroups(array(Registration));
<service id="fos_user.form.user" class="%fos_user.form.user.class%">
<argument>%fos_user.form.user.name%</argument>
<argument></argument>
<argument type="service" id="validator" />
<argument type="collection">
<argument key="theme">%fos_user.template.theme%</argument>
</argument>
</service>
Now I would want to do the following, notice the setClass() method which sets
the class to use in FormContext::getForm() and setName() which allows me to
just use getForm($data = null) in my code, allowing me to set the name via the
DIC.
$form = $this->get('fos_user.form.user_factory')
->validationGroups(array(Registration)
->getForm();
<service id="fos_user.form.user_factory" factory-service="form_factory"
factory-method="setName" shared="false">
<argument>%fos_user.form.user.name%</argument>
<call method="setClass">
<argument>%fos_user.form.user.class%</argument>
</call>
<call method="setOption">
<argument type="collection">
<argument key="theme">%fos_user.template.theme%</argument>
</argument>
</call>
</service>
Note I am a bit unsure why the setters in the FormFactory() do not have a set
prefix.
