php - How do I retrieve the underlying entity object from a Twig template in a Symfony2 entity field?

Question

I have a form builder which creates a form with an 'entity' field type (let's call that entity MyBundle:MyEntity). MyEntity has a property entitled 'description'. In addition to the __tostring() method automatically called by Symfony2 that is used for the label of each radio button, I'd like to access the description property.

I've overridden the choice_widget block and attempted to get {{ child.vars.value }}, but that's just the ID of the entity rather than the object itself.

Does anyone know how to do this, or if it is even possible?

我不太了解您到底想做什么，因为您没有提供任何代码，但据我了解，您想访问孩子的对象，对吗？

如果是这种情况，您可以使用 child.get('value') 这将返回对象

这意味着您可以调用 child.get('value').getDescription() 或子对象具有的任何功能
