Master - Detail example

Does anyone have a Master/Detail symfony2 example? I was trying to add multiple products to a category, all from on开发者_开发问答e form, but I´m not abble to get parent id in the controller to persist data.

Have a look there: http://tutorial.symblog.co.uk/docs/extending-the-model-blog-comments.html#the-controller

I think that is what you need.
