“Global variable” in Symfony2

Question

I'm new to Symfony. I have an action that takes from the database a random object A and display it with Twig. It also shows a form. When the form is submit, it is "relaunching" the action and show another random object A.

How can I do to save my object A (which is a entity)? I thought about a global variable but I've read this is not very good)

I think it's all about the "symfony" logic that I don't have yet :)

PS : I'm french, sorry if my english is a bit bad :)

Thank you in advance,

Julien

如果您想在表单发送后显示同一对象，则必须添加到存储对象ID的表单隐藏字段中（可能如果您正在使用数据库，它已经具有主键，并且您可以通过$ entity-> getId（）来获取它）
