php - Good practices with symfony 2 : Make a facebook like friend request

Question

I am working on a Web App using Symfony2 and I'd like to make a facebook friend request like system.

User "A" ask permission to user "B" to do something. User "B" should see a notification asking confirmation.

I asked my self what is a good way to do that. I though about creating an entity "request" whit User "A" (Object), User "B" (user_id field, using ManyToOne relation in Doctrine), Type (string) and Date field.

However, using object type will serialize the User "A". It seems a little heavy. And Using User "A" id instead of all object is not really Object Programming friendly.

Answer 1

你绝对是在正确的轨道上。这就是你应该在 Symfony2 中使用 Doctrine2 的方式。

创建一个Request包含以下字段的实体：

• id
• sender（与用户实体的多对一关系）
• receiver（也是与用户实体的多对一关系）
• date
• 无论您使用更多字段

或者，根据您的目标，您可以直接向FriendshiporAction实体添加一行并处理一个字段confirmed或confirmed_time分别为 NULL 的字段，直到友谊/动作得到确认或完成。
