doctrine-orm - Doctrine2 - One-to-many Association with parent name

Question

Is it possible to create a parent name field into one-to-many association in Doctrine2.

For example, we have a Meeting. This meeting can be associated with Contacts or with Accounts.

Example of data:

     meeting_name         | parent_name | parent_id
------------------------------------------------------
Meeting with a friend     | Contacts    | <contact_id>
Meeting with the customer | Accounts    | <account_id>

Is possible to implement it in Doctrine2?

Thanks

Answer 1

是的，当然。但是，我会使用父类的 FQDN 而不是其名称。此外，您可以创建一个自定义 hydrator。

或者，您可以只创建两个多对多关系，一个用于 meeting_customer_attendees，一个用于 meeting_friend_attendees。
