阅读更多关于 Deep clone Doctrine entity with related entities

I have created an entity A with OneToMany relation to B , which have relation OneToMany to C . I have to clone this A entity and set it in database with new id. Also all deep relations should be cloned with new ids too. What have I tried is to set A id to null : $A = clone $A_original; $A->setId(null); $em->persist($A); It creates new record in A table, but does not in B and C .

Because if you keep the id in the related

问题 I have a preUpdate listener in my app. When it is fired I want it to create some additional records. A simplified example of the basic functionality is below.

阅读更多关于 JMSSerializerBundle. no control over third party meta data

问题 I have two entities I wish to serialize with the JMSSerializerBundle. The Music Entity has a mapping-file with exclusion_policy: NONE . The Music entity has a field of the entity User from FOSUserBundle . The User entity has a mapping-file with exclusion_policy: ALL with a few fields set to expose: true , so they will be serialized. The problem is, the User field gets fully serialized. It does not matter if I change the mapping-file of the User entity. This is how it looks: #My/Bundle

阅读更多关于 How to get list of all routes of a controller in Symfony2?

问题 I have a controller which implements all routes/URL(s) . I had the idea to offer a generic index over all help-pages.
