jpa new entity extension: alternate names for @Id and @Version properties

[jjfraney]

Forge 3.1.0:

What paths for extension are available to get forge to generate different names for @Id and @Version properties?  In our development shop, we use a surrogate key for @Id and use the name 'sid' instead of 'id' for the property.  We also use 'rowVersion' not 'version' for the @Version property.

I'd also like to identify a property as the natural id of the entity.  This is a different kind of extension than simply using an alternate name.

Looks like the jpa new entity command has these hardwired to 'id' and 'version' (See: org.jboss.forge.addon.javaee.jpa.PersistenceOperationsImpl.createJavaEntityClass(String, String, GenerationType, String) )

I think I have to create my own ui command in my own addon.  If so,

1) Can I rebind 'jpa-new-entity' to my new ui command object?

2) What extension points are there in the current jpa-new-entity command that I may customize it?  I think none, and I'll have to copy out the jpa-new-entity command into my own addon project, then modify it.

Thanks,

John

Hi John,

Right now there are no extension points for the jpa-new-entity command, so unfortunately you'll have to create your own UI command in your own addon and with a different name.

You can do the same as JPA: New Entity does now, and change the field name returned from PersistenceOperations.newEntity using the Roaster API.

It would be nice if you could open a JIRA in Forge - JBoss Issue Tracker so we can investigate a way to support rebinding command names.

Thank you very much and sorry for the trouble.

Here is another hint: You could implement a CommandExecutionListener and in the postCommandExecuted method, check if the JPANewEntityCommand was executed and apply the necessary changes.

Let me know if you need any help

Thanks for the quick response.
