[EMF] [Teneo] [Hibernate] Reference on NON Primary Key [message #815899]

Thu, 08 March 2012 02:12

Hallo,

i have 2 EClasses:

Class Person
- ID = PrimaryKey
- Name
- otherUniqueID

Class Adress
- ID = PrimaryKey
- person = Refrence to Person.otherUniqueID
- street
- city

I use a Ecore-Model with Teneo and Hibernate. The problem is, that i dont know the annotation for the person-reference in class "Adress". Does anybody know, how to do that??

Many thanks
Nils

Hi Nils,
Can you try this one:
@JoinColumn(referencedColumnName="otherUniqueID")
in the Address.person ereference
the referencedColumnName can be the efeature name on the other side.

Hi Martin,

thank you very much for your quick reply. I have defined an annotation on the specified reference (Address.person):

@JoinColumn(name = "key", referencedColumnName="otherUniqueID")

Unfortunately it doesnt work. The first parameter (name = "key") is beeing executed but the second parameter (referencedColumnName="otherUniqueID") is beeing ignored without any error message. Adress.person is still referenced with Person.id. Any idea?

Thank you Smile

Nils

Hi Nils,
Did you regenerate the java code? This is needed when adding annotations to the model, as EMF generates java code which
builds the model at runtime.

Hi Martin,

yes, i regenerated the model. It seems that teneo ignores the 2nd part of the annotation.

Greetings

Can you try putting it in an enclosing JoinColumns annotation:
@JoinColumns({@JoinColumn(name = "key", referencedColumnName="otherUniqueID")})

This format I have in several testcases.

The database-field with the specified name (for example "key111") is created, but the reference is still on the primary key.

greetings,

Okay, how does the generated hbm look like (you can check it through dataStore.getMappingXML()).
