In 3.0 you can start with an abstract ObjEntity instead of a
superclass outside Cayenne. You will still have to create those
columns in the DbEntity definitions. Also this feature is rather new,
so there may be some snags in runtime.
So I guess the safest path is what I described in my original message.
Also if you are on 3.0M5, you can use copy/paste in the Modeler to
propagate common DbAttributes. Not ideal of course, but should
eliminate some typing and clicking.

Hi
thx for answer ,glad that is possible but is till have one question.
if i start desingning the database i should add this commom fileds
manually
to all tables ?
or is possible to start with objects and then generate tables ?
cause if i start with objects and for each object i create i just
specify
that it extedns a class that has those common fields then is super
ok .

Hi there,
you can use a common superclass that extends CayenneDataObject. Enter
it for the DataMap under "Custom Superclass" and then click
"Update...".
Optionally you may declare getters and setters as abstract in this
superclass. Whether you do that or not, Cayenne will generate correct
access code in subclasses.

i would like to do the folowing :
each table that i will have into my database must have :
id
create_date
create_user_id
write_date
write_user_id
Normally i though to subclass each of my data model classes to a
class
that has these fields.
How this can be done using cayenne ?
Thx
