My DB is postgres, how can I contribute/replace de PostgresPkGenerator with my
own implementation to genera UUID's as PK's:
public class PcExpressPosUUIDPkGenerator extends PostgresPkGenerator {
public PcExpressPosUUIDPkGenerator(@Inject PostgresAdapter adapter) {
super(adapter);
}
I opened my project with Cayenne Modeler, and accept all.
It fails to migrate correctly inter-datamap references... referecens in same
datamap are ok.
The skeleton for the inter-datamap relationships are shown with empty targets
and details.
Thanks for your great tool.

We have a task for that [1], but no estimate though.

This is to be get the "comment" of the mapping node of attributes to generate

I would like to add metadata and use it at runtime to generate automatic UI to
edit entities... metadata like column title, label, java validation tags, etc.

The purpose is to use db stored procedures to do the post-processing of my
object graph, something like (seudo-code);
start cayenne transaction
cayenne commitChanges();
call stored procedure/function to post-process (heavy process).
commit cayenne transaction
I would be nice that if st
runtime.performInTransaction(() -> {
// ... do some changes
context.commitChanges();
// ... do more changes
context.commitChanges();
return true;
}); Previous code is an example on "Guide to 4.0 Features".
My questions are:
- What is then persis
I am using 4.0.M5.
The next code used to work in a previous version, but now PCADataDomainProvider
is never called to create my custom DataDomain:
public class ServerModuleWithPostCommitActions implements
org.apache.cayenne.di.Module {
@Override
public void configure(Binder binder) {

Is there any way to call a stored procedure as part of commitChanges ?
I would like to call a stored procedure after flushing my persistent objects
but before the real db commit, for instance, to make some process on the db as
part of committing my objects, but transactionally.

Looks like a bug to me too. Will investigate and file a bug (and
ideally make a fix) if required.

I found that If you map a procedure and you pass a wrong parameter name on
ProcedureCall, Cayenne does not throw an exception, it just pass null to db for
the missing parameters.
This could be a bug or enhancement, but I do not know where to put this
comment, hope someone knows.

The problem is that your commit failed. You have to rollback the context if
you want to keep using it.

I have a dataobjet graph with some changes, and a db stored procedure that
should run after this changes are in the db, but must run in the same
transaction because it make some more changes to other data, this changes can
fail so I want the commitChanges fail if the stored procedure fails.
