OnPrePersist not working

[Bruno René Santos <br...@holos.pt>]

Hello All,

I have created a pre-persist callback to set a property from my pojo. But when I commit changes the callback is not executed... Any ideas? For instants, the post-add callback works great.

Thank you

Re: Raw delete

[Michael Gentry <mg...@masslight.net>]

I've done this in the past:

    QueryChain  chain = new QueryChain();

    // Add raw SQL templates to the chain.
    chain.addQuery(new SQLTemplate(Customer.class, "DELETE FROM Customers"));
    chain.addQuery(new SQLTemplate(Item.class, "DELETE FROM Items"));
    chain.addQuery(new SQLTemplate(LineItem.class, "DELETE FROM LineItems"));
    chain.addQuery(new SQLTemplate(Order.class, "DELETE FROM Orders"));

    // Execute all of the SQL statements.
    dataContext.performNonSelectingQuery(chain);

Keep in mind that isn't a good thing to do if you are concerned about
your in-memory object graphs (DataContexts/etc) suddenly becoming
out-of-sync.  Also, if you don't need to do multiple deletes, you
don't need the query chain part.

Raw delete

Hello all,

Whats the better way to do a regular delete from in raw sql? I tried a raw
sql named query on the modeler but i get a Null PK error, maybe because no
data rows are returned?

Thank you

Maybe a good idea actually. Care to open a Jira? We'll think about it.

Hi Andrus,

I have just found out the problem. I wa trying to affect a cayenne-mandatory
table field with a calculated value during pre-persist. I think the problem is
that Cayenne mandatory validation is executed before the prepersist, not letting
me affect the field, which starts as null. Do you think validating after
pre-persist could lead to problems? I think it would help pre-persist to be more
useful, allowing us to calculate mandatory fields.

I made it work by removing the Mandatory check on Cayenne Modeler.

Bruno Santos

Odd. Should be working. Do you actually see INSERT statement in the logs, but no
callback before that?
