Re: Checking a value on a DataObject and modifying it before commit if required

My guess would be “no”. I suggest you don’t model the relationships until the foreign systems are fixed or removed. In the meanwhile, I would implement methods as the relationships, that would know if there’s a fictitious value or not and return NULL for the relationship. When the other

Re: "Phantom" object being created - how and why?

So, I don’t know if Cayenne does this, but WebObjects used to create phantom objects too… The reason it did it was because there was a mandatory to-one relationship in the model, where the primary key of the source of the relationship was also the primary key of the related object. This is

the same object is modified multiple times. It is easy to redefine this behavior by overriding "DataObject.writeProperty(..)" and friends in your own superclass. Andrus > On Apr 27, 2018, at 6:31 PM, Ken Anderson <ken.ander...@amphorainc.com> wrote: > &

Check dirty before write?

It *seems* like Cayenne (4.0) doesn’t check to see if a property being set is different from the prior value before making the object dirty. Is that a correct observation? If so, is there a reason it doesn’t? Thanks, Ken Confidentiality Notice: This e-mail and accompanying documents contain

ing errors could be handled in the save with some custom logic and a retry. Or if this isn't a super long process you can use a database transaction to allow saving multiple times without actually having that data be visible outside of the transaction. On Wed, Mar 28, 2018 at 6:56

Staged saves pattern ?

All, We have a process that reads in a file and, for each line, creates or edits objects in the object graph. We only want to commit to the database once at the end. We have a finite set of lines, so memory is not an issue. We need to save only once because saving will actually fire
