[squeak-dev] SandstoneDb question

Hi,
I'm using SandstoneDb for a project... and I have this (one-to-many) scenario:

a) Product as Parts
b) a Part can be owner by a Product, or can be orphan

so, I have two roots: Product and Part

well, by design, Sandstone does not allow me to make a recursive
commit, and I have to make that commit by hand, something like this:

self product partsDo: [ :each |
        each isNew ifTrue: [ each commit ].
self product commit.

but... I need this behaivor in many parts of my environment, so I
rewrited #commit, this way:

Product>>commit
        self partsDo: [ :each |
                each isNew ifTrue: [ each commit ].
        super commit.

My question is: is this design right? Is there another -cleaner- way to
do this?

Thanks in advance,
Esteban

pd: maybe #commitWithRelations is better than overwrite commit?

I'd say that's not a good approach.  The problem is you're adding new Parts
to a Product, if Part can stand alone, then save them prior to creating the
relationship.  Relationships are between committed objects.  You're trying
to treat the Part as an aggreagte of Product when it clearly isn't if a Part
can exist without a Product.

No, you'll need to save your image, SandstoneDb just saves simple objects.
