Re: [SimpleORM] Making detaching the default behaviour

Hi Anthony,

in my app, I tend to always detach records, to display and update them
in the presentation layer. I also detach them to handle business rules
in the business layer. Cases where I read / udpate / commit from within
a single Simpleorm transaction are ... well, I don't have such case
until now :) And I have been beaten by the destroy behaviour in methods
that were only querying data, where I would detach the main record, but
not the one implicitely attached to the transaction because they were
references.

But I understand your argument. Maybe I could add a method to
SConnection to detach all records, leaving the default behaviour to
destroying, but giving one stop choice for those of the detaching kind
like me.

Don't know if somebody else has an opinion on the subject ?

Franck

I like your idea of a detach all records method. It also avoids the issues of partial detachment, where children are detached but not parents. Anthony ... ...

Ok, so I went on and added a SConnection.detachDataSet() static method to SConnection. Beware, SConnection.commit(), SConnection.detachAndClose(), ... still ...
