ARDataBinder cannot know that the schedules are not in UI and will assume
the user left them blank. Tell the binder by using the Exclude-property:
[ARDataBind("task",..., Exclude="Schedules")]Task task-Markus 2009/7/3 Cesar Sanz <[email protected]> > >Delete means that the ids are nulled when the schedule is removed from > the task or the task is deleted > So, if task is deleted, my schedules will still continue in the database > but with the foreign key (task_id) set to NULL? > Or will be deleted physically from database? > > >What you mean is perhaps AllDeleteOrphan, which also deletes orphaned > schedules. > What I want is, Do not update my schedules when task is updated. > > This project is been developed using monorail, I update a task from a > interface created for this purpose. > When I make the post I can see that task.Schedules = null, because I do > not utilize schedules in this UI. > > What can I do to solve this issue? > > ----- Original Message ----- > *From:* Markus Zywitza <[email protected]> > *To:* [email protected] > *Sent:* Friday, July 03, 2009 9:38 AM > *Subject:* Re: AR cascading is Wrong (urgent!) > > Delete means that the ids are nulled when the schedule is removed from the > task or the task is deleted.
