Hello
I normally bottom-post but the mailing list cut it off.
Case 1, I am adding to both parent and child. The the self.Form.Save()
should save the parent, then do a saveall on the children if I
understand correctly. If I get this working then case 2 would be used to
add further rows. ie. like a VFP grid which always has a hot new row
available on the grid.
Case 2 - I have a parent record that is on the Form through
self.Form.requery(), go through record with next, prior, what ever.
do the self.Form.new("public.cmpd_ingredients") to add a new row to the
child or the grid.
Case 3 - Data added to child database externally. Then I can change data
in those records and issue the self.Form.save(). However if I add a new
child it gives the error.
Both cases fail when trying to save the children.
Case 1 the parent is saved then the error.
How else can I add a new record to the child Biz object?
Isn't this a normal 1 to many form, like an invoice or purchase order.
How are others doing this and not running into the problem?
This is a common type of situation that I program for.
Do you have a solution for a 1 to many data entry form.
The screencasts and the tutorial I found do a great job of displaying 1
to many after the fact but I haven't found code that helps when adding
the data the first time.
Thank you
Paul
