Hi All,
I am a cakephp beginner and I need your support regarding an issue
with updating HABTM models.
I noticed a weird behavior that cakephp is doing which is deleting all
old rows and inserting new ones whenever and HABTM model is edited. I
read in the cookbook that this how it is, and I read that there is a
'unique' attribute which is considered as a flag for this 'delete old
- insert new' process.
Is there anyway one can overcome this? The problem is that the id of
the join table itself, is used as a foreign key in other tables that's
why it cannot be deleted. I was thinking of saving the rows at the
beginning, removing the association on the fly and then inserting the
data (the old ones which weren't deselected and the new selected ones)
manually.
Any ideas?
Thanks,
Rami.
