Hello in addition to the topic above,
i have the same problem and this suggestion sounds nice for me!
I'd like to check if the ID of the record to be deleted exists in a
foreign key in some other table (i have to check all associated
tables) or record.
Could someone help me to build an example for this?
[code of my updated delete fuction in appController]
function delete($id)
{
# check (with find('count') or something else) if the
ID of the record to be deleted exists in a foreign key in some other
table #
if ( # the record is "not used" # )
{
$this->{$this->modelClass}->del($id);
$this->Session->setFlash('delete (id: '.$id.') works!');
}
else
{
$this->Session->setFlash('Could not be deleted
because of ...');
}
$this->redirect(array ('action' => 'index'));
}
[/code]
Could someone help me please? Thanks!
