As per save Cursor Method documentation
This method saves data to the database. The Cursor class automatically determines if the record should be updated or inserted as a new entry, based on the return value of dry.
In case a new record is created how do I retrieve its auto-increment primary key id (this is how my tables are defined) ?
I'm used to look for the mapper instance propery _id but this is undocumented (afaik).
I suppose I can set up an afterinsert() event handler but I was looking for a more straightforward approach. Is there one?
It is very easy and straighforward:
after a save() on a "dry" record (a new record has been created) autoincrement primary keys are updated on the mapper object, so in my case:
$mapper->save();
$id = $mapper->id;
