Let's say I have entity
$e. Is there any generic way to store it as another row, which would have the same entity data but another primary key?
Why I need this: I'm implementing some sort of Temporal Database schema and instead of updating the row I just need to create another one.
Try cloning and add the following method to your entity
You may need to detach the entity before persisting it. I don't have my dev machine handy to test this right now.
Just tried using a simple SQLite demo. You shouldn't need to do anything. The following worked for me without adding a
__clone()method or doing anything else out of the ordinary
Once flushed, the
$newentity had a new ID and was saved as a new row in the DB.
I would still null the ID property via the
__clone()method as it makes sense from a pure model view.
Digging into the Doctrine code, this is because the generated proxy classes implement
__clone()with this important line
