试图了解如何制作 UpdateOrCreate

Question

I have a model with the following code:

    public static function insertSent($itemId, $currentPackId)
    {
        $itemHistory = new ItemHistory([
            'item_id' => $itemId,
            'pack_id' => $currentPackId,
            'status' => self::SENT,
            'returned_by' => Auth::id()
        ]);

        $itemHistory->save();
    }

    public static function insertReturned($itemId, $currentPackId)
    {
        $itemHistory = new ItemHistory([
            'item_id' => $itemId,
            'pack_id' => $currentPackId,
            'status' => self::RETURNED,
            'returned_by' => Auth::id()
        ]);

        $itemHistory->save();
    }

I just added the insertSent and I want to change the insertReturned to a function where it updates a record if it exists or creates it so UpdateOrCreate.

You can adjust your method to use updateOrCreate pretty easily:

public static function insertReturned($itemId, $currentPackId)
{
    ItemHistory::updateOrCreate([
        'item_id' => $itemId,
        'pack_id' => $currentPackId,
    ], [
        'status' => self::RETURNED,
        'returned_by' => Auth::id(),
    ]);        
}

The first array is what you are looking for. If a record is found fill it with the second array and save. If no record is found merge the first and second array and create the new record.
