Import Laravel Excel to two models with relationship

I am trying to import Excel file [using Laravel Excel library] into two different models that has relationship between them.

I tried the below solution by returning two models import, and the second one is getting the inserted ID from the first model => Item::where('barcode', $row['barcode'])->pluck('id')->first(), but always getting NULL item_id in the second model.

<?php

    public function uniqueBy()
    {
        return 'barcode';
    }
}

On the controller:

Excel::import(new CodingImport, $request->file);

Any idea how to do this?

Laravel Excel import don't commit or do batch insert until it is complete. If you want to use relation you should use OnEachRow.

Here is the example

public function onRow(Row $row)
{
    $row = $row->toArray();
    Cprices1()::create([
            'item_id'    => Item::where('barcode', $row['barcode'])->pluck('id')->first(),
            'msrp'       => $row['msrp'],
            'rtp'        => $row['rtp'],
            'item_cost'  => $row['cost']
        ]);
}

    }

    public function uniqueBy()

Just note:

When using OnEachRow you cannot use batch inserts, as the model is already persisted in the onRow method.
