issue an invoice按钮用于将porform表中的一行发送到invoices。大多数列都有相同的名称。有一个问题，因为一半的价值没有转移。我把$proform打给dd（$proform），就在那里了。我做错什么了？在这里你可以看到我如何检查grossunit和值​​显示得很好，但不会发送到第二个表。这是我控制器的一部分。

public function duplicate(Request $request)

{

$proform = $this->proform->findOrFail($request->duplicate);

$invoice = Invoice::all();

dd($proform->grossunit);

//something like this

$duplicated = Invoice::create([

'invoicenumber' => $proform->proformnumber,

'invoicedate' => $proform->proformdate,

'selldate' => $proform->selldate,

'user_id' => $proform->user_id,

'form_id' => $proform->form_id,

'currency_id' => $proform->currency_id,

'paymentmethod' => $proform->paymentmethod,

'paymentdate' => $proform->paymentdate,

'status' => $proform->status,

'comments' => $proform->comments,

'city' => $proform->city,

'autonumber' => $proform->autonumber,

'automonth' => $proform->automonth,

'autoyear' => $proform->autoyear,

'name' => $proform->name,

'PKWIU' => $proform->PKWIU,

'quantity' => $proform->quantity,

'unit' => $proform->unit,

'netunit' => $proform->netunit,

'nettotal' => $proform->nettotal,

'VATrate' => $proform->VATrate,

'grossunit' => $proform->grossunit,

'grosstotal' => $proform->grosstotal,

]);

return redirect()->route('invoices.show', ['invoice' => $duplicated]);

}

这是发票型号：
