我想使用視圖中的按鈕將一個表（形式）中的行的值復制到另一個表（發(fā)票）中的行。但出現(xiàn)錯誤：方法 Illuminate\Database\Eloquent\Collection::create 不存在。在線的：'grosstotal' => $proform->grosstotal,這是我的控制器方法：public function duplicate(Request $request){ $proform = $this->proform->findOrFail($request->duplicate);$invoice = Invoice::all();//something like this$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]);}
