【问题描述】：

我想使用视图中的按钮将值从一个表（表格）复制到另一个表（发票）中的行。但出现错误：方法 Illuminate\Database\Eloquent\Collection::create 不存在。 在线：'grosstotal' => $proform->grosstotal,

这是我的控制器方法：

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]);

这是我的视图，带有重复按钮：

这是我的路线

<?php

use Illuminate\Support\Facades\Route;
Route::get('/', function()
return view('welcome');
);

Route::get('home');
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Auth::routes();

Route::get('/home', 'HomeController@index')->name('home');

Route::group(['middleware' => ['auth']], function () 
Route::get('/search', 'UserController@search');
Route::get('/search2', 'ProductController@search2');
Route::get('/search3', 'ProformController@search3');
Route::get('/search4', 'InvoiceController@search4');

Route::post('/duplicate', 'ProformController@duplicate')->name('proforms.duplicate');
Route::get('data', 'UserController@index');
Route::get('posts', 'PostController@index');
Route::get('/prodview', 'TestController@prodfunct');

Route::resource('roles', 'RoleController');
Route::resource('users', 'UserController');
Route::resource('permissions', 'PermissionController');
Route::resource('products', 'ProductController');
Route::resource('invoices', 'InvoiceController');

Route::resource('category', 'CategoryController');
Route::resource('invoices', 'InvoiceController');
Route::resource('proforms', 'ProformController');
);

复制就是为了它。

【参考方案1】：

在你的代码中

// all() gets you the collection of the Invoice Model instances of all the entries of invoice in the database.

$invoice = Invoice::all();

$duplicated = $invoice->create([..

在哪里 $invoice 是发票模型实例的集合。您不能在集合上应用create 方法。

您需要使用 Invoice 的模型来创建。

所以把上面的创建代码改成

$duplicated = Invoice::create([..
