Question

这是我的控制器，但我可以下载excel。控制器和模型的位置都是相同的，我已经检查了它但仍然有一个错误，它说“Class”App \ Item“Not Found”。

namespace Vanguard\Http\Controllers\Web;
use Input;
use App\Item;
use DB;
use Excel;
use Illuminate\Http\Request;
use Vanguard\Http\Controllers\Controller;
use Cache;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;

class MaatwebsiteDemoController extends Controller
{
    public function importExport()
    {
        return view('importExport');
    }
    public function downloadExcel()
    {
        $data = Item::get()->toArray();
        return Excel::create('itsolutionstuff_example', function($excel) use ($data) {
            $excel->sheet('mySheet', function($sheet) use ($data)
            {
                $sheet->fromArray($data);
            });
        })->download($type);
    }
    public function importExcel()
    {
        if(Input::hasFile('import_file')){
            $path = Input::file('import_file')->getRealPath();
            $data = Excel::load($path, function($reader){
            })->get();
            if(!empty($insert)){
                foreach ($data as $key => $value) {
                    $insert[] = ['title' => $value->title, 'description' => $value->description];
                }
            if(!empty($insert)){
                DB::table('items')->insert($insert);
                dd('Insert Record succesfully');
            }
            }
        }
        return back();
    }
}

然后这就是我的模型。

<?php

namespace Vanguard\App;

use Illuminate\Database\Eloquent\Model;

class Item extends Model
{
    public $fillable = ['title','description'];
}

Answer 1

您模型的FQCN为Vanguard\App\Item，而不是App\Item。

Answer 2

您正在致电App\Item课程，而您的课程为Vanguard\Item 的 1。使用Vanguard\Item模型

use Input;
// use App\Item; // REMOVE that line
use Vanguard\Item; // ADD this line
use DB;
use Excel;
use Illuminate\Http\Request;
use Vanguard\Http\Controllers\Controller;
use Cache;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;

class MaatwebsiteDemoController extends Controller
{
    ...
}

<强> 2。修改模型命名空间。

namespace Vanguard;

use Illuminate\Database\Eloquent\Model;

class Item extends Model
{
    public $fillable = ['title','description'];
}

第3。并运行composer dump-autoload

在Laravel中找不到类“模型名称”
