Laravel 5.6 Reflectionexception - 类 App\Providers\App\Campaign 不存在

Question

这件事让我很难过。

我收到此错误/反射异常 -> Class App\Providers\App\Campaign 不存在

Campaign 是为应用创建的类。

奇怪的是，这个错误只在我使用“显示”资源路由时出现。当我使用“索引”路线列出它时。我没有收到任何错误。

课程如下：

---

namespace App;

use Illuminate\Database\Eloquent\Model;

class Campaign extends Model
{
protected $table='campaigns';
protected $primaryKey = 'campaignID';
protected $fillable = [
    'campaignID',
    'campaignName',
    'shortDescription',
    'longDescription',
];

public function company(){
    return $this->belongsTo('App\Company','companyID','companyID');
}

    public function person(){
    return $this->belongsTo('App\Person','campaignID','campaignID');
    }
}

---

这是控制器的“显示”功能

---

public function show(Campaign $campaign)
{
    $campaign = Campaign::find($campaign->campaignID);
    return view('campaigns.show', ['campaign'=>$campaign]);
}

编辑 - 这是整个控制器

<?php

namespace App\Http\Controllers;

use App\Campaign;
use App\User;
use App\Company;
use App\Lead;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Storage;

class CampaignsController extends Controller
{
    /**
    * Display a listing of the resource.
    *
    * @return \Illuminate\Http\Response
    */
    public function index()
    {
        $campaigns=Campaign::get();
        return view('campaigns.index', ['campaigns'=> $campaigns]);
    }

/**
 * Show the form for creating a new resource.
 *
 * @return \Illuminate\Http\Response
 */
public function create()
{
        return view('campaigns.create');
}

/**
 * Store a newly created resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function store(Request $request)
    {
        $coID = Auth::user()->companyID;
        $uID = Auth::user()->id;


        $campaign = Campaign::create([
            'campaignName' => $request->input('campaignName'),
            'shortDescription' => $request->input('shortDescription'),
            'longDescription' => $request->input('longDescription'),
        ]);


        if($campaign){
            $campaigns=Campaign::where('companyID',Auth::User()->companyID)->get();
            return view('campaigns.index', ['campaigns'=> $campaigns])
                ->with('success' , 'Campaign created successfully');
        }
        return back()->withInput()->with('errors', 'Error creating new campaign');
    }    

/**
 * Display the specified resource.
 *
 * @param  \App\Campaign  $campaign
 * @return \Illuminate\Http\Response
 */

public function show(Campaign $campaign)
{
    $campaign = Campaign::find($campaign->campaignID);
    return view('campaigns.show', ['campaign'=>$campaign]);
}
/**
 * Show the form for editing the specified resource.
 *
 * @param  \App\Campaign  $campaign
 * @return \Illuminate\Http\Response
 */
public function edit(Campaign $campaign)
{
    $campaign = Campaign::find($campaign->campaignID)->toSQL();
    dd($campaign);
    return view('campaigns.edit', ['campaign'=>$campaign]);
}

/**
 * Update the specified resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  \App\Campaign  $campaign
 * @return \Illuminate\Http\Response
 */
public function update(Request $request, Campaign $campaign)
{
    //
}

/**
 * Remove the specified resource from storage.
 *
 * @param  \App\Campaign  $campaign
 * @return \Illuminate\Http\Response
 */
public function destroy(Campaign $campaign)
{
    //
}

public function listcompanycampaigns()
{
    $campaigns=Campaign::where('companyID',Auth::User()->companyID)->get();
    return view('campaigns.index', ['campaigns'=> $campaigns]);
}

public function listambassadorcampaigns()
{
    $campaigns = Campaign::get();
    return view('campaigns.ambassadorindex', ['campaigns'=> $campaigns]);
}

}

我已经清除缓存和“composer dump-autoload”无济于事。

感谢你们提供的任何帮助。

您的路线是什么样的？你在使用路由模型绑定吗？

如果你是，那么你应该先了解它是如何工作的：

https://laravel.com/docs/5.6/routing#route-model-binding

否则，请删除 show 方法中的类型提示，并在 find 方法中使用实际整数查找模型。
