Laravel 6关系与数据库中不同的表名一对多

Question

我在关系方面遇到了很大的问题，不幸的是，我决定在数据库中使用不同名称的模型和表，因此laravel无法正确匹配它们。我已将protected $table变量添加到FuseCollector模型中，并将表名和列名添加为用户模型中hasMany()方法中的第二和第三属性，但仍然无法使用。我正在寻找解决方案两天，然后将头发拔出头来。请帮助！

我的数据库表：

fusecollector_projects: id (key), user_id (foreign key), notes, created_at, updated_at
users: id (key), name, email, email_verified_at, password, remember_token, created_at, updated_at

模型FuseCollector（App \ FuseCollector.php）

namespace App\FuseCollector;

use Illuminate\Database\Eloquent\Model;

class Project extends Model
{
    protected $table = 'fusecollector_projects';
    protected $fillable = [
        'name', 'notes'
    ];
     public function user()
    {
        return $this->belongsTo('App\User');
    }
}

模型用户（App \ User.php）

<?php

namespace App;

use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];
    public function fuseCollectorProjects()
    {
        return $this->hasMany('App\FuseCollector\Project', 'fusecollector_projects', 'user_id');
    }
}

控制器项目（App \ Http \ Controllers \ FuseController \ Project.php）

<?php

namespace App\Http\Controllers\FuseCollector;

use Request;
use App\Http\Requests\CreateFCProjectRequest;
use App\FuseCollector\Project;
use Auth;
use Session;
use App\Http\Controllers\Controller;
//use App\Http\Requests;

class ProjectController extends Controller
{
    public function index()
    {
        return view('fusecollector.project.index');
    }
    public function create()
    {
        return view('fusecollector.project.create');
    }
    public function store(CreateFCProjectRequest $request) // zapisywanie projektu do bazy
    {
        $project = new Project($request->all());
        Auth::user()->fuseCollectorProjects()->save($project);
        Session::flash('video_saved', 'Film został zapisany');
        return redirect('fusecollector.project.index');
    }
}

[当我尝试从我的简单创建表单（仅'name'和'notes'字段）使用create（）方法时，我收到错误消息：

Symfony\Component\Debug\Exception\FatalThrowableError
Call to a member function fuseCollectorProjects() on null
App\Http\Controllers\FuseCollector\ProjectController::store:26

第26行是：

Auth::user()->fuseCollectorProjects()->save($project);

我知道关系存在问题，所以我尝试检查php artisan tinker中的关系：

>>> $p = new App\FuseCollector\Project
=> App\FuseCollector\Project {#3061}
>>> $p->first()
=> App\FuseCollector\Project {#3068
     id: 1,
     name: "Projekt",
     user_id: 1,
     notes: "aaa",
     created_at: "2020-01-04 23:42:12",
     updated_at: "2020-01-04 23:42:12",
   }
>>> $u = new App\User
=> App\User {#3055}
>>> $u->first()
=> App\User {#3072
     id: 1,
     name: "ForgottenLord",
     email: "[email protected]",
     email_verified_at: null,
     created_at: "2020-01-04 01:00:49",
     updated_at: "2020-01-04 01:00:49",
   }
>>> $p->user()
=> Illuminate\Database\Eloquent\Relations\BelongsTo {#3063}
>>> $u->fuseCollectorProjects()
=> Illuminate\Database\Eloquent\Relations\HasMany {#3070}

它表明没有关系，我不知道为什么！
