Laravel 關系為空，定義錯誤？

Question

稍作休息后，我想繼續我自己的項目。 但是，我現在坐在這里已經兩個小時了，不知道我做錯了什么或者我的錯誤在哪里。

所以，我有可以創建產品、評論和喜歡評論的用戶。 但是，當我想檢索用戶發布的所有產品或評論或用戶喜歡的所有評論時，我總是得到沒有內容的 hasMany 關系（我在儀表板刀片中調用了$user->products() ，由UserController ）：

    Illuminate\Database\Eloquent\Relations\HasMany {#662 ▼
      #foreignKey: "products.user_id"
      #localKey: "id"
      #query: Illuminate\Database\Eloquent\Builder {#656 ▶}
      #parent: App\User {#654 ▶}
      #related: App\Product {#663 ▼
        #with: array:1 [▶]
        #connection: "mysql"
        #table: null
        #primaryKey: "id"
        #keyType: "int"
        +incrementing: true
        #withCount: []
        #perPage: 15
        +exists: false
        +wasRecentlyCreated: false
        #attributes: []
        #original: []
        #changes: []
        #casts: []
        #dates: []
        #dateFormat: null
        #appends: []
        #dispatchesEvents: []
        #observables: []
        #relations: []
        #touches: []
        +timestamps: true
        #hidden: []
        #visible: []
        #fillable: []
        #guarded: array:1 [▶]
      }
}

誰能告訴我哪里出錯了？

用戶 model：

class User extends Authenticatable
{
    use Notifiable;
    use HasRoles;
    use HasSettingsField;

    /**
     * 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',
    ];

    /**
     * Get the products record associated with the user.
     */
    public function products()
    {
        return $this->hasMany('App\Product');
    }

    /**
     * Get the comments record associated with the user.
     */
    public function comments()
    {
        return $this->hasMany('App\Comment');
    }

    /**
     * Get the comment likes record associated with the user.
     */
    public function commentlikes()
    {
        return $this->hasMany('App\CommentLike');
    }
}

產品 model：

    class Product extends Model
    {

    /**
     * The relationships that should always be loaded.
     *
     * @var array
     */
    protected $with = ['comments'];

    /**
     * Get the user that owns the product.
     */
    public function user()
    {
        return $this->belongsTo('App\User');
    }
}

評論 model：

/**
 * Display the specified resource.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function show(User $user)
{
    return view('pages.userDashboard')->with([
        'user' => $user
    ]);
}

Answer 1

我認為像財產一樣訪問它就可以了。 不要像方法一樣調用它，如果你這樣做，它將調用方法。

$user->products;

$user->comments;
