LaravelBackpack 5.5：MassAssignmentException将[date_times]添加到fillable属性，以允许在[App \ Models \ Fbpage]上进行批量分配

Question

我创建了laravelbackpack fbtracking项目。当我添加数据库迁移数据时，出现错误为“ LaravelBackpack 5.5：MassAssignmentException将[date_times]添加到fillable属性，以允许在[App \ Models \ Fbpage]上进行批量分配。”

这是我的Laravel代码 01-数据库表迁移

enter code here
public function up()
{
    Schema::create('fbpages', function (Blueprint $table) {
        $table->increments('id');
        $table->date('date_times');
        $table->string('fb_names');
        $table->double('fb_likes');
        $table->timestamps();
    });
}

02-模型“ Fbpage”

enter code here

Fbpage类扩展模型 {     使用CrudTrait;

protected $table = 'fbpages';
// protected $primaryKey = 'id';
 public $timestamps = false;
// protected $guarded = ['id'];
protected $fillable = [];
// protected $hidden = [];
 protected $dates = ['created_at', 'updated_at', 'deleted_at', 'date_times'];}
