admin_role_users表没有主键怎么写入数据呢

没有主键为啥不能写入数据

Model::create(['a' => 'a']);Copy

只要不使用主键相关的 getKey, 或者模型实例更新，和普通模型一样

public $incrementing = false

为啥不行呢？我的代码 AdminRoleUsers::create (['role_id' => $roleId, 'user_id' => $user->id, 'created_at' => date ('Y-m-d H:i:s'), 'updated_at' => date ('Y-m-d H:i:s')]); 报错如下： Illuminate\Database\Eloquent\MassAssignmentException: Add [role_id] to fillable property to allow mass assignment on [App\Models\api\AdminRoleUsers]. in file D:\phpstudy_pro\WWW\laravel\vendor\laravel\framework\src\Illuminate\Database\Eloquent\Model.php on line 433 ......

我试试
