Php Laravel-调用存储库中未定义的方法

为了保持代码的干净性和可扩展性，我创建了一个

EloquentUserRepository

这是我的雄辩记述：

但当我在播种机上使用它时：

我得到：

BadMethodCallException]调用未定义的方法 Illumb\Database\Query\Builder:：assignRole（）

这是

create

方法：

/**
     * Create new resource
     *
     * @param array $data
     * @return mixed
     */
    public function create(array $data)
    {
        return $this->model->create($data);
    }

如果我

dd

我得到

用户

模型：

App\Models\User {#605

    0 => "first_name"
    1 => "last_name"

问题在于

assignRole

是

elountituserrepository

类的一种方法。因此，如果

$a

是

App\Models\User

的实例，

$a->assignRole（）

不存在

如果要通过存储库分配角色，必须调用存储库上的方法：

$this->userRepository->assignRole($adminRole);

前提是该方法将获得对实际

用户

模型的访问权，并为其分配角色。如果不是这样，您可以将实际的

模型

作为参数传递，并在方法中分配角色：

//pass both role and model to the repository
public function assignRole(Role $role, Model $user)
{
    //here assign the role to the user
}

因此，您的代码将是：

$a = $this->userRepository->create($admin);
$this->userRepository->assignRole($adminRole, $a);

EloquentUserRepository:：创建什么

返回？它似乎是

illumb\Database\Query\Builder

的一个实例，它从错误中返回

App\Models\User

，它似乎试图在

illumb\Database\Query\Builder

上调用

assignRole

，因此可能在循环的某个迭代中出错了？在调用

assignRole

之前，是否可以尝试在每次迭代中记录

$a

的内容？即：

Log:：debug（print_r（$a，true））

使用logi更新了问题，请参见

assignRole

是

EloquentUserRepository

类的一种方法。因此，如果

$a

是

App\Models\User

的实例，

$a->assignRole（）

不存在。或者您也有

App\Models\User:：assignRole

方法？

//pass both role and model to the repository
public function assignRole(Role $role, Model $user)
{
    //here assign the role to the user
}

$a = $this->userRepository->create($admin);
$this->userRepository->assignRole($adminRole, $a);
