Laravel validation get value from a column and compare it to another table column

Question

I have the following tables:

- companies
- users
- departments
- services

We have the following structure:

A user belongs to a company
A company has many departments
One department has multiple services.

The problem is that I want to validate the service department that has a specific company_id flag using only the service ID.

Database:

company

| id | name         |
| 1  | Company 1    |
| 2  | Company 2    |

user

| id | name         | company_id |
| 1  | User 1       | 1          |

departments

| id | name         | company_id |
| 1  | Department 1 | 1          |
| 2  | Department 2 | 2          |

services

| id | name      | departments_id |
| 1  | Service 1 | 1              |
| 2  | Service 2 | 2              |

The endpoints looks like this:

Looged in user belongs to Company 1

$app->delete('/{id}', ['uses' => 'ServicesController@deleteService']);

Delete service method

public function deleteService($id, Request $request)
{
    $request['id'] = $id;
    $this->validate($request, [
        'id' => 'required|exists:services,id',
    ]);

    $result = Service::deleteService($id, $this->user->company_id);
    return response()->json($result);
}

The user of Company 1 should not be able to delete the Service 2 . How can I achieve this?

Thanks.

最可监督的方式是编写自定义验证器

You can do it using policies in Laravel, check the docs

it will be something like this

    $request['id'] = $id;
$this->validate($request, [
    'id' => 'required|exists:services,id',
    ]);


$this->authorize('delete', $id); // will check if user can delete the company as the needed logic. 

$result = Service::deleteService($id, $this->user->company_id);
return response()->json($result);
