Thanks for the advices, @goldtaste .

About the foreach... inside it there is more than one service related to the members. Should I have pass the list and have the same loop on both services? Something like this:

... some code ...
$this->addMemberToContract->execute(id, $data['member_list'])

$this->addMembershipCardToMember->execute(id, $data['member_list'])
... some code ...

And then I make the loop on the services? Wouldn't that be redundant? Or its ok to do that in this scenario?

About the services, I'm trying to make them more loose. Maybe have a class 'CreateContractManager' (or some better name?) that will be called for the controller. And then this manager will call all the services necessary for his execution. The services would just make one action without worry about anything. The worry for the execution flux would be on the manager class hands.

Do this make sense? Am I separating the business logic too much? I tried to search for patterns like this but found nothing...

Thanks for the tips, @bugsysha

I didn't know about this 'responsable', so I will study about it and how apply it on my case.

About the change on the __construct(), what are the benefits of the change?

Started a new Conversation Help With Pattern For Project

I'm trying to figure it out the best approach to develop a project that I'm working on (and that have the possibility of growing). Maybe you guys can give some advice, some tips.

On the application, there will be a section to create a contract. At the same time, the app should insert the members of contract, membership cards for each member, a sale (with price) of the contract, a sale comission for the seller, a group of monthly payments. All of this coming from one single form.

I was thinking on let the controllers on the clean side, dividing responsabilities with others layers. The idea until now is explained with some sample codes:


use App\Http\Requests\CreateContractRequest;
use App\Services\CreateContractService;

class ContractController {

    public function create(CreateContractRequest $request, CreateContractService $service) {
        $contract = $service->execute($request->only(
            ... other columns ...
        return response()->json($contract, 201);


use App\Repositories\ContractRepository;

use App\Services\AddMemberToContractService;
use App\Services\AddMembershipCardToMemberService;
use App\Services\CreateSaleService;

class CreateContractService {

    public function __construct() {
        $this->contractRepo = new ContractRepository();
        $this->addMemberToContract = new AddMemberToContractService();
        $this->addMembershipCardToMember = new AddMembershipCardToMemberService();
        $this->createSale = new CreateSaleService();
    public function execute(array $data) {
        // Create contract
        $new_contract = $this->contractRepo->create($data);
        foreach ($data['member_list'] as $m) :
            // Add members
            $new_member = $this->addMemberToContract->execute($id_contract, $m);
            // Create membership cards for members
            $new_card = $this->addMembershipCardToMember->execute($new_member);
        // Create sale
        $new_sale = $this->createSale->execute($data);
        ... others inserts ...
        return $new_contract;



use App\models\Contracts;

class ContractRepository {

    public function create(array $data) {
        $o_contract = new Contracts();
        $o_contract->cod_plan = $data['cod_plan'];
        $o_contract->cod_seller = $data['cod_seller'];
        ... other columns ...
        return $o_contract;


With that, I have some questions.

  1. This approach make sense? Is the better way of do it? I'm trying to make the code more reusable and decoupled.

  2. Can I (and should I) separate more the services and the logic behind them?

  3. How should I handle the errors? Use exceptions? Even for ajax requests? Should I verify for errors on each part of the 'execute' method and return messages mannually?

  4. If I have to work with exceptions, how can make my own exceptions?

  5. If some part of the code result on a error, how can I undo the inserts already done to make sure that the user can utilize the form to try the same insertion again?

  6. On the services, should I only return data objects, booleans or responses?

  7. The responses are better just in the controllers?

  8. How should I handle errors on the repositories and pass the same errors to the services?

  9. With this structure, can I make tests more easily?

  10. Its hard to use the same code to a web and a api version of the app?

I appreciate the help.

(Sorry if the english is not that good...)
