How to send a List<T> to the client

[Assambra]

I didnt find only one time a example how to use responseFactory.newArrayResponse(), but this example is nested with other functions so its to hard to figured out what i realy need to polish this values to send over the network.

I want to send a List with this values:

public class Character {
    @EzyId
    Long id;

    Long accountId;

    String name;
    String sex;
    String race;
    String model;
}

@EzyDoHandle(Commands.CHARACTER_LIST)
    public void characterList(EzyUser user)
    {
        logger.info("user {} request character list", user.getName());

        responseFactory.newArrayResponse()
                .command(Commands.CHARACTER_LIST)
                .data(
                        newArrayList(
                                characterService.getAllCharacters(user)
                        )
                )
                .user(user)
                .execute();
    }

What extra files i need (response, model, ModelToResponseConverter)and how have they to look, i tryed a lot but allways same error: Caused by: java.lang.IllegalArgumentException: has no writer for class com.assambra.game.common.entity.Character

Next question on the client side i use the following to reseive the data is this correct?

private void OnCharacterListResponse(EzyAppProxy proxy, EzyArray data)
    {
        if(data.isEmpty())
            GameManager.Instance.ChangeScene(Scenes.CreateCharacter);
        else
        {
            GameManager.Instance.ChangeScene(Scenes.SelectCharacter);
            for (int i = 0; i < data.size(); i++)
            {
                EzyObject item = data.get<EzyObject>(i);
                EzyArray character = item.get<EzyArray>("characters");

                CharacterInfo characterInfo = new CharacterInfo();
                characterInfo.id = character.get<long>(0);
                characterInfo.accountId = character.get<long>(1);
                characterInfo.name = character.get<string>(2);
                characterInfo.sex = character.get<string>(3);
                characterInfo.race = character.get<string>(4);
                characterInfo.model = character.get<string>(5);

                GameManager.Instance.characterInfos.Add(characterInfo);
            }
        }
    }

You need to add @EzyArrayBinding to Character, you can take a look docs here: https://youngmonkeys.org/ezyfox-library/guides/ezyfox-binding-marshal-unmarshal

i've added

@Data
@EzyCollection
@EzyArrayBinding
public class Character {
    @EzyId
    Long id;

    Long accountId;

    String name;
    String sex;
    String race;
    String model;
}

but now i get some error without sending response if i only try to read the List from the database with:

List<Character> chars = characterService.getAllCharacters(user);

public List<Character> getAllCharacters(EzyUser user) {
        Account account = accountRepo.findByField("username", user.getName());

        return characterRepo.findListByField("accountId", account.getId());
    }

Error: Caused by: com.tvd12.ezyfox.binding.exception.EzyReadValueException: can't read value: {accountId=2, race=Humanoid, sex=female, name=Assambra, model=äsldkfälskdfälskdj, _id=1} to: com.assambra.game.common.entity.Character

Error: Caused by: java.lang.ClassCastException: com.tvd12.ezyfox.entity.EzyHashMap cannot be cast to com.tvd12.ezyfox.entity.EzyArray

Hmm, because you're using this class for the both mongodb entity and response, you should not do that, you need to remove @EzyArrayBinding from the class, create a new response class and convert from entity to response

Thanks again and you can close the issue.

CharacterListModel:
@Getter
@Builder
@EzyArrayBinding
public class CharacterListModel {
    Long id;
    Long accountId;
    String name;
    String sex;
    String race;
    String model;
}

CharacterController:

@EzyDoHandle(Commands.CHARACTER_LIST)
    public void characterList(EzyUser user)
    {
        logger.info("user {} request character list", user.getName());

        responseFactory.newArrayResponse()
                .command(Commands.CHARACTER_LIST)
                .data(
                        convert(characterService.getAllCharacters(user))
                )
                .user(user)
                .execute();
    }

private CharacterListModel[] convert(List<Character> characters)
    {
        CharacterListModel[] chars = new CharacterListModel[characters.size()];

        int i=0;
        for (Character character : characters) {
            CharacterListModel characterListModel = CharacterListModel.builder()
                    .id(character.getId())
                    .accountId(character.getAccountId())
                    .name(character.getName())
                    .sex(character.getSex())
                    .race(character.getRace())
                    .model(character.getModel())
                    .build();

            chars[i] = characterListModel;
            i++;
        }
        return chars;
    }
