[HosseinKurd]

Hi As we know, we need to make our projects According to Design Patterns Standards. So How to use Composite Design Pattern with Sugar ORM The link below Explain it https://en.wikipedia.org/wiki/Composite_pattern

[colabug]

Looks like you have to save each item separately: https://github.com/satyan/sugar/issues/443

That said, not sure how complex the object can be/how deeply nested.

I'm facing the same problem so I use my own fk but it prevent from using SugarOrm.saveInTx() and make applications slower (because it now commit on every insertion).

public class Monster extends SugarRecord {
    @Expose
    @SerializedName("id")
    @Unique
    public int monster_id;// the sql table will be called monsterid (see sugarOrm doc)

    @Expose
    public String hp;

    @Expose
    public int defense;

    @Expose
    public int attack;

    @Expose
    public String name;

    @Expose
    public String sprite;
}

public class UserMonster extends SugarRecord {
    @Expose
    public Monster infos;

    @Expose
    public String level;

    @Expose
    public String surname;

    @Expose
    public String experience;

    public int fkmonster;//key for Monster<->UserMonster relationship
}

public void updateUserMonster(Response<UserMonsterResponse> response) {
    UserMonster.deleteAll(UserMonster.class);

    /*
    ** Since every 'Monster' were already saved, no need to call userMonster.info.save()
    ** Since calling Monster.saveInTx(response.body().monsters); cause
    **  Select.from(UserMonster.class).list().get(0).infos = null; to be null
    ** we manage our own fk
    */
    for (UserMonster userMonster : response.body().monsters) {
        userMonster.fkmonster = userMonster.infos.monster_id;
        userMonster.save();
    }
}
