it is possible to sequelize save items only after all models update?

[ssdk86]

In my models I have One-To-Many relationships, and want to update and save all in one try..catch function to define if error there.

Team.hasMany(Player);
Player.belongsTo(Team);

const MyTeam = await Team.findOne({
  where: {
    name: "chikago"
  },
  include: Playes
});

result in json like this

MyTeam": {
    "id" : 5,
    "name" : "chikago",
    "title"  : "lets'go Chikago!!!"

    "Players": [
        {
            "id": 1,
            "name": "bob"
            "years": 18
        },
        {
            "id": 2,
            "name": "tom"
            "years": 20
        },
    ]
};

so in MyTeam I have result with team and players related to it.
now i want to edit some values in MyTeam entity and in players, and create new player, then save all this with try...catch handling error;

for exapmle:

MyTeam.title = "here are we go";
try {
    await MyTeam.save();
} catch (error) {
    console.log(error);
}

let newPlayer = new Player({...});
try {
    await newPlayer.save();
} catch (error) {
    console.log(error);
};

// here many other code ...


try {
    MyTeam.Players.map(async player => {
        player.years = player.years + 1;
        await player.save();
    });
} catch (error) {
    console.log(error);
}

but there is a way if i need to save all my editing some like

let entityManager = new Sequeilize('entityManager');
MyTeam.title = "here are we go";
entityManager.add(MyTeam);

let newPlayer = new Player({...});
entityManager.add(newPlayer);

MyTeam.Players.map(player => {
    player.years = player.years + 1;
    entityManager.add(player);
});

try {
    await entityManager.save();
} catch (error) {
    console.log(error);
};

---

I an trying to do something like this, as described in #5471 (comment)
but model saving and updated as they push to array

let savingEntities = [];
MyTeam.title = "here are we go";
savingEntities.push(MyTeam);

let newPlayer = new Player({...});
savingEntities.push(newPlayer);

MyTeam.Players.map(player => {
    player.years = player.years + 1;
    savingEntities.push(player);
});

try {
    await Promise.all(savingEntities);
} catch (error) {
    console.log(error);
};

Please use Github Issue Tracker only for reporting bugs, requesting new features or discussions. Ask questions on Stackoverflow sequelize.js tag or Slack. While I would like to help answer any questions but it still take too much time.

If you are reporting a bug please isolate it as SSCCE, present it nicely and follow issue template. This will help maintainers and contributors understand your issue quickly.

If you are requesting a feature spend some time to properly present your use case with some examples, current and expected outcome.

( What is SSCCE ? You can find template for Sequelize here )

A few good example of SSCCE

1. ResourceRequest timed out - connection not reestablished after db restarted #8014 (comment)
2. removeAttribute('id') results in undefined: null data value #7318 (comment)
3. toJSON converting booleans to "t" (true) or "f" (false) #8749 (comment)
