node.js - 具有延迟约束的 Postgres Sequelize 事务不起作用

Question

目的:
我正在尝试在事务内的相关表中进行更改。

操作:
我已经更改了表中的约束以将它们设置为 DEFERRABLE INITIALLY DEFERRED 以便能够在事务内的引用表中提交。 Just like in this article.

所以在我的表中有两个 FK 约束:

Foreign-key constraints:
    "updaters_features_updater_id_fkey" FOREIGN KEY (updater_id) REFERENCES updaters(id) ON UPDATE CASCADE ON DELETE CASCADE DEFERRABLE INITIALLY DEFERRED
    "updaters_features_feature_id_fkey" FOREIGN KEY (feature_id) REFERENCES features(id) ON UPDATE CASCADE ON DELETE CASCADE DEFERRABLE INITIALLY DEFERRED

我开始交易:

sequelize.transaction({
    deferrable:  this.db.sequelize.Deferrable.SET_DEFERRED,
}, t => {
    //insert into updates table
    //insert into updates_features table 
})

它生成下一个 SQL 查询:

START TRANSACTION;
SET CONSTRAINTS ALL DEFERRED
SET SESSION TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;
INSERT INTO "public"."updaters" ("id","description","is_full","created_at","updated_at","android_model_id","version_from_id","version_to_id") VALUES (DEFAULT,'Description',true,'2019-12-18 09:46:21.272 +00:00','2019-12-18 09:46:21.272 +00:00',1,31,32) RETURNING *;
INSERT INTO "public"."updaters_features" ("created_at","updated_at","feature_id","updater_id") VALUES ('2019-12-18 09:46:21.267 +00:00','2019-12-18 09:46:21.267 +00:00',3,280),('2019-12-18 09:46:21.267 +00:00','2019-12-18 09:46:21.267 +00:00',5,280);

它因违反外键约束而失败 Key (updater_id)=(280) is not present in table "updaters".
我找不到问题，最奇怪的是，如果我从控制台复制 SQL 查询并在 psql 中手动运行它 - 一切都很好，我可以提交事务。

我在 this question 中寻找，但我有不同的问题。

UPD(应用事务代码的JS):

await this.withTransation({
    deferrable:  this.db.sequelize.Deferrable.SET_DEFERRED,
}, async(transaction) => {
    update = await this.dbModel.create({
        version_from_id: body.buildFrom,
        version_to_id: body.buildTo,
        android_model_id: body.modelId,
        description: body.description,
        isFull: body.isFull,
    }, {transaction});
    await this.db.UpdatersGroups.bulkCreate(body.groupIds.map((groupId) => ({
        feature_id: groupId,
        updater_id: update.id,
    })));
});

withTransaction 是我的抽象，我确信它可以正常工作(只需在 sequelize 中创建非托管事务)

Answer 1

第二个查询不在事务上下文中执行，因此添加 transaction 应该会有所帮助:

...
await this.db.UpdatersGroups.bulkCreate(body.groupIds.map((groupId) => ({
    feature_id: groupId,
    updater_id: update.id,
}), { transaction })); // transaction here is applied.
