Question

我使用自动生成的函数“ addXXXs”收到错误的查询

型号：

module.exports = (sequelize, types) => {
    return sequelize.define('Product', {
        internal_code:{type:types.STRING},
        name:{type:types.STRING},
        description:{type:types.STRING},
        unit:{type:types.STRING},
        precio:{type:types.DECIMAL},
        alicuota:{type:types.DECIMAL},
        stock:{type:types.INTEGER},
        service:{type:types.INTEGER}
    })
}

module.exports = (sequelize, types) => {
    return sequelize.define('Imageproduct', {
        image:{type:types.STRING}
    })
}

关系：

db.Imageproduct.belongsTo(db.Product);
db.Product.hasMany(db.Imageproduct);

查询：

product = await db.Product.create(my_product);
images  = await db.Imageproduct.bulkCreate(my_images_list);
assoc   = await product.addImageproducts(images);

生成的查询：

1 - Executing (default): INSERT INTO "Products" ("internal_code","name","description","unit","precio","alicuota","stock","service","createdAt","updatedAt") VALUES ('P007',' 
Guitarra electrica','Guitarra electrica','',32.1,0.21,5,0,'2019-04-01 21:30:17.498 +00:00','2019-04-01 21:30:17.498 +00:00') RETURNING *;                               

2 - Executing (default): INSERT INTO "Imageproducts" ("id","image","createdAt","updatedAt") VALUES (DEFAULT,'blabla.png','2019-04-01 21:30:17.591 +00:00','2019-04-01 21:30:
17.591 +00:00'),(DEFAULT,'blabla.jpg','2019-04-01 21:30:17.591 +00:00','2019-04-01 21:30:17.591 +00:00');                                                               

3 - Executing (default): UPDATE "Imageproducts" SET "ProductId"=3,"updatedAt"='2019-04-01 21:30:17.667 +00:00' WHERE "id" IN (NULL, NULL)

1和2是正确的，但是我希望在查询3的IN子句中有一些有效的ID，而不是NULL，实际上，我希望在查询3的IN子句中插入图像的ID。有人知道为什么会这样吗？

谢谢。

替换

images  = await db.Imageproduct.bulkCreate(my_images_list);

到

images  = await db.Imageproduct.bulkCreate(my_images_list, { returning:true });

这样，您可以在图像对象中获取新记录的ID。（仅限于PostgreSQL）

在Sequalize ORM中使用BelongTo / HasMany关联的错误查询
