[英]Sequelize Insert Cascade hasMany
Here again now having problem to insert hasMany.现在再次有问题插入hasMany。 tables Bill > BillDetail, im using freezeTableName: true to keep table in singular way
表格 Bill > BillDetail,我使用 freezeTableName: true 以单一方式保存表格
Relations from Bill Model比尔模型的关系
Bill.associate = (models) => {
Bill.hasMany(models.BillDetail, { foreignKey: "idBill" });
};
This is the code to insert Bill and create BillDetail with Bill "id", but ignore BillDetails unless i add Bill.belongsTo BillDetail but i will insert just the first object of BillDetail这是插入 Bill 并使用 Bill "id" 创建 BillDetail 的代码,但忽略 BillDetails 除非我添加 Bill.belongsTo BillDetail 但我只会插入 BillDetail 的第一个对象
Bill.create({
idClient: 1,
description: "new project",
BillDetail: [
{ idService: 1 },
{ idService: 2 }
],
},
{ include: BillDetail });
im following the guide, but i don't know what im missing.我遵循指南,但我不知道我错过了什么。 https://sequelize.org/master/manual/creating-with-associations.html

You indicated include
model with single name but you need to indicate with plural:您表示
include
具有单一名称的模型,但您需要用复数表示:
Bill.create({
idClient: 1,
description: "new project",
BillDetails: [
{ idService: 1 },
{ idService: 2 }
],
},
{ include: BillDetail });
compare with the example from the docs:与文档中的示例进行比较:
Product.create({
id: 1,
title: 'Chair',
tags: [ // pay attention there is **tags** and not **tag**
{ name: 'Alpha'},
{ name: 'Beta'}
]
}, {
include: [ Tag ]
})
