如何在我的模型中定义 mysql 中另一个表的 id 数组并进行续集
我在express.js、node.js、mysql和sequelize中创建了一个api。
我有两个模型:自定义字段和客户类型
这是我的客户类型模型:
module.exports = (sequelize, DataTypes) => {
const CustomerType = sequelize.define("customerType", {
name: {
type: DataTypes.STRING,
allowNull: false
},
description: {
type: DataTypes.STRING,
allowNull: false
},
user_id: {
type: DataTypes.STRING,
allowNull: false
}
})
return CustomerType
}
还有我的自定义字段模型:
const customerType = require('./customerTypeModel')
module.exports = (sequelize, DataTypes) => {
const CustomField = sequelize.define("customField", {
customer_type_ids: [
{
type: DataTypes.INTEGER,
references: {
model: customerType,
key: "id"
}
}
],
user_id: {
type: DataTypes.STRING,
allowNull: false
},
system_name: {
type: DataTypes.STRING,
allowNull: true
},
title: {
type: DataTypes.STRING,
allowNull: true
},
type: {
type: DataTypes.STRING,
allowNull: true
},
required: {
type: DataTypes.BOOLEAN,
allowNull: true
},
})
return CustomField
}
我需要在我的 customField 表中包含来自 customerType 表的 id 数组。 例如,我需要获取这样的 json:
{
"id": 1
"customer_types_ids": [
{
"id": 1,
"name": "Customers",
"description": "Customers",
"user_id": "123456"
},
{
"id": 2,
"name": "Leads",
"description": "Leads",
"user_id": "123456"
}
],
"user_id": "123456",
"system_name": "firstname",
"title": "Firstname",
"type": "text",
"required": true
}
我应该如何构建我的自定义字段模型才能获得这样的 json 作为回报?
感谢您的帮助 !
I create an api in express.js, node.js, mysql and sequelize.
I have two models : Custom fields and Customer Types
Here is my customer type model :
module.exports = (sequelize, DataTypes) => {
const CustomerType = sequelize.define("customerType", {
name: {
type: DataTypes.STRING,
allowNull: false
},
description: {
type: DataTypes.STRING,
allowNull: false
},
user_id: {
type: DataTypes.STRING,
allowNull: false
}
})
return CustomerType
}
And there is my custom fields model :
const customerType = require('./customerTypeModel')
module.exports = (sequelize, DataTypes) => {
const CustomField = sequelize.define("customField", {
customer_type_ids: [
{
type: DataTypes.INTEGER,
references: {
model: customerType,
key: "id"
}
}
],
user_id: {
type: DataTypes.STRING,
allowNull: false
},
system_name: {
type: DataTypes.STRING,
allowNull: true
},
title: {
type: DataTypes.STRING,
allowNull: true
},
type: {
type: DataTypes.STRING,
allowNull: true
},
required: {
type: DataTypes.BOOLEAN,
allowNull: true
},
})
return CustomField
}
I need to have in my customField table an array of id from the customerType table.
For exemple i need to get a json like this :
{
"id": 1
"customer_types_ids": [
{
"id": 1,
"name": "Customers",
"description": "Customers",
"user_id": "123456"
},
{
"id": 2,
"name": "Leads",
"description": "Leads",
"user_id": "123456"
}
],
"user_id": "123456",
"system_name": "firstname",
"title": "Firstname",
"type": "text",
"required": true
}
How should I structure my custom field Model to be able to have a json like this in return?
Thanks for your help !

我假设您期望
CustomField
和CustomerType
之间存在一对多关系。在本例中,CustomerType
拥有该关系,因此在CustomerType
的关系表中存在对CustomField
的引用,称为customFieldId
代码>.这应该定义两个具有一对多关系的关系表。以下代码可用于加载
CustomField
及其所有CustomerType
。I assume you're expecting a One-to-Many relationship between
CustomField
andCustomerType
. In this case,CustomerType
owns the relation, so there is a reference toCustomField
in the relational table ofCustomerType
calledcustomFieldId
.This should define two relational tables with a One-to-Many relationship. The following code can be used to load a
CustomField
with all itsCustomerType
