我正在尝试在使用Sequelize的项目中通过表建立自定义。我有一个Plannings表和一个Tasks表。现在,我希望实现一个将两者关联的表,但是我想添加一个自定义列“ done”。运行sync()
时,似乎所有表都已正确设置。这是运行它以建立PlanningTask表的查询:
CREATE TABLE IF NOT EXISTS `PlanningTask`
(`done` TINYINT(1) NOT NULL, `PlanningId` INTEGER(11) , `TaskId` INTEGER(11) ,
PRIMARY KEY (`PlanningId`, `TaskId`),
FOREIGN KEY (`PlanningId`) REFERENCES `Plannings` (`id`) ON DELETE CASCADE ON UPDATE CASCADE,
FOREIGN KEY (`TaskId`) REFERENCES `Tasks` (`id`) ON DELETE CASCADE ON UPDATE CASCADE)
ENGINE=InnoDB;
以下是当前型号: task.js
module.exports = (sequelize, DataTypes) => {
const Task = sequelize.define('Task', {
id: {
type: DataTypes.INTEGER(11),
allowNull: false,
autoIncrement: true,
primaryKey: true
},
type: {
type: DataTypes.STRING,
allowNull: false
},
description: {
type: DataTypes.STRING,
allowNull: false
},
})
Task.associate = function(models) {
Task.belongsToMany(models.Planning, {
through: 'PlanningTask'
})
}
// Methods
return Task
}
planning.js
module.exports = (sequelize, DataTypes) => {
const Planning = sequelize.define('Planning', {
id: {
type: DataTypes.INTEGER(11),
allowNull: false,
autoIncrement: true,
primaryKey: true
},
title: {
type: DataTypes.STRING,
allowNull: false
}
})
Planning.associate = function (models) {
Planning.belongsTo(models.User, {
foreignKey: 'owner'
})
Planning.belongsToMany(models.Task, {
through: 'PlanningTask'
})
}
// Methods
return Planning
}
planningtask.js
module.exports = (sequelize, DataTypes) => {
const PlanningTask = sequelize.define('PlanningTask', {
done: {
type: DataTypes.BOOLEAN,
allowNull: false
}
}, {
timestamps: false,
freezeTableName: true
})
PlanningTask.associate = function (models) {
PlanningTask.belongsTo(models.Planning)
PlanningTask.belongsTo(models.Task)
}
// Methods
return PlanningTask
}
所有模型都加载了以下index.js文件:
const fs = require('fs')
const path = require('path')
const Sequelize = require('sequelize')
const config = require('../config/config')
const db = {}
const sequelize = new Sequelize(
config.db.database,
config.db.user,
config.db.password,
config.db.options
)
fs
.readdirSync(__dirname)
.filter((file) =>
file !== 'index.js'
)
.forEach((file) => {
const model = sequelize.import(path.join(__dirname, file))
db[model.name] = model
})
Object.keys(db).forEach(function (modelName) {
if ('associate' in db[modelName]) {
db[modelName].associate(db)
}
})
db.sequelize = sequelize
db.Sequelize = Sequelize
module.exports = db
我想知道订单是否可能存在一些问题(关联已在订单Planning,PlanningTask,Task中注册),但是当我更改订单时仍然无法使用。该表已正确创建,但是当我尝试使用Planning.add([task])输入Task时,它将运行以下查询:
SELECT `done`, `PlanningId`, `TaskId`
FROM `PlanningTask` AS `PlanningTask`
WHERE `PlanningTask`.`PlanningId` = 1 AND `PlanningTask`.`TaskId` IN (1);
因此,对于PlanningId,它尝试将'= 1'设置为正确,但是对于TaskId,它将使用'IN(1)',这是不正确的。在这种情况下,1是正确的任务ID。
在关联中我做错了什么吗,或者我尝试输入任务的方式是否有问题?
答案 0 :(得分:0)
我的错误。 “完成”列仍设置为必填,在我的测试中,我没有为此发送任何值,其余的工作正常。
