下面是我在 Hooks 中用于更新两个对象的 updatedAt
列的代码:
hooks: {
afterUpdate: (group, options, callback) => {
console.log("groudId " + groupId + " options " + options)
},
afterCreate: (member, options, callback) => {
return new Promise((resolve, reject) => {
sequelize.models.Group.findOne({
where: {
id: member.group_id
}
}).then((group) => {
if (group) {
var date = new Date();
console.log("BEFORE group.updatedAt " + group.updatedAt)
group.dataValues.updatedAt = new Date()
console.log("CHANGED group.updatedAt " + group.updatedAt)
group.save().then((Group) => {
if (Group) {
console.log("UPDATED Group.updatedAt " + Group.updatedAt)
console.log("UPDATED group.updatedAt " + group.updatedAt)
resolve(Group)
} else {
console.log("NO GROUP Found")
return reject(group.id)
}
}).catch((error) => {
return (error)
})
} else {
return reject(id)
}
}).catch((error) => {
return (reject)
})
})
}
控制台日志:
BEFORE group.updatedAt Fri Feb 17 2017 17:36:00 GMT-0800 (PST)
CHANGED group.updatedAt Tue Feb 28 2017 14:00:17 GMT-0800 (PST)
UPDATED Group.updatedAt Tue Feb 28 2017 14:00:17 GMT-0800 (PST)
UPDATED group.updatedAt Tue Feb 28 2017 14:00:17 GMT-0800 (PST)
BEFORE group.updatedAt Fri Feb 17 2017 17:36:00 GMT-0800 (PST)
CHANGED group.updatedAt Tue Feb 28 2017 14:00:19 GMT-0800 (PST)
UPDATED Group.updatedAt Tue Feb 28 2017 14:00:19 GMT-0800 (PST)
UPDATED group.updatedAt Tue Feb 28 2017 14:00:19 GMT-0800 (PST)
虽然我认为日志看起来是正确的,但为什么数据库中的实际对象没有更新为新的
updatedAt
值?或者是否有 更简单的 方法来更新对象 updatedAt
列? 最佳答案
以上都不适合我,所以我不得不改用模型方法:
await MyModel.update({ updatedAt }, { where: { id: instance.id }, silent: true });
