我试图在Sequelize中插入新行，但是无论我尝试什么，Sequelize都不会返回刚刚保存的自动递增行的ID。这是我的代码：
if (isDefined(jsonObject.id) && jsonObject.id == 0) {
let databaseObject = Database.getInstance().getModel(objectName).build(jsonObject);
//databaseObject.isNewRecord = true;
// Does not exist
//databaseObject.setNew(true);
transform.setNew(true);
transform.setJsonObject(jsonObject);
transform.setDatabaseObject(databaseObject);
return transform.populateJoins()
//.then(() => transform.baseMetadata())
//.then(() => transform.metadata())
.then(() => transform.baseExtract())
.then(() => transform.extract())
//.then(() => transform.clean())
.then(() => {
console.log('DATABASE OBJECT PRE SAVE: ');
console.log(transform.getDatabaseObject());
return transform.getDatabaseObject().save({
returning: true
});
}) // function () { return ; }
.then((data) => {
if (data instanceof sequelize.ValidationError) {
for (var field in data) {
this.addError(res.locals, ErrorCode.InvalidValue, field + ': ' + data[field]);
}
return false;
} else {
return Database.getInstance().getConnection().query('SELECT LAST_INSERT_ID();')
.then((row) => {
console.log('LAST INSERT ID: ');
console.log(row);
transform.getDatabaseObject().set('id', row[0]);
return transform.getDatabaseObject();
});
}
})
//.then(() => transform.getDatabaseObject()) // function () { return ; }
.then((data) => {
//console.log('Data is ' + typeof data);
console.log('NEW POST json: ');
console.log(jsonObject);
console.log('NEW POST data: ');
console.log(data);
console.log(data.get('id'));
if (jsonObject['id'] == data.get('id')) {
this.addError(res.locals, ErrorCode.InvalidValue, 'New object provided did not auto-increment.');
return false;
}
let dtoObject = {};
//for (var i in data.dataValues) {
// dtoObject[toCamelCase(i)] = data.get(i);
//}
for (let i in transform.columns) {
dtoObject[i] = data.get(transform.columns[i].name);
}
//if (jsonObject.id == data.get('id')) {
// throw new FrontendError(ErrorCode.InvalidValue, 'New object provided did not auto-increment.');
//}
res.locals.retval.addData(dtoObject);
但是，我总是收到New object provided did not auto-increment.异常，因为尽管返回的数据库对象保存到我的数据库中（ID 273567），其ID始终为0：

看起来我正在用变量覆盖isNewRecord方法，但是我删除了该代码，但似乎未进行任何更改。

我在bulkCreate上遇到了类似的问题。选项returning: true帮助了我。
我的代码：
return EventLog.bulkCreate(records, {
returning: true
});

这是从Sequelize获取自动增量主键的最简单的解决方案。这是一个非常丑陋的解决方案，但如果可行，它将奏效。
return Database.getInstance().getConnection().transaction((t) => {
return transform.getDatabaseObject().save({
transaction: t
})
.then((data) => {
if (data instanceof sequelize.ValidationError) {
for (var field in data) {
this.addError(res.locals, ErrorCode.InvalidValue, field + ': ' + data[field]);
}
return false;
} else {
return Database.getInstance().getConnection().query('SELECT LAST_INSERT_ID() as `id`;', { transaction: t, type: sequelize.QueryTypes.SELECT })
.then((row) => {
console.log('LAST INSERT ID: ');
console.log(row);
transform.getDatabaseObject().set('id', row[0]['id']);
transform.getDatabaseObject().setDataValue('id', row[0]['id']);
console.log('DATABASE OBJECT POST SAVE: ');
console.log(transform.getDatabaseObject());
return transform.getDatabaseObject();
});
}
})
})
