防止sequelize插入时间戳

有许多类似的问题，但我已经尝试了大多数建议的解决方案，没有运气 .

我已经有了数据库（mysql）所以我跳过了模型定义并使用了sequelize-auto（programmatic） . 第一个问题是不推荐使用的依赖项（sequelize-auto使用sequelize v3） .

通过sequelize-auto（sequelize v3）从现有数据库生成的模型：

{
   "id":{
      "type":"INT(10) UNSIGNED",
      "allowNull":false,
      "defaultValue":null,
      "primaryKey":true,
      "foreignKey":{
         "source_table":"db_name",
         "source_schema":"db_name",
         "target_schema":null,
         "constraint_name":"PRIMARY",
         "source_column":"id",
         "target_table":null,
         "target_column":null,
         "extra":"",
         "column_key":"PRI",
         "isPrimaryKey":true
      }
   },
   "name":{
      "type":"VARCHAR(255)",
      "allowNull":false,
      "defaultValue":null,
      "primaryKey":false
   },
   "start":{
      "type":"DATE",
      "allowNull":false,
      "defaultValue":null,
      "primaryKey":false
   },
   "end":{
      "type":"DATE",
      "allowNull":false,
      "defaultValue":null,
      "primaryKey":false
   },
   "active":{
      "type":"TINYINT(1)",
      "allowNull":false,
      "defaultValue":"0",
      "primaryKey":false
   },
   "updated_at":{
      "type":"TIMESTAMP",
      "allowNull":false,
      "defaultValue":"CURRENT_TIMESTAMP",
      "primaryKey":false
   }
}

create.sql中的列 updated_at 定义：

updated_at` TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

所以生成的模型完全缺失 ON UPDATE CURRENT_TIMESTAMP .

生成模型后，我将它们与express一起用于sequelize v4 .

幸运的是，可以在模型定义中设置 timestamps: false ，但它不起作用 . 我也没试过 updated_at: false （连同 underscored: true ）（它根本没有效果 - 仍然是同样的错误） .

唯一有效的方法是在定义之前从模型中完全删除 updated_at 键 . 之后，所有工作都像魅力，但我需要过滤此列，因此它不是解决方案 .

model.js：

const SequelizeAuto = require("sequelize-auto");
const Sequelize = require("sequelize");
const config = require("../conf/config.json");


const Op = Sequelize.Op; // fixed sequelize v3 bug
var options = {
    database: config.db.name,
    username: config.db.username,
    password: config.db.password,
    host: config.db.host,
    dialect: config.db.dialect,
    operatorsAliases: Op,
    pool: {
        max: 5,
        min: 0,
        idle: 10000
    },
    directory: false, // prevents the program from writing to disk
    //port: 'port',
    //tables: [],
    additional: {
        underscored: true,
        timestamps: false
    }
};

const modelOptions = {
    bb_campaign: {
        alias: "campaign"
    },
    bb_campaign_stats: {
        alias: "stat"
    }
};

function getTableOptions(tableName) {
    return {
        freezeTableName: true,
        underscored: true,
        timestamps: false,
        updated_at: false,
        tableName: tableName
    }
}

// SequelizeAuto uses old sequelize v3 + mysql (not mysql2)
var db_map = new SequelizeAuto(config.db.name, config.db.username, config.db.password, options);

module.exports = new Promise((resolve, reject) => db_map.run((err) => {
    if (err) {
        reject(err);
        return;
    }

    // atm session is closed, we need to create new
    // https://github.com/sequelize/sequelize-auto/issues/243
    let db = {};
    db.sequelize = new Sequelize(options);
    for (tableName in db_map.tables) {
        let alias = tableName in modelOptions ? 
            modelOptions[tableName].alias : tableName;

        db[alias] = db.sequelize.define(alias, db_map.tables[tableName], getTableOptions(tableName));
        console.log('Registered model for table %s as %s.', tableName, alias);

        // asociace ted nepotrebujeme
        //if (tableName in db_map.foreignKeys) {}
    }
    resolve(db);
}));

插入：

Executing (default): INSERT INTO `bb_campaign` (`id`,`name`,`start`,`end`, `active`,`updated_at`) VALUES ('216450','item name','2018-12-02','2018-12-08',1,'CURRENT_TIMESTAMP') ON DUPLICATE KEY UPDATE `id`=VALUES(`id`), `name`=VALUES(`name`), `start`=VALUES(`start`), `end`=VALUES(`end`), `active`=VALUES(`active`);

数据库错误：

未处理的拒绝SequelizeDatabaseError：日期时间值不正确：第1行的列'updated_at'为'CURRENT_TIMESTAMP'

有什么建议？
