Sequelize Nodejs中的时区问题

Question

I want Sequelize to use my local time for reading and writing to database. in Sequelize config file I added timezone: "+04:30", but it is just for writing in database. for writing in database when i add

 dialectOptions: { useUTC: false, // -->Add this line. for reading from database },

i get this error:

Ignoring invalid configuration option passed to Connection: useUTC. This is currently a warning, but in future versions of MySQL2, an error will be thrown if you pass an invalid configuration option to a Connection

full config file:

 const Sequelize = require("sequelize"); const sequelize = new Sequelize("db", "root", "", { dialect: "mysql", port: process.env.SQL_PORT, host: "localhost", charset: "utf8", collate: "utf8_persian_ci", logging: false, dialectOptions: { useUTC: false, // -->Add this line. for reading from database }, timezone: "+04:30", });

Answer 1

Finally I fixed it by getter in my model:

createdAt: {
  type: Sequelize.DATE,
  defaultValue: moment(new Date()).format("YYYY-MM-DD HH:mm:ss"),
  get: function () {
    var isoDateString = new Date(this.getDataValue("createdAt"));
    return new Date(
      isoDateString.getTime() -
        isoDateString.getTimezoneOffset() * 60 * 1000
    );
  },

},

and change my config file to:

const Sequelize = require("sequelize");

const sequelize = new Sequelize("db", "root", "", {
dialect: "mysql",
port: process.env.SQL_PORT,
host: "localhost",
charset: "utf8",
collate: "utf8_persian_ci",
logging: false,
timezone: "+04:30",
});
