Question

我是sequelize的新手，每次创建一个新的＆＃34; Rider＆＃34;我都试图将这个名字的第一个字母大写。所以它看起来像我的桌子。我还没能做到：

这是我的模特：

const db = require("./db");
const Sequelize = require("sequelize");

//(w / WSL ranking, Last tournament won, Country, favorite wave, current board).
const Rider = db.define("rider", {
  name: {
    type: Sequelize.STRING,
    allowNull: false
  },
  country: Sequelize.STRING,
  wsa: {
    type: Sequelize.INTEGER,
    allowNull: false
  },
  currentBoard: {
    type: Sequelize.STRING,
    allowNull: false
  },
  favWave: Sequelize.STRING,
  lastTournamentWon: Sequelize.STRING,
  img: {
    type: Sequelize.TEXT,
    defaultValue:
      "no_found.png"
  }


});

Rider.beforeCreate = () => {
  return this.name[0].toUpperCase() + this.name.slice(1);
}

module.exports = Rider;

当我创建一个新行时，这个名称并没有大写，我还没有找到原因？我是否必须将实例和回调函数作为我的钩子的参数传递？

如@iwaduarte的评论所述，您需要传递实例，如下所示

const User = sequelize.define('user', {
  username: Sequelize.STRING,
});

User.hook('beforeCreate', (user, options) => {
  user.username = user.username.charAt(0).toUpperCase() + user.username.slice(1);
});

sequelize.sync({ force: true })
  .then(() => User.create({
    username: 'one',
  }).then((user) => {
    console.log(user.username);
  })
);

保存在数据库 - 实例挂钩之前，请继续使用大写名称
