在定义模型之后是否需要Model.init()？续写-打字记录

Question

在定义了一个模型之后，我找不到任何关于必须使用sequelize-typescript. ()的地方，我认为我做错了什么，或者我必须使用sequelize而不是Model.init来完成它在代码中，im试图使用类转换器(以及失败的xd)，所以只需忽略它。所以，后缀会抱怨我的模型没有定义，为了解决这个问题，我把Model.init()放在上面，我做的是正确的吗？

import { DataTypes } from 'sequelize';
import sequelize from '@shared/infra/sequelize/index';
import { Table, Model, Column } from 'sequelize-typescript';
import { Exclude } from 'class-transformer';

@Table({ tableName: 'acesso_api' })
export default class User extends Model {
  @Column({ primaryKey: true })
  id: number;

  @Column
  nome: string;

  @Column
  @Exclude()
  password: string;

  @Column
  @Exclude()
  password_hash: string;

  @Column
  cliente: string;

  @Column({ defaultValue: 0 })
  @Exclude()
  admin: number;
}

User.init(
  {
    id: {
      type: DataTypes.INTEGER,
      autoIncrement: true,
      primaryKey: true,
    },
    nome: {
      type: DataTypes.STRING(45),
    },
    password: {
      type: DataTypes.STRING(45),
    },
    password_hash: {
      type: DataTypes.STRING(100),
    },
    cliente: {
      type: DataTypes.STRING(45),
    },
    admin: {
      type: DataTypes.INTEGER(),
      defaultValue: 0,
    },
  },
  {
    tableName: 'acesso_api',
    sequelize,
  },
);

顺便说一句，我的默认连接就是这样解决的(是的，在找到模型时没有任何问题)：

import { Sequelize } from 'sequelize-typescript';

export default new Sequelize({
  dialect: 'mysql',
  host: process.env.HOST,
  username: process.env.POLO_USERNAME,
  password: process.env.PASSWORD,
  database: 'some_DB',
  repositoryMode: true,
  models: [`${__dirname}./src/modules/**/infra/sequelize/entities/*.ts`],
  port: 3306,
  define: {
    timestamps: false,
    underscored: true,
    freezeTableName: true,
  },
});

这是给我的错误消息，如果我没有Model.init()它(注入消息是因为注射器，所以忽略它)：

我想我想出来了，就像那样。“后缀-类型记录”不会自动插入您创建的模型，因此您必须手动创建，这实际上是好的，因为您可以选择什么时候要插入它。目前，我正在开发一个需要多个数据库连接的应用程序，并且可以在任何时候输入模型，这只是为我节省了时间。
