安装

npm install egg-mysql-sequelize-auto --save-dev

命令行说明

mysql-sequelize-auto -h <host> -d <database> -p [port] -u <user> -x [password] -o [./path/to/model] -t [tableName]

Options:
  -h, --host        IP/Hostname for the database.                       [string]
  -d, --database    Database name.                               [string] [required]
  -u, --user        Username for database.                       [string] [required]
  -x, --pass        Password for database.                       [string] [required]
  -p, --port        Port number for database. Ex: 3306                    [number]
  -o, --output      What directory to place the models.                 [string]
  -t, --tables      table name to import                         [string] [required]
  -f, --over-write  Force to overwrite existed model files                [boolean]

设置

package.json [选项 1]

"scripts": {
  "model": "mysql-sequelize-auto -h 127.0.0.1 -d database_name -p 3306 -u user -x password -o './app/model' -t table_name"
}

命令行

npm run model

package.json [选项 2]

"scripts": {
  "model": "mysql-sequelize-auto -h 127.0.0.1 -d database_name -p 3306 -u user -x password -o './app/model'"
}

命令行

npm run model -- --t=table_name

例子

生成[test_table]的sql脚本

CREATE TABLE `test_table` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `key` VARCHAR(30) NOT NULL COMMENT 'Article key',
  `title` VARCHAR(100) NOT NULL COMMENT 'Article title',
  `content` TEXT NOT NULL COMMENT 'Article content',
  `created_time` DATETIME NOT NULL COMMENT 'Created time',
  `updated_time` DATETIME NOT NULL COMMENT 'Updated time',
  `removed` TINYINT(1) NOT NULL DEFAULT 0 COMMENT 'Flag of soft deletion',
  PRIMARY KEY (`id`));

生成的Model文件

/model/TestTable.ts

import { Application } from 'egg';
import { TestTable } from './define/TestTable';

export default function(app: Application) {
  const { DataTypes } = app.Sequelize;

  const ExportModel = app.model.define<TestTable, any>('TestTable', 
    {
	id: {
		autoIncrement: true,
		primaryKey: true,
		allowNull: false,
		type: DataTypes.INTEGER,
		comment: ""
	},
	key: {
		allowNull: false,
		type: DataTypes.STRING(30),
		comment: "Article key"
	},
	title: {
		allowNull: false,
		type: DataTypes.STRING(100),
		comment: "Article title"
	},
	content: {
		allowNull: false,
		type: DataTypes.TEXT,
		comment: "Article content"
	},
	created_time: {
		allowNull: false,
		type: DataTypes.DATE,
		comment: "Created time"
	},
	updated_time: {
		allowNull: false,
		type: DataTypes.DATE,
		comment: "Updated time"
	},
	removed: {
		allowNull: false,
		type: DataTypes.TINYINT,
		defaultValue: 0,
		comment: "Flag of soft deletion"
	}
}
  , {
    timestamps: false, // 去除createAt updateAt
    freezeTableName: true, // 使用自定义表名
    tableName: 'test_table',
  });

  return ExportModel;

}

/model/define/TestTable.d.ts

import { Model, CreationAttributes } from 'sequelize';

interface TestTableAttributes
  {
	id?: number;
	key?: string;
	title?: string;
	content?: string;
	created_time?: Date;
	updated_time?: Date;
	removed?: number
}
  
class TestTable extends Model<TestTableAttributes, CreationAttributes> implements TestTableAttributes 
  {
	id?: number;
	key?: string;
	title?: string;
	content?: string;
	created_time?: Date;
	updated_time?: Date;
	removed?: number
}
  
export { TestTableAttributes, TestTable };
