Midway plugin for Sequelize V7
npm i @ckpack/midway-plugin-sequelize @sequelize/core --save
import { join } from 'node:path';
import { Configuration, ILifeCycle } from '@midwayjs/core';
import * as sequelize from '@midwayjs/sequelize';
@Configuration({
imports: [
// ...
sequelize,
],
importConfigs: [join(__dirname, './config')],
})
export class MainConfiguration implements ILifeCycle {
// ...
}
详细参考https://sequelize.org/docs/v7/models/defining-models/
import { DataTypes, InferAttributes, InferCreationAttributes, Model } from '@sequelize/core';
import { Attribute, NotNull } from '@sequelize/core/decorators-legacy';
class User extends Model<InferAttributes<User>, InferCreationAttributes<User>> {
@Attribute(DataTypes.STRING)
@NotNull
declare firstName: string;
@Attribute(DataTypes.STRING)
declare lastName: string | null;
}
import { Person } from '../entity/person';
export default {
// ...
sequelize: {
dataSource: {
// 第一个数据源,数据源的名字可以完全自定义, 具体参数与new Sequelize()构造函数参数一致
default: {
dialect: 'postgres',
database: 'test4',
username: 'root',
models: [Person], // 注意此处与@midwayjs/sequelize不同
},
// 第二个数据源
default2: {
// ...
},
},
},
};
详细参考https://sequelize.org/docs/v7/category/querying/
import { Provide } from '@midwayjs/core';
import { Person } from '../entity/person';
@Provide()
export class PersonService {
async createPerson() {
const person = new Person({ name: 'bob', age: 99 });
await person.save();
}
}
数据源即创建出的 sequelize 对象,我们可以通过注入内置的数据源管理器来获取。
import { InjectDataSource } from '@ckpack/midway-plugin-sequelize';
import { Sequelize } from '@sequelize/core';
import { Person } from '../entity/person';
export class UserService {
// 注入默认数据源
@InjectDataSource()
defaultDataSource: Sequelize;
// 注入自定义数据源
@InjectDataSource('default2')
customDataSource: Sequelize;
async getUser() {
console.log(await this.defaultDataSource.models.Person.findAll());
}
}
