Açaí's Framework model

模型是一种使用格式化、保存和其他 crud 操作的方法对数据进行分组的简单方法。

Usage

Declare model

import Model from "@acai/model";

@Model.Table("user", "connection2")
export class User extends Model {
  @Model.Field()
  public id: string;

  @Model.Field()
  public name: string;

  @Model.Field()
  public email: string;

  @Model.Field()
  public avatar?: string;
}

CRUD operations

// get
const user = await User.find("id");
const user2 = await User.query().where("name", "John").first();

// create/update
const user = new User();
await user.save();

// delete
const user = await User.find("id");
await user.delete();

Extending types

Types parts

• onCreate When setting a field value into the model
• onSave From model to database
• onRetrieve From database to model
• onSerialize From model to JS object
