데이터 모델

카테고리 모델 생성하기

node ace make:model Category

# CREATE: app/Models/Category.ts

import { DateTime } from 'luxon'
import { BaseModel, column } from '@ioc:Adonis/Lucid/Orm'

export default class Category extends BaseModel {
  @column({ isPrimary: true })
  public id: number

  @column()
  public name: string

  @column()
  public slug: string

  @column()
  public colorCode: string

  @column.dateTime({ autoCreate: true })
  public createdAt: DateTime

  @column.dateTime({ autoCreate: true, autoUpdate: true })
  public updatedAt: DateTime
}

todos 모델 생성하기

node ace make:model Todo

# CREATE: app/Models/Todo.ts

import { DateTime } from 'luxon'
import { BaseModel, column } from '@ioc:Adonis/Lucid/Orm'

export default class Todo extends BaseModel {
  @column({ isPrimary: true })
  public id: number

  @column()
  public categoryId: number

  @column()
  public title: string

  @column()
  public isCompleted: boolean

  @column.dateTime({ autoCreate: true })
  public createdAt: DateTime

  @column.dateTime({ autoCreate: true, autoUpdate: true })
  public updatedAt: DateTime
}

관계를 맺다

import { BaseModel, column, hasMany, HasMany } from '@ioc:Adonis/Lucid/Orm'
import Todo from 'App/Models/Todo'

export default class Category extends BaseModel {
  // ....

  @hasMany(() => Todo)
  public todos: HasMany<typeof Todo>
}
