railsのenum型で沼

class Task < ApplicationRecord
  validates :task_name, presence: true, length: { maximum: 190 }
  validates :detail, length: { maximum: 190 }
  validates :priority, presence: true, numericality: { only_integer: true }
  validates :status, presence: true, numericality: { only_integer: true }

  enum priority: {
    '低': 0,
    '標準': 1,
    '高': 2
  }

  enum status: {
    '未着手': 0,
    '着手中': 1,
    '完了': 2
  }

  create_table "tasks", charset: "utf8mb4", force: :cascade do |t|
    t.string "task_name", null: false
    t.datetime "date_limit"
    t.integer "priority", default: 1
    t.integer "status", default: 0
