Модель:
class Reservation < ApplicationRecord
# https://naturaily.com/blog/ruby-on-rails-enum
enum recurrence: {
daily: 0,
weekly: 1,
monthly: 2,
annually: 3
}, _prefix: :recurring
belongs_to :user
validates :name, :user_id, presence: true
...
end
Миграция:
class CreateReservations < ActiveRecord::Migration[5.2]
def change
create_table :reservations do |t|
t.string 'name', null: false
...
t.boolean 'recurring', default: false, null: false
t.integer 'recurrence', index: true, allow_blank: true, default: nil # trying a lot of things here
t.datetime 'expire_time'
...
end
end
end
Работает, как и ожидалось, в консоли:
2.4.5 :002 > res = Reservation.new(name: 'test', user_id: 1)
=> #<Reservation id: nil, name: "test", recurring: false, recurrence: nil, date: nil, start_time: nil, end_time: nil, expire_time: nil, user_id: 1, created_at: nil, updated_at: nil>
2.4.5 :003 > res.valid?
User Load (0.7ms) SELECT "users".* FROM "users" WHERE "users"."deleted_at" IS NULL AND "users"."id" = $1 LIMIT $2 [["id", 1], ["LIMIT", 1]]

И все же в Rails Admin, когда ясоздайте или отредактируйте запись, все они будут назначены первому перечислению.Даже когда я намеренно удаляю значение из формы, он все равно сохраняет запись с первым значением перечисления.
Rails Admin:
config.model Reservation do
weight 2
parent Event
list do
field :name
field :display_date do
formatted_value { bindings[:object].display_date }
end
field :recurrence, :active_record_enum # should be unnecessary, but trying everything
field :expire_time
field :user do
label 'Creator'
formatted_value { bindings[:object].user.name }
end
end
end
Я пытался:
- не индексирует это поле (думая, что администратору Rails нужно значение для индексированных столбцов)
- обеспечение того, что `: active_record_enum` объявлено в` field: recurrence`
Как и предполагалось, вот соответствующий раздел журнала:

И, конечно же, параметр "recurrence"=>"" преобразуется в ["recurrence", 0]
Кажется, это известная проблема , но если это законноошибка, мне все еще нужна помощь с обходным путем.Кто-нибудь уже решил это?
