Недопустимые параметры с вложенными атрибутами вложенных атрибутов

Question

У меня есть три модели, одна вложена в другую.

Модель магазина

class Shop < ApplicationRecord
  has_many :opening_days, dependent: :destroy
  accepts_nested_attributes_for :opening_days, allow_destroy: true
end

Модель открытия дня

class OpeningDay < ApplicationRecord
  belongs_to :shop, optional: true
  has_many :opened_intervals, dependent: :destroy
  accepts_nested_attributes_for :opened_intervals, allow_destroy: true
end

И модель открытия_интервала

class OpenedInterval < ApplicationRecord
  belongs_to :opening_day, optional: true
end

У меня есть simple_form с вложенными атрибутами:

<%= simple_form_for @shop do |f| %>
    <p>opening days</p>
    <div class="opening-days-fields">
      <% i = 0 %>
      <%= f.simple_fields_for :opening_days do |builder_opening_day| %>
        <%= render 'shops/opening_day_fields', builder_opening_day: builder_opening_day, i: i %>
        <% i = i + 1 %>
      <% end %>
    </div>

    <%= f.submit "Update shop", class: "btn-blue-whole-screen" %>
  <% end %>

Партиал с открытием_day_fields.rb

<div class="opening-day">
  <div class="day">
    <%= builder_opening_day.input :day %>
  </div>
  <div class="full-day">
    <%= builder_opening_day.input :full_day %>
  </div>
</div>

<div class="fields">
  <%= builder_opening_day.simple_fields_for :opened_intervals do |builder_opened_interval| %>
    <%= render 'shops/opened_interval_fields', o: builder_opened_interval %>
  <% end %>
  <%= link_to_add_row('Add opened interval', builder_opening_day, :opened_intervals, i, class: 'btn btn-primary') %>
</div>

И второй партиал с открытием_interval_fields.rb

<div class="opened-interval">
  <div class="start">
    <%= o.input :start %>
  </div>
  <div class="end">
    <%= o.input :end %>
  </div>
</div>

В контроллере я разрешаю вложенные атрибуты:

def shop_params
    params.require(:shop).permit(:commercial_name, :legal_name, :company_number, :address, :photo, :photo_cache, :latitude, :longitude, :trading_name, :city, :postcode, :phone, opening_days_attributes: [:id, :day, :full_day], opened_intervals_attributes: [:id, :start, :end])
  end

Но Rails их не принимает:

Вот как выглядят параметры:
