Question

我有一个check_in（保留）表单，在某些时候我想要一个嵌套表单来添加room_requests：

= nested_form_for @reservation, url: check_in_check_in_path, method: 'put' do |f|
  = f.fields_for :guests do |guest_form|
    = label_tag t('users.new.first_name'), nil,  class: 'grey h2 input-label'
    = guest_form.text_field(:first_name, class: 'check-in-input')
    (...)
  = f.link_to_add "Add guest", :guests

  = f.fields_for :room_requests do |room_form|
    = label_tag nil, t('rooms.new.category'), class: 'grey h2'
    = room_form.select(:room_category_id, current_hotel.room_categories.collect {|p| [ p.category, p.id, rate: p.base_rate ] }, {}, class: 'dropdown form-input category-dropdown')
  (...)
  = f.link_to_add "Add room request", :room_requests

从上面的代码中，＆＃34;添加访客＆＃34;按钮工作，但＆＃34;添加房间请求＆＃34;没有。

来自预订模式：

class Reservation < ActiveRecord::Base
  has_many :guests
  accepts_nested_attributes_for :guests, allow_destroy: false
  has_many :room_requests, dependent: :destroy, inverse_of: :reservation
  accepts_nested_attributes_for :room_requests, allow_destroy: true
end

并且reservation_controller.rb：

class ReservationsController < ApplicationController
  def reservation_params
    params.require(:reservation).permit(
    :start_date, :end_date, :status, :tag_list, :sales_channel_id,
    :comments, :room_category_id, :client_id,
    client_attributes: [:id, :hotel_id, :first_name, :last_name, :address, :country,
                        :doc_type, :doc_number, :email, :phone, :city],
    room_requests_attributes: [:id, :adults, :children, :room_category_id, :hotel_id,
                               :price,  :rate_id, :room_id, :_destroy],
    guests_attributes: [:id, :first_name, :last_name, :nationality, :room_request_id,
                        :doc_type, :doc_number])
  end
end

我错过了什么？

Answer 1

乍一看，对于嘉宾来说，似乎有：

= f.link_to_add "Add guest", :guest

但是对于room_requests，你有：

= f.link_to_add "Add room request", :room_requests

尝试制作：room_requests singular =＆gt; ：room_request

关联无效。确保使用accepts_nested_attributes_for
