Question

尝试提交嵌套的rails表单时，我收到了'NoMethodError'。表单用于创建预留，以及serviceType - 预留（连接模型）。

我得到的错误是＃“

的”未定义方法`属性'

这是我的预订模式：reservation.rb

module Booking
 class Reservation < ActiveRecord::Base
  has_many :service_type_reservations, inverse_of: :reservation, dependent: :destroy
  accepts_nested_attributes_for :service_type_reservations, allow_destroy: true

  has_many :service_types, through: :service_type_reservations, dependent: :destroy
  has_one :customer_reservation, dependent: :destroy
  has_one :customer, through: :customer_reservation, dependent: :destroy

  validates_uniqueness_of :service_type_reservations
 end
end

这是servicetype-reservation模型：servicetypereservation.rb

module Booking
 class ServiceTypeReservation < ActiveRecord::Base
  belongs_to :service_type
  belongs_to :reservation
  belongs_to :service_calendar

  validates :reservation, presence: true
  validates :service_type, presence: true
 end
end

在我的预约控制器中，这些是新的和创建函数：reservations_controller.rb

# GET /reservations/new
def new
  @serviceTypes = ServiceType.all
  @reservation = Reservation.new
  @reservation.build_service_type_reservations
  @numberOfServices = @serviceTypes.length
  if params[:service_type_id]
    @selectedService = ServiceType.find(params[:service_type_id])
  end
end

# POST /reservations
def create
  @serviceTypes = ServiceType.all
  @reservation = Reservation.new(reservation_params)

  if @reservation.save
    redirect_to new_customer_path(reservation_id: @reservation.id), notice: 'Reservation was successfully created.'
  else
    render :new
  end
end

这是预订控制器中的预订参数：

# Only allow a trusted parameter "white list" through.
  def reservation_params
    respond_to do |format|
      format.html { params.require(:reservation).permit(:updated_at, :created_at, :total_price, :customer_id, service_type_reservations_attributes: [:occupancy, :check_in, :check_out, :date, :service_type_id])}
    end
  end

创建嵌套表单：

<%= form_for(@reservation) do |f| %>
   <%= f.fields_for :service_type_reservations do |service_reservation_form| %>

我很确定它正在创建一个新的服务类型保留，但它有一个未定义的ID。我不确定id是否属于该属性。我尝试过更改代码并得到错误“undefined attribute'0'”所以我很确定它是id。

当我创建预订（和servicetype-reservation）时，它是否已自动生成ID？（它通常在铁轨上......）。

任何帮助将不胜感激。谢谢！

我删除了该行

var users = [{
  name: 'talon',
  email: 'talon@test.com',
  password: 'test1234',
  username: 'tdog',
}, {
  name: 'lauren',
  email: 'lauren@test.com',
  password: 'admin1234',
  username: 'ldogg',
}, {
  name: 'cohen',
  email: 'cohen@test.com',
  password: 'baby1234',
  username: 'cdoggy',
}, {
  name: 'kyler',
  email: 'kyler@test.com',
  password: 'delete1234',
  username: 'kdawg'
}];

var len = users.length;
while (len--) {
  if (users[len].email == 'kyler@test.com') {
    users.splice(len, 1);
    break;
  }
}


console.log(users);

来自reservations.rb

现在可以提交表格。没有这条线之前有一个错误，但它突然开始工作。我想我只需要重启服务器。

当提交嵌套表单
