我正在開發一個簡單的軌道應用程序,應該是一個音樂會註冊應用程序。基本上應該做的是從一個人那裏獲取信息,然後將它們保存在DB中也會生成一張帶有唯一ID的票證。問題是表單沒有顯示票據的字段。這些字段顯示的唯一時間是某處出現錯誤時。 enter image description here隱藏字段的未知原因在軌道上嵌套窗體ruby 5

participants_controller 
    def new 
     @participant = Participant.new 
     @ticket = @participant.tickets.build 
     end 

     def create 
     @participant = Participant.new(participant_params) 
     @ticket = @participant.tickets.build 
     1.times{@ticket} 
     if @participant.save 
      flash[:success] = "An Email as been sent to #{@participant.email}" 
      redirect_to root_path 
     else 
      render :new 
     end 
     end 

     private 
     def participant_params 
     params 
      .require(:participant) 
      .permit(:first_name,:last_name,:phone,:email,:gender,:email_confirmation,:participant_id, 
        :tickets_attributes => [:id,:vip,:quantity]) 
     end 

那麼這裏就是形式

= simple_form_for @participant do |f| 
    = f.error_notification 
    = f.input :first_name 
    = f.input :last_name 
    = f.input :phone 
    = f.input :email 
    = f.input :email_confirmation 
    = f.input :gender, collection: ['M','F'], as: :radio_buttons 
    = f.simple_fields_for :tickets do |ticket| 
    = ticket.input :vip , label: 'Want a vip ticket? ',collection: ['No','Yes'] , include_blank: false 
    = ticket.input :quantity , label: 'How many tickets?' , include_blank: false, collection: 1..100 
    = f.button :submit , 'Get Tickets' 

那麼模型

ticket model 
class Ticket < ApplicationRecord 
    belongs_to :participant 
    # validates :quantity, presence: true 
    validates :participant , presence: true 
end 




participant model 
class Participant < ApplicationRecord 

    validates :first_name,:last_name, presence: true 
    VALID_EMAIL_REGEX = /\A[\w+\-.][email protected][a-z\d\-.]+\.[a-z]+\z/i 
    validates :email, presence: true, length: { maximum: 255 }, 
      format: { with: VALID_EMAIL_REGEX }, 
      uniqueness: { case_sensitive: false }, 
      confirmation: true 
    validates :email_confirmation, presence: true 
    VALID_PHONE_NUMBER = /\d/ 
    validates :phone, presence: { message: "Won't give it to NSA promise" }, format:{with: VALID_PHONE_NUMBER}, 
      length: {is: 11} 
    has_many :tickets , inverse_of: :participant 
    accepts_nested_attributes_for :tickets, 
           reject_if: lambda {|attributes| attributes['kind'].blank?} 
end

在創建操作線:

@ticket = @participant.tickets.build 

是什麼增加了日電子票。因此,使用rails嵌套表單,或者甚至在使用simple_form時,您需要使用您想要的記錄數來實例化子關係。所以它會循環遍歷它們並顯示它們。所以,如果你想一票當new動作呈現,只需撥打:

@participant.tickets.build 

在新的動作。

謝謝你解決了一個問題。 現在我意識到沒有任何關於'Ticket'的信息被保存在'db'中。除了id之外,我得到所有'nil'。任何線索? –

參與者正在保存,但票證不是?我看到你把一個reject_if塊包含:'attributes ['kind']。blank?',但我在任何地方都看不到對某種kind屬性的引用。這是你正在使用的東西嗎? – agmcleod

我認爲這是來自互聯網的糟糕的複製粘貼。參與者正在保存並且票據正在保存,但它僅保存創建和更新的次數,但其他屬性未保存。 –
