使用Devise保存has_one模型與嵌套窗體 - Rails 4

我被困在Rails項目中，當用戶註冊Devise時試圖保存has_one模型。使用Devise保存has_one模型與嵌套窗體 - Rails 4

我的應用程序正在保存子模型以及新用戶，但問題是它不保存用戶表中的子ID。

我試過很多在Stackoverflow上找不到的選項。我做錯了什麼？

用戶模型：

class User < ActiveRecord::Base 
    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable, :omniauthable, :omniauth_providers => [:linkedin] 

    # Associations 
    has_one :build, inverse_of: :user 
    # Allow saving of attributes on associated records through the parent, 
# :autosave option is automatically enabled on every association 
    accepts_nested_attributes_for :build, allow_destroy: true 
end

構建模型

class Build < ActiveRecord::Base 
    belongs_to :user, inverse_of: :build 
    has_one :template 
    # validates_presence_of :user 
end

註冊記憶控制器

class Users::RegistrationsController < Devise::RegistrationsController 
before_action :sign_up_params, only: [:create] 
before_action :account_update_params, only: [:update] 
# before_filter :configure_permitted_parameters 

    # GET /resource/sign_up 
    def new

    build_resource({})

    # @build = @user.builds.build(template_id: params[:template_id], domain_url: params[:domain_url]) 
    end 

    # POST /resource 
    def create 
    super 
    # @build = current_user.build.build(params[:post]) 

    # @build = @user.build.build(template_id: sign_up_params[:template_id], domain_url: sign_up_params[:domain_url])

的問題是，用戶先保存，然後你的關係目的，你可以節省USER_ID保存構建構建而不是保存build_id用戶

感謝。可能就是這樣。有關我如何一次拯救它的任何想法？ – apwn

你正在保持你真實的模型懸念，並問你需要共享所有三個模型的答案，你想明確實現什麼。然後我可能會幫忙。 –

params.require(:user).permit(:first_name, :last_name, :email, :password, :password_confirmation, build_attributes: [:id, :template_id, :domain_url])

build_attributes應表有:id

使得測試

def create 
    user = User.new(sign_up_params) 
    user.save 
end

謝謝佈雷諾。但是，它不起作用，因爲它沒有從表單中獲取id。我認爲它首先保存了用戶，並沒有構建ID。 '參數：{ 「UTF8」=> 「✓」，「authenticity_token」=> 「Atu7B4voCs8T1Rtz82zc3MRABSUfqQa9374ogg1WVBL5W0Kicc9DLrigggOuVJL + rb0FXjHJ5Yu5Bvfo05 + NXA ==」，「用戶」=> { 「first_name的」=> 「ophk」，「姓氏」=> 「kddkd」，「email」=>「[email protected]」，「password」=>「[FILTERED]」，「password_confirmation」=>「[FILTERED]」，「build_attributes」=> {「template_id」=> 「1」，「domain_url」=>「khljgjjff.com」}}，「commit」=>「註冊」}' – apwn

但是插入一個binding.pry或調試以驗證用戶。錯誤'來識別已建立的對象構建或有錯誤 –

使用binding.pry是個好主意，但是問題已經解決了。問題是用戶先保存然後編譯，但他希望在用戶表中創建id。這是不可能的。 –

模型User.rb

has_one :build 
accepts_nested_attributes_for :build, allow_destroy: true

軌控制檯

user = User.new(name: 'example', build_attributes:{template_id:1, domain_url: 'test'}) 

user.save # this will create user and after that will create has_one build association 
user.errors unless user.save
