레일 : 중첩 모델을 갈퀴와 위조로 채우기

Question

테스트 데이터로 데이터베이스를 채우고 싶습니다. 사용자 및 프로필 모델이 서로 1 대 1 관계로 서로 분리되어 있습니다. 실행중인 스크립트는 데이터를 만들지 만 함께 연결하지는 않습니다. 데이터를 함께 연결하려면 어떻게해야합니까?

응용 프로그램/모델/user.rb

class User < ActiveRecord::Base 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable 
    has_one :profile 

    attr_accessible :email, :password, :password_confirmation, :remember_me,  :profile_attributes 


accepts_nested_attributes_for :profile 

end 

응용 프로그램/모델/profile.rb

class Profile < ActiveRecord::Base 
    belongs_to :user 

    attr_accessible :first_name, :last_name 

    validates :first_name, presence: true 
    validates :last_name, presence: true

    Last_name = Forgery::Name.last_name 
    email = "example-#{n+1}@railstutorial.org" 
    password = "password" 
    User.create!(email: email, 
       password: password, 
       password_confirmation: password) 
    Profile.create!(first_name: first_name, 
        last_name: Last_name) 
    end 
end 
end

user.create_profile을 사용해보세요! 대신에 Profile.create!

namespace :db do 
    desc "Fill database with sample data" 
    task populate: :environment do 
    user = User.create!(email: "dufall@iinet.net.au", 
      password: "123qwe", 
      password_confirmation: "123qwe") 
    user.create_profile!(first_name: "Aaron", 
       last_name: "Dufall") 
    99.times do |n| 
    first_name = Forgery::Name.first_name 
    Last_name = Forgery::Name.last_name 
    email = "example-#{n+1}@railstutorial.org" 
    password = "password" 
    user = User.create!(email: email, 
       password: password, 
       password_confirmation: password) 
    user.create_profile!(first_name: first_name, 
        last_name: Last_name) 
    end 
end 
end
