Rails：使用耙和僞造填充嵌套模型

Question

我想用測試數據填充我的數據庫我的用戶和配置文件模型是以1對1關係彼此分離的形式。我正在運行的腳本會創建數據，但不會將它們關聯在一起。我如何獲得它將數據關聯在一起？

應用程序/模型/ 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 

應用程序/模型/ 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 

末

的lib /任務/ sample_data.rb

namespace :db do 
    desc "Fill database with sample data" 
    task populate: :environment do 
    User.create!(email: "dufall@iinet.net.au", 
      password: "123qwe", 
      password_confirmation: "123qwe") 
    Profile.create!(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.create!(email: email, 
       password: password, 
       password_confirmation: password) 
    Profile.create!(first_name: first_name, 
        last_name: Last_name) 
    end 
end 
end 

Answer 1

嘗試使用user.create_profile！而不是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
