FactoryGirl + Faker - 为db种子数据中的每个对象生成相同的数据

问题描述

我使用FactoryGirl和Faker在我的 seeds.rb 文件中生成用户对象，但由于某种原因，正在创建完全相同的用户，

用户的工厂：

$ b b

 ＃users.rb 
要求'faker'
 
 FactoryGirl.define do 
 factory：user do 
 first_name Faker :: Name.first_name 
 last_name Faker :: Name.last_name 
 phone Faker :: PhoneNumber.cell_phone 
 email Faker :: Internet.email 
 passwordpassword
 password_confirmationpassword
 end 
 end 
  

c $ c> seeds.rb 档案：

 ＃seeds.rb 
 rand 5..11）.times {FactoryGirl.create（：user）} 
  

错误：

ActiveRecord :: RecordInvalid：验证失败：已发送电子邮件

如果我打开控制台并使用 FactoryGirl.create（：user）我得到相同的结果...相同的对象被创建一遍又一遍，即使如果我运行 Faker :: Internet.email 几次我会收到几封电子邮件。

FactoryGirl： / p>

  [1] pry（main）> FactoryGirl.create（：user）
 ... 
 => ＃< User id：3，first_name：Osvaldo，last_name：Wunsch，email：[email protected]，phone：[phone] x64848，created_at：2014-07-31 20:57:27，updated_at：2014-07-31 20:57:27，encrypted_pa​​ssword：$ 2a $ 10 $ mxWC7yLYR0m / Sw8MO6Lyru.xuTHCdCEuM9Orx3LXGApF ...，reset_password_token：nil，reset_password_sent_at：nil，remember_created_at：nil ，sign_in_count：0，current_sign_in_at：nil，last_sign_in_at：nil，current_sign_in_ip：nil，last_sign_in_ip：nil> 
 [2] pry（main）> FactoryGirl.create（：user）
 ... 
 ActiveRecord :: RecordInvalid：验证失败：电子邮件已被采取
  

Faker本身：

  [3] Faker :: Internet.email 
 => [email protected]
 [4] pry（main）> Faker :: Internet.email 
 => [email protected]
  

我在这里缺少什么？为什么Faker每次通过FactoryGirl使用时都会生成相同的数据？

解决方案

  Faker :: Internet.email 
  

试试...

 电子邮件{Faker :: Internet.email} 
  

I am using FactoryGirl and Faker to generate user objects in my seeds.rb file but for some reason the exact same user is being created and rake db:seed is failing because of an email uniqueness validation.

Factory for users:

#users.rb
require 'faker'

FactoryGirl.define do
  factory :user do
    first_name            Faker::Name.first_name
    last_name             Faker::Name.last_name
    phone                 Faker::PhoneNumber.cell_phone
    email                 Faker::Internet.email
    password              "password"
    password_confirmation "password"
  end
end

And the code in seeds.rb file:

#seeds.rb
rand(5..11).times { FactoryGirl.create(:user) }

Error:

ActiveRecord::RecordInvalid: Validation failed: Email has already been taken

If I open the console and use FactoryGirl.create(:user) I get the same results...same object is being created over and over even though if I run just Faker::Internet.email several times I'll get several e-mails.

FactoryGirl:

[1] pry(main)> FactoryGirl.create(:user)
...
=> #<User id: 3, first_name: "Osvaldo", last_name: "Wunsch", email: "[email protected]", phone: "[phone] x64848", created_at: "2014-07-31 20:57:27", updated_at: "2014-07-31 20:57:27", encrypted_password: "$2a$10$mxWC7yLYR0m/Sw8MO6Lyru.xuTHCdCEuM9Orx3LXGApF...", reset_password_token: nil, reset_password_sent_at: nil, remember_created_at: nil, sign_in_count: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil>
[2] pry(main)> FactoryGirl.create(:user)
...
ActiveRecord::RecordInvalid: Validation failed: Email has already been taken

Faker by itself:

[3] pry(main)> Faker::Internet.email
=> "[email protected]"
[4] pry(main)> Faker::Internet.email
=> "[email protected]"

What am I missing here? Why is Faker producing the same data every time when used through FactoryGirl?

解决方案

You need to pass a block if you want the values re-evaluated for each instance created.

Instead of

email   Faker::Internet.email

try...

email   { Faker::Internet.email }
