为用户创建多个工厂

Question

之前我为用户提供了一个工厂，它工作得很好。

但是现在，我想要两组用户数据工厂，一组带有加密详细信息，另一组带有纯文本用户详细信息。

这是我正在使用的代码：

FactoryBot.define do
  factory :user do
   trait :encryption do 
    email                 AESCrypt.encrypt(Faker::Internet.email, ENV["AES_KEY"])
    password              AESCrypt.encrypt("password", ENV["AES_KEY"])
    password_confirmation AESCrypt.encrypt("password",ENV["AES_KEY"])
    username              Faker::Name.name 
    end

   trait :unencrypted_user_details do
    email                 Faker::Internet.email
    password              "password"
    password_confirmation "password"
    username              Faker::Name.name 
   end
 end
end

并使用与规范文件中相同的内容：

user = FactoryBot.create(:user,:unencrypted_user_details)

但运行规范时出现以下错误：

NoMethodError:
   undefined method `name=' for #<User:0x00000006d512f8>

用户模型没有字段“名称”，而是存在“用户名”。

错误堆栈跟踪：

user_spec.rb

 describe "Generate Pin API" do
  it "generates a new pin for the user" do
    user = FactoryBot.create(:unencrypted_user_details)  #line 43

    client = user.client

    request.env["HTTP_AUTHORIZATION"] = user.auth_token

    get :generate_pin

    response_json = JSON.parse(response.body)

    expect(response_json["response_code"]).to eq(200)
  end
end

控制器代码

def generate_pin
phone = ValidatePhone.find_by(phone_no: @client.phone_no)

phone.present? ? phone.update_attributes(is_verified: true) : ValidatePhone.create(phone_no: @client.phone_no)
sms_text = "Hello"
send_sms(@client.phone_no,sms_text)
render :json => {
        :response_code => 200,
        :response_message => "Welcome Onboard."
    }

结束

这是创建多个工厂的正确方法吗？为什么我会收到此错误未定义的方法名称？

Answer 1

这不是创建变量工厂的方法。您必须对值为调用结果的字段使用方括号：

FactoryBot.define do
  factory :user do
   trait :encryption do 
    email    { AESCrypt.encrypt(Faker::Internet.email, ENV["AES_KEY"]) }
    password { AESCrypt.encrypt("password", ENV["AES_KEY"]) }
    password_confirmation { AESCrypt.encrypt("password",ENV["AES_KEY"]) }
    username { Faker::Name.name }
  end

  trait :unencrypted_user_details do
    email                 { Faker::Internet.email }
    password              "password"
    password_confirmation "password"
    username              { Faker::Name.name }
   end
 end
end
