ruby-on-rails - Nil :NilClass 的 Factory Girl 未定义方法

Question

我有一个类似这样的 Controller 规范

describe :bizzaro_controller do

  let(:credit_card_account) { FactoryGirl.build :credit_card_account }

  it "doesn't blow up with just the stub" do
    CreditCardAccount.stub(:new).and_return(credit_card_account)
  end

  it "doesn't blow up" do
    credit_card_account
    CreditCardAccount.stub(:new).and_return(credit_card_account)
  end

end

结果是:

bizzaro_controller
  doesn't blow up with just the stub (FAILED - 1)
  doesn't blow up

Failures:

  1) bizzaro_controller doesn't blow up
     Failure/Error: let(:credit_card_account) { FactoryGirl.build :credit_card_account }
     NoMethodError:
       undefined method `exp_month=' for nil:NilClass

我的信用卡工厂看起来像这样:

FactoryGirl.define do
  factory :credit_card_account do
    exp_month 10
    exp_year 2075
    number '3'
  end
end

我的 CreditCardAccount 是一个空的 ActiveRecord::Base 模型

=> CreditCardAccount(id: integer, exp_month: integer, exp_year: integer, number: string)

这应该有效。所有点都表明您的测试数据库不正确。

RAILS_ENV=test rake db:drop db:create 将删除并重新创建您的测试数据库。然后尝试使用 rake 命令运行你的 rspec，以迁移数据库:rake rspec
