Rails 4、Rspec 和 Factory Girl：URI::InvalidURIError（多租户）

Question

我正在学习有关 Rails 4 和多租户的教程，但在尝试测试用户是否可以作为所有者登录并重定向到创建的子域时出现错误。

这是测试错误：

Failures:

  1) User sign in signs in as an account owner successfully
     Failure/Error: visit root_url

     URI::InvalidURIError:
       bad URI(is not URI?): http://#{account.subdomain}.example.com
     # /Users/developer/.rvm/gems/ruby-2.3.1/gems/capybara-2.10.1/lib/capybara/rack_test/browser.rb:71:in `reset_host!'
     # /Users/developer/.rvm/gems/ruby-2.3.1/gems/capybara-2.10.1/lib/capybara/rack_test/browser.rb:21:in `visit'

Finished in 0.56981 seconds (files took 1.26 seconds to load)
11 examples, 1 failure, 6 pending

这是测试：

require "rails_helper"

feature "User sign in" do
  extend SubdomainHelpers

  let!(:account) { FactoryGirl.create(:account) }
  let(:sign_in_url) {"http://#{account.subdomain}.example.com/sign_in"}
  let(:root_url) {"http://#{account.subdomain}.example.com/"}

   within_account_subdomain do
     scenario "signs in as an account owner successfully" do
       visit root_url
       expect(page.current_url).to eq(sign_in_url)
       fill_in "Email", :with => account.owner.email
       fill_in "Password", :with => "password"
       click_button "Sign in"
       expect(page).to have_content("You are now signed in.")
       expect(page.current_url).to eq(root_url)
     end
   end
 end

这里是工厂：

帐号：

FactoryGirl.define do
  factory :account, :class => Subscribe::Account do
    sequence(:name) { |n| "Test Account ##{n}" }
    sequence(:subdomain) { |n| "test#{n}" }
    association :owner, :factory => :user
  end
end

用户：

FactoryGirl.define do
  factory :user, :class => Subscribe::User do
    sequence(:email) { |n| "test#{n}@example.com" }
    password "password"
    password_confirmation "password"
  end
end

我真的不熟悉BDD，如果您需要我进一步发布任何内容，请告诉我。

Answer 1

所以我解决了这个问题：

问题出在我的 SubdomainHelpers 文件中

module SubdomainHelpers
  def within_account_subdomain
    ### This Line Is the original line
    let(:subdomain_url) { 'http://#{account.subdomain}.example.com' }

    ### Changed it to this
    let(:subdomain_url) { "http://#{account.subdomain}.example.com" }

    before { Capybara.default_host = subdomain_url }
    after { Capybara.default_host = 'http://www.example.com' }
    yield
  end
end

由于某种原因，使用单引号将account.subdomain 保留为字符串；一旦我改为双引号，测试就通过了！

谢谢。
