更新到 Capybara 2.1.0.rc，现在我的功能规范中的 current_path 有问题

Question

看来我在request specs 中多次使用current_path。但是，Capybara 现在要求规格在 features directory 中才能使用 Capybara DSL (page & visit)

# creating_posts_spec.rb

require "spec_helper"

feature "creating posts" do

  scenario "creating posts with valid info is successful" do
    visit new_post_path
    fill_in 'Title', with: "This is a title test"
    fill_in 'Content', with: "This is a content test"
    click_button 'Create Post'
    page.should have_content 'Post was successfully created.'
    page.current_path.should == post_path(post)
  end
end

它是一个简单的帖子控制器，并且在帖子在浏览器中呈现后页面就会显示出来。

 posts GET    /posts(.:format)               posts#index
                     POST   /posts(.:format)               posts#create
            new_post GET    /posts/new(.:format)           posts#new
           edit_post GET    /posts/:id/edit(.:format)      posts#edit
                post GET    /posts/:id(.:format)           posts#show
                     PUT    /posts/:id(.:format)           posts#update
                     DELETE /posts/:id(.:format)           posts#destroy
                root        /                              posts#index

为什么我收到错误消息：undefined local variable or method 'post'？

我只是不记得曾经遇到过这种麻烦。 有人有建议或理由吗？还是我错过了一些明显的东西？来晚了

因为post是未定义....你没有在整个场景中的任何地方设置它。
