Scenario: add color to existing vegetable
  When I go to the edit page for "Potato"
  And I fill in "Color" with "Brown"
  And I press "Update Vegetable Info"
  Then the color of "Potato" should be "Brown"

我目前正在使用“训练轮”,所以我有一个网页步骤(web_steps.rb)：

When /^(?:|I )go to (.+)?/ do |page_name|
  visit path_to(page_name)
end

现在我了解这是如何工作的简单页面导航,如“当我去蔬菜主页.”我所要做的就是添加paths.rb的路径：

When /^the vegetable home page/
  '/vegetables'

但是,通过上面的例子,我需要使用特定的蔬菜“/ vegetables / 1”(Potato url)去特定的路径.

我不知道该怎么做,所以我尝试创建了自己的步骤：

When /I go to the edit page for "(.*)"/ do |vegetable_name|
  flunk "Unimplemented"
end

但我得到错误：

Ambiguous match of "I go to the edit page for "Potato"":

features/step_definitions/vegetable_steps.rb:15:in `/go to the edit page for "(.*)"/'
features/step_definitions/web_steps.rb:48:in `/^(?:|I )go to (.+)$/'

You can run again with --guess to make Cucumber be more smart about it
   (Cucumber::Ambiguous)

这是我应该这样做的吗？或者我只是使用web_steps“转到”步骤并在paths.rb文件中以某种方式提供id？我只想弄清楚如何在阅读各种Cucumber教程后开始这个.
