黄瓜步骤定义找不到类

Question

我有一个黄瓜步骤定义，它没有在对象上拾取。

错误是：

   | title       | description            |
      | First Issue | This is a first issue. |
      undefined method `issues' for nil:NilClass (NoMethodError)
      ./features/step_definitions/issue_steps.rb:3:in `block (2 levels) in <top (required)>'

特点：

Background:    
    Given there is a release called "First Release"
    And that release has a feature:
      | title                | description   |
      | Make it shiny!       | Gradients! Starbursts! Oh my! |
    And that feature has a issue:
      | title                | description   |
      | First Issue          | This is a first issue. |
    And I am on the homepage

路线：

resources :releases do 
      resources :features
 end

 resources :features do 
      resources :issues
 end

步骤定义：

Given /^that feature has a issue:$/ do |table|
  table.hashes.each do |attributes|
    @feature.issues.create!(attributes)
  end
end

步骤定义：特征

Given /^that release has a feature:$/ do |table|
  table.hashes.each do |attributes|
    @release.features.create!(attributes)
  end
end

Answer 1

你在哪里定义@feature？

错误信息显示该步骤正在调用@feature.issues，但@feature 为nil，这意味着无法获取问题。
