我正在使用webrat和cucumber（rails 3）开发一些项目，所以我用这个命令创建了一个功能
rails g cucumber:feature Requeriment client:string realization:date hour:string shipping_company:string booking:string destiny:string rtype:string
然后我的功能就像这样
Scenario: Delete requeriment
Given the following requeriments:
|client|realization|hour|shipping_company|booking|destiny|rtype|
|client 1|20/01/2011|08:30|shipping_company 1|booking 1|destiny 1|rtype 1|
|client 2|20/01/2011|08:30|shipping_company 2|booking 2|destiny 2|rtype 2|
|client 3|20/01/2011|08:30|shipping_company 3|booking 3|destiny 3|rtype 3|
|client 4|20/01/2011|08:30|shipping_company 4|booking 4|destiny 4|rtype 4|
When I delete the 3rd requeriment
Then I should see "La orden de servicio fue eliminada exitosamente"
And I should see the following requeriments:
|Client|Realization|Hour|Shipping company|Booking|Destiny|Rtype|
|client 1|20/01/2011|08:30|shipping_company 1|booking 1|destiny 1|rtype 1|
|client 2|20/01/2011|08:30|shipping_company 2|booking 2|destiny 2|rtype 2|
|client 4|20/01/2011|08:30|shipping_company 4|booking 4|destiny 4|rtype 4|
当我运行它时，我收到此错误消息
Using the default profile...

cucumber features/manage_requeriments.feature:27 # Scenario: Delete requeriment
2 scenarios (1 failed, 1 passed)
23 steps (1 failed, 2 skipped, 20 passed)
0m1.263s
但我没有定义任何类型的方法，我不知道为什么webrat正在试图称之为
我的步骤定义在这里
When /^I delete the (\d+)(?:st|nd|rd|th) requeriment$/ do |pos|
visit requeriments_path
within("table tr:nth-child(#{pos.to_i+1})") do
click_link "Destroy"
end
end
任何人都可以帮助我吗？
答案 0 :(得分：1)
./ app / views / requeriments / show.html.erb第10行是错误所在的位置。你有单表继承吗？这就是它的味道。
