黄瓜特征显示错误"No Route Matches"

Question

我有一个类似的功能文件

Feature: search for movies by director
As a movie buff
So that I can find movies with my favorite director
I want to include and serach on director information in movies I enter
Background: movies in database
Given the following movies exist:
| title        | rating | director     | release_date |
| Star Wars    | PG     | George Lucas |   1977-05-25 |
| Blade Runner | PG     | Ridley Scott |   1982-06-25 |
| Alien        | R      |              |   1979-05-25 |
| THX-1138     | R      | George Lucas |   1971-03-11 |
Scenario: add director to existing movie
When I go to the edit page for "Alien"
And  I fill in "Director" with "Ridley Scott"
And  I press "Update Movie Info"
Then the director of "Alien" should be "Ridley Scott"

现在我有一个这样的步骤定义，它通过了给定以下电影的存在：案例。

Given /the following movies exist/ do |movies_table|
  movies_table.hashes.each do |movie|
  Movie.create!(movie)
end

结束

但当黄瓜运行步骤时，当我转到"外星人"的编辑页面时，它会抛出这个错误

没有路由匹配｛：action=>"编辑"，：controller=>"电影"｝
（ActionController:：RoutingError）./features/support/paths.rb:20:在"path_to"中

我的paths.rb在path_to 中有这个案例

when /^the edit page for (.*)/
  m = Movie.find_by_title($1)
  edit_movie_path(m)

我检查过m是零，但在后台我把其中四部电影添加到了数据库中。我还检查了"确定路线"，但所有路线都存在。

请帮我理解，我对铁轨和黄瓜很陌生。感谢

Answer 1

(.*)周围缺少双引号

when /^the edit page for (.*)/

应该是

when /^the edit page for "(.*)"/

解释：假设您的websteps.rb包含

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

这意味着它将首先通过调用path_to('the edit page for "Alien"')来获取url。因此，您提交path_to函数的情况应该只提取名称Alien。由于缺少双引号，$1包含"Alien"，而不是仅包含Alien。find_by_title实际上正在寻找一部低于的电影

m = Movie.find_by_title('"Alien"') # Doesn't exist for sure ;)
