黄瓜奇怪的路线问题

Question

我在 Rails 中做一个简单的应用程序而不使用黄瓜

我有这个用户故事：

Scenario: add new expense
  Given I am on the expenses page
  When I follow "new expense"
  Then I am on new expense page
  Then I fill in "expense_title" with "french fries"
  Then I fill in "expense_category" with "Lunch"
  Then I fill in "expense_amount" with "2300"
  And I press "expense_submit" 
  And I should be on the "french fries" expense page
  Then I should see "The expense was successfully created"

在开发模式下，我按照相同的步骤操作，得到了预期的结果，但是用 cucumber 运行它会收到此错误消息

(::) failed steps (::)

expected: "/expenses/2",
     got: "/expenses" (using ==) (RSpec::Expectations::ExpectationNotMetError)
./features/step_definitions/web_steps.rb:260:in `/^(?:|I )should be on (.+)$/'
features/expenses.feature:14:in `And I should be on the "french fries" expense page'

我已经在path.rb中设置了正确的路径

when /the "(.+)" expense page/
      "/expenses/#{Expense.find_by_title($1).id}"

正因为如此，前面代码的结果对应的预期路径是对的，但得到的结果却不是。

当我在提交按钮后添加“然后显示页面”时，我会得到一个带有以下消息的简单页面：

You are being redirected.

但是正如我之前所说，这在开发模式下不会发生，并且我已经检查过记录是否已成功存储到数据库中，所以我不知道问题出在哪里，有没有人可以帮助我?

问候

PS：我的创建方法

respond_to :html

def create
    @expense = Expense.new(params[:expense])

    if @expense.save
      flash[:notice] = "The expense was successfully created"
    end

    respond_with @expense
  end

Answer 1

问题是 webrat 与 rails 3 的兼容性问题，

和this一样的问题，有解决办法，给webrat gem打个简单的补丁

Answer 2

在我看来，您的 paths.rb 配置正确，但您的 create 操作正在重定向回 expenses_path。
