ruby-on-rails - Capybara 找不到表单元素

Question

这是我第一次尝试 Capybara，我似乎无法找到为什么它找不到我的表单元素。

每次我尝试查找表单元素时，

When /^they submit a resolution in Markdown$/ do
  visit "/resolutions/new"
  fill_in "title", :with => "Title"
  fill_in "libelle", :with => "Some text here\n\nNew paragraph"
  click_button "Submit"
end

它不知道它在哪里，

Scenario: Submission of a resolution                 # features/resolutions.feature:5
    Given the user is a member                       # features/step_definitions/user_steps.rb:26
    When they submit a resolution in Markdown        # features/step_definitions/resolution_steps.rb:8
      cannot fill in, no text field, text area or password field with id, name, or label 'title' found (Capybara::ElementNotFound)
      (eval):2:in `fill_in'
      ./features/step_definitions/resolution_steps.rb:10:in `/^they submit a resolution in Markdown$/'
      features/resolutions.feature:7:in `When they submit a resolution in Markdown'

即使它出现在页面上

<%= form_for(@resolution) do |f| %>
  <div class="field">
    <%= f.label :title %><br />
    <%= f.text_field :title %>
  </div>
  <div class="field">
    <%= f.label :libelle %><br />
    <%= f.text_area :libelle %>
  </div>
  <div class="actions">
    <%= f.submit "Submit" %>
  </div>
<% end %>

它似乎已经正确渲染了。

这似乎很明显，但我找不到。我找到了this question ，但答案毫无用处。即使在查看 the Devise+Cucumber example app 之后，我找不到问题所在。

这正在杀死我和我的测试。有什么想法吗？

尝试在 visit "/resolutions/new" 之后添加 puts page.body 并查看堆栈跟踪告诉您什么。您将能够看到表单字段的 id。例如，虽然我的一列名为“name”，但呈现的 html 中的 id 是“user_name”。
