我觉得我在这里要疯了。对我的 Post 模型进行常规水豚测试。具体来说，确保新页面在有效提交后重定向到新创建的帖子。所以在我的规范/请求文件夹中，我有这个：

describe "Valid post submission --" do

    it "should log in a user and redirect to new post" do

      # Sign in works find, so I won't reproduce it

      # Make a blogpost
      Post.destroy_all
      fill_in :name_here, with: "Post Name Here"
      fill_in :content_here, with: "This is the content of a really short post."
      screenshot_and_open_image
      click_on "Post It"
      screenshot_and_open_image
      puts current_path
      page.should have_selector 'h2', text: "prohibited this post"
      page.should have_selector 'h1', text: "Post Name Here"
      page.should have_selector '.alert', text: "Post was successfully created."
      page.should have_selector 'title', text: full_title('Post Name Here')

    end

屏幕截图和放置是为了澄清发生了什么。基本上有两种不同的情况。在

  1. 我只是保留这些字段并测试默认 ID（“post_name”和“post_content”）；显然上述测试是针对情况二的：
  2. 我将字段 id 更改为“name_here”和“content_here”，以测试标签名称或其他任何内容是否存在干扰。那就是上面的规格。

在情况 2 中，帖子被拒绝，因为 Capybara 找不到任何一个字段。

在情况 1 中，只有内容为空，但名称字段将填充内容。

情况 1 中的精确错误是：

2) Posts Invalid post - should refresh with error if content empty
     Screenshot: /Users/myusername/rails/appname/tmp/capybara/screenshot_2013-03-14-22-37-36.634.png
     Failure/Error: fill_in :post_name, with: "Post Name Here"
     Capybara::ElementNotFound:
       cannot fill in, no text field, text area or password field with id, name, or label 'post_name' found
     # (eval):2:in `fill_in'
     # ./spec/requests/posts_spec.rb:43:in `block (3 levels) in <top (required)>'

案例 2 不会引发关于找不到适当内容的错误，我相信是因为标签也具有该 id。

这很荒谬，因为我在测试期间拍摄了 HTML 的快照，就在它出错之前。这是案例 2——除了 ID 不同之外，这两种情况看起来 90% 相同：

<form accept-charset="UTF-8" action="/posts" class="new_post" id="new_post" method="post">
 <div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="✓"></div>
 <div class="field">
  <label for="post_name">Name</label>
   <br><input id="name_here" name="post[name]" size="30" type="text">
 </div>
 <div class="field text-area">
  <label for="post_content">Content</label>
  <br><textarea cols="50" id="content_here" name="post[content]" rows="20"></textarea>
 </div>
 <div class="actions btn-group">
  <input class="btn" name="commit" type="submit" value="Post It">
 </div>
</form>

请注意 post_content 字段的明确存在。在两者都失败的情况下（案例 1），同时存在 content_here 和 name_here 字段。所以领域就在那里。水豚通常可以正常工作（这种事情可以在我的应用程序的其他部分找到）。问题不在于标签名称冲突，因为在输入字段上放置不同的 id 无助于水豚找到它们。

顺便说一句，这一切在现实中都完美无缺。

知道这里发生了什么吗？我非常沮丧/一无所知。

更新——按照 user2172816 的建议，我更改了 HAML，因此 HTML 如下所示：

<form accept-charset="UTF-8" action="/posts" class="new_post" id="new_post" method="post">
 <div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="✓"></div>
 <div class="field">
  <label for="post_name">Name</label>
  <br><input id="name" name="post[name]" size="30" type="text">
 </div>
 <div class="field text-area">
  <label for="post_content">Content</label>
  <br><textarea cols="50" id="content" name="post[content]" rows="20"></textarea>
 </div>
 <div class="actions btn-group">
  <input class="btn" name="commit" type="submit" value="Post It">
 </div>
</form>

测试现在看起来像这样：

 # Make a blogpost
  Post.destroy_all
  fill_in "Name", with: "Post Name Here"
  fill_in "Content", with: "This is the content of a really short post."
  page.should have_selector 'h2', text: "prohibited this post"
  page.should have_selector 'h1', text: "Post Name Here"
  page.should have_selector '.alert', text: "Post was successfully created."
  page.should have_selector 'title', text: full_title('Post Name Here')

但它仍然出错（在同一规范的新部分中也是如此！）：

  1) Posts Invalid post - should refresh with error if content empty

label 的属性“for”应该是输入元素的“id”，即

<label for="name_here">Name</label>
   <br><input id="name_here" name="post[name]" size="30" type="text">

在规范中，您应该调用：

fill_in 'Name', with: "Post Name Here"
