Javascript Rspec，Capybara：不明确匹配，找到2个元素匹配字段'；简介'；

我刚刚用Jquery实现了一个内联表单显示/隐藏函数，我的一些规范失败了。我对答案和问题发表评论，并且可以在回复其他评论时发表评论。显示表单时，“添加注释”链接将更改为“取消”，单击“取消”后，表单将隐藏

我的规格：

scenario 'on a answer', js:true do
    submit_answer @answer.brief
    submit_comment @comment_brief, '.answers'
    expect(page).to have_content(@idea_brief)
    expect(page).to have_content(@question_brief)
    expect(page).to have_content(@answer.brief)
    expect(page).to have_content(@comment_brief)
end
scenario 'on a comment', js: true do
    @commentreply = FactoryGirl.create(:comment)
    submit_comment @comment_brief, ".question"
    submit_comment @commentreply.brief, '.question-comments', 'Reply to comment'
    expect(page).to have_content(@question_brief)
    expect(page).to have_content(@comment_reply)
end

我假设这两个错误是相同的，可能与js内联表单hide/show有关

我的失败：

1) Visitor submits a comment on a answer
 Failure/Error: submit_comment @comment_brief, '.answers'
 Capybara::Ambiguous:
   Ambiguous match, found 2 elements matching field "Brief"
 # ./spec/support/features/session_helpers.rb:52:in `submit_comment'
 # ./spec/features/comment_spec.rb:17:in `block (2 levels) in <top (required)>'

2) Visitor submits a comment on a comment
 Failure/Error: submit_comment @commentreply.brief, '.question-comments', 'Reply to   comment'
 Capybara::Ambiguous:
   Ambiguous match, found 2 elements matching field "Brief"
 # ./spec/support/features/session_helpers.rb:52:in `submit_comment'
 # ./spec/features/comment_spec.rb:33:in `block (2 levels) in <top (required)>'

此外，我还有一个等级库辅助函数：

def submit_comment(brief, selector='html', add_comment_link = 'Add comment')
  first(selector).click_link add_comment_link
  fill_in 'Brief', with: brief
  click_button 'Create Comment'
end

我将

find（）

不知道是什么导致了这一切？当我在服务器上测试同样的东西时，我没有任何问题。如果有任何其他代码有助于解决此问题，请让我知道。谢谢。
例外情况表明问题出在
行的“简短”中，用：简短
。这意味着页面上有多个“简短”元素。您需要使定位器更加具体，以便只匹配一个定位器。如果您共享生成的html以及您（作为用户）将如何区分两者，我们可以帮助您提供更好的定位器。如果您将
Capybara.match
设置为
：首选确切的
，那么会发生什么？
