不创建 URL link

Question

app/vies/items/show.html.erb

    <h1><%= @item.name %></h1>

<ul>
    <li><%= @item.price %> руб.</li>
    <li><%= urls_to_images(@item.description) %></li>
    <li>Вес: <%= @item.weight %> кг.</li>
</ul>

app/helpers/application_helper.rb

    module ApplicationHelper

  def urls_to_images(s)
    s.gsub! /\s(http:\/\/.*?)/ , '<img src=""/>'
    s.html_safe
  end

  # def urls_to_links(s)
  # 
  # end

end

浏览器界面：

显示的文字。为什么不输出link?

Answer 1

我认为您在 urls_to_images 方法中犯了错误。试试这个 -

 def urls_to_images(s)
   s = s.gsub! /\s(http:\/\/.*?)/ , '<img src=""/>'
   s.html_safe
 end

Answer 2

def urls_to_images(s)
    s.gsub! /\s(http:\/\/.*?)(\s|\Z)/ , '<img src=""/>'
    s.html_safe
  end

**现在可以使用了**
