我试图遵循Mackenziechild.me的教程。
以下是github https://github.com/ikanyu/raddit
中的代码演示应用:https://whispering-shelf-9164.herokuapp.com/links/1
任何人都可以指出为什么当我检查我创建的链接上的元素时(例如Facebook链接),我可以清楚地看到facebook。但是,当我点击链接时,它会给我错误。
LinksController中的ActiveRecord :: RecordNotFound#show
无法找到与' id' = facebook
的链接def set_link
@link = Link.find(params[:id])
end
def authorized_user
...
谢谢!

答案 0 :(得分:0)
如果您使用以下html在rails中创建链接
<a href="facebook.com">Facebook.com</a>
Rails会将您链接到YourApp.com/facebook.com(这是一个无效的网址)。
尝试重写这样的链接:
<a href="http://www.facebook.com">Facebook.com</a>
您需要将视图中的代码更改为:
<div class="page-header">
<h1><a href="http://www.<%= @link.url %>"><%= @link.title %></a><br> <small>Submitted by <%= @link.user.name %></small></h1>
</div>
或者,您可以编辑@ link.url以包含字符串&#34; http://www。&#34;
