如何阻止 auto_link 转义尖括号？
我希望我的应用程序允许用户在他们的帖子中发布链接，并自动识别这些链接。为此，我一直在使用 auto_link ：以下是被调用以显示个人帖子的部分内容：
_post.html.erb：
<tr>
<td >
<span class="post_header"><h4><%= link_to "#{post.user.first_name} #{post.user.last_name}", post.user %></h4></span>
<p> <%= auto_link(post.content) %> </p>
<span class="post_timestamp">
Opined <%= time_ago_in_words(post.created_at) %> ago
</span>
</td>
</tr>
对于单个 post.content 输出以下内容：
<p> Wondering if this link <a href="http://www.economist.com/blogs/freeexchange">http://www.economist.com/blogs/freeexchange</a> will become a proper link
为什么自动链接会创建/转义尖括号到
Wondering if this link <a href="http://www.economist.com/blogs/freeexchange">http://www.economist.com/blogs/freeexchange</a> will become a proper link
I would like for my app to allow users to post links in their posts, and for those links to automatically be recognized. To do so, I have been using auto_link as such: the following is the partial that is called to show a person's post:
_post.html.erb:
<tr>
<td >
<span class="post_header"><h4><%= link_to "#{post.user.first_name} #{post.user.last_name}", post.user %></h4></span>
<p> <%= auto_link(post.content) %> </p>
<span class="post_timestamp">
Opined <%= time_ago_in_words(post.created_at) %> ago
</span>
</td>
</tr>
this outputs the following, for a single post.content:
<p> Wondering if this link <a href="http://www.economist.com/blogs/freeexchange">http://www.economist.com/blogs/freeexchange</a> will become a proper link
Why does auto-link create/escape the angle brackets to <a etc? Is there some way to fix this, as this does not create working links. Instead the output in the browser is:
Wondering if this link <a href="http://www.economist.com/blogs/freeexchange">http://www.economist.com/blogs/freeexchange</a> will become a proper link

请注意，Rails 3.1 中删除了 auto_link。

Note that auto_link was removed with Rails 3.1.
