Question

set tabstop=4
set shiftwidth=4
set nu
set ai
syntax on
filetype plugin indent on

I tried this, content.gsub("\r\n","<br/>") but when I click the view/show button to see the contents of these line, I get the output/result=>

set tabstop=4<br/> set shiftwidth=4<br/> set nu<br/> set ai<br/> syntax on<br/> filetype plugin indent on

But I tried to get those lines as a seperate lines. But all become as a single line. Why?

How can I make all those lines with a html break (<br/>) ?

I tried this, that didn’t work.

@addpost = Post.new params[:data]
@temptest = @addpost.content.html_safe
@addpost.content = @temptest
#logger.debug(@addpost)
@addpost.save

Also tried without saving into database. Tried only in view layer,<%= t.content.html_safe %> That didn’t work too.

Got this from page source

        <a href="/posts/36">vimrc file</a> <br/>
        2011-12-06<br/><br/>

        set tabstop=4&lt;br/&gt;&lt;br/&gt;set shiftwidth=4&lt;br/&gt;&lt;br/&gt;set nu&lt;br/&gt;&lt;br/&gt;set ai&lt;br/&gt;&lt;br/&gt;syntax on&lt;br/&gt;&lt;br/&gt;filetype plugin indent on<br/>

            <a href="/posts/36/edit">Edit</a>
            <a href="/posts/36" data-confirm="Are you sure?" data-method="delete" rel="nofollow">Delete</a>
        <br/><br/>

You need to use html_safe if you want to render embedded HTML:

<%= @the_string.html_safe %>

If it might be nil, raw(@the_string) won’t throw an exception. I’m a bit ambivalent about raw; I almost never try to display a string that might be nil.
