Question

Users at my website are able to write comments through special form. Field for value is a normal textarea. Now every comment is displayed without any html tags. It looks kinda weird when someone for instance post long comment. I would like to filter out value from all tags except new line chars (\n or \r\n).

I display that comments like that: <%=h @comment.value %>

What should I change? I was thinking about writing whole new method to filter all tags expect new line chars but I am sure that Ruby on Rails offers easier solution here.

Answer 1

use simple_format and h together

<%= simple_format(h(@comment.value)) %>

simple_format essentially use gsub to convert line break into <br> and <p> tags.
