I have an erb template in which I need to use:
CGI.unescapeHTML(someEscapedHTML)
So I need to require ‘cgi’, however the following fails:
<% require 'cgi' %>
With the error:
can’t dup NilClass
First of all do not require gems or libraries in ERB please. Then CGI is required by Rails itself already.
If you want to prevent Rails 3 from auto-escaping consider using
<%= data.html_safe %>instead.
