Nil gsub when img with src and filter_html is on
Reported by Jason Garber | November 29th, 2010 @ 07:17 PM
Hi there.
I'm using RedCloth as part of a social network's blog system.
I came across the following bug when an img tag with the src
attribute
is inputted, and filter_html is set to true.
I have pasted the code sample below.
>> require 'RubyGems' => true >> require
'RedCloth' => true >> RedCloth.new('',[:filter_html]).to_html NoMethodError: private method
