Feedzirra on Rails3
I am using Feedzirra in one of my projects. I was trying to experiment my app with Rails3 and found the following issue when using Feedzirra. This is just a hack to get it to work, I am sure there are better ways to solve it. The issue is Feedzirra uses Loofah library for html scrubbing. Loofah makes some assumptions about the Rails framework as in code on line# 86 here
if defined? Rails.configuration and Rails.configuration.frameworks.include?([:active_record]) # rails 2.1 and later
Rails.configuration.after_initialize do
require 'loofah/active_record'
require 'loofah/xss_foliate'
end
elsif defined? ActiveRecord::Base # rails 2.0
require 'loofah/active_record'
require 'loofah/xss_foliate'
end
As per new changes in Rails3 (framework agnostic), config.frameworks is deprecated causing the following error config.frameworks in no longer supported. See the generated config/boot.rb for steps on how to limit the frameworks that will be loaded (RuntimeError).
To get around this I have made the following change
loofah.rb line# 86
begin
if defined? ActiveRecord::Base
require 'loofah/active_record'
require 'loofah/xss_foliate'
elsif defined? Rails.configuration and Rails.configuration.frameworks.include?([:active_record]) # rails 2.1 and later
Rails.configuration.after_initialize do
require 'loofah/active_record'
require 'loofah/xss_foliate'
end
end
rescue
#handle the error accordingly
end
Add new gem group to Gemfile of rails3 app
group :after_initialize do
gem "feedzirra", :git => "git://github.com/chrismsnz/feedzirra.git"
end
Now tell Bundler to load feedzirra after application initializtion by changing application.rb of rails3 app like this
Bundler.require :after_initialize
BTW I used the forked Feedzirra branch of chrismsnz available here instead of original pauldix tree.
Hope this helps someone.
