I have a rake task I need to run in order to sanitize (remove forward slashes) some data in the database. Here's the task:

namespace :db do
  desc "Remove slashes from old-style URLs"
  task :substitute_slashes => :environment do
    puts "Starting"
    contents = Content.all
    contents.each do |c|
      if c.permalink != nil
        c.permalink.gsub!("/","")
        c.save!
      end
    end
    puts "Finished"    
  end
end

Which allows me to run rake db:substitute_slashes --trace

If I do puts c.permalink after the gsub! I can see it's setting the attribute properly. However the save! doesn't seem to be working because the data is not changed. Can someone spot what the issue may be?

Another thing, I have paperclip installed and this task is triggering [paperclip] Saving attachments. which I would rather avoid.
