NoMethodError: undefined method `has_attached_file'
Solution 1
Update 06-21-10: the thoughtbot version has been fixed.
I had to add Paperclip::Railtie.insert
to my application.rb at the end of class Application < Rails::Application
to get it to work correctly. I have deleted my fork since the official repo is working. Hope that helps someone.
You will also need to add the following to your Gemfile
gem "paperclip", :git => "http://github.com/thoughtbot/paperclip.git"
Solution 2
I have a paperclip fork, you can try if it will work at your end, just change your Gemfile:
gem 'paperclip', :git => 'git://github.com/lmumar/paperclip.git', :branch => 'rails3'
Don't forget to run bundle install after updating your Gemfile.
Hope it will fix your problems.

minter's fork worked for me:
gem 'paperclip', :git => 'http://github.com/minter/paperclip.git', :branch => 'rails3'
Solution 4
That didn't work for me. I have done below things and it is working perfectly:
- Add "Paperclip::Railtie.insert" in application.rb
- Add "config.gem 'paperclip'" in development.rb

Paperclip produces this error, after checking out the plugin's rails3 branch. My Gemfile has following line:
gem 'paperclip', :git => 'http://github.com/thoughtbot/paperclip.git', :branch => 'rails3'
And the error message is:
NoMethodError: undefined method `has_attached_file' for #<Class:0x2a50530>
