create_table :users do |t|
t.attachment :avatar
Also, schema-definition level syntax has been added:
add_attachment :users, :avatar
remove_attachment :users, :avatar
* Feature: Migration now support Rails 3.2+ `change` method.

If you need to interact with the generated tempfiles, please define an `after_flush_writes` method

ActiveRecord::Base.send :include, Paperclip::Glue
