I'm trying to implement Paperclip in my first rails app, and I happen to be using rails 3 and mongodb with mongomapper.
I followed this guide on getting there things to all work together http://www.bencurtis.com/2009/08/paperclip-and-mongomapper/
Just as the blog post suggests, I've put paperclip into the config/initializers directory, I installed the gem, the gem is in the gemfile (rails 3 right), I ran the bundler.
In my user class, I've added
require 'paperclip'
When I load the app, I get the following error,
undefined method 'has_attached_file' for User:Class
The paperclip file looks like this
module Paperclip module ClassMethods def has_attached_file name, options = {} include InstanceMethods write_inheritable_attribute(:attachment_definitions, {}) if attachment_definitions.nil? attachment_definitions[name] = {:validations => []}.merge(options) after_save :save_attached_files before_destroy :destroy_attached_files define_callbacks :before_post_process, :after_post_process define_callbacks :"before_#{name}_post_process", :"after_#{name}_post_process" define_method name do |*args| a = attachment_for(name) (args.length > 0) ? a.to_s(args.first) : a end define_method "#{name}=" do |file| attachment_for(name).assign(file) end define_method "#{name}?" do attachment_for(name).file? end validates_each name, :logic => lambda { attachment = attachment_for(name) attachment.send(:flush_errors) unless attachment.valid? } end end module Interpolations # Handle string ids (mongo) def id_partition attachment, style if (id = attachment.instance.id).is_a?(Integer) ("%09d" % id).scan(/\d{3}/).join("/") else id.scan(/.{3}/).first(3).join("/") end end end end
Any suggestions on what I may be doing wrong? have I got the steps right?
