I know this isn't a Rails specific question, but I thought you guys
might know how to fix this.
Background: I'm building a simple blog using Padrino, Ruby 1.9.2,
HAML, and Heroku. I want the posts index to have a magazine-like look
to it. For each post in the index, the user should see titles, content
teasers, and images. My problem is with attaching the images.
Problem: I've been trying to use the Paperclip gem to attach an image
to each post. Heroku will fish the actual image from an Amazon S3 bin.
So far, when I try to run a migration, I get the error:
$ .../base.rb:1088:in `method_missing': undefined method
`has_attached_file' for #<Class:0xa672140> (NoMethodError)
It looks like Paperclip just won't load, but there's where I get
stuck.
Details:
--Q: What am I doing when I "try to run a migration"?
--A: I put the following into the migrations folder
class AddPictureToPost < ActiveRecord::Migration
def self.up
change_table :posts do |t|
t.has_attached_file :picture
end
end
def self.down
drop_attached_file :posts, :picture
end
end
then run "padrino rake ar:migrate"
--Q: Do I have Paperclip listed in the Gemfile?
--A: Yes.
--Q: What does the post model look like?
--A:
class Post < ActiveRecord::Base
has_attached_file :picture,
:storage => :s3,
:bucket => 'blog_images',
:s3_credentials => {
:access_key_id => ENV['S3_KEY'],
:secret_access_key => ENV['S3_SECRET']
}
end
--Q: What does the app.rb look like?
--A:
class Blog < Padrino::Application
register Padrino::Rendering
register Padrino::Mailer
register Padrino::Helpers
enable :sessions
get '/' do
haml :index
end
end
--Q: What does boot.rb look like?
--A:
PADRINO_ENV = ENV["PADRINO_ENV"] ||= ENV["RACK_ENV"] ||=
"development" unless defined?(PADRINO_ENV)
PADRINO_ROOT = File.expand_path('../..', __FILE__) unless defined?
(PADRINO_ROOT)
require 'rubygems' unless defined?(Gem)
require 'bundler/setup'
Bundler.require(:default, PADRINO_ENV)
Padrino.before_load do
end
Padrino.after_load do
end
Padrino.load!
--Q: What does the full error output look like?

FWIW, despite the name, we are definitely not Rails-specific, but rather Ruby-specific. We just like the name. =)
