Answer 2

Can you post your Photo class?

From the logs

Paperclip::Error (Photo model missing required attr_accessor for 'image_file_name'):

It looks to me like you don't have the has_attached_file defined on your class.

From the tutorial you linked:

class Friend < ActiveRecord::Base
  # You will need to use attr_accessible if you are
  # using Rails config setting `whitelist_attributes = true`
  attr_accessible :avatar

  # This method associates the attribute ":avatar" with a file attachment
  has_attached_file :avatar, styles: {
    thumb: '100x100>',
    square: '200x200#',
    medium: '300x300>'
 }
end

If you do have this (or something similar) then you probably need to make a migration to get that column in your database:

add_attachment :photos, :image

Which will add the correct columns to your photos table.

With the has_attached_file and the columns on your table, I don't think you should have any (or at least the same) problems

Answer 3

Had this problem before!

Solved it by putting the bucket vars in the model itself (live code):

 #app/models/image.rb
 has_attached_file :image,
                :styles => { :medium => "x300", :thumb => "x100" },
                :default_url => "**********",
                :storage => :s3,
                :bucket => '*****',
                :s3_credentials => S3_CREDENTIALS

 #config/application.rb
 config.paperclip_defaults = {
            :storage => :s3,
            :s3_host_name => 's3-eu-west-1.amazonaws.com'
 }

 #config/initializers/s3.rb
 if Rails.env == "production"
     # set credentials from ENV hash
 S3_CREDENTIALS = { :access_key_id => ENV['S3_KEY'], :secret_access_key => ENV['S3_SECRET'], :bucket => "*****"}
 else
     # get credentials from YML file
     S3_CREDENTIALS = Rails.root.join("config/s3.yml")
 end

#config/application.yml ([figaro][1] gem)
S3_KEY: ********
S3_SECRET: **********

We also have this in our production.rb:

#app/environments/production.rb
config.action_controller.asset_host = "//#{ENV['FOG_DIRECTORY']}.s3.amazonaws.com"

The ENV['FOG_DIRECTORY'] is the bucket name, and there's also one for different regions. Here's a very good resource for you (the answer with 15 upvotes... not the accepted answer)
