I followed the railscasts about using carrierwave with fog with aws s3 to the T but it doesnt seem to work.
The Gemfile is as follows:
source 'https://rubygems.org'
ruby '1.9.3'
gem 'rails', '3.2.13'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'pg'
gem 'pg_search'
gem 'devise'
gem "therubyracer"
gem "less-rails" #Sprockets (what Rails 3.1 uses for its asset pipeline) supports LESS
gem "twitter-bootstrap-rails", :git => 'git://github.com/seyhunak/twitter-bootstrap-rails.git'
gem "simple_form"
gem 'aws-sdk', '~> 1.8.1.2'
gem 'activerecord-reputation-system', require: 'reputation_system'
gem 'bootstrap-will_paginate'
gem 'carrierwave'
gem "rmagick"
gem "fog", "~> 1.3.1"
gem 'carrierwave-aws'
config/initializers/carrierwave.rb
require 'carrierwave'
CarrierWave.configure do |config|
config.fog_credentials = {
provider: "AWS",
aws_access_key_id: ENV["xxx"],
aws_secret_access_key: ENV["yyy"],
region: ENV['ap-southeast-1']
}
config.cache_dir = "#{Rails.root}/tmp/uploads"
config.fog_directory = ENV["ABC"]
end
The uploader:
class ImageUploader < CarrierWave::Uploader::Base
require 'carrierwave/processing/mime_types'
before :store, :remember_cache_id
after :store, :delete_tmp_dir
# Include RMagick or MiniMagick support:
include CarrierWave::RMagick
# include CarrierWave::MiniMagick
# Include the Sprockets helpers for Rails 3.1+ asset pipeline compatibility:
include Sprockets::Helpers::RailsHelper
include Sprockets::Helpers::IsolatedHelper
# Choose what kind of storage to use for this uploader:
# storage :file
storage :fog
include CarrierWave::MimeTypes
process :set_content_type
# Override the directory where uploaded files will be stored.
# This is a sensible default for uploaders that are meant to be mounted:
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
version :thumb do
process :resize_to_limit => [200, 200]
end
# store! nil's the cache_id after it finishes so we need to remember it for deletion
def remember_cache_id(new_file)
@cache_id_was = cache_id
end
def delete_tmp_dir(new_file)
# make sure we don't delete other things accidentally by checking the name pattern
if @cache_id_was.present? && @cache_id_was =~ /\A[\d]{8}\-[\d]{4}\-[\d]+\-[\d]{4}\z/
FileUtils.rm_rf(File.join(root, cache_dir, @cache_id_was))
end
end
end
the controller:
class NotesController < ApplicationController
before_filter :authenticate_user!, only: [:create, :destroy]
before_filter :correct_user, only: :destroy
def index
end
def create
@note = current_user.notes.build(params[:note])
@notes = Note.paginate(page: params[:page])
if @note.save
flash[:success] = "Note uploaded!"
redirect_to root_url
else
flash.now[:error] = "Note failed to upload."
render 'static_pages/home'
end
end
def destroy
@note.destroy
flash[:success] = "Note deleted."
redirect_to root_url
end
private
def correct_user
@note = current_user.notes.find_by_id(params[:id])
redirect_to root_url if @note.nil?
end
end
I don't really know if the problem lies in the gem or the controller. Even the controller is based on the microposts controller in Michael Hartl's book "The Ruby on Rails Tutorial" so I don't know where I have gone wrong.
