attachment-fu
=====================
attachment_fu is a plugin by Rick Olson (aka technoweenie <http://techno-weenie.net>) and is the successor to acts_as_attachment. To get a basic run-through of its capabilities, check out Mike Clark's tutorial <http://clarkware.com/cgi/blosxom/2007/02/24#FileUploadFu>.
attachment_fu functionality
===========================
attachment_fu facilitates file uploads in Ruby on Rails. There are a few storage options for the actual file data, but the plugin always at a minimum stores metadata for each file in the database.
There are three storage options for files uploaded through attachment_fu:
File system
Database file
Amazon S3
Each method of storage many options associated with it that will be covered in the following section. Something to note, however, is that the Amazon S3 storage requires you to modify config/amazon_s3.yml and the Database file storage requires an extra table.
attachment_fu models
====================
For all three of these storage options a table of metadata is required. This table will contain information about the file (hence the 'meta') and its location. This table has no restrictions on naming, unlike the extra table required for database storage, which must have a table name of db_files (and by convention a model of DbFile).
In the model there are two methods made available by this plugins: has_attachment and validates_as_attachment.
has_attachment(options = {})
This method accepts the options in a hash:
:content_type # Allowed content types.
# Allows all by default. Use :image to allow all standard image types.
:min_size # Minimum size allowed.
# 1 byte is the default.
:max_size # Maximum size allowed.
# 1.megabyte is the default.
:size # Range of sizes allowed.
# (1..1.megabyte) is the default. This overrides the :min_size and :max_size options.
:resize_to # Used by RMagick to resize images.
# Pass either an array of width/height, or a geometry string.
:thumbnails # Specifies a set of thumbnails to generate.
# This accepts a hash of filename suffixes and RMagick resizing options.
# This option need only be included if you want thumbnailing.
:thumbnail_class # Set which model class to use for thumbnails.
# This current attachment class is used by default.
:path_prefix # path to store the uploaded files.
# Uses public/#{table_name} by default for the filesystem, and just #{table_name} for the S3 backend.
# Setting this sets the :storage to :file_system.
:storage # Specifies the storage system to use..
# Defaults to :db_file. Options are :file_system, :db_file, and :s3.
:processor # Sets the image processor to use for resizing of the attached image.
# Options include ImageScience, Rmagick, and MiniMagick. Default is whatever is installed.
Examples:
has_attachment :max_size => 1.kilobyte
has_attachment :size => 1.megabyte..2.megabytes
has_attachment :content_type => 'application/pdf'
has_attachment :content_type => ['application/pdf', 'application/msword', 'text/plain']
has_attachment :content_type => :image, :resize_to => [50,50]
has_attachment :content_type => ['application/pdf', :image], :resize_to => 'x50'
has_attachment :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }
has_attachment :storage => :file_system, :path_prefix => 'public/files'
has_attachment :storage => :file_system, :path_prefix => 'public/files',
:content_type => :image, :resize_to => [50,50]
has_attachment :storage => :file_system, :path_prefix => 'public/files',
:thumbnails => { :thumb => [50, 50], :geometry => 'x50' }
has_attachment :storage => :s3
validates_as_attachment
This method prevents files outside of the valid range (:min_size to :max_size, or the :size range) from being saved. It does not however, halt the upload of such files. They will be uploaded into memory regardless of size before validation.
Example:
validates_as_attachment
attachment_fu migrations
========================
Fields for attachment_fu metadata tables...
in general:
size, :integer # file size in bytes
content_type, :string # mime type, ex: application/mp3
filename, :string # sanitized filename
that reference images:
height, :integer # in pixels
width, :integer # in pixels
that reference images that will be thumbnailed:
parent_id, :integer # id of parent image (on the same table, a self-referencing foreign-key).
# Only populated if the current object is a thumbnail.
thumbnail, :string # the 'type' of thumbnail this attachment record describes.
# Only populated if the current object is a thumbnail.
# Usage:
# [ In Model 'Avatar' ]
# has_attachment :content_type => :image,
# :storage => :file_system,
# :max_size => 500.kilobytes,
# :resize_to => '320x200>',
# :thumbnails => { :small => '10x10>',
# :thumb => '100x100>' }
# [ Elsewhere ]
# @user.avatar.thumbnails.first.thumbnail #=> 'small'
that reference files stored in the database (:db_file):
db_file_id, :integer # id of the file in the database (foreign key)
Field for attachment_fu db_files table:
data, :binary # binary file data, for use in database file storage
attachment_fu views
===================
There are two main views tasks that will be directly affected by attachment_fu: upload forms and displaying uploaded images.
There are two parts of the upload form that differ from typical usage.
1. Include ':multipart => true' in the html options of the form_for tag.
Example:
<% form_for(:attachment_metadata, :url => { :action => "create" }, :html => { :multipart => true }) do |form| %>
2. Use the file_field helper with :uploaded_data as the field name.
Example:
<%= form.file_field :uploaded_data %>
Displaying uploaded images is made easy by the public_filename method of the ActiveRecord attachment objects using file system and s3 storage.
public_filename(thumbnail = nil)
Returns the public path to the file. If a thumbnail prefix is specified it will return the public file path to the corresponding thumbnail.
Examples:
attachment_obj.public_filename #=> /attachments/2/file.jpg
attachment_obj.public_filename(:thumb) #=> /attachments/2/file_thumb.jpg
attachment_obj.public_filename(:small) #=> /attachments/2/file_small.jpg
When serving files from database storage, doing more than simply downloading the file is beyond the scope of this document.
attachment_fu controllers
=========================
There are two considerations to take into account when using attachment_fu in controllers.
The first is when the files have no publicly accessible path and need to be downloaded through an action.
Example:
def readme
send_file '/path/to/readme.txt', :type => 'plain/text', :disposition => 'inline'
end
See the possible values for send_file for reference.
The second is when saving the file when submitted from a form.
Example in view:
<%= form.file_field :attachable, :uploaded_data %>
Example in controller:
def create
@attachable_file = AttachmentMetadataModel.new(params[:attachable])
if @attachable_file.save
flash[:notice] = 'Attachment was successfully created.'
redirect_to attachable_url(@attachable_file)
else
render :action => :new
end
end

module Technoweenie # :nodoc:
module AttachmentFu # :nodoc:
module Backends
# = AWS::S3 Storage Backend
#
# Enables use of {Amazon's Simple Storage Service}[http://aws.amazon.com/s3] as a storage mechanism
#
# == Requirements
#
# Requires the {AWS::S3 Library}[http://amazon.rubyforge.org] for S3 by Marcel Molina Jr. installed either
# as a gem or a as a Rails plugin.
#
# == Configuration
#
# Configuration is done via <tt>RAILS_ROOT/config/amazon_s3.yml</tt> and is loaded according to the <tt>RAILS_ENV</tt>.
# The minimum connection options that you must specify are a bucket name, your access key id and your secret access key.
# If you don't already have your access keys, all you need to sign up for the S3 service is an account at Amazon.
# You can sign up for S3 and get access keys by visiting http://aws.amazon.com/s3.
#
# Example configuration (RAILS_ROOT/config/amazon_s3.yml)
#
# development:
# bucket_name: appname_development
# access_key_id: <your key>
# secret_access_key: <your key>
#
# test:
# bucket_name: appname_test
# access_key_id: <your key>
# secret_access_key: <your key>
#
# production:
# bucket_name: appname
# access_key_id: <your key>
# secret_access_key: <your key>
#
# You can change the location of the config path by passing a full path to the :s3_config_path option.
#
# has_attachment :storage => :s3, :s3_config_path => (RAILS_ROOT + '/config/s3.yml')
#
# === Required configuration parameters
#
# * <tt>:access_key_id</tt> - The access key id for your S3 account. Provided by Amazon.
# * <tt>:secret_access_key</tt> - The secret access key for your S3 account. Provided by Amazon.
# * <tt>:bucket_name</tt> - A unique bucket name (think of the bucket_name as being like a database name).
#
# If any of these required arguments is missing, a MissingAccessKey exception will be raised from AWS::S3.
#
# == About bucket names
#
# Bucket names have to be globaly unique across the S3 system. And you can only have up to 100 of them,
# so it's a good idea to think of a bucket as being like a database, hence the correspondance in this
# implementation to the development, test, and production environments.
#
# The number of objects you can store in a bucket is, for all intents and purposes, unlimited.
#
# === Optional configuration parameters
#
# * <tt>:server</tt> - The server to make requests to. Defaults to <tt>s3.amazonaws.com</tt>.
# * <tt>:port</tt> - The port to the requests should be made on. Defaults to 80 or 443 if <tt>:use_ssl</tt> is set.
# * <tt>:use_ssl</tt> - If set to true, <tt>:port</tt> will be implicitly set to 443, unless specified otherwise. Defaults to false.
#
# == Usage
#
# To specify S3 as the storage mechanism for a model, set the acts_as_attachment <tt>:storage</tt> option to <tt>:s3</tt>.
#
# class Photo < ActiveRecord::Base
# has_attachment :storage => :s3
# end
#
# === Customizing the path
#
# By default, files are prefixed using a pseudo hierarchy in the form of <tt>:table_name/:id</tt>, which results
# in S3 urls that look like: http(s)://:server/:bucket_name/:table_name/:id/:filename with :table_name
# representing the customizable portion of the path. You can customize this prefix using the <tt>:path_prefix</tt>
# option:
#
# class Photo < ActiveRecord::Base
# has_attachment :storage => :s3, :path_prefix => 'my/custom/path'
# end
#
# Which would result in URLs like <tt>http(s)://:server/:bucket_name/my/custom/path/:id/:filename.</tt>
#
# === Permissions
#
# By default, files are stored on S3 with public access permissions. You can customize this using
# the <tt>:s3_access</tt> option to <tt>has_attachment</tt>. Available values are
# <tt>:private</tt>, <tt>:public_read_write</tt>, and <tt>:authenticated_read</tt>.
#
# === Other options
#
# Of course, all the usual configuration options apply, such as content_type and thumbnails:
#
# class Photo < ActiveRecord::Base
# has_attachment :storage => :s3, :content_type => ['application/pdf', :image], :resize_to => 'x50'
# has_attachment :storage => :s3, :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }
# end
#
# === Accessing S3 URLs
#
# You can get an object's URL using the s3_url accessor. For example, assuming that for your postcard app
# you had a bucket name like 'postcard_world_development', and an attachment model called Photo:
#
# @postcard.s3_url # => http(s)://s3.amazonaws.com/postcard_world_development/photos/1/mexico.jpg
#
# The resulting url is in the form: http(s)://:server/:bucket_name/:table_name/:id/:file.
# The optional thumbnail argument will output the thumbnail's filename (if any).
#
# Additionally, you can get an object's base path relative to the bucket root using
# <tt>base_path</tt>:
#
# @photo.file_base_path # => photos/1
#
# And the full path (including the filename) using <tt>full_filename</tt>:
#
# @photo.full_filename # => photos/
#
# Niether <tt>base_path</tt> or <tt>full_filename</tt> include the bucket name as part of the path.
# You can retrieve the bucket name using the <tt>bucket_name</tt> method.
