oops, need file_column for legacy support

vendor/plugins/file_column/CHANGELOG

@@ -0,0 +1,69 @@
+*svn*
+    * allow for directories in file_column dirs as well
+    * use subdirs for versions instead of fiddling with filename
+    * url_for_image_column_helper for dynamic resizing of images from views
+    * new "crop" feature [Sean Treadway]
+    * url_for_file_column helper: do not require model objects to be stored in
+      instance variables
+    * allow more fined-grained control over :store_dir via callback
+      methods [Gerret Apelt]
+    * allow assignment of regular file objects
+    * validation of file format and file size [Kyle Maxwell]
+    * validation of image dimensions [Lee O'Mara]
+    * file permissions can be set via :permissions option
+    * fixed bug that prevents deleting of file via assigning nil if
+      column is declared as NON NULL on some databases
+    * don't expand absolute paths. This is necessary for file_column to work
+      when your rails app is deployed into a sub-directory via a symbolic link
+    * url_for_*_column will no longer return absolute URLs! Instead, although the
+      generated URL starts with a slash, it will be relative to your application's
+      root URL. This is so, because rails' image_tag helper will automatically
+      convert it to an absolute URL. If you need an absolute URL (e.g., to pass
+      it to link_to) use url_for_file_column's :absolute => true option.
+    * added support for file_column enabled unit tests [Manuel Holtgrewe]
+    * support for custom transformation of images [Frederik Fix]
+    * allow setting of image attributes (e.g., quality) [Frederik Fix]
+    * :magick columns can optionally ignore non-images (i.e., do not try to
+       resize them)
+
+0.3.1
+    * make object with file_columns serializable
+    * use normal require for RMagick, so that it works with gem
+      and custom install as well
+
+0.3
+    * fixed bug where empty file uploads were not recognized with some browsers
+    * fixed bug on windows when "file" utility is not present
+    * added option to disable automatic file extension correction
+    * Only allow one attribute per call to file_column, so that options only
+      apply to one argument
+    * try to detect when people forget to set the form encoding to
+      'multipart/form-data'
+    * converted to rails plugin
+    * easy integration with RMagick
+
+0.2
+    * complete rewrite using state pattern
+    * fixed sanitize filename [Michael Raidel]
+    * fixed bug when no file was uploaded [Michael Raidel]
+    * try to fix filename extensions [Michael Raidel]
+    * Feed absolute paths through File.expand_path to make them as simple as possible
+    * Make file_column_field helper work with auto-ids (e.g., "event[]")
+
+0.1.3
+    * test cases with more than 1 file_column
+    * fixed bug when file_column was called with several arguments
+    * treat empty ("") file_columns as nil
+    * support for binary files on windows
+
+0.1.2
+    * better rails integration, so that you do not have to include the modules yourself. You
+      just have to "require 'rails_file_column'" in your "config/environment.rb"
+    * Rakefile for testing and packaging
+
+0.1.1 (2005-08-11)
+    * fixed nasty bug in url_for_file_column that made it unusable on Apache
+    * prepared for public release
+
+0.1 (2005-08-10)
+    * initial release

+FEATURES
+========
+
+Let's assume an model class named Entry, where we want to define the "image" column
+as a "file_upload" column.
+
+class Entry < ActiveRecord::Base
+  file_column :image
+end
+
+* every entry can have one uploaded file, the filename will be stored in the "image" column
+
+* files will be stored in "public/entry/image/<entry.id>/filename.ext"
+
+* Newly uploaded files will be stored in "public/entry/tmp/<random>/filename.ext" so that
+  they can be reused in form redisplays (due to validation etc.)
+
+* in a view, "<%= file_column_field 'entry', 'image' %> will create a file upload field as well
+  as a hidden field to recover files uploaded before in a case of a form redisplay
+
+* in a view, "<%= url_for_file_column 'entry', 'image' %> will create an URL to access the
+  uploaded file. Note that you need an Entry object in the instance variable @entry for this
+  to work.
+
+* easy integration with RMagick to resize images and/or create thumb-nails.
+
+USAGE
+=====
+
+Just drop the whole directory into your application's "vendor/plugins" directory. Starting
+with version 1.0rc of rails, it will be automatically picked for you by rails plugin
+mechanism.
+
+DOCUMENTATION
+=============
+
+Please look at the rdoc-generated documentation in the "doc" directory.
+
+RUNNING UNITTESTS
+=================
+
+There are extensive unittests in the "test" directory. Currently, only MySQL is supported, but
+you should be able to easily fix this by looking at "connection.rb". You have to create a
+database for the tests and put the connection information into "connection.rb". The schema
+for MySQL can be found in "test/fixtures/mysql.sql".
+
+You can run the tests by starting the "*_test.rb" in the directory "test"
+
+BUGS & FEEDBACK
+===============
+
+Bug reports (as well as patches) and feedback are very welcome. Please send it to
