+ # The FileColumn module allows you to easily handle file uploads. You can designate
+ # one or more columns of your model's table as "file columns" like this:
+ #
+ # class Entry < ActiveRecord::Base
+ #
+ # file_column :image
+ # end
+ #
+ # Now, by default, an uploaded file "test.png" for an entry object with primary key 42 will
+ # be stored in in "public/entry/image/42/test.png". The filename "test.png" will be stored
+ # in the record's "image" column. The "entries" table should have a +VARCHAR+ column
+ # named "image".
+ #
+ # The methods of this module are automatically included into <tt>ActiveRecord::Base</tt>
+ # as class methods, so that you can use them in your models.
+ #
+ # == Generated Methods
+ #
+ # After calling "<tt>file_column :image</tt>" as in the example above, a number of instance methods
+ # will automatically be generated, all prefixed by "image":
+ #
+ # * <tt>Entry#image=(uploaded_file)</tt>: this will handle a newly uploaded file
+ # (see below). Note that
+ # you can simply call your upload field "entry[image]" in your view (or use the
+ # helper).
+ # * <tt>Entry#image(subdir=nil)</tt>: This will return an absolute path (as a
+ # string) to the currently uploaded file
+ # or nil if no file has been uploaded
+ # * <tt>Entry#image_relative_path(subdir=nil)</tt>: This will return a path relative to
+ # this file column's base directory
+ # as a string or nil if no file has been uploaded. This would be "42/test.png" in the example.
+ # * <tt>Entry#image_just_uploaded?</tt>: Returns true if a new file has been uploaded to this instance.
+ # You can use this in your code to perform certain actions (e. g., validation,
+ # custom post-processing) only on newly uploaded files.
+ #
+ # You can access the raw value of the "image" column (which will contain the filename) via the
+ # <tt>ActiveRecord::Base#attributes</tt> or <tt>ActiveRecord::Base#[]</tt> methods like this:
+ #
+ # entry['image'] # e.g."test.png"
+ #
+ # == Storage of uploaded files
+ #
+ # For a model class +Entry+ and a column +image+, all files will be stored under
+ # "public/entry/image". A sub-directory named after the primary key of the object will
+ # be created, so that files can be stored using their real filename. For example, a file
+ # "test.png" stored in an Entry object with id 42 will be stored in
+ #
+ # public/entry/image/42/test.png
+ #
+ # Files will be moved to this location in an +after_save+ callback. They will be stored in
+ # a temporary location previously as explained in the next section.
+ #
+ # By default, files will be created with unix permissions of <tt>0644</tt> (i. e., owner has
+ # read/write access, group and others only have read access). You can customize
+ # this by passing the desired mode as a <tt>:permissions</tt> options. The value
+ # you give here is passed directly to <tt>File::chmod</tt>, so on Unix you should
+ # give some octal value like 0644, for example.
+ #
+ # == Handling of form redisplay
+ #
+ # Suppose you have a form for creating a new object where the user can upload an image. The form may
+ # have to be re-displayed because of validation errors. The uploaded file has to be stored somewhere so
+ # that the user does not have to upload it again. FileColumn will store these in a temporary directory
+ # (called "tmp" and located under the column's base directory by default) so that it can be moved to
+ # the final location if the object is successfully created. If the form is never completed, though, you
+ # can easily remove all the images in this "tmp" directory once per day or so.
+ #
+ # So in the example above, the image "test.png" would first be stored in
+ # "public/entry/image/tmp/<some_random_key>/test.png" and be moved to
+ # "public/entry/image/<primary_key>/test.png".
+ #
+ # This temporary location of newly uploaded files has another advantage when updating objects. If the
+ # update fails for some reasons (e.g. due to validations), the existing image will not be overwritten, so
+ # it has a kind of "transactional behaviour".
+ #
+ # == Additional Files and Directories
+ #
+ # FileColumn allows you to keep more than one file in a directory and will move/delete
+ # all the files and directories it finds in a model object's directory when necessary.
+ #
+ # As a convenience you can access files stored in sub-directories via the +subdir+
+ # parameter if they have the same filename.
+ #
+ # Suppose your uploaded file is named "vancouver.jpg" and you want to create a
+ # thumb-nail and store it in the "thumb" directory. If you call
+ # <tt>image("thumb")</tt>, you
+ # will receive an absolute path for the file "thumb/vancouver.jpg" in the same
+ # directory "vancouver.jpg" is stored. Look at the documentation of FileColumn::Magick
+ # for more examples and how to create these thumb-nails automatically.
+ #
+ # == File Extensions
+ #
+ # FileColumn will try to fix the file extension of uploaded files, so that
+ # the files are served with the correct mime-type by your web-server. Most
+ # web-servers are setting the mime-type based on the file's extension. You
+ # can disable this behaviour by passing the <tt>:fix_file_extensions</tt> option
+ # with a value of +nil+ to +file_column+.
+ #
+ # In order to set the correct extension, FileColumn tries to determine
+ # the files mime-type first. It then uses the +MIME_EXTENSIONS+ hash to
+ # choose the corresponding file extension. You can override this hash
+ # by passing in a <tt>:mime_extensions</tt> option to +file_column+.
+ #
+ # The mime-type of the uploaded file is determined with the following steps:
+ #
+ # 1. Run the external "file" utility. You can specify the full path to
+ # the executable in the <tt>:file_exec</tt> option or set this option
+ # to +nil+ to disable this step
+ #
+ # 2. If the file utility couldn't determine the mime-type or the utility was not
+ # present, the content-type provided by the user's browser is used
+ # as a fallback.
+ #
+ # == Custom Storage Directories
+ #
+ # FileColumn's storage location is determined in the following way. All
+ # files are saved below the so-called "root_path" directory, which defaults to
+ # "RAILS_ROOT/public". For every file_column, you can set a separte "store_dir"
+ # option. It defaults to "model_name/attribute_name".
+ #
+ # Files will always be stored in sub-directories of the store_dir path. The
+ # subdirectory is named after the instance's +id+ attribute for a saved model,
+ # or "tmp/<randomkey>" for unsaved models.
+ #
+ # You can specify a custom root_path by setting the <tt>:root_path</tt> option.
+ #
+ # You can specify a custom storage_dir by setting the <tt>:storage_dir</tt> option.
+ #
+ # For setting a static storage_dir that doesn't change with respect to a particular
+ # instance, you assign <tt>:storage_dir</tt> a String representing a directory
+ # as an absolute path.
+ #
+ # If you need more fine-grained control over the storage directory, you
+ # can use the name of a callback-method as a symbol for the
+ # <tt>:store_dir</tt> option. This method has to be defined as an
+ # instance method in your model. It will be called without any arguments
+ # whenever the storage directory for an uploaded file is needed. It should return
+ # a String representing a directory relativeo to root_path.
+ #
+ # Uploaded files for unsaved models objects will be stored in a temporary
+ # directory. By default this directory will be a "tmp" directory in
+ # your <tt>:store_dir</tt>. You can override this via the
+ # <tt>:tmp_base_dir</tt> option.

+ # * a <tt>:symbol</tt> will select a version defined in the model
+ # via FileColumn::Magick's <tt>:versions</tt> feature.
+ # * a <tt>geometry_string</tt> will dynamically create an
+ # image resized as specified by <tt>geometry_string</tt>. The image will
+ # be stored so that it does not have to be recomputed the next time the
+ # same version string is used.
+ # * <tt>some_hash</tt> will dynamically create an image
+ # that is created according to the options in <tt>some_hash</tt>. This
+ # accepts exactly the same options as Magick's version feature.
+ #
+ # The version produced by RMagick will be stored in a special sub-directory.
+ # The directory's name will be derived from the options you specified
+ # (via a hash function) but if you want
+ # to set it yourself, you can use the <tt>:name => name</tt> option.
+ #
+ # Examples:
+ #
+ # <%= url_for_image_column @entry, "image", "640x480" %>
+ #
+ # will produce an URL like this
+ #
+ # /entry/image/42/bdn19n/filename.jpg
+ # # "640x480".hash.abs.to_s(36) == "bdn19n"

+ # <%= url_for_image_column @entry, "image",

+ # will produce something like this:
+ #
+ # /entry/image/42/thumb/filename.jpg
+ #
+ # Hint: If you are using the same geometry string / options hash multiple times, you should
+ # define it in a helper to stay with DRY. Another option is to define it in the model via
+ # FileColumn::Magick's <tt>:versions</tt> feature and then refer to it via a symbol.
+ #
+ # The URL produced by this method is relative to your application's root URL,

+ # If you are using file_column to upload images, you can
+ # directly process the images with RMagick,
+ # a ruby extension
+ # for accessing the popular imagemagick libraries. You can find
+ # more information about RMagick at http://rmagick.rubyforge.org.
+ #
+ # You can control what to do by adding a <tt>:magick</tt> option
+ # to your options hash. All operations are performed immediately
+ # after a new file is assigned to the file_column attribute (i.e.,
+ # when a new file has been uploaded).
+ #
+ # == Resizing images
+ #
+ # To resize the uploaded image according to an imagemagick geometry
+ # string, just use the <tt>:size</tt> option:
+ #
+ # file_column :image, :magick => {:size => "800x600>"}
+ #
+ # If the uploaded file cannot be loaded by RMagick, file_column will
+ # signal a validation error for the corresponding attribute. If you
+ # want to allow non-image files to be uploaded in a column that uses
+ # the <tt>:magick</tt> option, you can set the <tt>:image_required</tt>
+ # attribute to +false+:
+ #
+ # file_column :image, :magick => {:size => "800x600>",
+ # :image_required => false }
+ #
+ # == Multiple versions
+ #
+ # You can also create additional versions of your image, for example
+ # thumb-nails, like this:
+ # file_column :image, :magick => {:versions => {
+ # :thumb => {:size => "50x50"},
+ # :medium => {:size => "640x480>"}
+ # }
+ #
+ # These versions will be stored in separate sub-directories, named like the
+ # symbol you used to identify the version. So in the previous example, the
+ # image versions will be stored in "thumb", "screen" and "widescreen"
+ # directories, resp.
+ # A name different from the symbol can be set via the <tt>:name</tt> option.
+ #
+ # These versions can be accessed via FileColumnHelper's +url_for_image_column+
+ # method like this:
+ #
+ # <%= url_for_image_column "entry", "image", :thumb %>
+ #
+ # == Cropping images
+ #
+ # If you wish to crop your images with a size ratio before scaling
+ # them according to your version geometry, you can use the :crop directive.
+ # file_column :image, :magick => {:versions => {
+ # :square => {:crop => "1:1", :size => "50x50", :name => "thumb"},
+ # :screen => {:crop => "4:3", :size => "640x480>"},
+ # :widescreen => {:crop => "16:9", :size => "640x360!"},
+ # }
+ # }
+ #
+ # == Custom attributes
+ #
+ # To change some of the image properties like compression level before they
+ # are saved you can set the <tt>:attributes</tt> option.
+ # For a list of available attributes go to http://www.simplesystems.org/RMagick/doc/info.html
+ #
+ # file_column :image, :magick => { :attributes => { :quality => 30 } }
+ #
+ # == Custom transformations
+ #
+ # To perform custom transformations on uploaded images, you can pass a
+ # callback to file_column:
+ # file_column :image, :magick =>
+ # Proc.new { |image| image.quantize(256, Magick::GRAYColorspace) }
+ #
+ # The callback you give, receives one argument, which is an instance
+ # of Magick::Image, the RMagick image class. It should return a transformed
+ # image. Instead of passing a <tt>Proc</tt> object, you can also give a
+ # <tt>Symbol</tt>, the name of an instance method of your model.
+ #
+ # Custom transformations can be combined via the standard :size and :crop
+ # features, by using the :transformation option:
+ # file_column :image, :magick => {
+ # :transformation => Proc.new { |image| ... },
+ # :size => "640x480"
+ # }
+ #
+ # In this case, the standard resizing operations will be performed after the
+ # custom transformation.
+ #
+ # Of course, custom transformations can be used in versions, as well.
+ #

+ # RMagick extension being installed in order to use file_column's
+ # imagemagick integration.
