NameError (uninitialized constant FileColumn::Magick::ImageList
Hi,
I have been using RMagick and File Column in my app together without a
problem, but when I tried to add in some new functionality in my model
where I use file_column, I got the error in the subject line. The
offending line in my code is:
image = Magick::ImageList.new(path_to_image)
Has anybody ever seen this problem when using the two libraries
together? I have tried adding in a require

using file_column. This was working great, for about an hour, but all of
the sudden I began to get the following error (only when i attempt to
resize).

file_column: patched for imagemagick and validation
Hi all,
I patched file_column to add imagemagick transformations of uploaded
content. I added an options hash, and it takes the :magick and
:format keys. :magick is a string of imagemagick command line options
for convert (Reference:
http://www.imagemagick.org/script/convert.php). Format is an optional
extension for the finished image. If Imagemagick recognizes the
extension, then it will

file_column imagemagick strangeness
Hi,
I''m using the basic magick features of file_column,
and while files are uploading fine without the magick options, as soon as I do something like
:magick => { :size => "400x600" }
I get an ''invalid file'' error.
Further investigation reveals that the file is in fact invalid because something somewhere is truncating the file path:

file_column - how to test for empty column?
I am using the excellent file_column, but have run into an issue.
I am wanting the user to be able to *not* upload an image if they so
choose. Then I am trying to determine if that column is empty or not,
and display a generic image if that column is empty.
I have tried both of the following code blocks:

How do I validate using associated objects?
This doesn''t make any sense to me anymore. I have an Upload that
belongs_to a Comment. Within my Upload model I expect to be able to
access the associated comment with comment.foo. I can only seem to do

validation and updating the database, because when I try to access
