How might I use file_column for incoming email attachments?
I'm writing a 'Mailman' model that catches emails sent to my
application (kind of like backpack, I think). The trouble is that
I'd like to save image attachments in the same was that file_column
saves them--in fact, I'd really like to use a simple assignment like
photo.image = attachment to save the image in its proper place.
However, I'm getting the following error from the ImageMagick
extension of file_column:
"Image invalid image"
("image" is the name of the column, so that's why it seems to be
duplicated).
Does anyone know how to leverage file_column's fantastic simplicity
when dealing with this kind of incoming attachment?
Thanks,
Duane Johnson

I use a modified magick_file_column.rb that uses the command-line Imagemagick, because I'm not a fan of RMagick, so I can't say too much, but try breakpointing the first few lines of the magick_file_column.rb to see what that exception is coming from. -- Kyle Maxwell Chief Technologist E Factor Media // FN Interactive kyle@efactormedia.com 1-866-263-3261

Thanks for looking in to this a bit, Kyle. I think my question is more of an "I don't quite understand how file_column automatically handles IOString objects, why won't it handle a TMail::Attachment object?" I did find the error message that you pointed out, but I was a bit surprised at the size of the plugin as a whole. Quite an achievement! :) Any idea how I might trick or otherwise modify file_column in to accepting TMail::Attachment object assignment (e.g. I'd like to do this: User.new(:photo => attachment) where :photo is a file_column column and attachment is a TMail::Attachment object)?

If you pass an ordinary File, FileColumn::FileCompat is mixed in to provide this functionality. This happens in BaseUploadedFile.assign(). I don't know much about TMail::Attachment, but if its similar enough to File, you could replace the first line in BaseUploadedFile.assign(): #old if file.is_a? File #new if file.is_a?(File) || file.is_a?(TMail::Attachment) -- Kyle Maxwell Chief Technologist E Factor Media // FN Interactive kyle@efactormedia.com 1-866-263-3261
