Uploading non image file using file column plugin

Rails
1

Hi

I am using file column plugin, this plugin uploads my image files
properly,
This plugin is integrated with RMagic and resizes my image files
properly. I
also want to upload doc, and excel files but that plugin does not
uploads
these files.

If any one can tell me how can i upload these files using file column
plugin

In controller i have this
def upload_file
if params[:user_picture]!=nil
params[:user_picture].each do
|id,
image|
@user_picture =
PostAttachments.new(image)
#@user_picture.user_id = @
current_user.id
@user_picture.posts_id = @
obj_post.id
@user_picture.save
end
end

In model i am using

class PostAttachments < ActiveRecord::Base
belongs_to :sections_posts
file_column :image, :magick => {
:versions => { “thumb” => “50x50”, “medium” => “170x107” }
}

end
