Subject: Rails attachment_fu db_file upload issue.

I've recently added attachment_fu to my applicatons, and it works
without reporting any errors.  Works fine in :file_system mode, but
not in :db_file mode.  It seems to upload only about 45 bytes of data
instead of the entire image, image download works fine when I manually
put the data in the database.

  I've created an Icon model that has the following has_attachment
settings

 has_attachment  :content_type => :image,
                 :storage => :db_file,
                 :max_size => 1.megabyte,
                 :resize => '75x75>',
                 :processor => 'MiniMagick'

 validates_as_attachment

I've removed the resize and processor statements and I'm fairly
confident that the issue is not related to image processing.  And
again the upload works to storage type :file_system.  My controller
create method looks like this:

 def create
   @icon = Icon.new(params[:icon])
   if @icon.save
     flash[:notice] = 'Icon was successfully created.'
     redirect_to :action => 'show', :id => @icon
   else
     render :action => :new
   end
 end


And my 'new' view looks like:


<%= error_messages_for :icon %>

<% form_for(:icon, :url => {:action => 'create'},
                     :html => { :multipart => true }) do |f| -%>
 <p>
   <label for="icon">Upload An Icon</label>
   <%= f.file_field :uploaded_data %>
 </p>
 <p>
   <%= submit_tag 'Create' %>
 </p>
<% end -%>

Any suggestions would be greatly appreciated.

Thanks,
