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| -%\>

Upload An Icon \<%= f.file\_field :uploaded\_data %\>

\<%= submit\_tag 'Create' %\>

\<% end -%\>

Any suggestions would be greatly appreciated.

Thanks,
