I am a newbie to Rails and i am trying the attachment\_fu plugin. I am  
referring to the post from the url  
[http://clarkware.com/cgi/blosxom/2007/02/24](http://clarkware.com/cgi/blosxom/2007/02/24)

When i try to upload an image i am getting the below error. I am using  
RMagick. Instead of max\_size, i am using size for the attachment  
options in the model.

undefined method `include?’ for 512000:Fixnum
