Hi,

I’m having some issues with deploying my app to my host server  
(Dimension Servers). I froze the gems (Instant Rails 1.2.3) on my  
local server and have the app running flawlessly boh on my machine and  
on a few other development machines. After deploying to the host, I  
get the following error on one of my views. Note: I’m using  
attachment\_fu, which I don’t imagine could have anything to do with  
this…

Any help would be much appreciated!

ActionView::TemplateError (Expected /home/yourhome/public\_html/beta/  
current/config/…/app/models/product\_image.rb to define ProductImage)  
on line #2 of app/views/products/show.rhtml:

## \<%= @product.name %\>

# Generate URL for product images  
return p.product\_image.nil? ? image\_tag("/noimage.jpg") :  
image\_tag(p.product\_image.public\_filename)  
end
