Hi all. I’m trying to get gravtastic working at my comments model, so  
I’m  
doing this:

class Comment \< ActiveRecord::Base  
validates\_presence\_of :commentary

belongs\_to :commentary, :polymorphic =\> true

attr\_accessor :anon

is\_gravtastic :rating =\> ‘R’,  
:size =\> 40 ,  
:default =\> “/images/no\_gravatar.png”  
end

My doubt is: using comment.gravatar\_url gives me the following:

[http://gravatar.com/avatar/HASH.png?d=%2Fimages%2Fno\_gravatar.png&amp;r=R&amp;s=40](http://gravatar.com/avatar/HASH.png?d=%2Fimages%2Fno_gravatar.png&amp;r=R&amp;s=40)

And it doesn’t renders my image correctly. How can I get my full  
application  
URL as [http://my.domain.tld/app/images/no\_gravatar.png](http://my.domain.tld/app/images/no_gravatar.png) ?

## Thanks,

## Davi V.

I’m using Mongrel as development server, but I’ll deploy it to Apache  
+  
Passenger.

I’m trying to use request\_uri, but no success.

Any kind of tips, please?

## Best regards,
