I have two models:

testamonial  
photo (has\_attachement)

testamonial has\_one photo

The issue is when do this:  
@testamonial = Testamonial.find\_all\_by\_id(id)

I get “undefined method `photo’ for” in my browser?? BUT here is the  
big kicker…

If I do @testamonial = Testamonial.find(:first)

everything works fine and the image is show!.. (find :all works too  
when I loop through the objects.)

I tried @testamonial = Testamonial.find\_all\_by\_id(id, :include  
=\> :photo) That just gave me a bigger query and still no photo…

That returns an array of testamonials, not a single object as  
find :first does.

Are you sure the id matches the first record in the table?
