Hi -

I have been using attachment\_fu w/o issue - but updated my rails and  
now get a callback error. Has anyone encountered this? Or solved it  
easily?

Info: Rails 2.1.0  
Error: “undefined method `callbacks\_for’ for #BlogImage:0xb6aa20c4”

Thanks!

I’m not having an issue. But you might because you have a slightly older  
version. Go fetch the latest attachment\_fu plugin, as there’s some fixes  
for  
Rails callbacks in there.
