Rails - Dec 2005 - How do you detect if ''update'' save fails?

So I''m updating multiple model objects in one go with something like  
this in my controller:
=>	Photo.update(params[:photo].keys, params[:photo].values)

When the update fails due to validation errors, how do I detect it?  
The Rails API says:
"If the save fails under validations, the unsaved object is still  
returned."
So I can''t simply do this:
  =>	if Photo.update(params[:photo].keys, params[:photo].values)

Any suggestions?

photo=Photo.find params[:id]
unless photo.update_attributes params
   #error handling
end
