Hi,

I have a photos model that has\_many comments. When the photo is saved,  
it builds the comments into a string that is indexed.

When the comments are saved, it needs to re-index the comments from the  
photo model. The way I do it is by calling self.photo.save on the  
after\_save method of the comments model.

This seems botchy, is there a better way?

class Photo \< ActiveRecord::Base

has\_many :comments

acts\_as\_ferret :fields =\> [:title, :photo\_comments], :remote =\> true

def photo\_comments  
comments.collect{|c| c.comment}.join(’ ')  
end  
end

class Comment \< ActiveRecord::Base  
belongs\_to :account, :counter\_cache =\> true  
belongs\_to :photo, :counter\_cache =\> true

validates\_presence\_of :comment

def after\_save  
self.photo.save  
end

end

Thanks,

Tim
