As said above, in your model

def count_positive
evaluations.where( target_type: self.class, target_id: self.id, value: 1.0 ).count
end

def count_negative
evaluations.where( target_type: self.class, target_id: self.id, value: -1.0 ).count
end

then you can sum up both in your view

or

def count_total
evaluations.where( target_type: self.class, target_id: self.id, value: 1.0 ).count + evaluations.where( target_type: self.class, target_id: self.id, value: -1.0 ).count
end
