Average rating and total number of ratings together

[ghost]

Hi,

I am using activerecord_reputation_system gem to rate something, let's call it model X. In app/models/x.rb I have

has_reputation :rating, source: :user, aggregated_by: :average

This lets me view the average rating.

My question: how can I view both average rating and total number of votes for model X? One way would be to add to app/models/x.rb:

has_reputation :rating, source: :user, aggregated_by: :average
has_reputation :reviews, source: :user, aggregated_by: :sum

and in the controller have:

value = params[:rating]
@x = X.find(params[:id])
if X.where(id: params[:id]).evaluated_by(:reviews, current_user).blank?
  @x.add_or_update_evluation(:reviews, 1, current_user)
end
@x.add_or_update_evaluation(:rating, value, current_user)

Is this the best way to do it or is there a better way?

Thanks a lot.

It may not be built into the system, but you can probably do a custom query against ReputationSystem::Evaluation.all.count replace all with your own filter. Your controller is essentially storing an extra evaluation for each one, which is duplicating data.
