Returning multilpe values from model method in view

Question

I have the following method in my model:

  def self.set_bad_recommedation_size(rating_set)
    bad = Rating.where(rating_set: rating_set).where(label: 'Bad').count
    total = Rating.where(rating_set: rating_set).count
    percentage_bad = (bad.to_f/total.to_f * 100)
    return bad, total, percentage_bad
  end

How do I call the variable bad, total, percentage_bad in my view. What I want:

<%= "#{Model.set_bad_recommedation_size(rating_set).bad}/#{Model.set_bad_recommedation_size(rating_set).total"%>

Answer 1

You're better off doing:

<% bad, total, percentage_bad = Model.set_bad_recommedation_size(rating_set) %>
<%= "#{bad}/#{total}" %>

That way you're not calling the method multiple times.
