ruby on rails- Order results by two columns

Question

i've got an article table (model Article) that i want to order by two boolean columns (:foreground, :on_evidence) for show some results in a view

in the controller of the view in the action index:

class ShowController < ApplicationController
  def index
    @articles = Article.where("published = true ").order('foreground, on_evidence')
  end
end

this method is wrong...how can i do for this trouble?

Answer 1

Ok i've found the solution simply i've changed the find query:

class ShowController < ApplicationController
  def index
    @articles = Article.where('published = true').order(foreground: :desc)
  end
end
