Mongoid Rails 4 sort by asc or desc order created_at

date, mongoid, ruby-on-rails-4, sorting

Solution

You can try this

def index
  @books = Book.order_by(created_at: :desc)
end

it works fine.

Problem

I have a rails 4 app using Mongoid. I want to do something basic is display the book model I have by descending order according to the field created_at in the index view. In the controller books_controller.rb: ``` def index @books = Book.order_by(:created_at.desc) end ``` This is not working. I also tried the following 2 that are not working: ``` @books = Book.find :all, :order => "created_at DESC" Book.find(:all, :order => "created_at DESC").each do |item| @books << item end ``` In the view i have something like this: ``` <% @books.each do |b| %> ... <% end %> ``` Thank you.
