    A call to Post.all will return an ActiveRecord::Relation, which will be loaded lazily by default. Calling Post.all.load will return an eagerly-loaded ActiveRecord::Relation. Finally, calling Post.all.to_a will return all records in an array.

    In your case you would do:

    Post.order('created_at DESC').limit(5).to_a
    

    which would return an array of the first 5 Posts, sorted by created_at in descending order.
