Paginate by most recent post with kaminari

Question

I'm using the rails gem kaminari (https://github.com/amatsuda/kaminari) in order to paginate my posts database. Currently I have the code @posts = Post.order('id').page(params[:page]).per(5) in my controller, but this orders the pages from earliest to most recent. How do I reverse this and order from most recent to earliest?

Answer 1

in your model you can do:

default_scope order("created_at DESC")  

or

default_scope order("created_at ASC")  

Answer 2

def index
    @all = Model.all
    @all = Model.order(sort_column + " " + sort_direction).paginate(:per_page => 5, :page => params[:page])
end

def sort_column
    Model.column_names.include?(params[:sort]) ? params[:sort] : "updated_at"
end

def sort_direction
    %w[asc desc].include?(params[:direction]) ? params[:direction] : "DESC/ASC"
end
