I'm building an index page where I need to display results which have a date, ordered chronologically (from the earliest date to the newest one), but I need to always show the last page by default.
I can't use a DESC order for the date because it would defeat the whole purpose of what I need this for =(.
TL;DR: I need to show a paginated log list, sorted by date ascending, but starting in the last page. Is this possible with will_paginate? Thanks!
This is the solution I finally arrived to:
if params[:page] @collection = @q.result(distinct: true).paginate(:page => params[:page], :per_page => 30) else last_page = @q.result(distinct: true).paginate(:page => params[:page], :per_page => 30).total_pages @collection = @q.result(distinct: true).paginate(:page => last_page, :per_page => 30) end
It's not fancy, it needs some refactoring and perhaps can use memoization to avoid calling the
paginate method twice, but hey it works. If you are trying to access a page directly, it is rendered as usual, but if you don't specify a page, you are taken to the last page by default.
