Question

I need to calculate what page a comment is on so I can create a direct link to it. I’m using kaminari pagination with monogid. On kaminari’s wiki they have a solution on how to do it with activerecord but I’m not sure the best way to translate that into mongoid.

Answer 1

Here is a stripped down version that I ended up coming up with.

def page_num
  number_before = self.class.where(recipe_id: recipe.id).gte(created_at: created_at).count.to_f
  number_on_page = self.class.default_per_page
  (number_before / number_on_page).ceil
end
