Question

I have a blogging application in which User has_many posts. I am using pagination with Booststrap. How can I make the partial_count method work with pagination? Currently, the count resets on every page instead of carrying over across pages.

posts_controller.rb

def index
  @posts = Post.order("created_at desc").paginate(page: params[:page], :per_page => 12)
end

views/posts/index.html.erb

<%= render @posts %>
<%= will_paginate %>

views/posts/_post.html.erb

<%= post_counter +1%>
<%= post.name %>

The counter works fine on the first page. However, all subsequent pages also start with “1”. How can I make subsequent pages start with (number of pages * 12 + 1) instead?

Thanks for your feedback!

Use @posts.offset to get the proper counter initialisation.
