Question

Using Ajax pagination via the will_paginate gem I’m having an issue rendering my collection since adding the pagination: I cannot display the indexes properly.

For example, in my view, I render the collection:

<%= render @songs %>

In the song partial, I have the following to help make the list look pretty:

<%= @songs.index(song) + 1 %>

My pagination is twitter-style, in that every time someone clicks “more”, it shoots out 5 more songs. The issue is the index of the collection is always 0-4 as my collection is limited to 5 via the pagination arguments.

What should I do to get these indexes working? Should I be getting two collections in my controller, one for pagination and one that is not simply for rendering the index?

Thanks

Answer 1

(params[:page].to_i * @songs_per_page) + @songs.index(song) + 1
