I'm trying to use will paginate with ajax, but I don't show the will_paginate buttons... instead I use a see more button, that makes an Ajax request and append the results to the page.
what I'm trying to do is disable this see more button if I hit the last page of records!!
Any idea how to know that the current page is the last page??
@collection.total_pages == @collection.current_page
Accessing the @collection.total_pages method will give you the total number of pages currently being returned. You can use this to evaluate against your active page using the @collection.current_page method. This is still applicable if you're reloading your collection on each expansion.
The implementation will be to use the AJAX call to replace the HTML content if this evaluation is true.
You can use next_page condition
@collection.next_page.present?
