Question

I’m attempting to render the will_paginate html on the server so I can transplant the entire pager (and some other data) via ajax .

I’ve been able to use

view_context.will_paginate(@posts)

to successfully render the pager in my controller for the ajax call.

Unfortunately, when I run that using format.json, all of my links include the .json format.

/posts.json?page=1
/posts.json?page=2

when they should really be

/posts?page=1

Ideas?

If your using the latest will_paginate gem then you can just create a custom link renderer like so

#
# lib/custom_link_renderer.rb
#
class CustomLinkRenderer < WillPaginate::ActionView::LinkRenderer
  protected
  def url(page)
    page = super.gsub(".json", "")
  end
end

Make sure you autoload your lib directory in your application.rb

config.autoload_paths += %W(#{config.root}/lib)

then you can render your pager like so

view_context.will_paginate(@posts, renderer: CustomLinkRenderer)

Hope this helps and happy coding
