How to export data in json/csv without pagination

I'm using active_admin for one of my projects, and I have some tables with a lot of data (+100,000 records).

Its fine to paginete to browse the data, but when I want to export the data (so I can do custom match in excel), and I try to export in xml, it just export the current records of the page, instead of exporting the total records on the filtering.

module ActiveAdmin
  class ResourceController
    module Collection
      module Pagination
        def max_csv_records
          1_000_000
        end
      end
    end
  end
end

but that won't work for xml/json, any ideas how to solve that?

Thx

This might help for some versions of active admin:

module ActiveAdmin::ResourceController::DataAccess
  protected

  def apply_pagination_with_csv(chain)
    return chain if request.format == 'text/csv'
    apply_pagination_without_csv(chain)
  end

  alias_method_chain :apply_pagination, :csv
end

To figure out if the patch works you should pick into the installed gem this file

I ended up doing another monkey patch, there may be a better way but this one works

module ActiveAdmin
  class ResourceController
    module Collection
      module Pagination
        def per_page
          return 1_000_000 if %w(text/csv application/xml application/json).include?(request.format)

          return max_per_page if active_admin_config.paginate == false

          @per_page || active_admin_config.per_page
        end
      end
    end
  end
endend
