增加csv下载记录的限制

Question

I have more than 50K records in database but when I download a csv from active admin it gives me just 10K. I have googled the solutions and got that there is limit in the method named max_csv_records in

lib/active_admin/resource_controller/collection.rb

is there some way from which I can override this and increase the limit ?

Here's the gist I got https://gist.github.com/3177995 but can you guys tell me how can I use this code ? It would be much better if I can add something in active admin initializer

Answer 1

Just for future googlers. My fix (working for the current Master 1.0.0pre) is to add the following to config/initializers/active_admin.rb :

module ActiveAdmin
  class ResourceController
    module DataAccess
      # needed for current active admin master
      def max_per_page
        30_000
      end

      def per_page
        return 30_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

Replace the max as needed. This works for csv, xml and json downloads.
