Kimchoy's method worked perfectly for me, but was spitting out escaped html entities into my layout, so I made the following change (plus a small change to the markup and hyphenation for my purposes):

  def page_entries_info(collection, options = {})
    collection_name = options[:collection_name] || (collection.empty?? 'entry' : collection.first.class.name.underscore.sub('_', ' '))

    if collection.num_pages < 2
      case collection.size
      when 0; info = "No #{collection_name.pluralize} found"
      when 1; info = "Displaying <strong>1</strong> #{collection_name}"
      else;   info = "Displaying <strong>all #{collection.size}</strong> #{collection_name.pluralize}"
      end
    else
      info = %{Displaying #{collection_name.pluralize} <strong>%d&ndash;%d</strong> of <strong>%d</strong> in total}% [
        collection.offset_value + 1,
        collection.offset_value + collection.length,
        collection.total_count
      ]
    end
    info.html_safe
  end

#page_entries_info feature has been added a long time ago so I'm closing this issue. Thanks guys for the suggestion!

I stumbled across the same issue; did not find anything in the source, so I threw together my own helper method to get somewhat similar results. The method is far from complete, and not terribly clean, but you are welcome to use it to work from.

def page_entries_info(collection)
  content_tag :div, :class => "page_info" do
    collection_name = collection.klass.name.downcase.pluralize
    if collection.count > 0
      "Displaying #{collection_name} #{collection.offset_value + 1} - #{collection.offset_value + collection.length} of #{collection.count} in total"
    end
  end
end

That said, given kaminari's focus as an engine with overridable views, this type of thing would be better served with a view along the lines of what paginate is doing, yeah?

Thanks for this helper, it helps! :)

Btw,

collection.count

always returned 0, so I changed it to:

collection.klass.count

i stumbled upon the same issue too, so this is what i did (reusing will_paginate method)

def page_entries_info(collection, options = {})
    collection_name = options[:collection_name] || (collection.empty?? 'entry' : collection.first.class.name.underscore.sub('_', ' '))

    if collection.num_pages < 2
      case collection.size
        when 0; "No #{collection_name.pluralize} found"
        when 1; "Displaying <strong>1</strong> #{collection_name}"
        else;   "Displaying <b>all #{collection.size}</b> #{collection_name.pluralize}"
      end
    else
      %{Displaying #{collection_name.pluralize} <strong>%d&nbsp;-&nbsp;%d</strong> of <strong>%d</strong> in total}% [
      collection.offset_value + 1,
      collection.offset_value + collection.length,
      collection.total_count
      ]
    end
  end

oh yeah. good idea cobychapple, saves the trouble of doing the html_safe on the views.

For using this with Sunspot search results you need to tweak it slightly as offset_value is not defined

page_entries_info(@search.results, {:collection_name => 'result'})

def page_entries_info(collection, options = {})
  collection_name = options[:collection_name] || (collection.empty?? 'entry' : collection.first.class.name.underscore.sub('_', ' '))

  if collection.num_pages < 2
    case collection.size
    when 0; info = "No #{collection_name.pluralize} found"
    when 1; info = "Displaying <strong>1</strong> #{collection_name}"
    else;   info = "Displaying <strong>all #{collection.size}</strong> #{collection_name.pluralize}"
    end
  else
    offset_value = collection.per_page * (collection.current_page - 1)

    info = %{Displaying #{collection_name.pluralize} <strong>%d&ndash;%d</strong> of <strong>%d</strong> in total}% [
      offset_value + 1,
      offset_value + collection.length,
      collection.total_count
    ]
  end
  info.html_safe
end
