推荐答案

另一个选项是您可以在 ApplicationHelper 中定义您的 page_entries_info() 方法并像往常一样使用它.如果您知道不需要覆盖边缘情况(如我的情况)，这将为您提供更大的灵活性，甚至可以更加清洁和高效.您可以参考原始方法定义这里 看看有什么所有你需要实施.以下代码将运行您的大部分问题！

Another option is you can define your page_entries_info() method in your ApplicationHelper and use it as you normally would. This would give you more flexibility and can even be more cleaner and efficient if you know that you dont need to cover the edge cases (as in my case). You can refer the original method definition here and see what all you need to implement. Following code would run for most part of your problem!

def page_entries_info(collection, options = {})
  entry_name = options[:entry_name] || (collection.empty?? 'item' :
      collection.first.class.name.split('::').last.titleize)
  if collection.total_pages < 2
    case collection.size
    when 0; "No #{entry_name.pluralize} found"
    else; "Displaying all #{entry_name.pluralize}"
    end
  else
    %{Displaying %d - %d of %d #{entry_name.pluralize}} % [
      collection.offset + 1,
      collection.offset + collection.length,
      collection.total_entries
    ]
  end
end
