带有引导分页的 Draper - 未定义的方法“total_pages”

Question

我正在使用 Draper 来装饰我的视图并从中移除一些逻辑，但我正在努力解决这个问题 - 如何使用 Bootstrap Pagination (will_paginate) 设置 Draper？

默认情况下我有这个：

delegate_all

从 Draper 文档中，我尝试添加以下内容：

delegate :current_page, :per_page, :offset, :total_entries, :total_pages

但是在视图中调用分页时仍然会返回错误。 我的控制器这样定义装饰和分页：

@matches = Match.all.paginate(:per_page => 10, :page => params[:page]).decorate

我的看法：

<%= will_paginate @matches, renderer: BootstrapPagination::Rails %>

更新：

class ApplicationDecorator < Draper::Decorator
  def self.collection_decorator_class
    PaginatingDecorator
  end
end


class PaginatingDecorator < Draper::Decorator
  # support for will_paginate
  delegate :current_page, :total_entries, :total_pages, :per_page, :offset
end


class PlayerDecorator < ApplicationDecorator
  delegate_all
  decorates_association :matches


class MatchDecorator < ApplicationDecorator
  delegate_all
  decorates_association :players
