Question

我正在使用带有Ruby on Rails的Will paginate gem（4.2）并呈现我正在使用Ajax的页面。我正在使用will paginate helper来做到这一点。并且正在正确地请求页面并接收响应但不呈现下一个HTML页面。谁能告诉我它里面缺少什么？

使用：

<%= ajax_will_paginate @itmes, :params => { :my_excluded_param => nil } %>

制作分页链接。

这是我的分页助手：

module WillPaginateHelper

  class WillPaginateAjaxLinkRenderer < WillPaginate::ActionView::LinkRenderer

    def prepare(collection, options, template)

      options[:params] ||= {}

      options[:params]["_"] = nil

      super(collection, options, template)

    end

    protected

    def link(text, target, attributes = {})

      if target.is_a? Fixnum

        attributes[:rel] = rel_value(target)

        target = url(target)

      end

      ajax_call = "$.ajax({url: '#{target}', dataType: 'script'});"

      @template.link_to_function(text.to_s.html_safe, ajax_call, attributes)

    end

  end

  def ajax_will_paginate(collection, options = {})

    will_paginate(collection, options.merge(:renderer => WillPaginateHelper::WillPaginateAjaxLinkRenderer))

  end

end

我的控制器功能是：

  def index

    @items = Item.paginate(:per_page => 5, :page => params[:page])

  end

我添加了代码index.js.erb

现在终端日志是：现在终端日志是：

您没有创建要在ajax请求上呈现的名为items的部分文件。请尝试以下。

应用程序/控制器/ items_controller.rb

def index
  @items = Item.paginate(:per_page => 5, :page => params[:page])
end

视图/项目/ index.html.erb

<div class = "sort_paginate_ajax"><%= render 'items' %></div>

视图/项目/ _items.html.erb

<% @items.each do |item| %>
# your code
 <%= item.name %>
<% end %>
<%= ajax_will_paginate @items %>

视图/项目/ index.js.erb的

$('.sort_paginate_ajax').html("<%= escape_javascript(render("items"))%>")
