如何实现Ajax分页与will_paginate gem是项目 [英] How to Implement ajax pagination with will_paginate gem

问题描述

我使用 will_paginate 宝石在我的 ROR 的项目，以显示在页面的记录。

I am using will_paginate gem in my ROR project to show the records in pages.

我想下一个页面，而无需使用 AJAX 。

I want the next page to be loaded without reloading the whole page using ajax.

我发现在网络上的一些例子，但他们不为我工作。

I found some examples on the net but they don't work for me.

如何做到这一点？

推荐答案

与下面的内容创建一个新的辅助（如应用程序/佣工/ will_paginate_helper.rb。）：

Create a new helper (ex. app/helpers/will_paginate_helper.rb) with the following content:

module WillPaginateHelper
  class WillPaginateJSLinkRenderer < 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

      @template.link_to(target, attributes.merge(remote: true)) do
        text.to_s.html_safe
      end
    end
  end

  def js_will_paginate(collection, options = {})
    will_paginate(collection, options.merge(:renderer => WillPaginateHelper::WillPaginateJSLinkRenderer))
  end
end

然后在您的视图中使用此标记为Ajax分页：

Then in your view use this tag for ajax pagination:

<%= js_will_paginate @recipes %>

记住，分页链接包括URL的现有PARAMS，您可以排除这些如​​下图所示。这是标准的将分页功能：

Remember that the pagination links will include existing params of the url, you can exclude these as shown below. This is standard will paginate functionality:

<%= js_will_paginate @recipes, :params => { :my_excluded_param => nil } %>

希望能解决你的问题。
