will_paginate 从 1 开始下一页计数，并带有索引 [英] will_paginate starts next page count from 1 with indexing

问题描述

我有一个帖子索引页面，它是这样的:

I have an indexed page of posts and it goes like:

<% @posts.each_with_index do |post, index| %>
   //do some rendering
<% end %>
<%= will_paginate @posts %>

在我的控制器中，我有以下内容:

While in my controller i have the following:

def index
    @posts = Post.paginate(:page => params[:page], :per_page => 15)
end

第一页编号最多为 15，但当我进入第二页时，索引计数回到 1.我希望它从 15 开始.谢谢x

The first page numbering counts up to 15 but when i proceed to page two the index count goes back to 1. I want it to proceed from 15 onwards. Thankx

推荐答案

不得不浏览 will_paginate 代码才能找到解决方案.在配方模型中，我添加了此方法.

Had to browse through the will_paginate code to come up with a solution. In recipe model i added this method.

def offset(page)
    per_page = 15
    @off_set = WillPaginate::PageNumber(page).to_offset(per_page).to_i
end

在我的控制器中，我添加了:

While in my controller i added:

def index
     @page = params[:page]
end

最后在我看来我添加了这个:

Finally in my view i added this:

<%= index + recipe.offset(@page) + 1 %>
