Question

在发布此问题之前，我在这里尝试了类似问题的解决方案：
will_paginate function not rendering page links

而不是＆lt; - 1 2 3 ... N - ＆gt;，我看到消息“获取更多产品......”。

//控制器
1. @posts是ActiveRecord :: Relation
2. 6记录结果，所以期待3页

@posts = User.joins(entries: [{storage: :vote}, :category])
             .where("votes.count > ?", 0)
             .select("users.username AS username,
                       storages.id AS storage_id,
                       storages.title AS title, 
                       storages.content AS content, 
                       votes.count AS votes, 
                       categories.category_name AS category_name")
             .order("votes.count DESC")

@posts = @posts.page(params[:page]).per_page(2)

//查看

<% @posts.each do |post| %>
   ...
   ...
<%end%>
<%= will_paginate @posts %>

http://localhost:3000/?page=1我看到“获取更多产品......” 对于http://localhost:3000/?page=2也“获取更多产品......”
但对于http://localhost:3000/?page=3我看到了上一页1 2 3下一页→。为什么只在最后一页进行分页？

我正在使用RoR 4.0.0

Gemfile: gem 'will_paginate', '~> 3.0.5'

Answer 1

应该是

@posts = @ posts.paginate（params [：page]，per_page：2）
