雷成&Rails 分页 - 未定义的方法“current_page" [英] Kaminari & Rails pagination - undefined method `current_page'

问题描述

我搜索了又搜索，但没有解决我的问题.这是我的控制器:

I searched and searched, but nothing solved my problem. Here's my controller:

def show
    @topic = Topic.find(params[:id])
    @topic.posts = @topic.posts.page(params[:page]).per(2) # 2 for debugging
end

这个功能很好，因为主题视图减少到两个帖子.但是，当我将其添加到 show.html.erb 时:

That functions just fine, because the topic view is reduced to two posts. However, when I add this to show.html.erb:

<%= paginate @topic.posts %>

我收到了这个错误:

undefined method `current_page' for #<ActiveRecord::Relation:0x69041c9b2d58>

推荐答案

尝试:

def show
  @topic = Topic.find(params[:id])
  @posts = @topic.posts.page(params[:page]).per(2)
end

然后:

<%= paginate @posts %>
