在json响应中添加分页以包含方法

Question

我是Rails的新手。

如何将分页添加到json中的方法？

我有如下一个show方法：

def show 
    respond_to do |format| 
    format.html { redirect_to @question, notice: 'Y'} 
    format.json {render json: @question.to_json(:include => { :responses => {:methods => [:description, :file_url] } })} 
    end 
end 

我想分页列入questions.to_json响应。我怎么做？

谢谢！

你只需要添加宝石，will_paginate裁判：https://github.com/mislav/will_paginate

def show 
    @questions = Question.all.paginate(page: params[:page], per_page: 4) 
    respond_to do |format| 
    format.html { redirect_to @question, notice: 'Y'} 
    format.json {render json: @questions.to_json(:include => { :responses => {:methods => [:description, :file_url] } })} 
    end 
end
