Question

我是Rails的新手。

如何在json中为方法添加分页？

我有一个show方法如下：

 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

我想分页问题包含在questions.to_json中。我该怎么做？

谢谢！

你只需要添加gem，will_paginate ref：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

添加分页以在json响应中包含方法
