Using will_paginate with Rails API application

It is very simple to implement will_paginate with Rails API application. We just have to pass page number and per page item. Per page item can be static also.

@posts = Post.paginate :page => params[:page]
render :json => { 

   :current_page => @posts.current_page,

   :per_page => @posts.per_page,

   :total_entries => @posts.total_entries,   

   :total_pages => @posts.total_pages,

   :entries => @posts 

 }
