与kaminari和mongoid的分页

Question

我有这个问题

＆＃13;

＆＃13;

undefined method `total_pages' for #<Mongoid::Criteria:0x00000002651d80>

＆＃13;

＆＃13;

＆＃13;

的Controler

＆＃13;

＆＃13;

@services = Service.paginate(:page => params[:page], :per_page => 3)

＆＃13;

＆＃13;

＆＃13;

视图

＆＃13;

＆＃13;

<% paginate @services %>

＆＃13;

＆＃13;

＆＃13;

mongo不会返回对象。

Answer 1

的Controler

＆＃13;

＆＃13;

class	ServicesController < ApplicationController
	def index
		#@services = Service.order(name: :asc)
		@organs = Admin::Organ.all
		@services = Service.paginate(:page => params[:page], :per_page => 3)
	
	end
end

＆＃13;

＆＃13;

＆＃13;

＆＃13;

＆＃13;

<% pagination @services %>

＆＃13;

＆＃13;

＆＃13; ERRO

＆＃13;

＆＃13;

undefined method `total_pages' for #<Mongoid::Criteria:0x00000002651d80>

＆＃13;

＆＃13;

＆＃13;

是这个

Answer 2

在kaminari，你必须 使用以下语法

 Service.page(params[:page].to_i).per(3)

而不是

 Service.paginate(:page => params[:page], :per_page => 3)

这是will_paginate

的语法
