如何在rails中使用will_paginate和ransack

Question

我正在使用ransack进行搜索，现在我想在我的rails应用程序中实现分页。所以我使用了will_paginate gem。我面临的问题是，我无法弄清楚如何将paginate放入当前控制器代码中，因为它已根据查询获取结果。

这里是我的控制器代码

def search 
if params[:search].present? && params[:search].strip != "" 
    session[:loc_search] = params[:search] 
end 
arrResult = Array.new 
if session[:loc_search] && session[:loc_search] != "" 
    @rooms_address = Room.where(active: true).near(session[:loc_search], 5, order: 'distance') 
else 
    @rooms_address = Room.where(active: true).all 
end 

@search = @rooms_address.ransack(params[:q]) 
@rooms = @search.result 

@arrRooms = @rooms.to_a 

有人能告诉我如何把分页这里？

你分页搜索的结果，所以ransack后更新。 像@rooms = @search.result.paginate(page: params[:page], per_page: params[:per_page])应该工作。
