Я использую will_paginate, чтобы разбить на страницы результаты поиска по геокитам. Код работает, однако, при просмотре журнала он удваивает запрос geokit при использовании следующего вызова will_paginate:
@posts = Post.paginate :page => params[:page], :per_page => 1,
:origin => @search, :within => @miles, :include => :user
Это исходный вызов без разбиения на страницы, который работает как ожидалось (один запрос):
@posts = Post.find(:all, :origin => @search, :within => @miles, :include => :user)
Ниже приведен вывод журнала при использовании первого вызова will_paginate:

Rendering template within layouts/application
Как видите, запросы KML / XML и SQL удваиваются. Есть идеи, что происходит и как я могу это исправить? Спасибо!
