Question

我有我的控制者:

class FormulariosController < ApplicationController
    cache_sweeper :campanha_sweeper, :only => [:show]

    # actions
结束

我试图在服饰中建立一个叫作/扫清器的目录,并做 t工作,我尝试在模型中设置一个/Cache 夹(如用这个例子算出的博客),并做工。

我 looks切地看着这一点:

class CampanhaSweeper < ActionController::Caching::Sweeper
  observe Campanha

  def after_update(campanha)
    expire_cache_for(campanha)
  结束

  private
  def expire_cache_for(campanha)
    expire_page(:controller =>  formularios , :action =>  show )

    ap "Expired cache for formularios#show in formulariosweeper"
  结束

结束

我在努力启用服务器时,先是:

Why didn t it work? Also, is there any way to expire cache of only a view(of how it s r结束ered). I m generating views on the fly and it would be very useful if I could expire the cache of a view that is located at say, views/formularios/a.html.rb

如果想知道我做些什么,那就简单了。我提出形式的看法,如果我想更新这种观点(或守则)和一米生产的话,那么,由于砍刀,我不得不人工重新制作这种表格。

感谢。
