[英]ruby on rails 3.1 fragment caching
I have an app and I'd like to cache some parts of the page, and I have been reading a lot about the ways to do this. 我有一个应用程序,我想缓存页面的某些部分,我已经阅读了很多关于如何做到这一点的方法。
I understand that fragment caching is the best way to do it on my project, but I can´t find a simple example to learn how to implement this. 我知道片段缓存是在我的项目中执行它的最佳方式,但我找不到一个简单的例子来学习如何实现它。
I would like to use the fragment cache with autoexpire . 我想将片段缓存与autoexpire一起使用。
<% cache(:action => 'recent', :action_suffix => 'all_products') do %>
All available products:
<% Product.all.each do |p| %>
<%= link_to p.name, product_url(p) %>
<% end %>
<% end %>
Where do I set the autoexpire? 我在哪里设置autoexpire? any examples around?
有什么例子吗? how can I do this?
我怎样才能做到这一点?
In your product model you can do something like this 在您的产品型号中,您可以执行以下操作
after_save :expire_caches
after_destroy :expire_caches
# can't do this in a sweeper since there isn't a controller involved
def expire_caches
ActionController::Base.cache_store.delete_matched(%r{product\?for=\d+&fragment=products})
