This line in development.rb ensures that caching is not happening.

<pre><code>config.action_controller.perform_caching = false
</code></pre>

You can clear the Rails cache with 

<pre><code>Rails.cache.clear
</code></pre>

That said - I am not convinced this is a caching issue. Are you making changes to the page and not seeing them reflected? You aren't perhaps looking at the live version of that page? I have done that once (blush).

Update: 

You can call that command from in the console. 
Are you sure you are running the application in development?

The only alternative is that the page that you are trying to render isn't the page that is being rendered. 

If you watch the server output you should be able to see the render command when the page is rendered similar to this:

<pre><code>Rendered shared_partials/_latest_featured_video (31.9ms)
Rendered shared_partials/_s_invite_friends (2.9ms)
Rendered layouts/_sidebar (2002.1ms)
Rendered layouts/_footer (2.8ms)
Rendered layouts/_busy_indicator (0.6ms)
</code></pre>

blocks|key|1085491|text|在/public中检查页面的静态版本，如果有则将其删除。当Rails+3.x缓存页面时，它会在您的公共文件夹中留下一个静态版本，并在用户访问您的站点时加载该版本。即使在清除缓存之后，这也会保留下来。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1085492|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Check for a static version of your page in /public and delete it if it's there. When Rails 3.x caches pages, it leaves a static version in your public folder and loads that when users hit your site. This will remain even after you clear your cache.

If you're doing <a href="http://guides.rubyonrails.org/caching_with_rails.html#fragment-caching" rel="nofollow">fragment caching</a>, you can manually break the cache by updating your cache key, like so:

<h3>Version #1</h3>

<pre><code>&lt;% cache ['cool_name_for_cache_key', 'v1'] do %&gt;
</code></pre>

<h3>Version #2</h3>

<pre><code>&lt;% cache ['cool_name_for_cache_key', 'v2'] do %&gt;
</code></pre>

Or you can have the cache automatically reset based on the state of a non-static object, such as an ActiveRecord object, like so:

<pre><code>&lt;% cache @user_object do %&gt;
</code></pre>

With this ^ method, any time the user object is updated, the cache will automatically be reset.

I have a RoR application (ruby v1.8.7; rails v2.3.5) that is caching a page in the development environment. This wouldn't be so much of an issue, but the cached page's <code>a</code> elements are incorrect.

I haven't made any changes to the development.rb file and I haven't knowingly added any caching commands to the controllers.

I've tried clearing the browser's (Firefox 3.5 on OSX) cookie and page caches for this site (localhost). I've also restarted Mongrel. Nothing seems to help.

What am I missing?

我有一个在开发环境中缓存页面的RoR应用程序(Ruby1.8.7；rails 2.3.5)。这不是什么大问题，但是缓存页面的a元素是不正确的。我没有对development.rb文件做任何更改，也没有故意向控制器添加任何缓存命令。我已经尝试为这个站点(localhost)清除浏览器(OSX上的Firefox3.5)的c...
