What about when we are trying to remove something from the cache?
I am accessing an action /user/show/id/1; in theory, this falls under
the first example, i.e. cache is enabled (anyway, I _see_ that it is
enabled because data doesn't update when I update it). I want to add a
remove() call to the cache on update.
I tried the following as per the manual:
- in my showSuccess.php:
<? if (!cache("user".$user->getUserid(), 3600)): ?>
blah blah
<? cache_save(); endif; ?>
- in my actions.class.php, in the executeUpdate():
$cacheManager = $this->getContext()->getViewCacheManager();
$cacheManager->remove("@sf_cache_partial?
module=user&action=show&sf_cache_key=user".$this-
>getRequestParameter('id'));
This does not remove the cache (just for fun I tried removing the
$user->getUserid() and $this->getrequest...etc, i.e. leaving a single
cache entry for the whole world, but that *still* didn't remove the
cache).
I suspect this is related to the GET parameters, perhaps Symfony
assigns another key to this?
Any help appreciated!
