According to:
http://book.cakephp.org/2.0/en/core-libraries/caching.html#using-groups
"Groups are shared across all cache configs using the same engine and same
prefix. If you are using groups and what to take advantage of group
deletion, choose a common prefix for all your configs."
So this seems that you can use cleargroup() to clear a specified group
across all cache configs. But then why does cleargroup() take a config as
a parameter which defaults to "default"?
How is it going to clear the specified group across all configs if it
defaults to the "default" config? Am I supposed to call it multiple times
specifying a different cache config each time? Seems to defeat the purpose
of groups.
ex:
Cache::config('short', array(
'engine' => 'File',
'duration'=> 60,
'serialize' => true,
'prefix' => 'CA',
'groups' => array('posts')
));
Cache::config('med', array(
'engine' => 'File',
'duration'=> 180,
'serialize' => true,
'prefix' => 'CA',
'groups' => array('posts')
));
Cache::config('long', array(
'engine' => 'File',
'duration'=> 300,
'serialize' => true,
'prefix' => 'CA',
'groups' => array('posts')
));
So for the above, according to the docs and api
Cache::cleargroup('posts')
would clear "posts" group but only if using the 'default' config.
Am I missing something?
