Re: Cache Help

[Reuben]

Oh, nice. My original reply was deleted.

Anyhoo, I might suggest that you only clear the cache for the particular 
Form(s) that were deleted or saved, using Cache::delete('getFormsById' . 
$id).  Although you may need to double check the event of multiple Forms 
being saved or deleted.  I think afterSave() and afterDelete() gets called 
for each entry, but you may want to check, just in case.

Re: Cache Help

[Eric Haskins]

Here is one of my models for dynamic forms. I hope it helps this is CakePHP 
2.x  so I clear cache afterSave (editing a forms structure) or afterDelete 
(selfexplanatory)  

class Forms extends AppModel {
public $primaryKey = 'id';

public function afterSave($created) {
parent::afterSave($created);
Cache::clear();
clearCache();
}

public function  afterDelete() {
parent::afterDelete();
Cache::clear();
clearCache();
}

public function getFormsById($id){
if (($form = Cache::read('getFormsById'.$id)) === false) {
$form = $this->find('first', array('conditions' => 
array('Forms.id'=>$id,'Forms.site_id'=> 
 Configure::read('Settings.site_id';
Cache::write('getFormsById'.$id, $form);
}
return $form;
}
}

Hope this helps.  I am new to Cake cache so if I am wrong someone please 
feel free to point it out

Re: Cache Help

[jmn2k1]

You must "invalidate" the cache, ie, delete the cache in a onSave callback.

Re: Cache Help

[Reuben]

I must admit, I've never cached model data. I figure the database engine 
will be better at caching data for quick (and often) retrieval in its 
buffers.  But I have done caching of results of web services, and the 
occasional view.

If you had to do caching of model data, then I would recommend clearing the 
relevant caches in the afterSave() and afterDelete() methods.  And even 
then, you should only need to clear the entry for the specific cached 
record.  You just need to make sure you an reproduce the key that you're 
using to save the data from the afterSave and afterDelete locations.

Re: Cache errors on Heroku with update to 2.3 but works fine on local?

[Brad Koch]

You're correct that Aspen and Bamboo are read only, but that doesn't apply
here because the Cedar stack (which all PHP apps run on) has a writeable
ephemeral file system [1].

Figured out my case though, CakePHP's default .gitignore [2] ignores the
tmp directory.  Therefore, since the entire tmp directory structure didn't
exist, it couldn't write the files it needed into the tmp directory.

So, when starting a new CakePHP app, make sure that you actually commit the
tmp directories into your repository.

Re: Cache errors on Heroku with update to 2.3 but works fine on local?

[Simon Males]

Issue is not CakePHP 2.3 specific. Heroku is a read only file system[1].

Though you can write to /tmp. So in core.php, when setting
Cache::config() update the value of the 'path' key to '/tmp'. I've
also shared my production Cache::config() settings[2].

Re: Cache errors on Heroku with update to 2.3 but works fine on local?

[Brad Koch]

Ran into the same problem with a new Heroku app of ours.  However, we've
been running the file cache on an older app for over a year and never had
problems.  (Both are on the cedar stack.)  Did you ever get to the bottom
of this?

I assume it has something to do with Heroku's philosophy of read-only
source code, but we should have the ephemeral file system so that shouldn't
matter.

Here's the thing - Heroku uses EC2, meaning that any files written are

Cake needs to know which engine and prefix you want to use for cleargroup().

You're probably missing ClearCache plugin - it allows to clear cache group 
even if it is specified in cache configurations with different cache 
engines and different prefixes.

Re: Cache FileEngine

[Sandreu]

Hi.
You're right, windows supports flock i read quickly flock description,
and I mixed up with the non blocant parameters.

Then it should be OK on windows.

why would it not work on windows? I didn't find such a hint on the

Re: Cache problem using CakePHP default File config on apache 1.3.x - server crashes

[luke BAKING barker]

hi Jon, thanks for your helpful reply.

I am not sure that it is performance, since the site is not really busy as 
yet, but maybe you have something. 

   I wonder if it is my statement to cache index action in my services 
controller for example


that is breaking things,

I might try just having caching on

but no actions. Then gradually add an action in 1 each few days.


My index action you see in actual fact takes an ID and so has about 40 
diffferent pages formed from it.


I put about 15 of these in like so in my controller:  


var $cacheAction = array(

 // 'index/'  => '1 day',

'index/1' => 172800, //2 days

'index/2' => 172800,

'index/3'  => 172800,


(I wonder if it is something like this that somehow forcing a high load on 
the server and then the cache file write is broken as you say.


I really don't know much at all about linux/server related things. 


Do you think another caching system might be a better route - or is File 
cache the most robust? Rather than Memcache etc.


thanks for your help and to people on IRC.


cheers


Luke

Are you able to increase headroom on the server? More ram/cpu perhaps,
if on a VPS upgrade to the next one up.

If you can, install htop and keep an eye to see what's using the most
processes, php, mysql etc.

What server optimisations do you have in place, APC etc? Have a read
of http://www.pseudocoder.com/blog/8-ways-to-speed-up-cakephp-apps

Sounds like cake is running out of juice during busy periods and
you're getting broken cache files as a consequence. I think your
options are to upgrade your hardware or optimise your application.
It's not really a cake bug, but growing pains, by the sounds of it.

Yes, that's right. Dispatcher checks if there's a cached file. If yes,
it loads up a View which in turn renders the cached version. No
controller required.

RE: Cache Confusion

[Krissy Masters]

Still no answers to my questions. No one has any insight?

If you cache the whole action ( $cacheAction) then is it to assume you don't
need to cache the query data or the view since the whole action is cached as
1 object? Does 1 cache take precedent over another. The actual action in the
controller is never hit (if already cached) so you would not need to cache
the query data in that action?

Function view ($id) {

//Read cache if empty get the data needed and cache the query data

$cache_data = Cache::read($cache_name);
if (empty($cache_data))
{
$dataModel = $this->Model->find('first');
Cache::write($cache_name, $dataModel, array('config' => 'File',
'duration' => 7200)); //if the action is cached do you need to cache this
data at all?
}
else
{
$dataModel = $cache_data;
}




}

Thanks to anyone who might have some insight!

Subject: Cache Confusion

Cache action, query and view/element. So how do you know which to use, when?

Basic example we use Post action => view,  id => 123

We cache the query data from the database so every time that Post is viewed
we simply read the cached data, fine easy enough delete that data cache on
update so we always pull new data.

***But***

If the action is cached do we need to cache the query data also? The view
holds the data so if the view is cached as the final product does cake still
try to get the database query. I guess think of a cascade effect if the
action is cached for x amount of time does that override the view and query
cache since that action and the query inside the action would not even be
run since the total "action" and everything inside is cached whatever is
inside the action should be skipped all together no?

$cacheAction as it sounds would cache everything the action does, all its
thinking, data requests and result if your caching the whole action then you
don't need to cache anything else?

Cacheing you query is just the data from the db in a file / memory wherever
you save it

View just the rendered output with the query data in it

$cacheAction = view/123 => 1 month whatever for a rough example


function view ($id) {

//after initial first time viewing of this page everything inside here would
be completely skipped?
If your caching the total actions end result why would you cache the query
data? Would it not be cached inside the action already?

}

I guess with the available options it can be a bit confusing and knowing
when to use with what and when.

Any insight to clear this up would be great.

Thanks all,

K

All that is set up correct. Caching works on other models for me. Just
having issues with this 1 data set. Seems like it just does not want to
delete.

Re: cache action not working

[gremlin]

Do you have debug set to 0? If you are seeing the query log then you
likely don't and with a setting of anything higher than 0 the cache is
cleared on each call to the action.

Re: Cache filenames messed up

[Jeremy Burns | Class Outfit]

This has come up before, but the answer is not obvious. Here's a stolen reply 
from an earlier post:

This is actually caused by a bug in the PCRE library on Centos / Red Hat. See 
this 
http://blog.echothis.com/2011/01/27/fixing-cakephp-1-3s-cache-key-error-on-red-hat-and-centos/

Re: Cache code with APC

[Dr. Loboto]

APC caches code automatically if "opcode cache" is enabled there. It
is by default.
If you want to use APC as data cache with Cake you must setup Cake
cache (example exists in config). It will be "user cache" for APC.

Re: Cache data question / opinion

[Miles J]

Cache anything that shouldn't be dynamic (example pagination is
dynamic, or user data).

I have some cached files that just represent a number, example:
1234345

Instead of querying the database how many users I have, just cache the
number every 24 hours.

Yes, that's exactly it. Check the cache directory to find out how Cake
is naming the cache file in question, then add something along the
lines of:

if ($this->Post->save())
{
clearCache('name_of_cache_file', 'views', '');

Re: Cache does not delete on UPDATE

[Bart]

I see, thanks!

So, the automagically deletion of cache files on UPDATE only works for
View-caching and not for Query-cache/Cache-anything.

I think I mixed those two up.

thanks again!

Re: Cache does not delete on UPDATE

[Ma'moon]

cach engines provided by CakePHP caches the results of a model operation, a
suitable use for this case involves caching the results of a heavy DB query,
"view caching" on the other hand is separated subject, view caching is not
done through the cache engines because the format of the cached data in a
view cannot be "json encoded" as it is in the format of an array or an
object, i hope you can read my point

// are engines unsuitable for storing view files. To clear

This is what I'm referring to:

Re: Cache does not delete on UPDATE

[Bart]

It's not Cache:write() that is not behaving as expected.

It's $this->Post->save() that is not behaving as expected.
I expect it to delete all cache-files that are related to that
particular Post.
But it doesn't.

Re: Cache does not delete on UPDATE

[Ma'moon]

If the cache file does exist && not expired then CakePHP won't overwrite it
until "at least" one of those 2 conditions remains true, otherwise you have
to manually delete the cache file and create it, your save operation is not
changing any of those 2 conditions (removing the original cache file or
changing its expiry) and hence Cache::write won't behave as you expected!
On the other hand, as soon as the target cache file gets expired,
Cache::write() will automatically overwrite the file with the new content!

Re: Cache does not delete on UPDATE

[Bart]

Extra context: writing the cache happens only in the view-action, when
a visitor sees the blog.
I'm not trying to write during the edit-action, I only save/update to
the model. So the Cache::write() and $this->Post->save() happen in 2
separate actions.

I simply expected the cache to be deleted on $this->Post->save();
Has this changed since 1.2?
Because then the cache-file got deleted automatically on $this->Post-
>save();
(AND when it expired, but that's a less relevant here).

thanks for your reaction!
I will try it.

Cache files needs to be explicitly deleted by calling Cache::delete() , make
sure to call it BEFORE calling Cache::write()

Yes, definately. The cache-file is already created (because of
Cache::write() ) and I can see it appear in my filesystem.
The way I write the cache is as follows :

$post = null;
if( ($post = Cache::read('post_'.$id)) === false ){
$post = $this->Post->find('first',
array(  'conditions'=>array('Post.id'=>$id, 'Post.published'=>true),

'contain'=>array(

'ChildPost' => array(

'conditions' => 
array('published'=>true),

'Author','Attachment'

),'Category','Attachment') ) );
Cache::write('post_'.$id, $post);
}
$this->set('post',$post);

The trailing ?> has been omitted from all the all PHP files in Cake

As long as you have var = x in the DB what's the problem? Any requests
for var = $non_existent should give the same result. IOW, you'd only
ever have as many cached views as you have records in the DB. That can
be many but that's the trade-off with caching.

Perhaps you deleted it. In any case, Configure::write('Cache.check',
true) is what you want. That, and Configure::write('Cache.disable',
false)

The stock file does include the closing tag, so, again, perhaps you
(or someone else) deleted it. But its absence is of no consequence. I
generally do not include it because any whitespace after it will often
cause the dreaded "headers already sent" error.

Re: Cache actions vs elements

[Sarpidon]

Thank you for your replies.

I am still somewhat confused. So how do I cache view.ctp ?? it is not
an element, it is displayed through $content_for_layout

I've tried adding  on my elements but it does not seem
to give the result I need.
For example I have this element:

if($this->params['controller'] == 'frontapage'): display image 1 else:
display image 2 endif;


This is not working. When a user requests 'frontpage' the element is
cached with display image 1 and stays like this even if the user
requests another page. If the cache is deleted and the user requests a
page other than the frontpage image 2 is displayed and stays like
this I guess I have to use two different cached elements? Give
them a different key, one for the frontpage and one for the other
pages? But this is not very efficient is it?

Re: Cache actions vs elements

[euromark]

i would include the helper but NOT use the
var $cacheAction = '1 hour'

now set up your elements and cache them as you did before

this way the page itself should not be cached (no cacheAction
declared)
but the elements should!

Re: Cache actions vs elements

[calzone]

I believe cache action is used to cache the entire request.

You would have to use nocache on the sections of your ctp file you
don't want cached
To cache just the elements, you would have to cache the actions
associated with each element.

I meant to cache it on the server. You'd only be serving the entire
day on that user's first request. Any subsequent request for earlier
or later in the schedule for that day would simply slide the table
left or right to the correct position.

Re: Cache

Thanks for the reply.

The number of channels is variable but always more than a 100.

I would prefer not to cache in the client as I would still have to
serve up an entire days worth of the schedule for every user. I
definitely have to cache on the server. I think my best option, if I
cant get Cake to do it, is to use Memcache.

How many channels are you working with? My first thought is to cache
the entire day's schedule and use javascript to display only a certain
portion. Off the top of my head, I'm not quite sure how I'd do that
but I'll bet there's a really elegant way to do that with, say,
jquery. I'm thinking that you'd give the table colgroups [1] IDs based
on the time (note that IDs cannot begin with a digit so prepend some
string to each). Then have your JS parse out the hash portion of the
URL to figure out from where to display from.

So, your JS would, on page load, hide the entire table, then parse the
location.hash value (if not exists, start from the beginning of the
table), and then slide the table colgroups to the left (obviously, use
CSS overflow to hide what is "off" the screen) until the desired time
colgroup is at the left side. Then your paging links would simply call
a JS function to slide the schedule left or right. No reloading the
page.

Does that make sense?

BTW, with Cake, you can create a link with a hash value by using the
'#' option in $html->link().

Re: cache key not working

[Todd McGrath]

More info-

It's 1.3 RC4 I believe.  Not stable congratulations by the way!

Adding to original description, because I'm not sure if it matters,
but the element call is in a for loop:

foreach ($section['AssessmentQuestion'] as $question) {
  echo $this->element('question', array("questionId" =>
$question['id'], "cache" => array('time'=> "+7 days",'key'=>'question'.
$question['id'])));
  // works echo $this->element('question', array("questionId" =>
$question['id']));
}

I said cache is messing up but not 100% sure but it's obvious that
cookie's info is not update unless page is refreshed

How can I get right cookie info without refreshing page after user update
shopping cart or their billing info.

Re: Cache help

[John Andersen]

Ok, based on your code example, the list of offending words are in
your variable $restrictions, which is the same as a list from the
model. So you should be able to use something like:
[code]
if ( in_array($restrictions, 'my bad word') ) {
   // do something with bad word
}
[/code]

This could all be done by a model method, which ensures that the
latest restrictions are read from either the cache or the database,
then checks the word and returns whatever result you want.
Enjoy,
   John

RE: Cache help

[Dave]

Right I know how to read cache if nothing then do the find and cache the
data results. But in this case I want to search the cached data rather than
look for a value in the db directly.

Restrictions is a list of bad words. So I have my full list in the cache
since it rarely changes. So if a user signs up with name "shitface" rather
than search the entire db of words I figured it would be esier to see if its
in the cached data. That’s where im stuck. Instead of find(model) im
searching thru the cached data for name => shitface.

Thanks,

Dave

Re: Cache User queries?

[John Andersen]

Using the Cache (CakePHP book at http://book.cakephp.org/view/764/Cache)
you can cache anything!
When using the Cache::read/write functions, just identify the cached
data as a key together with the users identification. Example:
Cache::write('user_no_'.$this->Auth->user('id').'_favorites',
$favorites, 'daily');

The above will save the favorites in the "user_no_xxx_favorites" cache
file and keep for 24 hours (cache configuration daily).

But read the chapters, understand how it works, and hopefully you will
get the idea.
Enjoy,
   John

Re: Cache MADNESS with Auth

[Chad Smith]

Hello Dario,

If the field is a tinyint (which most likely it is) then in Cake's
mind 1 = true, 0 = false.  You changing it to 2 will confuse Cake and
make it not know what to think.  You will need to change that field to
int and then change the values to 2 if they are confirmed.

When I was developing http://www.countycriminal.com here's what I am
using for the authentication of users:

app/app_controller.php
function beforeRender() {
if(isset($this->params['admin']) && $this->params['admin'] ==
'admin'){

if(!$this->checkUser($this->Session->read('admin_user'))){
$this->redirect('/administrators/login/');
}else{
$this->layout = 'admin';
$this->set('IS_ADMIN',true);
}
}
}

function checkUser($user) {
if((!is_array($user)) || 
(!isset($user['Administrator']['id']))){
return false;
} else {
return true;
}
}

app/controllers/administrators_controller.php
function login() {
$this->layout = "admin";

if(!empty($this->data)) {
$user_login = $this->Administrator->find('first', array
('conditions' => array('username' => $this->data['administrators']
['username'], 'password' => $this->data['administrators']
['password'])));
if(!empty($user_login)){
// Writes the session for the admin
$this->Session->write('admin_user', 
$user_login);
$last = 
$user_login['Administrator']['lastlogin'];
$user_login['Administrator']['lastlogin'] = 
date('Y-m-d H:i:s');
$this->Administrator->save($user_login);
$this->Session->setFlash(__('You have been 
login successfully.
Last Login: '.date('l, F jS Y \a\t g:ia',strtotime($last)), true),
'default', array('class'=>'success'));
$this->redirect('/admin/');
} else {
$this->Session->setFlash(__('The login was 
invalid, please try
again.', true), 'default', array('class'=>'error'));
}
}
}

As you can see the before render will check to see if it's an "admin"
area and if so it checks to make sure the user is logged in.  If they
are not it will send them to the administrators/login page which will
then check their login.  If it's successful it will set the session
and continue on.  If however, it's not successful it will send them
back with a message that it failed to log them in.

Take care hope this points you in the right direction,
Chad

Re: Cache Race conditions, any solution available ?

[Dave J]

I think you pretty much got it right there. The simplest way would be
to set the timeout like you said, in the far future, and then have a
cron job in the background calling the Cake console (or special URL),
which does the real request and sets the cache value.

That would effectively reduce the database requests to only the
necessary ones every N minutes. So you would be in 'control' of
populating the cache, and not the visitors

Funnily enough I was looking at this yesterday. If you implement a
cache wrapper of some kind (e.g. http://bin.cakephp.org/view/129354301
see 
http://code.assembla.com/mi/subversion/nodes/branches/mi_plugin/vendors/mi_cache.php)
Then you could modify your read method to permit restoring and
returning stale data and registering (gearman? afterFilter/destruct
trigger?) a call to regenerate the stale key.

That was the conclusion I reached yesterday, I'd be interested in
other options/opinions.

Re: cache prefix

[Kawina]

It seems that the prefix setting is virtually ignored. I've waded
through the code and found too many instances of "cake_" being hard
coded to want to try to modify it.

I found what seems like a more promising approach that has only worked
partially. My goal is to allow for caches for multiple instances of
the app using the server tmp directory. The approach that partially
worked is changing the path of the cache as follows in cake/config/
paths.php.

Original:
define('CACHE', TMP.'cache'.DS);
Modified:
define('CACHE', TMP.'cache_alt1'.DS);

The problem is that it only works once. Using alt2 in another instance
has no effect and that instance of the application ends up functioning
without a cache. Does anyone have any idea why?

Re: Cache View dose not work

[nurvzy]

APP\views\elements\slide.ctp, line 9

What's on line 9 of slide.ctp?

Follow the backtrace and start commenting out things until you get it
narrowed down what is breaking your cache.

RE: Cache Help

[Dave]

Maybe I should have put in baby steps for you to follow.
1. Click edit
2.Save
3. Save redirects you back to index.
4.Look no new content
5.Click new or edit
6.Save
7.Back to index
8.No new content , add or edit new content and nothing shows up until you
hit refresh...(the index is cached)i know on other sites on the web when you
save or edit your content you don’t have to refresh the page to see your
updatesmaybe the sites I go to are different than the ones you do but im
sure if you thought about it you might see what I mean?
9.Hit refresh
10.WOW LOOK new content

Yes $this->cacheAction = false;

If you don’t have ananswer your can keep your snarky additude response's to
your self "You have to hit refresh to reload a webpage... like everyone
else?" Yes because that exactly what I was asking!

OK, this one confused me. You have to hit refresh to reload a webpage...
like everyone else?

And I've never seen $this->disableCache() before. Since 1.1 I've been using
$this->cacheAction = false;

Re: Cache question

[Dr. Loboto]

Call $this->disableCache(); for sensitive actions. Or call it always
when logged in.

Re: Cache View dose not work

[Miles J]

Try playing the nocache tags in the element itself. You can also pass
an option to the element of cache = false.

element('logininfo', array('cache' => false)); ?>

Re: Cache View dose not work

[Miles J]

Do you get an error when we remove the cache helper?

Also the code should be:


element('logininfo'); ?>

Re: Cache View dose not work

[Miles J]

Can we see some code? Also if its an element, wouldn't it always be
the same? Or are you passing dynamic data.

Re: Cache Problem with safari 4

[Martin Westin]

I am sure Safari does cache the page for you. My feeling is that you
can't fix this with a header. My feeling is that Safari has this
"feature" for some kinds of "back-clicking" no matter what you do.
Possibly it is to aid javascript-heavy sites.

If I click away now, in the middle of typing this post, I can click
back and still have my text in this ajax-loaded field on the page.
Neither the field nor the text were there when the page loaded. That
is not how FF or any other browser works afaik.

I guess the old rule still applies. Back-buttons are for websites...
not applications. :)
(try clicking back in gmail for example)

Did you tried to wrap the clock code in
the view with  tags ?

Re: Cache Problem with safari 4

[p_tucky]

Please test on FF3.5, IE7+ , and Safari4

http://perhabs.com/cake_test

user: test
pass: test

please look at display current time under login button.
After login then click "back button" then see display time Firefox and
IE will show you new time but Safari still display cache time.

That's why I mention Safari still cache.

Thanks

Re: Cache Problem with safari 4

[Martin Westin]

I am not sure that is a cache problem or anything you can fix. Are you
sure

I use Safari 4 all the time and I am under the impression that the
browser sometimes doesn't do any request at all when using the back
button. It simply re-displays what it a few moments ago. I have not
checked if the browser technically does a request or not. It is just a
feeling I get.

Re: Cache not configured properly

[Eric]

Thanks - memcached was not installed correctly.

So it was defaulting back to file caching? I didn't realize you can
cache an individual variable with file caching like that. With no load
on the server, it was just as fast.
