model->delete error
Hi,
I have v1.3.2 running on a production site that has in a controller:
(effectively, some non-related code removed)
$results = $this->Pipe->find('all', array('conditions'=>$conditions));
if(sizeof($results) > 1) {
$pipes = sizeof($results);
for($i = 0; $i < $pipes - 1; $i++) {
$this->Pipe->id = $results[$i]['Pipe']['p_id'];
$this->Pipe->delete();
unset($results[$i]);
}
}
so that all but one matching record remains.
Typically, for months now and even within seconds of the error, the
SQL generated by this code was:
DELETE FROM `pipe` WHERE `pipe`.`p_id` = 12345;
until the one time on yesterday it issued:
DELETE FROM `pipe` WHERE 1 = 1;
(There went 36+ records) I see this in the MySQL binlog but cannot
tell what value for id was set. It is my understanding that in no
reasonable case should this cause this SQL to be generated.
Does anyone have an alternate understanding or insight into what went
wrong?

Re: Model->find with large datasets
You will still want to page through the results so that there is not a
huge resultset in memory at once.
$limit = 1000; // some optimal amount of records
$page = 1;
$results = null;
do {
$results = $his->MyModel->findAll($conditions, null, null, $limit,
$page++);
foreach ($results as $row) {
// processing
}
} while (!empty($results);
Something like the above to get pages of results.
HTH,
David Lloyd

Re: View Caching of Home Page
The problem is that the file is created by the value of $this->here
and if that is the same as cacheAction or in the array of
cacheAction. Then when hitting the site the same url has to be used.
The easiest solution off the top of my head is to use mod_rewrite to
force ^$ and ^/$ to go to your custom controller/action
RewriteRule ^$ index.php?url=/mycontroller/myaction [QSA,L]
RewriteRule ^/$ index.php?url=/mycontroller/myaction [QSA,L]
# everything else below
I have not tried it but hope it helps,

Re: md5_file
hashes are just a number so a collision is certain with a large enough dataset. CRC is usually 32 - 64 bits and MD5 is 128 bit. They are pretty good at making sure you have the file you knew you wanted - i.e. checking for transmission errors. To check against a duplicate file I would want something better. At least the MD5 , filelength , and first n bytes of the file (32+?). If all three were the same it would be a real good check but not definitive. The more you can check against the better until you actually compare byte-to-byte the two files.

Recursive Association joins with conditions 3+ deep
I posted some questions on the group and on the IRC in late October and early November. http://groups.google.com/group/cake-php/browse_thread/thread/7ac86a4ad74198b4/8f2cbc16312a05e4?lnk=gst&q=recursive+query&rnum=1#8f2cbc16312a05e4 I'd post IRC archive links but I can't seem to connect to irc.cakephp.org Three and a half months later I have been refining this code from time to time while using it on two of my web sites. One of them is quite large and was the original need. The first of the patches was in 1.1.9 and then 1.1.10, 1.1.12, 1.2alpha. I may do a patch for 1.1.13 but have been focusing efforts on 1.2. Most of this code was complete about 11/14 after speaking with nate and phpnut on irc. The intense work load and holiday season keft me from writing it up. I have synopsis and the patched code at http://lloydhome.com/blog/archives/2007/02/Recursive-Association-Support-in-CakePHP.html. Please test this yourself and leave comments. I hope to write some unit tests that are generic as what I have is specific to my website and use. Then this will be ready to submit as a fix to Trac issue #633 (https://trac.cakephp.org/ticket/633).

Re: Navigation Component / Helper
Your example is good but you need to set the return attribute.
$this->set($menu, $this->Categories->requestAction('/categories/
getCategoryList', array('return'=>1)));
This is the type of thing that could use a cache as I descibed
http://lloydhome.com/blog/archives/2007/02/More-Caching-in-CakePHP.html
and
http://groups.google.com/group/cake-php/browse_thread/thread/5e0034e1ce6c4798/#
If you follow the caching I posted then also add the cache parameter.
$this->set($menu, $this->Categories->requestAction('/categories/
getCategoryList', array('return'=>1, 'cache'=>1)));

requestAction view caching and user authentication of cached views
I have a user portal that gathers information from multiple
controllers. The logic belongs in those controllers. The portal
obtains these viewlets via requestAction() calls. RequestAction is
notoriously slow and had no chance of using the view cache. This has
really sped up my requestAction calls that are database and logic
heavy.
I modified my dispatcher.php dispatch method to first look for a cache
if its an internal call...
if (!empty($additionalParams) && !empty($additionalParams['cache']))
{
// requestAction had no prior chance to get cached
version so check
here
if (defined('CACHE_CHECK') && CACHE_CHECK === true) {
$uri = Router::url($url);
if (empty($uri)) {
$uri = setUri();
}
if (!isset($TIME_START)) {
$TIME_START = getMicrotime();
}
if (strpos($uri,'/bare/')===false) { // we want
to force a bare
cache
$filename = CACHE . 'views' . DS .
'bare_' . convertSlash($uri) .
'.php';
} ele {
$filename = CACHE . 'views' . DS .
convertSlash($uri) . '.php';
}
if (file_exists($filename)) {
uses('controller' . DS . 'component',
DS . 'view' . DS . 'view');
$v = null;
$view = new View($v);
if ($view->renderCache($filename,
$TIME_START, false)) {
return;
}
} elseif(file_exists(CACHE . 'views' . DS .
'bare__' .
convertSlash($uri) . '_index.php')) {
uses('controller' . DS . 'component',
DS . 'view' . DS . 'view');
$v = null;
$view = new View($v);
if ($view->renderCache(CACHE . 'views'
. DS .
convertSlash($uri) . '_index.php', $TIME_START)) {
return;
}
}
}
}
and modified my View::renderCache to accept a third parameter
function renderCache($filename, $timeStart, $dieOnSuccess = true) {
and not die(); in there if it is false.
If this is not formatted in your email, see http://lloydhome.com/news/
view/6.
Also, I have posted an article on user authentication within cached
pages at http://lloydhome.com/news/view/5. It is a Smarty article but
it is usable for ctp and thtml files that are cached and need a
controller's beforeFilter() run to allow user authentication.

Re: How to use smarty cache in cakephp?
I only have one page that is cached and has dynamic data on it. It
was really messy with Smarty and there are some other features I
wanted so I have decided to clean it all up. See
http://www.lloydhome.com/news/view/5
for a full explaination. AS A BONUS, you get the controller's
beforeFilter() to run before showing cached content - just be careful
with what you do. It should be used to authenticate that the cache is
available to the user.
The short answer for those searching in the future: You have to set
the $this->_tpl_vars array to the variables you want accessed. This
can only be set if it is empty (cached case). This is a hoop to go
through but the alternative is usually a worse set of {php} global
$foo; {/php} .
HTH,
David Lloyd

Re: How to use smarty cache in cakephp?
As this is using Cake's cache the SAME limitations are applied.
How is it that 'time' will be set in the view if the controllers are
not run? When it is cached NO CONTROLLERS are run. NO SMARTY is
run. Only the session variables are available.
I see in my template it is difficult to get a clean code except in my
situation so I will change the SmartyView to have easier caching. But
you still will have to rethink how your variables are accessed.
I'll reply back soon,
David Lloyd

Re: How do I stop the return of unwanted associated data?
See http://manual.cakephp.org/chapter/models and then look at Section 2 "findAll" takes recursive that limits the depth or look at Section 3 where model has "var $recursive" that limits it as the default (overridden by calls like findAll, find, etc.).

Re: Associations help - overriding primary key?
I have not tried doing this before but if I were to try I would first
create duplicate model classes for the models needing a different
primary key defined. There should be no reason why two model classes
point to the same db table except that it seems weird.
class ContactEmail extends AppModel {
var $tableName = 'contacts';
var $primaryKey = 'emailAddress';
var $belongTo = ...
}
And override the various fields as needed and ditto for the
MailMessage if needed.
YMMV ....

Re: How to use smarty cache in cakephp?
Quote from previous:
If you use it should work as long as the tag is in
the layout file.
That means it is not working in the included views - like yours. It
would not work anyway with your case as no controller would run to set
$time. The dynamic part must come from session or other outside
means.

Re: Component can't create a model
Assuming you are running on v1.2, you now have to specify
loadModel('Session');
before allocating a model not specified in the uses array. Models are
no longer automatically loaded but are loaded only as needed to
improve performance.

Re: How to use smarty cache in cakephp?
I have a SmartyView that handles caching by utilizing cake's page
caching. It handles full-page caching great. If you use
it should work as long as the tag is in the layout
file. I have need for a cachable, non-static ajax call with no layout
and this solution nor cake's default works for me. So I have an idea
for that too but you'll need to be patient.
The file is at http://www.lloydhome.com/files/smarty.ph_.txt and needs
to be renamed and placed in your /app/views directory.
To use in your controller:
var $view = 'Smarty';
var $cacheAction = 300; // 5 minutes
var $helpers = array('Cache');

Re: Change content on frontpage ?
Putting code in app/pages/... is not going to get you your notes as the NotesController (or some other controller you write) will need to be called. As is, the PagesController is being called and it does not get your notes. Following the tutorial you mentioned, you would want a page in /app/ views/notes/default.thtml and a method in NotesController called default() to get the notes. Or if you want to use the scaffold generated index, change your application app/config/routes.php to point "/" to "/notes/index". All of this is explained in the manual http://manual.cakephp.org - you really need to read it through several times to catch everything.

Re: Passing back a dynamically generated image
I do it quite often. I have sites that generate images from gd and
sites that use ChartDirector. In the controller turn off the
rendering engine
$this->autoRender = false;
or

You might have to set the MIME type if JPGraph doesn't
header("Content-type: image/png"); // or jpeg or gif, etc.
then output it
print($c->makeChart2(PNG));

Re: legacy data
I think all you will need is to first verify that your User model can
access users and your Product model can access products from their
respective databases. Then create your association between the two as
normal. The difference is that you should set the 'external'
attribute to true in the association.
i.e.:
var $hasMany =
array('Product'=>array('className'=>'Product','external'=>true,'foreign_key'=>'user_id');

Re: A Super Release
With the holidays over we have been getting ready to upgrade our
production systems to 1.1.12. Now with '13 out the pressure is on.
>From reading this list there are still many on 1.1.10 or even
earlier. Here is one way we have reduced our workload and code
complexity. I do not like littering the 'uses' array with unnecessary
models and it defeats the lazy loading if you only need a model in
some circumstance.
In AppController:
function & constructModel($modelname) {
if (!class_exists($modelname)) {
loadModel($modelname);
}
$m = new $modelname();
return $m;
}
function usesModel($modelname) {
if ( !isset($this->{$modelname})) {
if (!class_exists($modelname)) {
loadModel($modelname);
}
$this->{$modelname} = new $modelname();
}
}
Then in the code I use constructModel like
$auser = $this->contructModel('User'); // instead of $auser = new
User();
or
$this->usesModel('User'); // instead of $this->User = new User();

Re: Existing Projects
It certainly works! One of my client's database was built before I took over. It used to be spaghetti-code PHP that I have (mostly) converted to CakePHP. This database has as primary keys user_id, j_id, prodid, etc. A foreign key to user_id may be j_owner and to prodid is rfc_prodid. You have to specify the primary key's name and in the associations specify foreign key's name. It is more work but does work nicely. One caveat is how the magic functions work. Just remember how the conventions work and you'll do okay. To find the user_id use $this- >User->findByUserId(1) because the capital I means there is a _. To find by prodid use $this->Product->findByProdid(1). Notice no capital I prodid as there is no _.

Re: This->query output
Phil,
For most things it is better to have the data the way it is returned.
I would encourage you to work within the framework and not against it.
That said, maybe you have some logic that is legacy like I do. I am
porting a clumsy mess of code into Cake but it cannot be done all at
once. I have old methods that want the data in a flat associative
array as you describe. In my AppModel class I put:
/**
* Totally flatten an array.
*/
function & array_flatten(&$array) {
if (is_array($array)) {
$newarray = array();
foreach ($array as $k=>$v) {
if (is_array($v)) {
$newarray += $this->array_flatten($v);
} else
$newarray[$k] = $v;
}
return $newarray;
}
return $array;
}
Then to use:
$newarray = array();
foreach ($results as $v) {
$newarray[] = $this->User->array_flatten($v);
}

Re: Fetching data with join over 3 tables with recursive association query
Well, it seems I have found the previously reported Trac #633. The
partial workaround mentioned by elsigh is clumsy, messy, and may not
work for some implementations but has the advantage of actually working
without changing core code.
My implementation requires a proper recursion depth to be specified but
it automagically gets the query right. The implementation proposed in
#633 may not require a recursion to be set but requires the path. I
think the both have merit. So the difference in my case is between
$this->User->findAll(array('Region.region_name','Canada'),null,null,null,1,3);
and
$this->User->findAll(array('Subarea.Area.Region.region_name','Canada'))
Can I get comments from 'those in the know' on which way this should be
implemented? Is there work occurring on #633? If so, I would like to
know the strategy so my code won't break. If not, I can clean up my
implementation to work the way it should and submit it.
Thanks,
David

Re: Fetching data with join over 3 tables
I have used CakePHP for several months and answered a few posts without
needing to post and I probably don't need to now but I cannot find the
answer.
I have tried setting the recursive var to 2, 3, 4, 5 and no help to my
problem. I have a User model that has a belongsTo a Subarea that
belongsTo an Area that belongsTo a Region. The associations are corret
(I think) because the recursion works in the case described above. My
problem is when a field is in a condition that is not 'close' to the
first model.
regions
--
region_id int primary key,
region_name varchar(50) not null unique key
...snip...
areas
--
area_id int primary key,
area_regionid int references regions(region_id),
area_name varchar ...
...snip...
subareas
--
subarea_id int primary key,
subarea_areaid int references areas(area_id),
subarea_name varchar ...
...snip...
users
--
u_id int primary key,
u_subareaid int references subareas(subarea_id),
login_name varchar(50) not null unique key,
...snip...
class Region extends AppModel {
var $name = 'Region';
var $primaryKey = 'region_id';
var $hasMany = array(
'Area'=>array('className'=>'Area','association'=>'Area','foreignKey'=>'area_regionid')
);
}
class Area extends AppModel {
var $name = 'Area';
var $primaryKey = 'area_id';
var $belongsTo = array('Region'=>
array('className'=>'Region','association'=>'Region',
'foreignKey'=>'area_regionid') );
var $hasMany = array(
'Subarea'=>array('className'=>'Subarea','association'=>'Subarea','foreignKey'=>'subarea_areaid')
);
}
class Subarea extends AppModel {
var $name = 'Subarea';
var $primaryKey = 'subarea_id';
var $recursive = 2;
var $belongsTo = array('Area'=>
array('className'=>'Area','association'=>'Area',
'foreignKey'=>'subarea_areaid') );
// ...snip business logic...
}
class User extends AppModel {
var $name = 'User';
var $belongsTo = array('Subarea'=>
array('className'=>'Subarea','association'=>'Subarea',
'foreignKey'=>'u_subareaid') );
var $primaryKey = 'u_id';
// ...snip business logic...
}
if I query from my controller ...
$result_count =
$this->User->findCount(array('Region.region_name'=>'Canada'), 4);
I get an error in this generated query:
SELECT COUNT(*) AS count FROM `users` AS `User` LEFT JOIN `subareas` AS
`Subarea` ON `User`.`u_subareaid` = `Subarea`.`subarea_id` WHERE
(`Region`.`region_name` = 'Canada')
1109: Unknown table 'Region' in where clause
If I commit a cardinal sin and modify dbo_source.php and insert the
following 10 lines into the read method before the comment here:
//DAL: HACK in recursive query joins!
if ($model->recursive > 1) {
foreach($model->__associations as $type) {
foreach($model->{$type} as $assoc =>
$assocData) {
$linkModel =&
$model->{$assocData['className']};
$this->__dal__generateRecursiveQuery($model, $linkModel,
$queryData, $model->recursive);
}
}
}
---> before
// Build final query SQL
and add the methed mentioned:
function __dal__generateRecursiveQuery(&$model, &$linkModel,
&$queryData, $recursive) {
if ($recursive>0) {
foreach($linkModel->__associations as $type) {
foreach($linkModel->{$type} as $assoc => $assocData) {
$newLinkModel =&
$linkModel->{$assocData['className']};
$external = isset($assocData['external']);
$null=null;
if ($newLinkModel && $model->useDbConfig ==
$newLinkModel->useDbConfig) {
$this->generateAssociationQuery($linkModel, $newLinkModel, $type,
$assoc, $assocData, $queryData, $external, $null);
$this->__dal__generateRecursiveQuery($model,$newLinkModel,$queryData,$recursive-1);
}
}
}
}
}
It gets better. Now modify the REALLY weird code in the
__filterResults method
if (isset($model->{$className})
&&
is_object($model->{$className})) {
$data =
$model->{$className}->afterFind(array(array($key =>
$results[$i][$key])));
} else {
//DAL: this
makes no sense. The 'if' above proves it is not an object to call ...
//DAL:
$data = $model->{$className}->afterFind(array(array($key =>
$results[$i][$key])));
$data[0][$key]=& $results[$i][$key];
}
AND IT WORKS! But I get suspicious when I go modifying the core

Re: View caching
I appreciate your pointing this out to me. Especially since I have read everything I can find about CakePHP but I have never seen any documentation for this. PEAR::Cache_Lite has a 4 year history of improvement, stability, and speed. Other than the complete obscurity of Cake's cache (which now I know its name a simple search reveals it is in basics.php) are there any benefits besides being able to use in an environment where PEAR is not allowed? Sorry for the flame bait. I think the simplest workable solution is best. So when I wanted a local cache I loked at Cake first. Seeing the docs for Cache model and no reference of any other, I thought that was it. If I had seen docs I would have used it. If I found NO docs on caching I would have asked. Lorenzo: I avoided the Cache Model class because of the DB calls. There is nothing intrinsically wrong with it. In some situations you may atually want that. I just wanted a local cache that need not hit the network or database. Thanks, David --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Cake PHP" group.

Re: View caching
For lengthy operations I create a method in the model and cache the
results. Say I have sale people whose main portal page contains action
items, deals about to close, closed deals, and current prospect status.
This data is referenced slightly different ways in various parts of
the app. Also, this main page is shown repeatedly through the session
when the user is navigating. Parts of the data can update alot, others
rarely.
so closed deals changes rarely (less than once a day) but the query is
real harsh:
class Revenue extends AppModel {
function getRevenue( $country, $region, $year ) {
$cache =& $this->getCache(); // constructs Cache_Lite object
$cachedata = $cache->get("$country-$region-$year",'revenue');
if ($cachedata === false) {
$revenue = array();
// do big query here
// populate $revenue with results optimized for reuse
$cache->save( serialize($revenue) );
} else {
$revenue = unserialize($cachedata);
}
// allow getCache to not reconstruct
// if needed again soon
$this->releaseCache($cache);
return $revenue;
}
}
Part of my AppModel:
define('_APPMODEL_CACHE_DEFAULT_TIME_', HOUR * 15);
class AppModel extends Model{
var $_cache = null;
const CACHE_DEFAULT_TIME = _APPMODEL_CACHE_DEFAULT_TIME_;
function & getCache() {
if (!$this->_cache) {
$cache = $this->createCache();
} else {
$cache = $this->_cache;
}
$this->_cache = null;
return $cache;
}
function & createCache($lifetime=AppModel::CACHE_DEFAULT_TIME) {
$options = array(
'cacheDir' => APP.'tmp/cache/persistent/',
'lifeTime' => $lifetime,
'pearErrorMode' => CACHE_LITE_ERROR_DIE,
'fileNameProtection' => false
);
$cache = new Cache_Lite($options);
return $cache;
}
function releaseCache(&$cache) {
$this->_cache = & $cache;
}
}
and you can do the same with other data on the page. ALL of my simple
lookups that are database tables that change rarely are cached and
retrieved this way so no form has to do constant DB lookups just to get
a list of product codes, countries, whatever. Stay off of your
database as much as possible and yor scalability soars.

David

Re: View caching
I agree that smarty is a great drop in view replacement for cake and it is what I use. However, for user specific differences, my best bang for the buck has been long term model caching. I use Pear's Cache_Lite in my model classes where I know a lengthy operation can be cached. I create accessor method in the model which performs the query(ies) and caches the results for several hours. If you categorize your caches correctly, then you can invalidate only the ones affected by a data change. The advantages I get are some caches are 5 minutes, some are 15 hours - I decide how long based on the data stored. Many times what I store is not table data but end result of large calculations specific to my needs. Pages that would take 5+ seconds to load everytime now take 3 seconds on the first hit and <1 for subsequent hits by the same user (Iknow it doesn't add up, it reuses other caches). Also the advantage is storing the caches on the local file system. That way multiple webservers have local caches and do not hit the network or database to get a result - except when the cache is stale.

Re: formatting model values
I think it is a matter of taste and how you want to use it. The simple solutions are if it is view-centric then a simple helper might do the trick. The other is to create a lookup table in the database, a model, and hookup the associations.

Re: pretty code.
You can achieve what you want if you use Smarty as the template engine.
I currently do
{if_user_allowed access=some/protected/resource}
{$html->link('New Case','/ccases/add')}
{/if_user_allowed}
I had to write the if_user_allowed plugin but they are extremely easy
in 20-30 lines.

Re: Pulling data to the home page
I think AD7six was referring to your comment of wanting to use getUserList as an AJAX call. With AJAX, you would want to set your layout to something bare so you do not get the full page layout. RequestHandler would take care of some of this but not for this case AFAICT. In getUserList() call $this->layout = ''; or set it to 'ajax' or other bare layout. This way it works for ajax and for when you call it via requestAction. HTH, David --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Cake PHP" group.

Re: Map non-cake PHP files to a default controller like PagesController
There is no old() method. See the pages controller to see how the
display() method gets called for everything and parses the path info
itself.
As far as placing it in the webroot/content: you might get that to work
... dunno and don't really wanna try ... maybe by playing with
$viewPath or filename. Might be easy enough to create a
views/spages/default.thtml that has
include "/path/to/webroot/content/$myfilename"
and have the controller
$this->set('myfilename', )
But your milage may vary :/

Re: Map non-cake PHP files to a default controller like PagesController
I moved all of my legacy files to the view directory of my controller.
I then added this to the top of my .htaccess
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} ^(.*)php$
RewriteRule ^(.*)\.php$ index.php?url=/spages/old/$1 [QSA,L]
where Spages is my controller and my legacy files are in
views/spages/old/
Esentially, Spages is a secure Pages controller with extra logic. I
copied what I needed from pages_controller (most of it) and added my
extra logic, beforeFilter, etc. The code from pages controller takes
care of the old files and your extra logic for session authentication
and such is the extra logic. I have some files that render Excel or
PNG and don't want the layout around it. So in the controllers
display() method set $this->layout='' for those files. This is a
pretty quick and dirty way to do it without fighting the framework.
