How do I remove the foreign key constraint?

Filename: plugins/doctrine_pi.php
Line Number: 5″

So in the file doctrine_pi.php I changed the paths that use APPPATH to:
(line 5) require_once APPPATH.’../plugins/doctrine/lib/Doctrine.php’;
(line require_once APPPATH.’config/database.php’;
(line 31) Doctrine::loadModels(APPPATH.’models’);

Now when I call example.com/ci/index.php/hello/world it gives me no error message, only the expected “Hello CodeIgniter!”.
Then when I call example.com/ci/index.php/hello/user_test I get:

“A PHP Error was encountered
Severity: Warning
Message: PDO::__construct() [pdo.--construct]: [2002] Invalid argument (trying to connect via unix://)
Filename: Doctrine/Connection.php
Line Number: 470″

I checked and it seems it has something to do with the $dsn array in doctrine_pi.php.
So I went and gave it the MySQL info that I use for my CI project:
$dsn = $db[$connection_name]['dbdriver'] .
‘://’ . $db[$connection_name]['root'] .
‘:’ . $db[$connection_name][''].
‘@’ . $db[$connection_name]['localhost'] .
‘/’ . $db[$connection_name]['ci_linksdir'];

But then I get these errors:
“A PHP Error was encountered
Severity: Notice
Message: Undefined index: root
Filename: plugins/doctrine_pi.php
Line Number: 19

A PHP Error was encountered
Severity: Notice
Message: Undefined index:

Line Number: 20

Filename: plugins/doctrine_pi.php
Line Number: 21

A PHP Error was encountered
Severity: Notice

Line Number: 22″

I am at my wits end lol.

Thanks for great tut.

But unfortunately I have a problem with my relations. I can’t figure what the problem is, and its most likely something stupid that I did. Any help will be great.

Fatal error: Uncaught exception ‘Doctrine_Connection_Mysql_Exception’ with message ‘SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`ci_doctrine`.`post`, CONSTRAINT `post_companys_id_companys_id` FOREIGN KEY (`companys_id`) REFERENCES `companys` (`id`))’ in C:\wamp\www\ci_doctrine\system\application\plugins\doctrine\lib\Doctrine\Connection.php:1082 Stack trace: #0 C:\wamp\www\ci_doctrine\system\application\plugins\doctrine\lib\Doctrine\Connection\Statement.php(269): Doctrine_Connection->rethrowException(Object(PDOException), Object(Doctrine_Connection_Statement)) #1 C:\wamp\www\ci_doctrine\system\application\plugins\doctrine\lib\Doctrine\Connection.php(1042): Doctrine_Connection_Statement->execute(Array) #2 C:\wamp\www\ci_doctrine\system\application\plugins\doctrine\lib\Doctrine\Connection.php(687): Doctrine_Connection->exec(’INSERT INTO pos…’, Array) #3 C:\wamp\www\ci_doctrine\system\application\plugins\doctrine\lib\Doctrine\Connection\UnitOfWork.p in C:\wamp\www\ci_doctrine\system\application\plugins\doctrine\lib\Doctrine\Connection.php on line 1082

The code:
class Post extends Doctrine_Record {

public function setTableDefinition() {
$this->hasColumn(’content’, ’string’, 65535);
$this->hasColumn(’category_id’, ‘integer’, 4);
$this->hasColumn(’companys_id’, ‘integer’, 4);
}

public function setUp() {
$this->actAs(’Timestampable’);
$this->hasOne(’Category’, array(
‘local’ => ‘category_id’,
‘foreign’ => ‘id’
));
$this->hasOne(’Companys’, array(
‘local’ => ‘companys_id’,
‘foreign’ => ‘id’
));
}

}

class Category extends Doctrine_Record {

public function setTableDefinition() {
$this->hasColumn(’title’, ’string’, 255);
}

public function setUp() {
$this->hasMany(’Post as Posts’, array(
‘local’ => ‘id’,
‘foreign’ => ‘category_id’
));
}
}

class Companys extends Doctrine_Record{
public function setTableDefinition() {
$this->hasColumn(’companyName’, ’string’, 255, array(’unique’ => ‘true’));
$this->hasColumn(’contactPerson’, ’string’, 255);
$this->hasColumn(’contactNumber’, ’string’, 255);
$this->hasColumn(’mobileNumber’, ’string’, 255);
$this->hasColumn(’email’, ’string’, 255, array(’unique’ => ‘true’));
$this->hasColumn(’password’, ’string’, 255);
$this->hasColumn(’category_of’, ’string’, 255);
}

public function setUp() {
$this->setTableName(’companys’);
$this->actAs(’Timestampable’);
$this->hasMutator(’password’, ‘_encrypt_password’);
$this->hasMany(’Post as Posts’, array(
‘local’ => ‘id’,
‘foreign’ => ‘companys_id’
));
}

protected function _encrypt_password($value)
{
$salt = ‘#*seCret!@-*%’;
$this->_set(’password’, md5($salt . $value));
}
}

In my case it got fixed by adding following lines in doctrine_pi.php – before Doctrine::loadModels –

$manager = Doctrine_Manager::getInstance();
$manager->setAttribute(Doctrine_Core::ATTR_MODEL_LOADING, Doctrine_Core::MODEL_LOADING_CONSERVATIVE);

I have a problem with cart library. The problem is that i can have only 4 items in it.. when i add 5 items they appear in cart->contents() but after reload it’s got cut and theres only 4 of them…

Can you help me?

Can I force this somehow in Linux?

When I transferred my project (setup as is on WAMP) to LAMP my site does not display at all. I just get a blank page

no errors showing even if I try going to different url paths, removed htaccess to elimate that as a problem still nothing displays, I get the feeling my models are not being loaded or there is no database connection being made at all?

Is there something I need to set up differently for doctrine/ci to work on linux? Also my hosting server only has PHP 5.2.13 not 5.2.3 as stated on doctrine but this doesnt seem to matter on my local machine which is using 5.2.11?

Any help/suggestions would be greately appreciated
Thanks
