Using Doctrine DBAL, I have some code that inserts a new row into the main database from a form values binded as $telephone_international and $surname.
After that is done, it inserts a new record into a duplicate database. $app['dbs']['backup']
If that's successful, the entry inserted previously the main database gets its copied value updated. The copied column is a timestamp, default value is 0, but the following code should change it to the current time.
$app['dbs']['main']->update('phonebook', array(
'mediated' => 'NOW()'
), array(
'telephone' => $telephone_international,
'surname' => $surname
));
But the value is still 0000-00-00 00:00:00. I wonder if 'NOW()' is being treated as a string.
As i proposed in the comments above, this seems the way to go, as stated here:
http://doctrine-orm.readthedocs.org/en/2.0.x/cookbook/working-with-datetime.html
So try like this:
$app['dbs']['main']->update('phonebook', array(
'mediated' => new \DateTime("now")
), array(
'telephone' => $telephone_international,
'surname' => $surname
));
I stumbled over the same problem. As there's no much and no good documentation for DBAL itself, I'm going to post my solution.
There's a last parameter which specifies the type (in the order of the data and identifcation array merged; as if they were in the same array):
$app['dbs']['main']->update('phonebook', array(
'mediated' => new DateTime()
), array(
'telephone' => $telephone_international,
'surname' => $surname
), array(
'datetime',
PDO::PARAM_STR,
PDO::PARAM_STR
));

I have a simple question regarding Doctrine Modules Object Select.
I have a simple objectSelect form element
$this->add(array(
'name' => 'timezone',
'type' => 'DoctrineModule\Form\Element\ObjectSelect',
'options' => array(
'label' => _('Timezone:'),
'label_attributes' => array('class' => 'required'),
'object_manager' => $this->getEntityManager(),
'target_class' => 'Application\Entity\Timezones',
'property' => 'timezone',
'is_method' => true,
'find_method' => array(
'name' => 'FindAll',
),
),
));
Now I want to select a certain option as default, I have used the setValue method to do this but it is not working.
$this->get('timezone')->setValue(335);
Does anyone know why this is?
Many thanks in advance.
I figured out why it wasn't working.
In my controller I was binding my form to a Doctrine entity which was empty. This was overriding my values I set. I added the values in my controller after the form was bound and this fixed the issue.
$entityManager = $this->getEntityManager();
$site = new Sites($this->getServiceLocator());
$form = new AddSiteForm($this->getServiceLocator());
$form->setHydrator(new DoctrineObject($entityManager));
$form->bind($site);
$form->get('timezone')->setValue(335);
$form->get('currencyCode')->setValue('GBP');
I've got a simple user registration form where a user can choose their own user type. The user type maps to a role. This is part of a zf2 application using the doctrine2 module.
The relevant part of the init() method of my user fieldset looks like this:
public function init()
{
// ... other field definitions ...
$roleRadio = new ObjectRadio('role');
$roleRadio->setLabel('What type of user are you?')
->setOptions(
array(
'object_manager' => $this->objectManager,
'target_class' => 'MyUser\Entity\Role',
'property' => 'roleId',
'is_method' => true,
'find_method' => array(
'name' => 'findBy',
'params' => array(
'criteria' => array('userselectable' => true),
'orderBy' => array('displayorder' => 'ASC'),
),
),
)
);
$this->add($roleRadio);
// ... more stuff ...
}
I'm using Doctrine's ObjectRadio class for this element to automatically populate the value options. Is there any way to set the default selected value?
I know I can just do something like this:
$form->get('user')->get('role')->setValue(3);
But I don't want to hard code this and I also don't want to put that kind of logic in my controller.
Any suggestions?
I don't know what do you mean by "I don't want to hard code this", but you can do it as you said in your controller, or you can do it in the form definition by setting attributes as the following:
$roleRadio->setAttributes(array('value' => 3));
I use doctrine2 with ZF2, some of my libraries work with Zend\Db\Adapter\Adapter, others with doctrine2. Now, they connect to database twice. Is it possible to use one db connection in doctrine and standard ZF2 db adapter?
The DoctrineORM module accepts a PDO resource or a service name where the instance can be located in the service manager instead of the usual connection params.
First step is to create a service factory which retrieves the PDO resource from the Zend\Db\Adapter\Adapter service
<?php
namespace Application\Db\Service;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
use Zend\ServiceManager\Exception\ServiceNotCreatedException;
class PdoResourceFactory implements FactoryInterface
{
/**
* #param ServiceLocatorInterface $serviceLocator
* #return \PDO resource
*/
public function createService(ServiceLocatorInterface $services)
{
$dbAdapter = $services->get('Zend\Db\Adapter\Adapter');
$pdo = $dbAdapter->getDriver()->getConnection()->getResource();
if (!$pdo instanceof \PDO) {
throw new ServiceNotCreatedException('Connection resource must be an instance of PDO');
}
return $pdo;
}
}
Once you have the factory, it's just a case of adding it to the service manager, configuring the db params for Zend\Db\Adapter\Adapter and telling doctrine to use the existing PdoResource from the service manager to connect.
Assuming you did this all in one file, let's say dbconn.local.php...
<?php
return array (
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory',
// include the pdo resource factory
'PdoResource' => 'Application\Db\Service\PdoResourceFactory',
),
),
// db adapter config
'db' => array(
'driver' => 'pdo',
'dsn' => 'mysql:dbname=database;host=127.0.0.1',
'username' => 'username',
'password' => 'password',
),
'doctrine' => array (
'connection' => array (
'orm_default' => array (
'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver',
// use the resource from the zend adapter
'pdo' => 'PdoResource',
),
),
),
);
Sorry for posting this as new answer but I am not able to add a comment to Crisp's answer since my reputation is too low because I only registered to stackoverflow for writing this comment:
In the dbconn.local.php that Crisp posted be sure to set dbname to null like in the following snippet:
Addition to Crisp's answer:
<?php
return array(
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory',
// the lazy way of Crisp's PdoResourceFactory:
'PdoResource' => function (ServiceLocatorInterface $services) {
$dbAdapter = $services->get('Zend\Db\Adapter\Adapter');
$pdo = $dbAdapter->getDriver()->getConnection()->getResource();
if (!$pdo instanceof \PDO) {
throw new ServiceNotCreatedException('Connection resource must be an instance of PDO');
}
return $pdo;
},
),
),
// db adapter config
'db' => array(
'driver' => 'pdo',
'dsn' => 'mysql:dbname=database;host=127.0.0.1',
'username' => 'username',
'password' => 'password',
),
'doctrine' => array (
'connection' => array (
'orm_default' => array (
'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver',
// use the resource from the zend adapter
'pdo' => 'PdoResource',
// important addition to Crisp's answer:
'params' => array(
'dbname' => null,
),
),
),
),
);
And now here is why this is important:
When calling
$em->getConnection()->getDatabase();
on your EntityManager without having set the dbname to null you will get "database" as the name of your database because this is the default value which is set by the module.config.php of the DoctrineORMModule as you can see here. Setting the dbname to null will cause your Doctrine\DBAL\Driver\PDOMySql\Driver which extends Doctrine\DBAL\Driver\AbstractMySQLDriver to load the name of the database via SELECT DATABASE() from the database itself as you can see here.
Also not setting the dbname to null (or to the correct database name) will cause the schemaInSyncWithMetadata() function of the Doctrine\ORM\Tools\SchemaValidator to always return false since it cannot load the current database setup because it uses the Doctrine\ORM\Tools\SchemaTool which uses the EntityManager's Connection which thinks that the database being used is called "database".
So I hope someone can use this information to save some time. I wasted half the day to figure that out.
And many thanks to Crisp again for his answer that saved me a lot of time.
I have a table with a list of person that belong to different categories A and B for example. My problem is that i have a form with DoctrineModule ObjectSelect and i want to show in the ObjectSelect only the name of persons of Category A.
I find this https://github.com/doctrine/DoctrineModule/blob/master/docs/form-element.md#example-3--extended-version but the example is not clear for me and i don't know how to adapt it to my case.
Thank you.
excuse me for my english.
It's actually quite similar to the example you were looking at (I guess that's why there is no example for it), the only difference is that instead of using find/findBy/... you pass your custom repository name as name key, with code similar to this:
$this->add(array(
'name' => 'my-select-object',
'type' => 'DoctrineModule\Form\Element\ObjectSelect',
'attributes' => array(
),
'options' => array(
'label' => 'My Label',
'object_manager' => $entityManager,
'target_class' => 'Application\Entity\MyEntity',
'property' => 'name',
'is_method' => true,
'find_method' => array(
'name' => 'myCustomRepositoryMethod',
'params' => array(
),
),
),
));
Also notice that your entity needs to know about repository existence, so make sure it uses this line:
#ORM\Entity(repositoryClass="Application\Entity\Repository\MyCustomRepository")
So when you open the form with this ObjectSelect it will call you repository method instead of loading the dropdown directly. That method should just return an array of entity objects which are then used by ObjectSelect to generate select element's options.
I can't help myself and it's currently annoying, and yes, I used google a lot.
What I need:
A twitterlike follow button with the action to follow user.
What I already did:
Database
users table: id, username, password, ...
users_users table: id, user_id, follower_id
Code
In model User.php
public $hasAndBelongsToMany = array(
'Follower' => array(
'className' => 'User',
'joinTable' => 'users_users',
'foreignKey' => 'user_id',
'associationForeignKey' => 'follower_id',
'unique' => 'keepExisting',
)
);
In UsersController.php
public function follow() {
/*need help here*/
}
In Users\index.ctp
<?php if ($current_user['id'] != $user['User']['id']) echo $this->Html->link('Follow', array('action' => 'follow', $user['User']['id'])); ?>
Personally, I don't find hasAndBelongsToMany to be a good fit for situations like this. It's a good fit for when you want to display a list of checkboxes, or a select list, and allow the user to select/manage all their followings (or whatever the relationships might be) in one form.
It might just be my personal preference, but in situations like yours, where you're adding/deleting single links without worrying about any of the other links related to that user, I prefer to just create a separate 'Relationships' (or similarly named) Model / Controller, and consider the records as things in their own right, as opposed to just hasAndBelongsToMany links that are all sort of 'automagically' managed.
Here's how I'd do it:
Name your users_users table 'relationships'. And name the columns 'followed_by_id' and 'following_id' (or similar) to avoid any ambiguity as to which user is the follower / followee (if that was a word!).
In your users Model, you'd have these relationships:
var $hasMany = array(
'Followers' => array(
'className' => 'Relationship',
'foreignKey' => 'following_id',
'dependent'=> true
),
'FollowingUsers' => array(
'className' => 'Relationship',
'foreignKey' => 'followed_by_id',
'dependent'=> true
),
);
Then you'd have a Relationships model that looks something like this (the $belongsTo relationships are the important part):
<?php
class Relationship extends AppModel {
var $name = 'Relationship';
var $validate = array(
'followed_by_id' => array(
'numeric' => array(
'rule' => array('numeric'),
),
),
'following_id' => array(
'numeric' => array(
'rule' => array('numeric'),
),
),
);
var $belongsTo = array(
'FollowedBy' => array(
'className' => 'User',
'foreignKey' => 'followed_by_id'
),
'Following' => array(
'className' => 'User',
'foreignKey' => 'following_id'
)
);
}
?>
And then in your Relationships controller, you'd have something like this:
function add($following_id = null) {
$this->Relationship->create();
$this->Relationship->set('followed_by_id',$this->Auth->User('id'));
$this->Relationship->set('following_id',$following_id);
if ($this->Relationship->save($this->data)) {
// all good
} else {
// You could throw an error here if you want
$this->Session->setFlash(__('Error. Please, try again.', true));
}
$this->redirect($this->referer());
}
Then to add relationships, you obviously just call the add method of your relationships controller.
NOTE: Ideally, since adding a relationship is changing the database, it ideally shouldn't be done with a GET request accessed by a regular URL. It should be done via submitting a form via POST. I know that seems overkill when it's so easy to just do it via a regular link with GET. I haven't bothered to use forms/POST in this example - but if you want to stick to best practices, that's what you should do.
