I need little help to call method from entity.
Here is the code I had try to execute.
$datat = $this->getDoctrine()
->getRepository('AppBundle:users')
->findBy(array('userId' => $userId));
after this, when I call
$data->getUser();
I get message about exeption "Error: Call to a member function getUser() on a non-object"
When I dump $data I got data from table or if I execute
->find() with ID value.
findBy returns generally an ArrayCollection.
You should use findOneBy instead in order to target only one entity...
So :
$datat = $this->getDoctrine()
->getRepository('AppBundle:users')
->findOneBy(array('userId' => $userId));
Your method getUser() doesn't exist in users entity.
Just iterate over your $datat and called method from user object like that
foreach ($users as $user) {
// $user is an instance of users
echo $user->getName(); //if this method exist in your entity model
}

I'm trying to find a user form a database with 'email' = $email and send them an email. When I try to echo the $user, I receive an error that it's not a string.
public function sendEmail($user)
{
Mail::to($user['email'])->Send(new VerifyEmail($user));
}
public function verifyEmail($email)
{
$user = User::where('email',$email);
$this->sendEmail($user ); //mail won't send
return view('auth.email.verifyemail')->with('email', $email);
}
Please help, thank you!
Your code has a few more issues than not being able to find the user, but let's address this first.
Explanation
Calling the where() method on the User::class is returning an instance of Illuminate\Database\Query\Builder and not the record that you are looking for.
To get a collection of records you can call fluently the get() method or in your case you can just get the first result by calling first().
More on the topic: Retrieving Single Models / Aggregates
Solution
$user = User::where('email', '=', $email)->first();
if(!$user) {
// handle the case if no user is found
}
echo $user->email // access the user's email address
Then you can call your sendmail method or whatever you need and pass the $user instance like this $this->sendmail($user)
$thisUser has only a query. You need to execute it to get the user. Try to get the first record:
$thisUser = User::where('email',$email)->first();
I am writing a Symfony3 appusing Doctrine ORM.
SO what i am trying to do is to find if a given email address exists in a table (every email is unique). so i have a user repository with some attributes I can easily persist data to the db but failing to retrive data.
/**
* #param $email
*/
public function findUserByEmail($email)
{
$user = $this->getDoctrine()
->getRepository('TestBundle:TestUser')
->find($email);
if (!$user) {
echo 'Error';die();
}
}
I know the var passed to the function contains a email string, but what i get in return is error and when i var_dump $user before the if statment i get null.
I followed the Symfony docs
Your User probably has a separate primary key field. the find() method on a repo only retrieves by primary key.
Repositories use __call to dynamically process findBy* and findOneBy* methods, so you could call it like this:
$repo = $this->getDoctrine()->getRepository('TestBundle:TestUser');
// magic find method
$user = $repo->findOneByEmail($email);
// explicit find method
$user = $repo->findOneBy(['email' => $email]);
// custom QueryBuilder
$user = $repo->createQueryBuilder('user')
->where('user.email = :email')
->setParameter('email', $email)
->getQuery()
->getSingleResult();
BTW: If you are validating this for a submitted form, there is a contraint that does this check for you: UniqueEntity
I think the problem is because you forgot to call getManager().
So the code would be:
$em = $this->getDoctrine()->getManager();
$user = $em->getRepository('TestBundle:TestUser')->findOneBy(['email' => $email]);
Hope it would help you!
I have a collection and I am calling first() method on it with a closure expecting a parameter say $model.
Upon execution, if I try to access a property of $model; it says:
Accessing property of non-object
I tried dumping $model and found that it has a integer 1 instead of Object.
$Collection->first( function($model) {
if(!$model) return false;
return $model->type == 'Test';
});
I just got it working. The first() method's argument closure is provided with 2 variables. First one is the key and second one is the model. So, you will call first() method like below and if it satisfies the criteria you defined, just return true.
$result = $collection->first( function($i, $model) {
// define criteria and return true if it satisfies. The model will now be returned in resulting Collection.
});
I'm doing a join between two tables using the doctrine that comes bundled in the current symfony release. This is my controller code:
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Acme\GearDBBundle\Entity\TbGear;
use Acme\GearDBBundle\Entity\TbDships;
class DefaultController extends Controller
{
public function indexAction()
{
$repository = $this->getDoctrine()
->getRepository('AcmeGearDBBundle:TbGear');
$query = $repository->createQueryBuilder('p')
->select('p', 'q')
->innerJoin('p.fkShip', 'q', 'WITH', 'p.fkShip = q.id')
->getQuery();
$result = $query->getResult();
foreach ( $result as $p ) {
$gear[] = array('shortname' => $p->getGearShortName(), 'name' => $p->getGearName(), 'shipname' => $p->getShipName /* Does not work, since the getter is in a different entity */);
}
return $this->render('AcmeGearDBBundle::index.html.twig', array('gear' => $gear));
}
}
The query generated by this is correct and delivers the expected fields if I execute it in phpmyadmin.
SELECT t0_.GEAR_NAME AS GEAR_NAME0, t0_.GEAR_SHORT_NAME AS GEAR_SHORT_NAME1, t0_.STATUS AS STATUS2, t0_.ID AS ID3, t1_.SHIP_NAME AS SHIP_NAME4, t1_.CONTACT_NAME AS CONTACT_NAME5, t1_.CONTACT_EMAIL AS CONTACT_EMAIL6, t1_.ID AS ID7, t0_.FK_SHIP_ID AS FK_SHIP_ID8, t0_.FK_TYPE AS FK_TYPE9
FROM tb_gear t0_
INNER JOIN tb_dships t1_ ON t0_.FK_SHIP_ID = t1_.ID
AND (t0_.FK_SHIP_ID = t1_.ID)
However, I have no clue how do access those fields in the returned result set. The way I expected it to work ( by accessing the getter of the joined table entity ) does not work. The error message reads: FatalErrorException: Error: Call to undefined method Acme\GearDBBundle\Entity\TbGear::getShipName() in /var/www/symfony/src/Acme/GearDBBundle/Controller/DefaultController.php line 24
which makes sense since the TbGear entity doesn't have a getter method called getShipName() , since that's a method from the joined entity. But how do I access those values? This probably is a stupid question, but I just can't figure it out. Any help is appreciated.
$p->getFkShip()->getShipName() maybe?
This should work since it will retrieve only TbGear that satisfies you relationship. So you could be able to access to all FkShip (I suppose that is a many-to-one relation) that should be only one, and then .... you got it!
EDIT
Of course I suppose that you have correctly designed your class so that you have a getter from TbGear to access the relation with FkShip
Can you add that custom getter: getShipName()?
public function getShipName(){
if ( $this->ship != null ){
return $this->ship->getName();
}
return null; // or an empty string
}
I'm trying to delete a record in Doctrine, but I don't know why it's not deleting.
Here is my Code:
function del_user($id)
{
$single_user = $entityManager->find('Users', $id);
$entityManager->remove($single_user);
$entityManager->flush();
}
Plus: How can I echo query to see what going on here?
This is an old question and doesn't seem to have an answer yet. For reference I am leaving that here for more reference. Also you can check the doctrine documentation
To delete a record, you need to ( assuming you are in your controller ):
// get EntityManager
$em = $this->getDoctrine()->getManager();
// Get a reference to the entity ( will not generate a query )
$user = $em->getReference('ProjectBundle:User', $id);
// OR you can get the entity itself ( will generate a query )
// $user = $em->getRepository('ProjectBundle:User')->find($id);
// Remove it and flush
$em->remove($user);
$em->flush();
Using the first method of getting a reference is usually better if you just want to delete the entity without checking first whether it exists or not, because it will not query the DB and will only create a proxy object that you can use to delete your entity.
If you want to make sure that this ID corresponds to a valid entity first, then the second method is better because it will query the DB for your entity before trying to delete it.
For my understanding if you need to delete a record in doctrine that have a doctrine relationship eg. OneToMany, ManyToMany and association cannot be easy deleted until you set the field that reference to another relation equal to null.
......
you can use this for non relation doctrine
$entityManager=$this->getDoctrine()->getManager();
$single_user=$this->getDoctrine()->getRepository(User::class)->findOneBy(['id'=>$id]);
$entityManager->remove($single_user);
$entityManager->flush();
but for relation doctrine set the field that reference to another relation to null
$entityManager=$this->getDoctrine()->getManager();
$single_user=$this->getDoctrine()->getRepository(User::class)->findOneBy(['id'=>$id]);
{# assume you have field that reference #}
$single_user->setFieldData(null);
$entityManager->remove($single_user);
$entityManager->flush();
do you check your entity as the good comment annotation ?
cascade={"persist", "remove"}, orphanRemoval=true
In a Silex route I do like this, in case it helps someone:
$app->get('/db/order/delete', function (Request $request) use ($app) {
...
$id = $request->query->get('id');
$em = $app['orm.em']; //or wherever your EntityManager is
$order = $em->find("\App\Entity\Orders",$id); //your Entity
if($order){
try{
$em->remove($order);
$em->flush();
}
catch( Exception $e )
{
return new Response( $e->getMessage(), 500 );
}
return new Response( "Success deleting order " . $order->getId(), 200 );
}else{
return new Response("Order Not Found", 500);
}
}
You first need repository.
$entityManager->getRepository('Users')->find($id);
instead of
$single_user = $entityManager->find('Users', $id);
'Users' String is the name of the Users repository in doctrine ( depends if you are using Symfony , Zend . . etc ).
First, You may need to check if 'Users' is your fully qualified class name. If not check, and update it to your class name with the namespace info.
Make sure the object returned by find() is not null or not false and is an instance of your entity class before calling EM's remove().
Regarding your other question, instead of making doctrine return SQL's I just use my database (MySQL) to log all queries (since its just development environment).
try a var_dump() of your $single_user. If it is "null", it doens't exist ?
Also check if "Users" is a valid Entity name (no namespace?), and does the $id reference the PK of the user?
If you want to see the queries that are executed check your mysql/sql/... log or look into Doctrine\DBAL\Logging\EchoSQLLogger
