#ORM\OneToMany Is retrieving the virtual deleted entries - php

Question

I have a relation in Doctrine2 #ORM\OneToMany, suposing that i have table school and student, in the entity school i have the #ORM\OneToMany column students,
and i also have a virtual deletion column deleted_at, so every student that has the deleted_at different of null is a deleted student that is supposed not to appear in the column #ORM\OneToMany $students. How can i make this filter?
/**
* #var \Doctrine\Common\Collections\ArrayCollection
*
* #ORM\OneToMany(targetEntity="App\Oceano\Entities\Student",
* mappedBy="cartCore",
* cascade={"all"}
* )
*/
private $students;
So, when i call for school students, it is retrieving also the deleted ones.
$schoolObj->getStudents();
Any Solution using annotation or some clean change?

Answer 1

You practically described Laravel's soft deleting feature. So, if you use it, you do not need to do anything and soft deleted students will not appear. You just need to add Illuminate\Database\Eloquent\SoftDeletes trait to the Student model.
If you're using some own functionality, create a local scope in the Student model:
public function scopeNotDeleted($query)
{
return $query->whereNull('deleted_at');
}
And use it:
Student::notDeleted()->get();
Or:
$school->students()->notDeleted()->get();

You can use Criteria filter class in your entity to students collection which are not deleted
protected getStudents() {
$criteria = \Doctrine\Common\Collections\Criteria::create()
->where(\Doctrine\Common\Collections\Criteria::expr()->eq('deleted_at', null));
return $this->students->matching($criteria);
}
To get deleted students you could write it like
protected getDeletedStudents() {
$criteria = \Doctrine\Common\Collections\Criteria::create()
->where(\Doctrine\Common\Collections\Criteria::expr()->neq('deleted_at', null));
return $this->students->matching($criteria);
}
