recursive symfony 3.4 complex form embed - symfony

Question

Having this schema:
I Would like make a form like that
I don't know how can I build the form.
A company haves many persons.
In a company we have a corporate hierarchy : employee, boss, subordinate
A worker can have subordinate worker It's why I have added a recurve link inside company_person for parent child notion link.
The Role is here for saying what is the role of the worker.
Company
class Company
{
/**
* #ORM\Column(type="string", length=45, nullable=true)
*/
private $name;
/**
* #ORM\OneToMany(targetEntity="CompanyPerson", mappedBy="company")
*/
private $companypersons;
}
Person
class Person
{
/**
* #ORM\Column(type="string", length=45, nullable=true)
*/
private $name;
/**
* #ORM\OneToMany(targetEntity="CompanyPerson", mappedBy="person", cascade={"persist"})
* #var ArrayCollection
*/
private $companypersons;
}
Status
class Status
{
/**
* #ORM\Column(type="string", length=45, nullable=true)
*/
private $libelle;
/**
* #ORM\OneToMany(targetEntity="CompanyPerson", mappedBy="statut")
*/
protected $companypersons;
}
CompanyPerson
class CompanyPerson
{
/**
* #ORM\Column(type="datetime", nullable=true)
*/
private $dateAdded;
/**
* #ORM\ManyToOne(targetEntity="Company", inversedBy="companypersons",
cascade={"persist"})
*/
private $company;
/**
* #ORM\ManyToOne(targetEntity="Person",
inversedBy="companypersons", cascade={"persist"})
*/
private $person;
/**
* #ORM\ManyToOne(targetEntity="Status",
inversedBy="companypersons", cascade={"persist"})
*/
private $status;
/**
* #ORM\ManyToOne(targetEntity="CompanyPerson", inversedBy="childrens")
*/
private $parent;
/**
* #ORM\OneToMany(targetEntity="CompanyPerson", mappedBy="parent")
*/
private $childrens;
public function __construct(Company $companay= null, Person $person =
null, CompanyPerson $parent = null, Status $status = null)
{
$this->companay = $companay;
$this->person = $person;
$this->parent = $parent;
$this->status = $status;
$this->childrens = new ArrayCollection();
}
}
I worked on embed form with collections, but I can not create this form, because it is't very complex for me.

Answer 1

You have rational problems in your mapping. you should use the parent-children pattern inside Person , not CompanyPerson. a CompanyPerson here, is a joint-entity. It is there to persist things like:
$dateAdded : the date at which a relation between a Company and a Person and an Status was stablished.
Person
class Person
{
/**
* #ORM\Column(type="string", length=45, nullable=true)
*/
private $name;
/**
* #ORM\OneToMany(targetEntity="CompanyPerson", mappedBy="person", cascade={"persist"})
* #var ArrayCollection
*/
private $companypersons;
/**
* #ORM\ManyToOne(targetEntity="Person", inversedBy="childrens")
*/
private $parent;
/**
* #ORM\OneToMany(targetEntity="Person", mappedBy="parent")
*/
private $children;
}
Note to keep children without s, as it is already in plural form.
Also keep in mind to use cascade operations on mapping definition on the inverse side of association. So the
class CompanyPerson
{
/**
* #ORM\ManyToOne(targetEntity="Company", inversedBy="companypersons", cascade={"persist"})
*/
private $company;
/**
* #ORM\ManyToOne(targetEntity="Person", inversedBy="companypersons", cascade={"persist"})
*/
private $person;
}
should be
class CompanyPerson
{
/**
* #ORM\ManyToOne(targetEntity="Company", inversedBy="companypersons")
*/
private $company;
/**
* #ORM\ManyToOne(targetEntity="Person", inversedBy="companypersons")
*/
private $person;
}
Your Question
To get around the so called, complex form! you may use mapped=false setting attribute in your fields. using this, you may tell the symfony that this field, is not mapped to a property of the target entity of your form.
In your case you have CompanyType form (with Company as target entity) and want to create all those stuff in one go! So you may add unmapped fields to your form and capture theme inside your controller and parse theme as you wish.
Using this method, you should create joint-entities (like Company-Person) by your self (again inside your controller).
