Reference setting value in entity symfony

I have a doubt about code organization using symfony3 and doctrine: I'll try to explain as clear as I can. Let's say I have a FootballClub entity:

class FootballClub

// other code
private $memberships;

public function addMembership(Membership $membership) : FootballClub

$this->memberships = $membership;
return $this;



public function removeMembership(Membership $membership) : bool

return $this->memberships->removeElement($membership);




The entity is in a many-to-one relationship with another entity, Membership, which represents the contract a player has with the club. Let's say each club
has only a limited number of membership it can acquire, number that is represented as a setting, for example, as a property in a Setting entity.
The question is: how should I reference that setting when removing a membership from the club and check that is respected? Entities should not have any dependency, so what would be the correct way to implement this? A service? can you provide an example? Thank you for your time.

You could create a Settings entity, linked in OneToOne relation with FootballCluc entity.

Settings

OneToOne

FootballCluc

Define Settings like this and instanciate it in the FootballClub's constructor

FootballClub

Settings entity

/** @Entity */
class Settings

/**
* @ORMId
* @ORMGeneratedValue
* @ORMColumn(type="integer")
*/
private $id;

/**
* @ORMColumn(type="integer")
*/
private $maxMembership;

// Other configurable properties ...

__constructor($maxMembership = 50)

$this->maxMembership = $maxMembership;


public function getMaxMembership()

return $this->maxMembership;


public function setMaxMembership($maxMembership)

$this->maxMembership = $maxMembership;




Football Entity

class FootballClub


/**
* One FootballClub has One Settings.
* @OneToOne(targetEntity="Settings")
* @JoinColumn(name="settings_id", referencedColumnName="id")
*/
private $settings;

// other code
private $memberships;

__constructor(Settings $settings = null)

if (null === $settings)
$settings = new Settings();

$this->settings = $settings;


public function addMembership(Membership $membership) : FootballClub

if ($this->settings->getMaxMembership() <= count($this->memberships))
// throw new Exception("Max number of membership reached"); Strict mode
// return false // soft mode

$this->memberships-> = $membership;
return $this;



public function removeMembership(Membership $membership) : bool

return $this->memberships->removeElement($membership);




setSettings

nullable
