Laravel 6 : Duplicate database entry on polymorphisme relation save - php

Question

I try to save a morph relationship in my database, but when i try to save it I Have tow entry in every table use for the relation.
here is my client class
class Client extends Model
{
protected $guarded = [];
public function clientelle(){
return $this->morphTo();
}
}
my particulier class
class Particulier extends Model
{
protected $guarded = [];
public function client(){
return $this->morphOne(Client::class,'clientelle');
}
}
So when I try to save like that :
$particulier = new Particulier();
$particulier->nom = $request->nom;
$particulier->prenom = $request->prenom;
$particulier->save();
$particulier->client()->create(['telephone'=>$request->telephone,'adresse'=>$request->adresse,'email'=>$request->email]);
My database save two same recorde. Here is my problem.
So I have try diffrente thing to avoid it but I have error every time
delete $particulier->save(); but SQL error id don't exist
replace create([...]) by save([...]) or sync([...]) but don't work
Thank you in advance

So I have finally find a worst solution...
In your controller add int var and init it to 0 like that :
Private $checkDouble=0;
In place where you want save your relation create if block and put in all of your model save like that :
if($this->checkDouble==0) {
$this->checkDouble = $this->checkDouble + 1; //Increase your var value
$particulier = Particulier::create(['nom' => $request->nom, 'prenom' => $request->prenom]);
$particulier->client()->create(['telephone' => $request->telephone, 'adresse' => $request->adresse, 'email' => $request->email]);
}
And no more duplicate data
I know is really worst solution but I don't see any best solution ^^
