Php Filament v3：具有 hasMany 和 BelongsTo 的关系管理器

我正在学习长丝，但我被关系经理困住了:

我有两张桌子: 有两个冒号:ID和NOM "USERS"，有5个冒号:ID、姓名、邮箱、密码、Eablissement_id

我试着设置我的关系经理如何在文档中写，但我没有成功.

我的代码是:

模型建立

class etablissements extends Model
{
    use HasFactory;

    protected $table = 'etablissements';

    protected $fillable = [
        'nom',
    ];

    public function users(){
        return $this->hasMany(User::class, 'etablissement_id');
    }
}

模型用户:

class User extends Authenticatable
{
    use HasApiTokens, HasFactory, Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array<int, string>
     */
    protected $fillable = [
        'name',
        'email',
        'password',
    ];

    /**
     * The attributes that should be hidden for serialization.
     *
     * @var array<int, string>
     */
    protected $hidden = [
        'password',
        'remember_token',
    ];

    /**
     * The attributes that should be cast.
     *
     * @var array<string, string>
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
        'password' => 'hashed',
    ];

    public function etablissement(){
        return $this->belongsTo(Etablissement::class);
    }
}

UsersRelationManager.php:

class UsersRelationManager extends RelationManager
{
    protected static string $relationship = 'users';

    public function form(Form $form): Form
    {
        return $form
            ->schema([
                Select::make('author_id')
                    ->label('Author')
                    ->options(User::all()->pluck('name', 'id'))
                    ->searchable()
            ]);
    }

    public function table(Table $table): Table
    {
        return $table
            ->recordTitleAttribute('name')
            ->columns([
                Tables\Columns\TextColumn::make('name'),
            ])
            ->filters([
                //
            ])
            ->headerActions([
                Tables\Actions\CreateAction::make(),
            ])
            ->actions([
                Tables\Actions\EditAction::make(),
                Tables\Actions\DeleteAction::make(),
            ])
            ->bulkActions([
                Tables\Actions\BulkActionGroup::make([
                    Tables\Actions\DeleteBulkAction::make(),
                ]),
            ])
            ->emptyStateActions([
                Tables\Actions\CreateAction::make(),
            ]);
    }
}

问题是，当我创建一个新的机构时，我必须 Select 一个(或多个)将连接到该机构的用户.一个用户只能链接到1个机构. 但是，当我将我的用户连接到机构时，该脚本将创建一个新用户，而不是 Select 一个现有用户.

我放了一些推荐信: edditing page for establishment个

it offers me the users个

But when i click on "create" the script create a new user instead of modify the etablissement_id of my user that i choose个

为了获得信息，我与以下人员一起工作:

我试着阅读文档，查看其他代码，但一无所获
