I am trying to get a result of query relation using relation methods in Laravel11 model
Department table has a field named parent and it’s default value is 0

I write an if statement but it always return the else result

here is my code

`class Department extends Model
{
use HasFactory;

public function members(){
    
    if($this->parent==0)
    return $this->hasManyThrough(
        Profile::class,
        Department::class,
        'parent',
        'department_id'
    );
    else 
    return $this->hasMany(Profile::class,'department_id');
}

}`
