 * @return void
 */
public function remove(Builder $builder, Model $model)
{
    $query = $builder->getQuery();

        {
            unset($query->wheres[$key]);
            $query->wheres = array_values($query->wheres);
        }
    }
}

withChildren 方法

public function scopeWithChildren()
{
    return with(new static)->newQueryWithoutScope(new ParentScope); …
