Laravel雄辩地更改属性名称

Question

I have a group attribute in my model and I want to change the group attribute to sub-group if the group parent is not 0.

My code:

public function setGroupAttribute
{
    $group_id = $this->attribute['id'];

    $group = Group::find($group_id);

    if ($group->parent != 0)
    {
        $this->attribute['group'] = 'sub-group';
    }
}

But I guess what I'm doing is wrong? So how do I do this right? I just want to change the attribute and not the data inside.

You are setting $this->attribute['group'] to a string of 'sub-group' rather than re-indexing it. Try this instead...

$this->attribute['sub-group'] = $this->attribute['group'];
unset($this->attribute['group']);
