我创建了一个网站，它有一个博客部分和一个视频部分。我有一个博客的配置文件，我试图与视频部分共享，但它不能正常工作，所以我为视频创建了一个单独的配置。并修改了视频
的列名 $title and $subtitle
$v_title and $v_subtitle.
但是当我这样做时，我得到以下错误
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '' for key 'videos_slug_unique'
由于某种原因没有产生一个段塞，这就导致了这个问题。这种蛞蝓在我的桌子上是独一无二的。如果我把变量改成原来的样子
$title and $subtitle
它工作，为什么呢?

在更改列名之后，动态设置器setTitleAttribute和setSubtitleAttribute不会被调用，并且段代码不会得到更新。您还需要更改setter方法的名称。
public function setVTitleAttribute($value) {
...
}
public function setVSubtitleAttribute($value) {
...
}
似乎你没有重构title到v_title在整个类。例如，您应该更改
public function setTitleAttribute($value)
{
$this->attributes['title'] = $value;
if (! $this->exists) {
$this->setUniqueSlug($value, '');
}
}
public function setVTitleAttribute($value)
{
$this->attributes['v_title'] = $value;
if (! $this->exists) {
$this->setUniqueSlug($value, '');
}
}
