首先，我对拉威尔不太熟悉(或者对"脏"这个词不太熟悉)
if ($this->isDirty('status')) {
if (Notification::has('website-status-' . strtolower($this->status))) {
Notification::set($this->account, 'website-status-' . strtolower($this->status), $this->emailAttributes())
->email();
}
}
And I couldn't understand what that means exactly. I tried to find out on the internet but the Laravel site only says this
"Determine if a given attribute is dirty"
这真的没用...
