laravel中latest()的作用是什么?

What is the function of latest() in laravel?

示例:

public function activity()
{
    return $this->hasMany('AppActivity')
        ->with(['user', 'subject'])
        ->latest();
}

我一直在看 Laravel 文档，但我找不到它...

I've been looking in the laravel documentation, but I couldn't find it...

latest() 是一个定义在 IlluminateDatabaseQueryBuilder 类中的函数.它的工作非常简单.这是它的定义方式.

latest() is a function defined in IlluminateDatabaseQueryBuilder Class. It's job is very simple. This is how it is defined.

public function latest($column = 'created_at')
{
    return $this->orderBy($column, 'desc');
}

因此，它只会 orderBy 与您以 descending 顺序提供的列一起使用，默认列将是 created_at.

So, It will just orderBy with the column you provide in descending order with the default column will be created_at.
