推荐答案
latest()
是在Illuminate\Database\Query\Builder
类中定义的函数.它的工作非常简单.这是它的定义方式.
latest()
is a function defined in Illuminate\Database\Query\Builder
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,它将与您按descending
顺序提供的列一起为orderBy
,默认列为created_at
.
So, It will just orderBy
with the column you provide in descending
order with the default column will be created_at
.
