这个方法使用了两个Eloquent的方法。首先,我们使用orderBy方法按照主键id的降序对记录进行排序。然后,我们使用first方法获取排序后的第一条记录,也就是最后一条记录。 使用latest和first方法 $lastRecord=YourModel::latest()->first(); 这个方法使用了latest方法,它会根据模型的created_at列进行排序,按照最新的记录顺...
要获取最后一条记录,可以使用Laravel的查询构建器或Eloquent ORM提供的方法。以下是使用Eloquent ORM的示例代码: 代码语言:txt 复制 $lastRecord = YourModel::latest()->first(); 上述代码中,YourModel是你的模型类名,可以替换为你实际使用的模型类名。latest()方法用于按照模型的时间戳字段(通常是created_at或upd...

在Laravel 中获取 FIND_IN_SET 的最新更新记录,可以通过使用 Eloquent ORM 和查询构建器来实现。 首先,确保你已经在 Laravel 项目中配置好了数据库连接。然后,创建一个模型来表示你要查询的数据表。假设你的数据表名为 records,你可以创建一个名为 Record 的模型。 代码语言:txt 复制 <?php namespace ...

Instead, a deleted_at timestamp is set on the record. To enable soft deletes for a model, apply the SoftDeletingTrait to the model:use Illuminate\Database\Eloquent\SoftDeletingTrait; class User extends Eloquent { use SoftDeletingTrait; protected $dates = ['deleted_at']; }...
