How to perform a delete operation on a Model?
提问by Sylar
Coming from a Ruby on Rails experience where you load up the rails console to delete a user or all users. I am new to Laravel 5 and I am looking for something similar to delete a user already in the sqlite3 database.
来自 Ruby on Rails 体验，您可以加载 Rails 控制台以删除用户或所有用户。我是 Laravel 5 的新手，我正在寻找类似的东西来删除 sqlite3 数据库中已有的用户。
I see where people are talking about User::find(1)->delete();to delete a user but where to you put that and run in? Is there a console to perform a delete task in? I would like to know how to delete a user without dropping the table. I do not want to soft delete.
我看到人们在谈论User::find(1)->delete();删除用户的地方，但你把它放在哪里并运行？是否有控制台可以执行删除任务？我想知道如何在不删除表的情况下删除用户。我不想软删除。

You can put this code for example in controller.
例如，您可以将此代码放在控制器中。
You can use
您可以使用
$user = User::find($id);
$user->delete();
if you don't use SoftDeletingTraittrait or
如果你不使用SoftDeletingTraittrait 或
$user = User::find($id);
$user->forceDelete();
if you do, and you want to really remove user from database, not just hide it from results.
如果您这样做，并且您想真正从数据库中删除用户，而不仅仅是将其从结果中隐藏。

in Laravel 5 you can use the destroy method.
在 Laravel 5 中你可以使用 destroy 方法。
$user->destroy($id);
and, sure, you have a command line to do so.
当然，您有一个命令行可以这样做。
$ php artisan tinker
and you can run for example
你可以运行例如
>> $var = new App\User;
>> $user= $user->find($id);
>> $user->destroy();

Several ways to do this.
有几种方法可以做到这一点。
If your controller defines the user as an argument:
如果您的控制器将用户定义为参数：
public function destroy(User $user)
{
return $user->delete();
}
You can also delete any user by $id:
您还可以通过 $id 删除任何用户：
User::destroy ($id);
Assuming you're wrapping these routes with some security.
假设您以某种安全性包装这些路由。

This still works with laravel 7, i use tinkercommand line and the delete() method:
这仍然适用于 laravel 7，我使用tinker命令行和 delete() 方法：
php artisan tinker
Now i can run commands directly:
现在我可以直接运行命令：
> App\User::find($id)->delete();
