Laravel Eloquent delete by id
提问by Sam
I'm trying to delete a single record by id. Instead, it deletes all records in that table.
我正在尝试按 id 删除单个记录。相反，它会删除该表中的所有记录。
Here's my code:
这是我的代码：
View
看法
<form role="form" action="{{ route('status.delete', ['statusId' => $status->id]) }}" method="post">
<button type="submit" class="btn btn-default"><i class="fa fa-times"></i> Delete</button>
<input type="hidden" name="_token" value="{{ Session::token() }}">
</form>
Routes
路线
Route::post('/status/{statusId}/delete', [
'uses' => '\Dashboard\Http\Controllers\StatusController@deleteStatus',
'as' => 'status.delete',
'middleware' => ['auth'],
]);
Controller
控制器
public function deleteStatus(Request $request, $statusId)
{
Auth::user()->statuses()->delete($statusId);
return redirect()->route('home')->with('success', 'Post deleted.');
}
Note:When I dd($statusId)it does provide the right ID for the status I'm deleting. So that part does work.
注意：当我dd($statusId)确实为我正在删除的状态提供了正确的 ID 时。所以那部分确实有效。

Unfortunately, the Eloquent builder does not support passing the id to delete.
不幸的是，Eloquent 构建器不支持将 id 传递给delete.
Instead, you have to first find to model, then call deleteon it:
相反，您必须首先找到模型，然后调用delete它：
$request->user()->statuses()->findOrFail($statusId)->delete();

This is possible in Laravel 5.6 using the destroy method:
这在 Laravel 5.6 中使用 destroy 方法是可能的：
From the docs:
从文档：
However, if you know the primary key of the model, you may delete the model without retrieving it. To do so, call the destroy method
但是，如果您知道模型的主键，则可以删除模型而不检索它。为此，请调用 destroy 方法
App\Model::destroy(1);
or to delete an array of ids:
或删除一组 id：
App\Model::destroy([1, 2, 3]);
or by query:
或通过查询：
App\Model::where('active', 0)->delete();
