Laravel 缺少 [Route: destroy] 所需的参数。

Posted 2021-04-10

reports

Route::resource('reports/', 'ReportController')->middleware('auth');

destroy

DELETE    | reports/{}             | destroy          | AppHttpControllersReportController@destroy  

在index.blade.php中，我创建了一个删除按钮，如下所示。

<form method="post" action="{{route('destroy',['report'=>$report->id])}}" onsubmit="return confirm('Are you sute to delete?')">
             @csrf 
             @method("delete")
             <button type="submit" class="btn btn-danger btn-sm">Delete</button>
 </form>

ReportController Destroy方法。

public function destroy(Report $report)
{
     //
}

但我得到以下错误信息

Missing required parameters for [Route: destroy] [URI: reports/{}].

答案

到

Route::resource('reports/', 'ReportController')->middleware('auth');

检查

Route::resource('reports', 'ReportController')->middleware('auth');

文档

另一答案

而模型Report必须被添加到RouteServiceProvider. php中，就像这样。

DELETE    | reports/{report}             | destroy          | AppHttpControllersReportController@destroy 

这是路由模型绑定。阅读这里

public function boot()
{
    parent::boot();

    Route::model('report', AppReport::class);
