Laravel 控制器 return 模型实例而不是数据内容

Question

我有这条路线：

Route::group(['prefix' => 'comments', 'middleware' => ['auth:api']], function(){
    Route::delete('/delete/{id}', [CommentController::class, 'destroy'])->name('comment.delete');
});

在我的控制器中我有

public function destroy(Comments $comments)
    {
        dd($comments);
    }

通常我必须有各自id的数据吧？但是我得到了模型的空实例

Answer 1

要工作，您需要将路由参数从 id 更改为 comments

Laravel automatically resolves Eloquent models defined in routes or controller actions whose type-hinted variable names match a route segment name.

Route::delete('/delete/{comments}', [CommentController::class, 'destroy'])->name('comment.delete');
