Question

我正在建立一个论坛，用户可以在这个论坛中创建主题并留下回复。

我建立了一个如下所示的关系。但是，当我保存文章时，topic_id没有附加。我认为saveReply方法是错误的。

此外，在这种情况下，如何将特定帖子的注释传递给show方法中的视图？

我是一个菜鸟，所以如果我的问题含糊不清，我很抱歉，但任何帮助都将不胜感激!!

    Route::post('forums', 'ForumsController@store');
    Route::get('forums/{category_id}/{title}','ForumsController@show');
    Route::post('forums/{category_id}/{title}', 'ForumsController@saveReply');

});

       return view('forums.index',compact('categories','topics'));
    }

    public function create()

Answer 1

Request::all返回所有输入的数组，所以当你这样做时：

new Comment($category_id,$request->all())

你会得到这样的东西：

1['some' => 'thing', 'other'=> 'values']

这可能是问题所以请尝试这样做：

new Comment(array_merge(['category_id' => $category_id ], $request->all())

在开发/本地环境中，将debug设置为true，这样您就可以获得有意义的错误消息，以便轻松找到exect问题。

无法在评论表中附加topic_id
