Question

我想要实现的是@foreach发布所有新闻，@ foreach在另一个@foreach之间发布所有评论，并发布新闻帖中的ID。

我不确定如何将此ID传递给getNewsComments函数。

我的控制器：

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use DB;
use App\News;
use App\newsComments;


class newsController extends Controller
{
    public function getAllNews(){
        $results = News::all();
        return view('index')->with('news', $results);
    }
}

路线：

Route::get('/', 'newsController@getAllNews');

新闻模式：

class News extends Model
{
    // set table
    protected $table = 'lg_news';


    public function newsComments(){
        return $this->hasMany('App\newsCommments');
    }
}

评论模型：

class newsComments extends Model
{
    // set table name
    protected $table = 'lg_newscomments';

}

视图

@foreach ($news as $article)

  @foreach($news->$newsComments as $comment)
  @endforeach
@endforeach

错误：

未定义的变量：newsComments（查看： C：\ XAMPP \ htdocs中\资源\视图\ index.blade.php）

Answer 1

您不需要多个路线，只需要两个相互关联的表格，其中1：N关系

第（1）条 - ＆gt;评论（N）

然后，您将为每个表创建一个模型，并创建如Laravel文档中所述的关系

One to Many relationship in Laravel

然后您将获取所有帖子并将其传递给视图：

public function getAllArticles()
{
 $posts = Post::all();
 return view('view-name', $posts);
}

最后，创建一个视图并显示帖子和评论：

    @foreach($posts as $post)
     {{ $post->title }}
     {{ $post->body }}
     @foreach($post->comments as $comment)
      {{ $comment->title }}
      {{ $comment->body }}
     @endforeach
    @endforeach

提醒：$post->comments，评论是在您创建关系的模型中定义的方法名称

在web.php上定义路线：

Route::get('/', 'ControllerName@getAllArticles');

转到localhost:8000/（如果托管了网站，则转到您的网站域）以查看结果

Answer 2

更改此行：

set theSubject to "Voicemail"
set theContent to read "/private/tmp/voice.tgCrnv/BODY.txt"
set theAddress to "me@example1.com"
set theSender to "me@example2.com"
set theAttachmentFile to "/private/tmp/voice.tgCrnv/msg_1bb3b4f2-c6b1-4012-89c0-a19177cc6ca2.wav" as POSIX file as alias

tell application "Mail"
    set msg to make new outgoing message with properties ¬
        {subject:theSubject, content:theContent, visible:false, sender:theSender}
    tell msg
        make new to recipient at end of every to recipient with properties {address:theAddress}
        make new attachment at end of last character of content with properties ¬
            {file name:theAttachmentFile}
    end tell
    delay 1
    send msg
end tell

到

return view('index')->with('news', $results);

它可能会起作用。

PS：return view('index', ['news' => $results]);功能会设置一个会话！它不会传递变量来查看。
