Question

我正在尝试通过slug列从表注释中的列到故事表中获取数据。我已经成功地与作者合作，但我认为我必须遗漏某些东西或忘记某些东西，因为它不再有效。我收到此错误

Collection.php第1498行中的异常：此集合实例上不存在属性[comment]。

我的控制器功能

public function slug($slug){
    $menus_child = Menu::where('menu_id', 0)->with('menusP')->get();
    $stories = Story::where('slug', $slug)->get();

    $slug = $slug;

    // I used this to get the author's email going through the slug from
    // story table
    $story = Story::with('author')->where('slug', $slug)->first();
    $name = $story->author->first()->email;

    // I would like to get the name in the comment table by going through
    // the slug from the story table
    $comment = Story::with('comment')->where('slug', $slug)->get();
    $test = $comment->comment->first()->name;

    return view('open::public.single-story', compact('menus_child', 'stories', 'slug'));
}

my Comment.php

namespace App\Modules\Authors\Models;

use Illuminate\Database\Eloquent\Model;

class Comment extends Model
{
    protected $fillable = array('name', 'comment');

    protected $guarded = array('id');

    protected $table = 'comments';

    //Validation rules
    public static $rules = array(
        'name' => '',
        'comment' => ''
    );

    public function story(){
        return $this->belongsToMany('App\Modules\Authors\Models\Story', 'comment_story', 'comment_id', 'story_id');
    }
}

my Story.php

class Story extends Model
{
    protected $fillable = array('title', 'content', 'type', 'slug');

    protected $guarded = array('id');

    protected $table = 'story';

    //Validation rules
    public static $rules = array(
        'title' => '',
        'content' => '',
        'type' => ''
    );

    public function slug($title){
        $this->attributes['title'] = $title;
        $this->attributes['slug'] = Str::slug($title);
    }

    public function author(){
        return $this->belongsToMany('App\Modules\Authors\Models\Author', 'author_story', 'story_id', 'author_id');
    }

    public function comment(){
        return $this->belongsToMany('App\Modules\Authors\Models\Comment', 'comment_story', 'story_id', 'comment_id');
    }
}

Answer 1

在dparoli的帮助下，我成功了。我想不起这么久才能把它弄清楚。

我改变了

$comment = Story::with('comment')->where('slug', $slug)->get();
$test = $comment->comment->first()->name;

到

$comment = Story::with('comment')->where('slug', $slug)->first();
$test = $comment->comment->toArray();

我将测试添加到

return view('open::public.single-story', compact('menus_child', 'stories', 'slug', 'test'));

然后添加

@foreach($test as $t)
  <h1>{!! $t['name'] !!}</h1>
  <p>{!! $t['comment'] !!}
@endforeach

到我的观点

Answer 2

尝试改变这一点：

//here you get a collection of stories 
$comment = Story::with('comment')->where('slug', $slug)->get();

对此：

//here you get a single story
$comment = Story::with('comment')->where('slug', $slug)->first();

Answer 3

我给你一个不同的尝试方法

$comments = Comment::with(['story' => function ($query) {
    $query->where('slug', '=', $slug);
}])->get();

如果它适用于你想要完成的任务，那就试一试。
