访问雄辩属于许多在树枝？

我有一个关于口才的问题，并将它们加载到树枝模板中。我有三个表格，分别是文章，用户和作者。第一个也很直接，他们是我的博客帖子（文章），用户是我的用户模型，包含名字，姓氏，电子邮件等。作者是一个数据透视表，其中包含（users_id和articles_id），它与前两个表中的id相对应。访问雄辩属于许多在树枝？

我遇到的问题是我如何使用下面的数组显示作者的名字和枝条标记。此刻我有这个，但它只是不工作。

{% for article in articles %} 
by {{ article.first_name }} {{ article.last_name }} 
{% end for %}

任何帮助将是伟大的，我一直试图找出这几天。

我的代码

我有以下关系

class Article extends Eloquent { 

    public function authors() { 
     return $this->belongsToMany('voicetank\User\User', 'ArticleAuth', 'Articles_id', 'users_id'); 
    } 
} 

class User extends Eloquent { 
    public function articles() { 
     return $this->belongsToMany('voicetank\Articles\AddArticle', 'ArticleAuth', 'users_id', 'id'); 
}

在我的路线，我有以下代码

$app->get('/home', function() use ($app) { 

$articles = $app->article->where('articlepublish', true)->orderBy('created_at', 'desc')->with('authors')->get(); 

$user = $app->user->get(); 

$app->render('home/home.php', [ 
    'articles' => $articles, 
    'user' => $user 
]);

使用的var_dump我碰到下面的阵列。

通过定义作者为Article一个belongsToMany它会给你一个数组。您的查询检索你想，但在你的模板中的数据，如果只有一个作者，你应该做的：如果你想每个作者都有自己的

对于多位作者：

{% for article in articles %} 
by {{ article.authors[0].first_name }} {{ article.authors[0].last_name }} 
{% end for %}

UPDATE “通过”行，你可以这样做：

{% for article in articles %} {% for author in authors %} by {{ author.first_name }} {{ author.last_name }} {% end for %} {% end for %}

或者，如果你希望他们全部是由用逗号分隔线相同则可能是：

{% for article in articles %} by {% for author in authors %} {{ author.first_name }} {{ author.last_name }}{% if not loop.last %}, {% endif %} {% end for %} {% end for %}

就是这样，谢谢埃里克。 –

嗨，埃里克，还有一个问题。我将如何去为多个作者进行构造？ –

更新了回复，让我知道这是否适合你 –
