我在雄辩的关系中遇到问题，并将它们加载到树枝模板中。我有三个表，文章，用户和作者。第一个也很直接他们是我的博客文章（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），它对应于前两个表中的id。
我遇到的问题是如何使用带有树枝标记的以下数组来显示作者的姓名。目前我有这个，但它只是不起作用。
{% for article in articles %}
by {{ article.first_name }} {{ article.last_name }}
{% end for %}
任何帮助都会很棒，我一直试图解决这个问题。
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');
}
在我的路线中，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var_dump我得到以下数组。
object(Illuminate\ Database\ Eloquent\ Collection) #199 (1) { ["items":protected]= >
array(1) {
[0] => object(voicetank\ Articles\ AddArticle) #194 (23) { ["table":protected]= >

通过将作者定义为belongsToMany Article，它将为您提供一个数组。您的查询正在检索您想要的数据，但如果只有一位作者应该在您的模板中检索：
{% for article in articles %}
by {{ article.authors[0].first_name }} {{ article.authors[0].last_name }}
{% end for %}
<强>更新
对于多位作者，如果您希望每位作者都有自己的“by”行，您可以这样做：
{% for article in articles %}
{% for author in authors %}
by {{ author.first_name }} {{ author.last_name }}
{% end for %}
{% end for %}
或者，如果您希望它们全部按逗号分隔，则可以是：
{% for article in articles %}
by
{% for author in authors %}
{{ author.first_name }} {{ author.last_name }}{% if not loop.last %}, {% endif %}
{% end for %}
{% end for %}
