Question

我对此感到困惑：我正在尝试以某种博客格式构建一些多语言支持。我有一些帖子（我称之为新闻）我需要两种语言。我现在拥有的是语言表和新表。

语言 - ID - 名称 - 代码

newss - ID - parent_id - lang_id - slu .. - 标题 - 身体

到目前为止一切正常。我可以将新闻保存到数据库中。唯一令人讨厌的问题是在索引新闻页面中我无法获得语言代码。我有一个带有{{$ news-＆gt; language-＆gt; code}}的foreach循环，它检索“试图获取非对象的属性”。

我会与你分享我的模特，控制器和观点，希望有人可以为我所看到的错误带来一些启示。

型号：

Languages.php

<?php

class Language extends Eloquent {

    protected $fillable = array('name', 'code');

    public static $rules = array(
        'name'=>'required|min:3', 
        'code'=>'required|min:2'
    );

    public function news() {
        return $this->hasMany('News');
    }
}

News.php

<?php

class News extends Eloquent {

    protected $fillable = array('parent_id', 'lang_id', 'slug', 'title', 'body');

    protected $table = 'newss';

    public static $rules = array(
        'parent_id'=>'integer',
        'lang_id'=>'required|integer',
        'title'=>'required|min:3'

    );

    public function language() {
        return $this->belongsTo('Language');
    }

    public function parent_news() {
        return $this->belongsTo('News','parent_id');
    }

    public function child_news() {
        return $this->hasMany('News','parent_id');
    }

}

控制器：

NewsController.php

public function index()
    {

        $newss = News::all();

        $languages = array();
        foreach(Language::all() as $language) {
            $languages[$language->id] = $language->code;
        }

        return View::make('admin.news.index')
            ->with('newss', $newss)
            ->with('languages', $languages);
    }

查看：

@foreach($newss as $news)  
    <tr class="gradeA">
            <td>{{ $news->title}}</td>
            <td>{{ $news->language->code}}</td>
            <td>{{ HTML::linkRoute('admin.news.edit', '', array($news->id), array('class' => 'btn btn-warning btn-circle glyphicon glyphicon-pencil')) }}</td>
            <td>{{ Form::open(['method' =>'DELETE', 'route'=>['admin.news.destroy', $news->id], 'class'=>'form-inline']) }}
            {{ Form::hidden('id', $news->id) }}
            {{ Form::button('<i class="fa fa-times"></i>', array('type' => 'submit', 'class' => 'btn btn-danger btn-circle')) }}
            </td>
            {{ Form::close() }}
     </tr>
@endforeach
