标签: laravel sorting directory relationship

我需要按关系langs()对文件夹($ data [' contents'])进行排序,其中lang_id == 1我该怎么做?感谢。

在模型文件夹中:

class Folder extends Model
{
    protected $fillable = ['active', 'date', 'path', 'slug'];

    public function langs()
    {
        return $this->hasMany('App\Models\LangFolder');
    }

}

在模型LangFolder中:

class LangFolder extends Model
{
    protected $fillable = ['folder_id', 'lang_id', 'name', 'description'];

    public function folder()
    {
        return $this->belongsTo('App\Models\Folder');
    }
}

在控制器中:

public function folders()
{
    // Sort folders ($data['contents']) by relationship langs() where lang_id == 1

    $data['folders'] = Folder::all();
    $data['langs'] = Lang::all();

    $directory = 'library/';
    $elements =  array_diff(scandir($directory), array('..', '.'));

    foreach($elements as $element) {
        if (is_dir($directory . '/' . $element)) {
            $content_element = Folder::where('slug', $element)->first();
            $data['contents'][] = $content_element;
        }
    }

    return view('web.library.index', compact('data'));
}

如果您想从关系中订购,则必须使用Collection代替Eloquent,例如:

$orderedLangs = $folder->langs->sortBy('lang_id');

我最后在数组中添加了关系字段“name”,并且我已将数组转换为集合,然后,我按“name”排序不区分大小写。也许还有另一种清洁解决方案。这有效:

控制器:

    foreach($elements as $element){
            if(is_dir($directory.'/'.$element)){
                $content_element = Folder::where('slug', $element)->first();
                $contenidos[] = $content_element;
            }else{
                $data['documents'][] = Document::where('path', $directory.'/'.$element)->first();
            }
        }

   foreach($contenidos as $contenido){
        foreach($contenido->langs as $lang){
            if($lang->lang_id == '1'){
                $contenido->name = $lang->name;
            }
        }
        $data['contents'][]= $contenido;
    }

$data['contents']=collect($data['contents'])->sortBy('name', SORT_NATURAL|SORT_FLAG_CASE);
