在Laravel 7中, 资源如何只显示创建者的部分字段?

Question

在我的Laravel 7.6应用中, 我使用资源集合, 并检索了创建者, 我想在某些情况下不显示所有创建者的字段, 而只显示其中的一部分. 我在我的控件中:

$activeVotes = Vote
    ::getByStatus('A')
    ->where('votes.id', 1) 
    ->with('voteCategory')
    ->with('creator')
return (new VoteCollection($activeVotes));

在appHttpResourcesVoteCollection.php中, 我有:

<?php

namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\ResourceCollection;

class VoteCollection extends ResourceCollection
{
    public static $wrap = 'votes';

    public function toArray($request)
    {

        $this->collection->transform(function ($votes) {
            return new VoteResource($votes);
        });

        return parent::toArray($request);
    }
}

而在appHttpResourcesVoteResource.php中:

<?php

namespace App\Http\Resources;

use Illuminate\Http\Resources\Json\JsonResource;

class VoteResource extends JsonResource
{

    public static $wrap = 'votes';
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'creator' => $this->whenLoaded('creator'),
            ...

如何定义如果我需要只显示上面的一些创建者字段？

EDITED.在appHttpResourcesVoteResource.php中：如何定义如果我需要只显示上面的一些创建者的字段？

My app/User.php has :

<?php

namespace App;

use Laravel\Passport\HasApiTokens;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

use DB;
...
class User extends Authenticatable implements MustVerifyEmail
{
    use Billable;
    use HasApiTokens, Notifiable;
    use funcsTrait;
    protected $table = 'users';
    protected $primaryKey = 'id';
    public $timestamps = false;

    protected $userAvatarPropsArray = [];
    protected $avatar_filename_max_length = 255;
    protected $full_photo_filename_max_length = 255;
    protected static $password_length = 8;

    protected $fillable = [ 'username', 'email', 'status', 'provider_name', 'template_id', 'provider_id', 'first_name', 'last_name', 'phone', 'website', 'password',
    'activated_at', 'avatar', 'full_photo', 'updated_at', 'verified' ];

    protected $hidden = [ 'password', 'remember_token'  ];
    ...

    public function votes()
    {
        return $this->hasMany('App\Vote', 'creator_id', 'id');
    }
    ...

and appVote.php :

<?php

namespace App;

use DB;
use App\MyAppModel;
use Illuminate\Support\Facades\File;
use Illuminate\Support\Facades\Storage;
use App\Http\Traits\funcsTrait;
use Cviebrock\EloquentSluggable\Sluggable;
use Illuminate\Validation\Rule;

class Vote extends MyAppModel
{
    use funcsTrait;
    use Sluggable;
    use HasTags;

    protected $table = 'votes';
    protected $primaryKey = 'id';
    public $timestamps = false;

    protected $casts = [
        'meta_keywords' => 'array'
    ];

    protected $fillable = ['name', 'slug', 'description', 'creator_id', 'vote_category_id', 'is_quiz', 'status', 'image'];
    protected static $logAttributes = ['*'];
    ...
    public function creator(){
        return $this->belongsTo('App\User', 'creator_id','id');
    }

在Vote和用户模型中，有引用到其他模型.Otherwize。

   ->with('creator')

不工作.是否有一些选项我错过了？

谢谢!

我想你有两个选择。

1. 使用 hidden 在你 user 模型

通过使用 hidden在Laravel文档中, 你可以指定哪些字段会显示在你的模型的JSON或Arrray表示中.

2. 在你的模型中选择字段 with 声明

$activeVotes = Vote::getByStatus('A')->where('votes.id', 1) 
                                     ->with('voteCategory')
                                     ->with(['creator' => function ($query) {
                                         $query->select('id', 'first_name');
                                     }]);

return (new VoteCollection($activeVotes));

您需要包括的领域 id，因为这是负责加入这两个。
