Question

我是Laravel的初学者。

我有标准的登录用户模型（由Laravel生成）：

class UploadedFiles extends Model
{
    protected $quarded = [];
    protected $fillable = ['company_id', 'enable', 'photoable_type', 'photoable_id', 'path', 'ip', 'number'];
    protected $table = 'uploaded_files';


}


class User extends Authenticatable implements MustVerifyEmail
{
    use Notifiable;
    use psCMS\Presenters\UserPresenter;

    public static $roles = [];

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */

    protected $fillable = ['company_id', 'enable', 'name', 'surname', 'email', 'email_verified_at', 'password', 'counter', 'url_address',  'isCompany', 'isMailing', 'content', 'nip1', 'business1', 'phone1', 'street1', 'number1', 'postal_code1', 'city1', 'country_id1', 'provincial_id1', 'nip2', 'business2', 'phone2', 'street2', 'number2', 'postal_code2', 'city2', 'country_id2', 'provincial_id2', 'nip3', 'business3', 'phone3', 'street3', 'number3', 'postal_code3', 'city3', 'country_id3', 'provincial_id3', 'cash', 'lng', 'lat', 'enable_map', 'remember_token', 'created_at', 'updated_at', 'last_login_at', 'last_login_ip' ];


    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];


    public function roles()
    {
        return $this->belongsToMany('App\Role');
    }

    public function mainRole()
    {
        return $this->hasOne('App\Role');
    }

    public function comments()
    {
        return $this->hasMany('App\Comments');
    }


    public function images()
    {   // find(['photoable_type', '=', 'AdminImage'] ::with('director')->get();
        return $this->hasMany('App\UploadedFiles' );
    }

    public function images2()
    {   // ->where('photoable_type', 'AdminImage')
        return $this->hasManyThrough('App\UploadedFiles', 'App\User', 'photoable_id', 'id');
    }

    public function hasRole(array $roles)
    {

        foreach($roles as $role)
        {

            if(isset(self::$roles[$role]))
            {
                if(self::$roles[$role])  return true;

            }
            else
            {
                self::$roles[$role] = $this->roles()->where('name', $role)->exists();
                if(self::$roles[$role]) return true;
            }

        }
        return false;
    }

    public function loginHistory()
    {
        return $this->hasMany('App\UserLoginHistory');
    }

    public function companies()
    {
        return $this->belongsTo('App\Companies','company_id');
    }



}

我的模式：

Schema::create('users', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->bigInteger('company_id')->unsigned();
            $table->foreign('company_id')->references('id')->on('companies')->onDelete('cascade');
            $table->boolean('enable')->default(0);
            $table->string('name', 120)->nullable();
            $table->string('surname', 120)->nullable();
            $table->string('email', 120)->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->bigInteger('counter')->default(0);
            $table->string('url_address', 160);
            $table->boolean('isCompany')->default(0);
            $table->boolean('isMailing')->default(0);
            $table->text('content')->nullable();
            $table->string('nip1', 12)->nullable();

            $table->bigInteger('country_id1')->default(0);
            $table->bigInteger('provincial_id1')->default(0);
            $table->string('nip2', 12)->nullable();
            $table->string('business2', 120)->nullable();

            $table->bigInteger('country_id2')->default(0);
            $table->bigInteger('provincial_id2')->default(0);
            $table->string('nip3', 12)->nullable();
            $table->string('business3', 120)->nullable();
            $table->string('phone3', 60)->nullable();
            $table->string('street3', 150)->nullable();
            $table->string('number3', 8)->nullable();

            $table->rememberToken();
            $table->timestamps();
            $table->engine = "InnoDB";
        });




Schema::create('role_user', function (Blueprint $table) {
            $table->bigInteger('user_id')->unsigned();
            $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
            $table->bigInteger('role_id')->unsigned();
            $table->foreign('role_id')->references('id')->on('roles')->onDelete('cascade');
            $table->engine = "InnoDB";
        });



Schema::create('roles', function (Blueprint $table) {

            $table->string('photoable_type', 150);
            $table->integer('photoable_id');
            $table->string('path', 255);
            $table->string('ip', 25);
            $table->bigInteger('number')->default(0);
            $table->timestamps();
            $table->engine = "InnoDB";
        });

我在数据库中有以下记录： https://ibb.co/ZhHGkKX

INSERT INTO `uploaded_files` (`id`, `company_id`, `enable`, `photoable_type`, `photoable_id`, `path`, `ip`, `number`, `created_at`, `updated_at`) VALUES
(46, 1, 1, 'AdminImage', 1, 'upload/images/AdminImage/627e653871183f639c8d9460f37111b1.jpg', '172.29.0.1', 0, '2019-05-27 08:50:08', '2019-05-27 08:50:08');
COMMIT;

在我的基地里，我有关系： -upload_files.photoable_id = User.id

我需要显示属于用户的所有具有photoable_type = AdminImage的图像

我该怎么做？请帮助

Answer 1

只需添加用户模型

public function images2()
{   
    return $this->hasMany('App\UploadedFiles', 'company_id','company_id');
}

public function AdminImage()
{  
    return $this->images2()->where('photoable_type','=','AdminImage');
}

现在您可以访问所有具有photoable_type = AdminImage的用户

User::with('AdminImage')->get();

Answer 2

您已经在用户模型中声明了正确的方法，因此请尝试对其进行修改：

 public function images()
{   
    // App\UploadedFiles must be a model
    return $this->hasMany(App\UploadedFiles::class, 'photoable_id', 'id');
}

使用以下关系：

User::with('images')->get();
