php - 无法在 Blade 中显示两列结果，laravel 5.1

Question

我试图在模板中显示两个表的列，但没有成功

模板:

@foreach ($LatestSeeker_list_adv as $ads)
    <span>ads id</span><span>{{ $ads->advertise->id }}</span>
    <span>inf id</span><span>{{ $ads->information->id }}</span>
@endforeach

Controller :

public function SeekerLatest()
{
    $LatestSeeker_list = Advertise_Model::with('information')->get();

    return view('Users.Seeker.LatestAds.index',compact('LatestSeeker_list'));
}

广告模型:

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

信息模型:

public function Advertise()
    {
        return $this->belongsTo('App\Advertise_Model');
    }

广告迁移:

Schema::table('advertise', function($table) {
            $table->foreign('information_id')->references('id')->on('information');
        });

错误:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'information.advertise__model_id' in 'where clause' (SQL: select * from information where information.advertise__model_id in (1, 2))

Answer 1

您需要定义关系列，以便 Laravel 知道需要选择哪些行来显示关系。

public function Information()
{
    return $this->hasOne('App\Information_Model', 'id', 'information_id');
}
