Php Laravel有很多没有返回任何结果-没有'；我甚至都不怀疑？

我是拉雷维尔的新手，在过去的几个小时里我一直在拉扯头发。 我有一个现有的网站，我正试图转换成Laravel，第一步是为它建立一个API

我有一个活动模型，每个活动都有帖子。因此，他们之间应该有一种单一的关系

以下是我目前的代码：

maintages.php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Campaigns extends Model
{
    // Define the table name for this model
    protected $table = 'campaign_accounts';
    protected $primaryKey = 'id';

}

namespace App;

use Illuminate\Database\Eloquent\Model;

class CampaignPosts extends Model
{
    // Define the table name for this model
    protected $table = 'campaign_posts';
    protected $primaryKey = 'id';

}

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use DB;
use App\CampaignPosts;

DB::enableQueryLog();

class CampaignsController extends Controller
{

    public function index()
    {
        return \App\Campaigns::all();
    }

    public function show($id)
    {
        $campaigns = \App\Campaigns::find($id);
        $campaignposts = $campaigns->campaignPosts;
        dd(
            $campaignposts
        );

        return array(
            'status' => 'OK',
            'data' => array(
                'campaign' =>$campaigns,
                'posts' => $campaignposts
            )
        );
    }

    // Define relationship to CampaignPost
    public function campaignPosts()
    {
        // First key is foreign key, second key is local key
        return $this->hasMany('App\CampaignPosts', 'accountid', 'accountid');
    }
}

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Campaigns;

class CampaignPostsController extends Controller
{
    // Define relationship to CampaignPost
    public function campaigns()
    {
        // First key is foreign key, second key is local key
        return $this->belongsTo('App\Campaigns', 'accountid', 'accountid');
    }
}

activityposts.php

namespace App;

use Illuminate\Database\Eloquent\Model;

    // Define the table name for this model
    protected $table = 'campaign_accounts';
    protected $primaryKey = 'id';

    public function show($id)
    {
        $campaigns = \App\Campaigns::find($id);
        $campaignposts = $campaigns->campaignPosts;
        dd(
            $campaignposts
        );

        return array(
            'status' => 'OK',
            'data' => array(
                'campaign' =>$campaigns,

        return $this->belongsTo('App\Campaigns', 'accountid', 'accountid');
    }

        return array(

                'campaign' =>$campaigns,

        );
    }

        // First key is foreign key, second key is local key
        return $this->belongsTo('App\Campaigns', 'accountid', 'accountid');
    }
}

活动PostsController.php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Campaigns extends Model
{
    // Define the table name for this model
    protected $table = 'campaign_accounts';
    protected $primaryKey = 'id';

}

namespace App;

use Illuminate\Database\Eloquent\Model;

class CampaignPosts extends Model
{
    // Define the table name for this model
    protected $table = 'campaign_posts';
    protected $primaryKey = 'id';

}

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use DB;
use App\CampaignPosts;

DB::enableQueryLog();

class CampaignsController extends Controller
{

    public function index()
    {
        return \App\Campaigns::all();
    }

    public function show($id)
    {
        $campaigns = \App\Campaigns::find($id);
        $campaignposts = $campaigns->campaignPosts;
        dd(
            $campaignposts
        );

        return array(
            'status' => 'OK',
            'data' => array(
                'campaign' =>$campaigns,
                'posts' => $campaignposts
            )
        );
    }

    // Define relationship to CampaignPost
    public function campaignPosts()
    {
        // First key is foreign key, second key is local key
        return $this->hasMany('App\CampaignPosts', 'accountid', 'accountid');
    }
}

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Campaigns;

class CampaignPostsController extends Controller
{
    // Define relationship to CampaignPost
    public function campaigns()
    {
        // First key is foreign key, second key is local key
        return $this->belongsTo('App\Campaigns', 'accountid', 'accountid');
    }
}

当我导航到/magnities/时，所有的活动都显示良好，但是当我导航到magnities/{id}时，我只得到活动本身的结果，我无法从底层的活动帖子中获得任何信息

我尝试使用DB查询记录器，但看起来似乎没有对campaign_posts表执行任何查询，什么都没有发生

有什么想法吗？这快把我逼疯了

谢谢

关系方法应该转向自模型

namespace App;

use Illuminate\Database\Eloquent\Model;

class Campaigns extends Model
{
    // Define the table name for this model
    protected $table = 'campaign_accounts';
    protected $primaryKey = 'id';

    // Define relationship to CampaignPost
    public function campaignPosts()
    {
        // First key is foreign key, second key is local key
        return $this->hasMany('App\CampaignPosts', 'accountid', 'accountid');
    }

}

及

您需要将关系代码放入模型中
