從表中顯示一列在Laravel中有很多關系

Question

我的項目在屬性和視頻之間有很多關系。 我試圖從屬性表中顯示標題，其中該標題屬於視頻表中的相應視頻。

properties (id, title)

videos (id, model_id, filename_video)

這里model_id是指向屬性表的外鍵。 使用當前代碼，我將顯示所有標題。 任何幫助表示贊賞。 這是我的代碼。

Property.php

<?php
namespace App;

use Illuminate\Database\Eloquent\Model;

class Property extends Model
{
    protected $guarded = ['id'];

    public function videos()
    {
        return $this->hasMany(Video::class, 'model_id');
    }
}

Video.php

<?php
namespace App;

use Illuminate\Database\Eloquent\Model;

class Video extends Model
{
    protected $guarded=['id'];

    public function properties()
    {
        return $this->belongsTo(Property::class);
    }

}

PropertyController.php

public function viewVideos(Property $property, Video $video)
{
    $results = DB::table('properties')
       ->join('videos', 'properties.id', '=', 'videos.model_id')
       ->select('properties.title')
       ->get();

    $video = $property->videos;

    return view('property.videos', compact('video', 'results'));
}

videos.blade.php

<h1 class="font-weight-light text-center text-lg-left mt-4 mb-0">
    Videos for 
    @foreach($results as $result)
        {{$result->title}}
    @endforeach
</h1>

Answer 1

嘗試設置如下：

Property.php

class Property extends Model
{
    protected $guarded = ['id'];

    public function video()
    {
        return $this->hasMany(Video::class);
    }
}

Video.php

class Video extends Model
{
    protected $guarded=['id'];

    public function properties()
    {
        return $this->belongsTo(Property::class, 'model_id');
    }
}

調節器

$results = Property::with('videos')->where('title', $property->title)->get();

Answer 2

你應該試試這個：

$results = DB::table('properties')
       ->join('videos', 'properties.id', '=', 'videos.model_id')
       ->pluck('title');
