How to show/get all data by the foreign_key - php

Question

Similiar to Post and Category, I have a database tables Penyedia and Pekerjaan. Whereby Penyedia is similiar to Category, and Pekerjaan similiar to Post. Penyedia hasMany Pekerjaans and Pekerjaan belongsTo Penyedia.
Here is the model:
Pekerjaan.php
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model as Eloquent;
class Pekerjaan extends Eloquent
{
use HasFactory;
protected $guarded = [];
public function penyedia(){
return $this->belongsTo(Penyedia::class);
}
}
Penyedia.php
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model as Eloquent;
class Penyedia extends Eloquent
{
use HasFactory;
protected $guarded = [];
public $timestamps = false;
public function pekerjaans(){
return $this->hasMany(Pekerjaan::class);
}
}
Here is the Table that shows Penyedia: (There is a button that will redirect the user to show the list of datas Pekerjaan specific to that Penyedia)
<section class="content">
<div class="container-fluid">
<div class="row">
<div class="col-12">
<div class="card">
<div class="card-header">
<h3 class="card-title">Tabel Penilaian Penyedia</h3>
</div>
<!-- /.card-header -->
<div class="card-body table-responsive">
<table id="tabelpenyedia" class="table table-bordered">
<thead>
<tr>
<th style="width: 10px">No.</th>
<th>Nama Penyedia</th>
<th>Nilai</th>
<th style="width: 120px">Aksi</th>
</tr>
</thead>
<tbody>
#php $no = 1; #endphp
#foreach ($penyedia as $penyedias)
<tr>
<td>{{$no++}}</td>
<td>{{$penyedias->nama}}</td>
<td>{{number_format($penyedias->nilai,1)}}</td>
<td>
Beri Penilaian
</td>
</tr>
#endforeach
</tbody>
</table>
</div>
<!-- /.card-body -->
</div>
<!-- /.card -->
</div>
</section>
From that table I have a button that will redirect the user to show the list of datas Pekerjaan specific to that Penyedia. Similiar to this tinker:
php artisan tinker

],
}
I have tried these two methods below in the AdminController:
//Show all Penyedia from database
public function tabelnilai_penyedia(){
$penyedia = penyedia::all();
return view('admin.datanilai_penyedia', compact('penyedia'));
}
//Get Pekerjaan specific to the Penyedia
public function showpekerjaan(Penyedia $penyedia){
$pekerjaans = Penyedia::where('id', $penyedia->id)->get();
$penyedia = Penyedia::with('pekerjaans')->get();
return view('admin.showpekerjaan', compact('penyedia'))->with('pekerjaans',$pekerjaans);
}
tabelnilai_pekerjaan.php (This is the table that I want to show, it's get data based on the 'Penyedia')
<section class="content">
<div class="container-fluid">
<div class="row">
<div class="col-12">
<div class="card">
<div class="card-header">
<h3 class="card-title">Tabel Nilai Pekerjaan</h3>
</div>

Answer 1

Assumption : You want to find all pekerjaans assosicated to penyedia and you get the correct id of penyedia in $penyedia->id
Hope this help you
inside AdminController:
public function showpekerjaan(Penyedia $penyedia){
$pekerjaan = Penyedia::with('pekerjaans')->where('id',$penyedia->id)->get()
return view('admin.showpekerjaan',['pekerjaan' => $pekerjaan]);
}
for view you can put id of penyedia like:
Beri Penilaian
