In our last tutorial, we learnt how to create the ListTicketsByAuthUser Feature, the feature that is responsible for listing all the tickets by the authenticated user. To achieve the previous task, we built the following;

1. We needed the category repository and lastly
2. We needed the ListAllCategoryJob.
   Here we are again, another feature, ListTicketByIdFeature
   you can take a look at the course curriculum to catch up with us.

Requirements

the following are the requirements for this tutorial

• Download php 7.2.1
• Download Composer.exe
• Download xampp or wamp for windows.

Difficulty level

This tutorial is rated as intermediate.

What's our task for today?

Our tasks today is to build the ListTicketByIdFeature, which is responsible for getting a specific users ticket using the id in the model to fetch the ticket

to achieve this we are going to build the LIstTicketByIdJob, as the name implies, the jobs list the ticket using the id.
We are going to learn how to pass the id from a model to a feature.

Lets begin

We going to start by initiating the route
Ok route where are you, yeep it in web.php of the web service. Head over there.
add the code below

Route::get('tickets/{ticket_id}', 'TicketController@show');

This time around, we are passing the ticket_id as a variable to the TicketController's show method. Our route url would look like localhost:8000/tickets/1

Passing the ticket_id to the controller

Open the ticket controller and add the code below in the show method
the remember to use the ListTicketByIdFeature at the top
use App\Services\Web\Features\ListTicketByIdFeature;

 */
    public function show($ticket_id)
    {
        return $this->serve(ListTicketByIdFeature::class,[

            'id' => $ticket_id,
        ]);
    }

Let's explain this piece of code.
We are setting the id in the ListTicketFeature to the ticket_id of the route from the ticket model in the constructor method of the ListTicketFeature.

Feature time!!!! (ListTicketByIdFeature)

We would start by hitting the command line to generate our feature

Enter lucid make:feature ListTicketById web
Boom!!!!!!!!! generated.

Open the generated feature
and add the code.

<?php
namespace App\Services\Web\Features;

use Lucid\Foundation\Feature;
use Illuminate\Http\Request;
use App\Domains\Tickets\Jobs\ListTicketByIdJob;

class ListTicketByIdFeature extends Feature
{
    public function __construct($id)
    {
        $this->id = $id;
    }

    public function handle(Request $request)
    {
        $ticket = $this->run(ListTicketByIdJob::class,[

            'id' => $this->id,
            'field' => 'ticket_id'
        ]);

        $category = $ticket->category;

        $comments = $ticket->comments;

    

    return view('tickets.show', compact('ticket', 'category', 'comments'));
    }
}

Now, lets talk about this section
Notice the construct accepts the id we passed from the controller.
In this section below, we are running a ListTicketByJob and we don't have this particular job

$ticket = $this->run(ListTicketByIdJob::class,[

            'id' => $this->id,
            'field' => 'ticket_id'
        ]);

So we are going create the job

lucid make:job ListTicketByIdJob

find the generated job at Domains/Tickets/Jobs/ListTicketByIdJob.php

paste below snippet

<?php
namespace App\Domains\Tickets\Jobs;

use Lucid\Foundation\Job;
use App\Data\Repositories\TicketRepository;

class ListTicketByIdJob extends Job
{
   /**
    * Create a new job instance.
    *
    * @return void
    */
   protected $id;
   protected $field;


   public function __construct($id, $field)
   {
       $this->id = $id;
       $this->field = $field;
    
   }

   /**
    * Execute the job.
    *
    * @return void
    */
   public function handle(TicketRepository $repo)
   {
       return $repo->model->where($this->field, $this->id)->firstOrFail();
   }

}   

This jobs go to the repository and get the tickets with the id , the job, uses a the where method of the repository class, which accepts two variables, a ticket itselt, and the ID we are looking for.

Back to the Feature (ListTicketByIdFeature)

We ran the ListTicketJob, next we save the category of a particular ticket to the variable $category through the relationship between tickets and category.

lastly the both data "$ticket and $category" are sent to the tickets/show.blade.php view

@extends('layouts.app')

@section('title', $ticket->title)

@section('content')
    <div class="row">
        <div class="col-md-10 col-md-offset-1">
            <div class="panel panel-default">
                <div class="panel-heading">
                    #{{ $ticket->ticket_id }} - {{ $ticket->title }}
                </div>

                <div class="panel-body">
                    @include('includes.flash')

                    <div class="ticket-info">
                        <p>{{ $ticket->message }}</p>
                        <p>Categry: {{ $category->name }}</p>
                        <p>
                        @if ($ticket->status === 'Open')
                            Status: <span class="label label-success">{{ $ticket->status }}</span>
                        @else
                            Status: <span class="label label-danger">{{ $ticket->status }}</span>
                        @endif
                        </p>
                        <p>Created on: {{ $ticket->created_at->diffForHumans() }}</p>
                    </div>

                    <hr>

                        <div class="comments">
                            @foreach ($comments as $comment)
                                <div class="panel panel-@if($ticket->user->id === $comment->user_id) {{"default"}}@else{{"success"}}@endif">

                                        <span class="pull-right">{{ $comment->created_at->format('Y-m-d') }}</span>
                                    </div>

                            @endforeach
                        </div>

                    <div class="comment-form">
                        <form action="{{ url('comment') }}" method="POST" class="form">

                            <input type="hidden" name="ticket_id" value="{{ $ticket->id }}">

                            <div class="form-group{{ $errors->has('comment') ? ' has-error' : '' }}">
                                <textarea rows="10" id="comment" class="form-control" name="comment"></textarea>
