Get specific value Laravel - php

Question

I have car table with status field and there's "available", and "breakdown".
I also got fleet CRUD, once I add fleet I want to show car with only "available" status. what should I add ?
here's my fleet controller code :
<?php
namespace App\Http\Controllers;
use App\Http\Requests;
use App\Models\Fleet;
use App\Models\Car;
use App\Models\Attendance;
use App\Helpers\Enums\FleetStatus;
use App\Models\AttendanceDetail;
use Illuminate\Http\Request;
use Yajra\Datatables\Datatables;
use App\Http\Controllers\Base\MasterController;
use Route;
use Illuminate\View\View;
class FleetController extends MasterController
{
protected $detailView = 'fleet.show';
protected $indexView = 'fleet.index';
protected $createView = 'fleet.form';
protected $editView = 'fleet.form';
protected $routeBindModel = 'fleet'; //Route Model Binding name in RouteServiceProvider
protected $redirectPageWhenFormSuccess = 'fleet.index'; //Route Name
protected $title = 'Fleet';
public function save(Request $request, $obj = null) {
if (!$obj) {
$obj = new Fleet;
}
return $this->saveHandler($request, $obj);
}
//Must have this method if need datatable;
public function datatableBuilder($obj = null) {
return Fleet::query();
}
public function makeDatatable($obj) {
return Datatables::of($obj)
->addColumn('action', function ($model) {
return $this->makeActionButtonsForDatatable($model);
})
->editColumn('status', function($model){
return FleetStatus::getString($model->status);
})
->make(true);
}
public function render(View $view, $route = null, $obj = null, $method = 'POST') {
$statusList = FleetStatus::getArray();
$carStatusList = Car::pluck('plate_no', 'id');
$attendanceList = Attendance::pluck('driver_id', 'id');
$workingHourList = Attendance::pluck('working_hours', 'id');
$view->with(compact('statusList', 'carStatusList', 'attendanceList', 'workingHourList'));
return parent::render($view, $route, $obj, $method);
}
}
here's my add form code :
<div class="col-xs-12 col-sm-12 col-md-12">
<div class="form-group">
<label>Car </label>
{!! Form::select('car_id', $carStatusList, null, array('class' => 'form-control')) !!}
</div>
</div>

Answer 1

Have you try this:
$carStatusList = Car::where('status', 'available')->pluck('plate_no', 'id')

Answer 2

In your model add a scope
public function scopeAvailable($query){
return $query->where('status', '=', 'available');
}
And then wherever you need to use it:
Car::available()->get()
or
Car::available()->pluck('plate_no' , 'id');
More info here: https://laravel.com/docs/5.3/eloquent#query-scopes

Answer 3

If I understand your question correctly, this will create a list of available cars:
Car::where('status','available')->pluck('plate_no', 'id');
