this is the car controller

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Brand;
use App\Models\Car;

class CarController extends Controller
{
    public function index(){
        return view('/dashboard/index');
    }
    public function create(){
        $brand = Brand::all();
        return view('dashboard.create')->with('brand', $brand);
    }
    public function store(Request $request){
        $car = new Car();

        $car->brand_id = request('brand_id');
        $car->model = request('model');
        $car->kilometrage = request('kilometrage');
        $car->engine = request('engine');
        $car->description = request('description');
        $car->price = request('price');
        $car->transmission = request('transmission');
        if($request->hasfile('image')){
            $file = $request->file('image');
            $extention = $file->getClientOriginalExtension();
            $filename = time().'.'.$extention;
            $file->move('img/', $filename);
            $car->image = $filename;
        }

        $car->save();

        return redirect('/dashboard/create');
    }

    public function show(){

       // $brand = Car::with('brand');
        $cars = Car::all();
        return view('car.car_listing', ['cars' => $cars]);    
    }  
}

Routes

<?php
use App\Http\Controllers\UserController;
use Illuminate\Support\Facades\Route;

Route::get('/', function () {
    return view('welcome');
});

//
/*Route::get('/dashboard', function () {
    return view('layouts/dashboard');
})->middleware(['auth'])->name('dashboard');*/


Route::group( ['middleware' => ['auth', 'role:administrator']], function(){
    Route::get('/dashboard', 'App\Http\Controllers\CarController@index');
    Route::get('/dashboard/create', 'App\Http\Controllers\CarController@create');
    Route::post('/dashboard', 'App\Http\Controllers\CarController@store');
    Route::get('/dashboard/create_brand', 'App\Http\Controllers\BrandController@create');
    Route::post('/dashboard/create_brand','App\Http\Controllers\BrandController@store');
    Route::get('/dashboard/create_brand', 'App\Http\Controllers\BrandController@show');

});

Route::group( ['middleware' => ['auth', 'role:user']], function(){
    Route::get('/profile', function(){
        return view('profile/profile');
    });    
});

Route::get('/car_listing', 'App\Http\Controllers\CarController@show');

Route::resource('user', UserController::class)->shallow();
//Route::get('user', [UserController::class, 'index'])->name('user.index');

require __DIR__.'/auth.php';

this is where i want to display the value of the foreign key and it shows nothing

@foreach($cars as $car)
    <div class="col-md-6">
        <div class="single-offers">
            
            <div class="offer-image">
                <a href="car-listing.html#">
                    <img src="{{ asset('img/'.$car->image) }}" alt="offer 1" />
                </a>
            </div>
            
            <div hljs-string">">
                    <div>
                        <a href="car_listing">
                            <h3 value="{{$car->brand_id}}">{{$car->brand_name}}</h3>
                        </a>
                    </div>
               
                
                <h4>${{$car->price}}<span>/ Day</span></h4>
                <ul>
                    <li><i hljs-string">"></i>Model:{{$car->model}}</li>
                    <li><i hljs-string">"></i>{{$car->transmission}}</li>
                    <li><i hljs-string">"></i>{{$car->kilometrage}}kmpl</li>
                </ul>
                <div hljs-string">">
                    <a href="car-listing.html#" >Rent Car</a>
                    <a href="car-listing.html#" class="offer-btn-2">Details</a>
                </div>
                
            </div>
            
        </div>
    </div>
    
@endforeach

when i do this it shows me the id im new to laravel and i don't know how to make this work, can you help me with showing the value of the foreign key instead of the foreignkey itself thank you

<h3 value="">{{$car->brand_id}}</h3>

CodePudding user response：

Have you created a relation in Cars models?

example in Cars Model

public function brand() { 
 return $this->belongsTo(Brands::class,'brand_id'); 
}

at view page

$car->brand->brand_name

CodePudding user response：

You can create function in car model like this

public function brandDetails(){
    return $this->hasOne('Brand model path', 'brand_table_key','car_table_foreignkey');
}

And this function use in with method

public function show(){
    $cars = Car::with(['brandDetails']);
    return view('car.car_listing',compact('cars'));  
}
