LARAVEL API

Create Laravel application

laravel new api-advertisement

OR

composer create-project laravel/laravel api-advertisement

Update the create_users_table migration

Add $table->boolean('is_admin')->default(false); to the code

The database/migrations/0001_01_01_000000_create_users_table.php file content will become

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     */
    public function up(): void
    {
        Schema::create('users', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('email')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->boolean('is_admin')->default(false);
            $table->rememberToken();
            $table->timestamps();
        });

        Schema::create('password_reset_tokens', function (Blueprint $table) {
            $table->string('email')->primary();
            $table->string('token');
            $table->timestamp('created_at')->nullable();
        });

        Schema::create('sessions', function (Blueprint $table) {
            $table->string('id')->primary();
            $table->foreignId('user_id')->nullable()->index();
            $table->string('ip_address', 45)->nullable();
            $table->text('user_agent')->nullable();
            $table->longText('payload');
            $table->integer('last_activity')->index();
        });
    }

    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        Schema::dropIfExists('users');
        Schema::dropIfExists('password_reset_tokens');
        Schema::dropIfExists('sessions');
    }
};

Create Two users

In the database/seeders/DatabaseSeeder.php add the following code

        User::factory()->create([
            'name' => 'Super User',
            'email' => '[email protected]',
            'password' => bcrypt('password'),
            'is_admin' => true,
        ]);
        User::factory()->create([
            'name' => 'Another User',
            'email' => '[email protected]',
            'password' => bcrypt('password'),
        ]);

The entire code will become

database/seeders/DatabaseSeeder.php

<?php

namespace Database\Seeders;

use App\Models\Advertisement;
use App\Models\User;
// use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     */
    public function run(): void
    {
        // User::factory(10)->create();

        User::factory()->create([
            'name' => 'Super User',
            'email' => '[email protected]',
            'password' => bcrypt('password'),
            'is_admin' => true,
        ]);
        User::factory()->create([
            'name' => 'Another User',
            'email' => '[email protected]',
            'password' => bcrypt('password'),
        ]);

    }
}

Make Advertisement Model, Migration for the model and Controller with resource methods for the model

Terminal
```
php artisan make:model Advertisement -mcr
```

Update the migration file to define the structure of our advertisement

Add the following code in

database/migrations/timestamp_create_advertisements_table.php

$table->string('title');
$table->string('content');
$table->string('image_path')->nullable();
$table->boolean('is_approved')->default(false);
$table->foreignIdFor(User::class);

You need to add
```
use App\Models\User;
```
On the top of the page

The full code will looks like

database/migrations/timestamp_create_advertisements_table.php

<?php

use App\Models\User;
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     */
    public function up(): void
    {
        Schema::create('advertisements', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->string('content');
            $table->string('image_path')->nullable();
            $table->boolean('is_approved')->default(false);
            $table->foreignIdFor(User::class)->nullable();
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        Schema::dropIfExists('advertisements');
    }
};

Run the migration
Terminal
```
php artisan migrate
```
Note:

user_id column will be created by $table->foreignIdFor(User::class);
Add another seeder to create a dummy advertisement data
database/seeders/DatabaseSeeder.php

Advertisement::create([
    'title' => 'Virthli',
    'content' => 'MZU will be organizing Virthli, everyone is invited to come. Ticket will be available by the main gate',
    'is_approved' => true,
    'user_id' => 1
]);

Advertisement::create([
    'title' => 'Software Engineer Job Vacant',
    'content' => 'A full-stack software engineer job vacnt in Microsoft mizoram branch',
    'is_approved' => true,
    'user_id' => 2
]);

Advertisement::create([
    'title' => 'Programming Course',
    'content' => 'A full-stack programming 6 months course is open contact 123456789 for detail',
    'is_approved' => false,
    'user_id' => 2
]);

Wih the existing one. The entire DatabaseSeeder.php file will look like

<?php

namespace Database\Seeders;

use App\Models\Advertisement;
use App\Models\User;
// use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     */
    public function run(): void
    {
        // User::factory(10)->create();

        User::factory()->create([
            'name' => 'Super User',
            'email' => '[email protected]',
            'password' => bcrypt('password'),
            'is_admin' => true,
        ]);
        User::factory()->create([
            'name' => 'Another User',
            'email' => '[email protected]',
            'password' => bcrypt('password'),
        ]);

        Advertisement::create([
            'title' => 'Virthli',
            'content' => 'MZU will be organizing Virthli, everyone is invited to come. Ticket will be available by the main gate',
            'is_approved' => true,
            'user_id' => 1
        ]);

        Advertisement::create([
            'title' => 'Software Engineer Job Vacant',
            'content' => 'A full-stack software engineer job vacnt in Microsoft mizoram branch',
            'is_approved' => true,
            'user_id' => 2
        ]);

        Advertisement::create([
            'title' => 'Programming Course',
            'content' => 'A full-stack programming 6 months course is open contact 123456789 for detail',
            'is_approved' => false,
            'user_id' => 2
        ]);
    }
}

Run the seeder
Terminal

```plaintext
php artisan db:seed
```

This will create admin user, another user and the three advertisement entries.

Add a method to fetch the advertisements

In `app/Http/Controllers/AdvertisementController.php` update the index() method

```php
public function index()
{
    return Advertisement::all();
}
```

Generate api route
Terminal

```plaintext
php artisan install:api
```

Run the migration.

Create a route to fetch the advertisements
in the routes/api.php file, Add

```php
Route::apiResource('/', function () {
    return view('welcome');
});
```

This will create all the required endpoints to utilize/access the api resource methods.

Then, you will be able to access the dummy data from the web page

Click [HERE](http://127.0.0.1:8000/api/advertisements) to view the data returned by the api

Add a method to store the advertisements

In app/Http/Controllers/AdvertisementController.php update the store() method

public function store(Request $request)
{
    $validated = $request->validate([
        'title' => 'required',
        'content' => 'required',
        'is_approved' => 'nullable',
    ]);

    $validated['user_id'] = request()?->user()?->id ?? null;

    Advertisement::create($validated);
    return $this->index();
}

Note:

the Route::apiResource('advertisements') method called in `routes/api.php` already defined the route for this store and all other required methods for api Advertisement routes.

Add a method to store the advertisements

In app/Http/Controllers/AdvertisementController.php update the update() method

public function update(Request $request, Advertisement $advertisement)
{
    $validated = $request->validate([
        'title' => 'required',
        'content' => 'required',
        'is_approved' => 'nullable',
    ]);

    $advertisement->update($validated);
    return $this->index();
}

In app/Http/Controllers/AdvertisementController.php update the destroy() method

public function update(Advertisement $advertisement)
{
    $advertisement->delete();
    return $this->index();
}

Now the entire AdvertisementController.php file will have the following content

<?php

namespace App\Http\Controllers;

use App\Models\Advertisement;
use Illuminate\Http\Request;

class AdvertisementController extends Controller
{
    /**
     * Display a listing of the resource.
     */
    public function index()
    {
        return Advertisement::all();
    }

    /**
     * Show the form for creating a new resource.
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     */
    public function store(Request $request)
    {
        $validated = $request->validate([
            'title' => 'required',
            'content' => 'required',
            'is_approved' => 'nullable',
        ]);

        $validated['user_id'] = request()?->user()->id ?? null;

        Advertisement::create($validated);
        return $this->index();
    }

    /**
     * Display the specified resource.
     */
    public function show(Advertisement $advertisement)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     */
    public function edit(Advertisement $advertisement)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     */
    public function update(Request $request, Advertisement $advertisement)
    {
        $validated = $request->validate([
            'title' => 'required',
            'content' => 'required',
            'is_approved' => 'nullable',
        ]);

        $advertisement->update($validated);
        return $this->index();
    }

    /**
     * Remove the specified resource from storage.
     */
    public function destroy(Advertisement $advertisement)
    {
        $advertisement->delete();
        return $this->index();
    }
}
