Creating a CRUD Interface

Creating a CRUD interface with Backpack is straightforward. Here’s how you can create a CRUD for a Post

model:

Generate the Model: First, create your model and migration:

php artisan make:model Post -m

1

php artisan make:model Post -m

Define the Migration: In the migration file, define the columns you want for your posts table:

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

class CreatePostsTable extends Migration
{
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->text('content');
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('posts');
    }
}

use Illuminate\Database\Migrations\Migration;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Support\Facades\Schema;

class CreatePostsTable extends Migration

{

public function up()

{

Schema::create('posts', function (Blueprint $table) {

$table->id();

$table->string('title');

$table->text('content');

$table->timestamps();

});

}

public function down()

{

Schema::dropIfExists('posts');

}

Run the Migration: Run the migration to create the posts table:

php artisan migrate

1

php artisan migrate
Create the CRUD Controller: Generate a CRUD controller for the Post model:

php artisan backpack:crud Post

1

php artisan backpack:crud Post

Define the CRUD Fields: Open the generated PostCrudController.php file and define the fields for your CRUD interface:

namespace App\Http\Controllers\Admin;

use App\Http\Requests\PostRequest;
use App\Models\Post;
use Backpack\CRUD\app\Http\Controllers\CrudController;

class PostCrudController extends CrudController
{
    public function setup()
    {
        $this->crud->setModel(Post::class);
        $this->crud->setRoute(config('backpack.base.route_prefix') . '/post');
        $this->crud->setEntityNameStrings('post', 'posts');

        $this->crud->addField([
            'name' => 'title',
            'type' => 'text',
            'label' => 'Title',
        ]);

        $this->crud->addField([
            'name' => 'content',
            'type' => 'ckeditor',
            'label' => 'Content',
        ]);
    }

    public function store(PostRequest $request)
    {
        return parent::storeCrud($request);
    }

    public function update(PostRequest $request)
    {
        return parent::updateCrud($request);
    }
}

namespace App\Http\Controllers\Admin;

use App\Http\Requests\PostRequest;

use App\Models\Post;

use Backpack\CRUD\app\Http\Controllers\CrudController;

class PostCrudController extends CrudController

{

public function setup()

{

$this->crud->setModel(Post::class);

$this->crud->setRoute(config('backpack.base.route_prefix') . '/post');

$this->crud->setEntityNameStrings('post', 'posts');

$this->crud->addField([

'name' => 'title',

'type' => 'text',

'label' => 'Title',

]);

$this->crud->addField([

'name' => 'content',

'type' => 'ckeditor',

'label' => 'Content',

]);

}

public function store(PostRequest $request)

{

return parent::storeCrud($request);

}

public function update(PostRequest $request)

{

return parent::updateCrud($request);

}

Set Up Routes: Backpack automatically sets up the routes for the CRUD operations in the routes/backpack/custom.php file.

Accessing the Admin Panel

After completing the setup, you can access the admin panel by navigating to the URL:

http://your-app-url/admin
