Laravel Nova: An Introduction

Laravel Nova is a powerful administration panel for Laravel applications. It provides a feature-rich interface that makes it easy to manage the admin side of your Laravel project. In this post, we will explore the steps to use Laravel Nova effectively for creating admin panels.

Step 1: Installing Laravel Nova

To start using Laravel Nova, you first need to install it. Simply run the following command in your Laravel project directory:

composer require laravel/nova

Once the installation is complete, you need to register Laravel Nova as a service provider in your config/app.php file:

'providers' => [
    // Other service providers...
    LaravelNovaNovaServiceProvider::class,
],

Step 2: Creating a Nova Resource

After installing and registering Laravel Nova, you can start creating admin resources. A Nova resource represents a logical entity that you want to manage through the administration panel. To create a Nova resource, run the following command:

php artisan nova:resource User

This command will generate a User resource class in the app/Nova directory. Inside this class, you can define the fields you want to display in the admin panel for the User entity.

Step 3: Defining Fields and Actions

Laravel Nova allows you to define various fields for each resource. You can use fields like Text, Number, Boolean, etc., to represent the attributes of your entity. Here’s an example of defining fields for the User resource:

public function fields(Request $request)
{
    return [
        ID::make()->sortable(),
        Text::make('Name'),
        Text::make('Email')->sortable(),
        Boolean::make('Active')->sortable(),
        // Other fields...
    ];
}

In addition to fields, you can also define actions that can be performed on your resources. Actions can be used to perform specific operations on one or more resources, such as deleting, updating, or exporting them.

Step 4: Registering Resources

To make your newly created admin resources accessible in the Laravel Nova panel, you need to register them with Nova. Open the app/Providers/NovaServiceProvider.php file and add the following code within the boot method:

public function boot()
{
    parent::boot();

    Nova::resources([
        User::class,
        // Other resources...
    ]);
}

After registering the resources, you can navigate to the Laravel Nova administration panel and start managing the entities represented by the resources.

Step 5: Customizing the Resources

Laravel Nova provides various customization options to tailor the admin panel according to your requirements. You can override default field behavior, define custom actions, create computed fields, and much more.

For instance, to customize the behavior of a Text field, you can define the resolve method in the field class. This method allows you to modify the value of the field before it gets displayed:

public function resolveAttribute($resource, $attribute)
{
    return strtoupper($resource->{$attribute});
}

This example will display the value of the Text field in uppercase in the administration panel.

Step 6: Authorization and Policies

Laravel Nova integrates seamlessly with Laravel’s authorization system. You can define policies for Nova resources, just like you would for any other Laravel functionality. This allows you to control access to admin panels based on user roles and permissions.

To define a policy for a Nova resource, use the policy property in the resource class:

public static $model = 'AppModelsUser';

public static $policy = 'AppPoliciesUserPolicy';

Make sure to create the corresponding policy class in the app/Policies directory to define the authorization rules for the specific resource.
