Laravel Smart

Laravel Smart Demo

Do not use this package in production!

  1. This is a proof of concept. (update: this package is used successfully in an app that has 25 models)
  2. The code is not unit tested. (update: thanks to @robsontenorio we have basic unit testing)
  3. The API is not stable.

I release this alpha version to get feedback on the API and to make sure I'm not missing important use cases.

Also, I cannot build this alone! I'm more than happy to receive help from the community. Don't be shy!

  • join the discussions (even if it's not your issue)
  • improve the documentation (if you found something hard to understand, raise an issue, send a pull-request, etc)
  • contribute with code (I will guide you as much as needed)


If you define the fields in the model, you can get:

  • automatic migrations
  • automatic validation on save()
  • grouped field definition (name, schema type, casting, fillable/guarded, validation rules, schema modifiers, schema indexes)

namespace App;

use Deiucanta\Smart\Field;
use Deiucanta\Smart\Model;

class Product extends Model
    public function fields()
        return [
            Field::make('sku')->string()->fillable()->required()->unique()->label("Sku Number"),
            Field::make('price')->decimal(6, 2)->fillable()->required()->min(0),


To install the package, just run:

composer require deiucanta/smart


Create a Smart model:

php artisan smart:model Product

Include the model in the configuration file (config/smart.php):

Note: this is now done automatically when you create the model.


return [
    'models' => [

Create a Smart migration:

php artisan smart:migration

You should be able to see a new migration in your migration directory. To apply the migration, you just run php artisan migrate as usual.

You will find a new file called smart.json in the database directory of your app. That is where the package stores the current state of the database/models. If you delete that file and run php artisan smart:migration, it will create a new migration as if the schema was empty.


These are the primitives with which you should be able to create any kind of field. However, there are some smarter methods which you can use.

Base methods

Method Description
type($type, $args) Set the type to be used in migrations
cast($cast) Set the cast type
rule($rule) Add a validation rule (Laravel format)
guarded() Make the field guarded
fillable() Make the field fillable
index() Add a simple index on this field in migrations
unique($where_closure = null) Add a unique index in migrations and a smart validation rule that ignores the current model id
primary() Add a primary key on this field in migrations
default($default) Set the default value in migrations and set the model attribute when you instantiate the model
nullable() Make the field nullable in migrations and also add the nullable validation rule
unsigned() Add the unsigned modifier in migrations
label($value) Set the field label for validation errors bag
