Laravel Model info is an excellent package by Spatie. This package offers a way to get information about the models in your Laravel app. Using this package you can determine which attributes and relations your model classes have.

Installation

You can install the package via composer:

composer require spatie/laravel-model-info

Usage

You can get information about a model by calling forModel:

use Spatie\ModelInfo\ModelInfo;

$modelInfo = ModelInfo::forModel(YourModel::class);

$modelInfo->fileName; // returns the filename that contains your model
$modelInfo->tableName; // returns the name of the table your models are stored in
$modelInfo->attributes; // returns a collection of `Attribute` objects
$modelInfo->relations; // returns a collection of `Relation` objects

Getting a specific attribute

use Spatie\ModelInfo\ModelInfo;

// returns an instance of `Spatie\ModelInfo\Attributes\Attribute`
ModelInfo::forModel(BlogPost::class)->attribute('name');

Getting a specific relation

You can get a specific relation using the relation method.

use Spatie\ModelInfo\ModelInfo;

// returns an instance of `Spatie\ModelInfo\Relations\Relation`
ModelInfo::forModel(BlogPost::class)->relation('user')

Discovering all models in your application

Using this method we’ll discover all methods in your project, no matter in which directory they are stored.

use Spatie\ModelInfo\ModelFinder;

// returns a `Illuminate\Support\Collection` containing
// all the class names of all your models.
$models = ModelFinder::all(); 

Getting information on all models in your application

The ModelInfo class can get information about all models in your application.

use Spatie\ModelInfo\ModelInfo;

ModelInfo::forAllModels(); // returns a collection of `ModelInfo` instances

Adding extra info on a model

To add extra info on a model, add a method extraModelInfo to your model. It can return anything you want: an string, an object, an array.

// in your model

public function extraModelInfo()
{
    return 'anything you want';
}

The returned value will be available on the extra property of a ModelInfo instance.

use Spatie\ModelInfo\ModelInfo;

$modelInfo = ModelInfo::forModel(YourModel::class);

$modelInfo->extra; // returns 'anything you want'
