Using this package you can determine which attributes and relations your model classes have.

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

Here's how you can get information about the attributes:

$modelInfo->attributes->first()->name; // returns the name of the first attribute
$modelInfo->attributes->first()->type; // returns the type of the first attribute (string, integer, ...)

Here's how you can get information about the relations

// returns the name of the first relation, eg. `author`
$modelInfo->relations->first()->name;

// returns the type of the
// first relation, eg. `BelongsTo`
$modelInfo->relations->first()->type;

// returns the related model of the
// first relation, eg. `App\Models\User`
$modelInfo->relations->first()->related;

Additionally, the package can also discover all the models in your application.

use Spatie\ModelInfo\ModelFinder;

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

This package discovers relationships by their return type. Make sure that, in all your models each method that returns a relation has a return type.

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')

Attributes

A Spatie\ModelInfo\Attributes\Attribute object has these properties:

  • name
  • type
  • increments
  • nullable
  • default
  • unique
  • fillable
  • appended
  • cast
  • virtual

Relationships

A Spatie\ModelInfo\Relations\Relation object has these properties:

  • name
  • type
  • related

It also has a relatedModelInfo() method that gives a ModelInfo instance for the related model.

use Spatie\ModelInfo\ModelInfo;

ModelInfo::forModel(BlogPost::class)
   ->relation('user')
   ->relatedModelInfo() // returns the `ModelInfo` for the `User` model

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 model 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'
