Usage

getModelRelations()

The getModelRelations() method returns a Collection of all relations of a Model, with additional information like the name of the relation, relation type, related class and an empty base instance of the given Model from Eloquent.

ModelReflector::getModelRelations(User::class);

// Returns 

Illuminate\Support\Collection {#5236
    all: [
        "Images" => [
             "relation" => "Images",
             "returnType" => "Illuminate\Database\Eloquent\Relations\HasMany",
             "relatedClass" => "App\Models\Image",
             "relatedModel" => App\Models\Image {#5237},
             "relatedTable" => "images",
             "foreignKeyName" => "id",
             "qualifiedForeignKeyName" => "images.id",
             "isRelationParent" => false,
         ]
    ]
}

getRelationByTarget()

The getRelationByTarget() method returns the name of a Relation between the Model and the Target.

$user = new User;
$image = new Image;

ModelReflector::getRelationByTarget($user, $image);

// Returns 

'Images'

hasRelation()

The hasRelation() method returns true if a Model has a specific relation.

ModelReflector::hasRelation(User::class, 'Images');

// Returns

true

getMethodReturnType()

The getMethodReturnType() method returns the type of a specific method on a given Object or Model class. It returns false when the Method does not exist. It returns null if no return type is type hinted.

$user = new User;

ModelReflector::getMethodReturnType($user, 'Images');

// Returns 

'Illuminate\Database\Eloquent\Relations\HasMany'

getModelInstance()

The getModelInstance() method checks if the given model is an instance of a Model or the fully qualified class name of a Model, and returns the model or the empty Eloquent base Model of the given class.

ModelReflector::getModelInstance('App\Models\User');

// Returns an empty object of the User class

getModelClass()

The getModelClass() method checks if the given model is an instance of a Model or the fully qualified class name of a Model, and returns the class of the given Model.

$user = new User;

ModelReflector::getModelClass($user);

// Returns

'App\Models\User'

resolveModelObject()

The resolveModelObject() method resolves a Model based on a given Model or a Class and the according identifier. If no identifier is given, it returns an empty Builder-Model. If the desired Model can not be found, it will return null.

ModelReflector::resolveModelObject(Image::class, 10);

// Returns the Image object with the key 10

resolveRelatedModel()

The resolveRelatedModel() method resolves a related Model by the source and the given Relation. Currently, we only support HasOne or BelongsTo-Relations, as those only return a single Model or null.

ModelReflector::resolveRelatedModel($image, 'User');

// Returns the User object that the Image object belongs to

resolveRelatedModelByTarget()

The resolveRelatedModelByTarget() method resolves a related Model by the source and the given TargetModel.

ModelReflector::resolveRelatedModelByTarget($image, User::class);

// Returns the User object that the Image object belongs to 

getModelShortName()

The getModelShortName() method returns the Short-Name of a Model.

$image = new Image;

ModelReflector::getModelShortName($image);

// Returns

'Image'

getAllModels()

The getAllModels() method returns a Collection of all available Models via the Filesystem.

ModelReflector::getAllModels();

// Returns 

Illuminate\Support\Collection {#384
    all: [
    "App\Models\User\Image",
    "App\Models\User",
    ],
}

getAllInstantiatableModels()

The getAllInstantiatableModels() method returns a Collection of all instantiatable Model-Classes, which are not Abstract. It returns the full qualified Class-Name as key with the according Short-Name as value.

ModelReflector::getAllInstantiatableModels();

// Returns all kinds of empty objects

Illuminate\Support\Collection {#4929
    all: [
    "App\Models\User\Image" => App\Models\User\Image {#4928},
    "App\Models\User" => App\Models\User {#4921},
    ],
}

getInstantiatableModelStructureInformation()

The getInstantiatableModelStructureInformation() method returns a Collection of structure information for all instantiatable Model-Classes, which include the fully qualified name of the parent class and the child classes.

ModelReflector::getInstantiatableModelStructureInformation();

// Returns 

Illuminate\Support\Collection {#1469
    all: [
        "App\Models\User" => Illuminate\Support\Collection {#1482
            all: [
                "parentClass" => null,
                "childClasses" => [
                 "App\Models\User\Image",
                ],
            ],
        },
        "App\Models\User\Image" => Illuminate\Support\Collection {#1483
            all: [
                "parentClass" => "App\Models\User",
                "childClasses" => [],
            ],
        }
    ],
}

getClassFromMorphMap()

The getClassFromMorphMap() method returns the class name from the Morph-Map alias (reverse lookup), the alias or null (if strict is true).

ModelReflector::getClassFromMorphMap('user');

// Returns

'App\Models\User'

getMorphAliasForClass()

The getMorphAliasForClass() method returns the morph alias for the specified Model.

ModelReflector::getMorphAliasForClass('App\Models\User');

// Returns

'user'

modelHasTraits()

The modelHasTraits() method validates if a Model implements one or more specific Traits.

ModelReflector::modelHasTraits(User::class, 'Illuminate\Database\Eloquent\Concerns\HasAttributes');
