A Laravel collection extension to store enums with a useful eloquent field cast and a helper trait.
Take your interaction with enums to the next level.
Compatible with PureEnum, BackedEnum and datomatic/laravel-enum-helper package.

Installation

You can install the package via composer:

The main parts of the package are:

• enumCollection
• Eloquent model casting
• HasEnumCollections trait

EnumCollection

EnumCollection is an extension of base Laravel collection that expand his functionalities to add the compatibility with:

• enum object instance
• enum case name string
• enum case value (only for BackedEnum)
• enum case (string) value (only for IntBackedEnum)

Creating an EnumCollection

You can make enum collection in 4 ways:

from method throw an ValueError Exception if an element in $data is wrong, instead tryFrom skips bad data without raise exceptions.
$data can be a single element or a collection, array,... of elements.

If $data contains only Enum elements you can also omit the EnumClass (the collection take the EnumClass of the first element).

Contains method

toValues method

toValues method serialize the collection content, if the element is a PureEnum will be pass the name of the case, otherwise the value.

Casting

You can cast a field to be an EnumCollection. To use this casting option, you need to set the Eloquent Model properly.

1. Database Migration

2. Model set up

To set up your model you must:

• add a custom cast AsLaravelEnumCollection::class with the enumClass as attribute
• add an optional HasEnumCollections trait to make query on enum collections fields

You can also cast more than one field if you need.

Set the enum collection field

You can set enum collection field passing a single element, a collection or an array of elements. After the field will become an EnumCollection.

Database saved data

A serialization of enumCollection is saved in the database, if the element is a PureEnum will be saved the name of the case, otherwise the value.

EnumCollection

Thanks to casting you can interact with field_name like a normal EnumCollection with all functionalities showed before.

HasEnumCollections trait

If you include also the HasEnumCollections into the model, you can query the models with the new where functions whereContains, orWhereContains, whereDoesntContain and orWhereDoesntContain.
