After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Laravel Castable Data Transfer Object

Latest Version on Packagist GitHub Tests Action Status GitHub Code Style Action Status Total Downloads

Laravel is awesome. Spatie's data transfer object package for PHP is awesome. They're already good friends, but now they're taking their relationship to the next level 💕

Have you ever wanted to cast your JSON columns to a value object?

This package gives you an extended version of Spatie's DataTransferObject class, called CastableDataTransferObject.

Under the hood it implements Laravel's Castable interface with a Laravel custom cast that handles serializing between the DataTransferObject (or a compatible array) and your JSON database column.

For an in-depth explanation of what it's actually doing and the motivation behind it, check out the blog post that spawned it.

This package has also been featured on Laravel News!

Installation

You can install the package via composer:

Usage

1. Create your CastableDataTransferObject

Check out the readme for Spatie's data transfer object package to find out more about what their DataTransferObject class can do.

(Note: I like to put these in App\Values because I'm using them as a value object and not just a plain DTO. Feel free to put it anywhere you like!)

2. Configure your Eloquent attribute to cast to it:

Note that this should be a jsonb or json column in your database schema.

And that's it! You can now pass either an instance of your Address class, or even just an array with a compatible structure. It will automatically be cast between your class and JSON for storage and the data will be validated on the way in and out.

But the best part is that you can decorate your class with domain-specific methods to turn it into a powerful value object.

Using defaults for null database values

By default, if a database value is null, then the model attribute will also be null. However, sometimes you might want to instantiate the attribute with some default values.

To achieve this, you may provide an additional nullable Cast Parameter to ensure the caster gets instantiated.

This will ensure that the Settings caster is instantiated even when the settings column in the database is null.

You may then specify some default values in the cast which will be used instead.

Controlling serialization

You may provide the caster with flags to be used for serialization by adding the CastUsingJsonFlags attribute to your object:
