Hot Swapping for Laravel Eloquent

Dhosa allows developers to implement hot-swapping capabilities on Eloquent models. This will helps package developer to create a base model and app developer can extends upon the base model while making sure that all the relationship uses the proper model.

Installation

To install through composer, run the following command from terminal:

composer require "laravie/dhosa"

Usages

Enable Hot-Swap

To enable hot-swap to any Eloquent all you need to do is use Laravie\Dhosa\Concerns\Swappable and implements the method.

<?php

namespace App\Models;

// ...
use Illuminate\Foundation\Auth\User as Authenticatable;
use Laravie\Dhosa\Concerns\Swappable;

class User extends Authenticatable
{
    use Swappable;
    
    /**
     * Get Hot-swappable alias name.
     *
     * @return string
     */
    public static function hsAliasName(): string
    {
        return 'User';
    }
}

Registering Hot-Swap

use Laravie\Dhosa\HotSwap;

HotSwap::register('Orchestra\Model\User');

Overriding Hot-Swap

In the App\Providers\AppServiceProvider we can now override the resolution of User to App\User by adding:

use Laravie\Dhosa\HotSwap;

HotSwap::override('User', 'App\User');

Defining relationship

You can define relationship by using the following code:

use Orchestra\Model\User;

/* ... */

public function user() 
{
    return $this->belongsTo(User::hsFinder());
}

Making queries

use Orchestra\Model\User;

$user = User::hs(); // return instance of App\User

$user = User::hs()->query(); // return a query builder for App\User

$user = User::hsOn('api'); // return a query builder for App\User using `api` db connection.

$user = User::hsOnWriteConnection(); // return a query builder for App\User using write PDO connection.

Helpers methods

use Orchestra\Model\Role;
use Orchestra\Model\User;

User::hsAliasName(); // return "User"

User::hsFinder(); // return "App\User"

Role::hsFinder(); // return "Orchestra\Model\Role"
