## Installation

You can install the package via composer with following command:

```bash
composer require korridor/laravel-has-many-merged
```

If you want to use this package with older Laravel/PHP version please install the 0.* version.

```bash
composer require korridor/laravel-has-many-merged "^0"
```

### Requirements

This package is tested for the following Laravel versions:

- 10.* (PHP 8.1, 8.2, 8.3)
- 11.* (PHP 8.2, 8.3)

## Usage examples

In the following example there are two models User and Message.
Each message has a sender and a receiver.
The User model has two hasMany relations - one for the sent messages and the other for the received ones.

With this plugin you can add a relation that contains sent and received messages of a user.

```php
use Korridor\LaravelHasManyMerged\HasManyMerged;
use Korridor\LaravelHasManyMerged\HasManyMergedRelation;

class User extends Model
{
use HasManyMergedRelation;

// ...

/**
* @return HasManyMerged
*/
public function messages(): HasManyMerged
{
return $this->hasManyMerged(Message::class, ['sender_user_id', 'receiver_user_id']);
}

/**
* @return HasMany
*/
public function sentMessages(): HasMany
{
return $this->hasMany(Message::class, 'sender_user_id');
}

/**
* @return HasMany
*/
public function receivedMessages(): HasMany
{
return $this->hasMany(Message::class, 'receiver_user_id');
}
}
```
