## Installation

You can install the package via composer with following command:

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

If you want to use this package with older Laravel/PHP version please install the 1.* version.

```bash
composer require korridor/laravel-has-many-merged "^1"
```

**Warning: The 1.\* versions use a different namespace!**

### Requirements

This package is tested for the following Laravel and PHP versions:

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

## Usage

### Setup HasMany Relation

```php
class Customer extends Model
{
/**
* @return HasMany
*/
public function contacts(): HasMany
{
return $this->hasMany(CustomerContact::class);
}
}
```

You can access the sync method like this:

```php
$customer->contacts()->sync([
[
'id' => 1,
'name' => 'Alfa',
'phone_number' => '123',
],
[
'id' => null,
'name' => 'Adhitya',
'phone_number' => '234,
]
]);
```

The sync method accepts an array of data to place on the intermediate table. Any data that are not in the given array will be removed from the intermediate table. So, after this operation is complete, only the data in the given array will exist in the intermediate table.

#### Syncing without deleting

If you do not want to delete existing data, you may pass false value to the second parameter in the sync method.

```php
$customer->contacts()->sync([
[
'id' => 1,
'name' => 'Alfa',
'phone_number' => '123',
],
[
'id' => null,
'name' => 'Adhitya',
'phone_number' => '234,
]
], false);
```

#### Behaviour for IDs that are not part of the hasMany relation

If an ID in the related data does not exist or is not in the scope of the `hasMany` relation, the `sync` function will throw a `ModelNotFoundException`.
It is possible to modify this behavior with the `$throwOnIdNotInScope` attribute. Per default, this is set to `true`. If set to false, the `sync` function will ignore the Ids instead of throwing an exception.

```php
$customer->contacts()->sync([
[
'id' => 7, // ID that belongs to a different customer than `$customer`
'name' => 'Peter',
'phone_number' => '321',
],
[
'id' => 1000, // ID that does not exist
'name' => 'Alfa',
'phone_number' => '123',
],
[
'id' => null,
'name' => 'Adhitya',
'phone_number' => '234,
]
], throwOnIdNotInScope: false);
```

#### Example usage in the controller.

```php
class CustomersController extends Controller
{
/**
* Update the specified resource in storage.
*
* @param CustomerRequest $request
* @param Customer $customer
* @return \Illuminate\Http\Response
*/
public function update(CustomerRequest $request, Customer $customer)
{
DB::transaction(function () use ($customer, $request) {
$customer->update($request->all());
$customer->contacts()->sync($request->get('contacts', []));
});

return redirect()->route('customers.index');
}
}
```
