You can install the package via composer with following command:

composer require korridor/laravel-has-many-sync

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

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

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

You can access the sync method like this:

$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.

$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.

$customer->contacts()->sync([
    [
        'id' => 7, // ID that belongs to a different customer than `$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.

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');
    }
}
