Laravel LTI Provider

This packages provides a bridge between the Celtic LTI Package and Laravel models, by implementing a DataConnector for the Celtic LTI Package.

Install

Via Composer

$ composer require swisnl/laravel-lti-provider

Then run command to copy the required files (including the migrations) into your project.

php artisan lti-provider:install

If you have Laravel package auto discovery disabled, add the service provider to your config/app.php file:

'providers' => [
    // ...
    Swis\Laravel\Lti\Providers\LtiProviderServiceProvider::class,
];

Finally run the migrations.

php artisan migrate

Cron jobs

The package comes with a command to clean up expired LTI nonces. To run this command, add the following to your app/Console/Kernel.php file:

    protected function schedule(Schedule $schedule)
    {
        // ...
        $schedule->command('lti-provider:delete-expired-nonces')->daily();
    }

Usage

Define a model that you use as an LTI environment. This model should implement the Swis\Laravel\Lti\Contracts\LtiEnvironment. The packages scopes all other models to the current LTI environment.

Using this this environment, you can create a new ModelDataConnector instance. This instance can be used like the DataConnector from the Celtic LTI Package.

    $environment = MyLtiEnvironment::find($id);
    $dataConnector = new ModelDataConnector($environment);

Customization

This package allows overriding most of the models. We use this to override some models to use UUIDs instead of numeric ids, and to add some extra functionality (examples of this extra functionality: adding logging to UserResult; and using the same Client model for both LTI and Laravel Passport).

To override a model (except the client), create a new class that extends the original model and register the new model in the config/lti-provider.php file. For example, to override the UserResult model, create a new class that extends the Swis\Laravel\Lti\Models\UserResult class and change the following to your config/lti-provider.php file:

        'models' => [
            'user-result' => 'REFERENCE TO YOUR NEW CLASS',
        ],

Clients are a bit different, because you don't need to extend from an existing class. To override the client, create a new class that implements the Swis\Laravel\Lti\Contracts\Client interface and register the new model in the config/lti-provider.php file.

For inspiration on how to implement your own client, take a look at the Swis\Laravel\Lti\Models\SimpleClient class (a very basic implementation) or the \Workbench\App\OverrideModels\Client class (this is a more complex example used in the tests to check if it is possible to override the default implementation and if the package can handle clients with UUIDs instead of numeric ids).
