Installation of Event Management App (REST API)

Create a laravel project

    composer create-project --prefer-dist laravel/laravel event-management

Modify .env file for database connection

    DB_DATABASE=laravel-10-event-management
    DB_USERNAME=[USERNAME]
    DB_PASSWORD=[PASSWORD]

Run migrate command to check if connection can be established and create the database

    php artisan migrate

Create Models with a migration file(-m)

    # create model with migration files
    php artisan make:model Event -m

source code

    # create model with migration files
    php artisan make:model Attendee -m

source code

Create API Controllers

    # create api controller for Attendee
    php artisan make:controller Api\AttendeeController --api

source code

    # create api controller for Event
    php artisan make:controller Api\EventController --api

source code

Creating routes on `routes/api.php`

    # use namespace on top
    use App\Http\Controllers\Api\AttendeeController;
    use App\Http\Controllers\Api\EventController;

    # add routes below
    Route::apiResource('events', EventController::class);
    Route::apiResource('events.attendees', AttendeeController::class)
        ->scoped(['attendee' => 'event']);

Define fields on migration and Relationships

    https://github.com/jeremyabulencia/MasterLaravel10-events-management-REST/commit/e0c7ce8ce2d8df604f2ba7c0fbb6225933eeed62

Run migration with seed to apply migrations to the Database

    php artisan migrate:refresh --seed

Defining Routes

routes.php

    Route::apiResource('events', EventController::class);
    Route::apiResource('events.attendees', AttendeeController::class)
        ->scoped(['attendee' => 'event']);

run the task

Encountered an error on mailpit

    Connection could not be established with host "mailpit:1025": stream_socket_client(): php_network_getaddresses: getaddrinfo for mailpit failed: No such host is known.

I ran this and discovered that it cached the unconfigured settings for mailpit

    $ grep -R mailpit * | egrep -v storage
    bootstrap/cache/config.php:        'host' => 'mailpit',
    vendor/laravel/sail/src/Console/Concerns/InteractsWithDockerComposeServices.php:        'mailpit',
    vendor/laravel/sail/src/Console/Concerns/InteractsWithDockerComposeServices.php:    protected $defaultServices = ['mysql', 'redis', 'selenium', 'mailpit'];
    vendor/laravel/sail/src/Console/Concerns/InteractsWithDockerComposeServices.php:        if (in_array('mailpit', $services)) {
    vendor/laravel/sail/src/Console/Concerns/InteractsWithDockerComposeServices.php:            $environment = preg_replace("/^MAIL_HOST=(.*)/m", "MAIL_HOST=mailpit", $environment);
    vendor/laravel/sail/stubs/mailpit.stub:mailpit:
    vendor/laravel/sail/stubs/mailpit.stub:    image: 'axllent/mailpit:latest'

then I run this to remove cache

    php artisan config:clear

Result

    php artisan app:send-event-reminders

    Found 5 events.
    Reminder notifications sent successfully!

check mailpit (localhost:8025)

I set up the mailpit via docker
