README

Provides a File Model that supports direct uploads / downloads from S3 for a Laravel App.

Installation

  1. composer require rootinc/laravel-s3-file-model
  2. Run php artisan vendor:publish --provider="RootInc\LaravelS3FileModel\FileModelServiceProvider" to create File model in app, FileTest in tests\Unit, FileFactory in database\factories, 2020_03_12_152841_create_files_table in database\migrations, and FileController in app\Http\Controllers
  3. Run php artisan vendor:publish --provider="Aws\Laravel\AwsServiceProvider which adds aws.php in the config folder
  4. In the aws.php file, change 'region' => env('AWS_REGION', 'us-east-1'), to use AWS_DEFAULT_REGION
  5. In config\filesystems.php, add key 'directory' => '', // root dir to public and add key 'directory' => env('AWS_UPLOAD_FOLDER'), to s3
  6. In tests\TestCase, add this function:
protected function get1x1RedPixelImage()
{
    return "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8z8DwHwAFBQIAX8jx0gAAAABJRU5ErkJggg==";
}
  1. Update routing. We can use this as an example: Route::apiResource('files', 'FileController')->only(['index', 'store', 'update', 'destroy']);
  2. 🎉

Update from 0.1.* to 0.2.*

If we are using API versioning paradigm, 0.2.* lets us abstract the file model so that in a child class, we can import a different version of the File.

For example, our FileController would look something like this:

<?php

namespace App\Http\Controllers\Api\v3;

use RootInc\LaravelS3FileModel\FileBaseController;

use ReflectionClass;

use App\Models\v3\File;

class FileController extends FileBaseController
{
    protected static function getFileModel()
    {
        $rc = new ReflectionClass(File::class);
        return $rc->newInstance();
    }
...

Now when running the parent's functionality, it will make use of the right model.

Note -- the FileController's update and delete methods have been switched from public function method(Request $request, File $file) to public function method(Request $request, $file_id)

The same has been updated for tests. That way, if we want to make use of Laravel 8's updated factory classes, we can do so like below:

<?php

namespace Tests\Unit\v2;

use RootInc\LaravelS3FileModel\FileModelTest;

use Tests\DatabaseMigrationsUpTo;

use ReflectionClass;

use App\Models\v2\File;

class FileTest extends FileModelTest
{
    use DatabaseMigrationsUpTo;

    protected static function getFileModel()
    {
        $rc = new ReflectionClass(File::class);
        return $rc->newInstance();
    }

    protected function getFileFactory($count=1, $create=true, $properties=[])
    {
        $files;

        $factory = File::factory()->count($count);
        if ($create)
        {
            $files = $factory->create($properties);
        }
        else
        {
            $files = $factory->make($properties);
        }

        $len = count($files);
        if ($len === 1)
        {
            return $files[0];
        }
        else if ($len === 0)
        {
            return null;
        }
        else
        {
            return $files;
        }
    }
...

Contributing

Thank you for considering contributing to the Laravel S3 File Model! To encourage active collaboration, we encourage pull requests, not just issues.

If you file an issue, the issue should contain a title and a clear description of the issue. You should also include as much relevant information as possible and a code sample that demonstrates the issue. The goal of a issue is to make it easy for yourself - and others - to replicate the bug and develop a fix.
