Enhancing Auto-Sync Functionality: Excluding Already-Used Commits

Introduction

In our recent development effort, we aimed to enhance the auto-sync functionality in our post generation system. The primary concern was to ensure that commits already used in existing posts would not be duplicated in the auto-sync process. This adjustment was necessary to maintain the integrity and uniqueness of the posts generated by our system.

The Challenge

Previously, our auto-sync feature did not account for commits that had already been associated with posts. This led to a situation where users might see duplicate content, which could confuse readers and diminish the overall value of the posts. We needed a solution that could effectively filter out these used commits while still ensuring that newly generated posts were unique and fresh.

The Solution

To tackle this issue, we implemented a test in our AutoSyncPostGenerationJobTest.php that verifies whether the auto-sync process excludes commits already linked to existing posts. This was achieved using Eloquent's whereDoesntHave method to filter out those commits. Here’s a breakdown of the implementation:

Code Implementation

We added a new test case in our test suite:

#[Test]
public function it_excludes_commits_already_used_in_posts(): void
{
    Mail::fake();

    $postExample = PostExample::factory()->create();

    $templatePost = Post::factory()->create([
        'user_id' => $this->user->id,
        'post_example_id' => $postExample->id,
        'language' => 'en',
        'created_at' => now()->subDay(),
    ]);

    $usedCommit = Commit::factory()->create([
        'user_id' => $this->user->id,
        'created_at' => now(),
    ]);

    $existingPost = Post::factory()->create([
        'user_id' => $this->user->id,
    ]);
    $existingPost->commits()->attach($usedCommit->id);

    $job = new AutoSyncPostGenerationJob($this->tenant);
    app()->call([$job, 'handle']);

    app(TenantManager::class)->setTenant($this->tenant);

    $this->assertDatabaseCount('posts', 2, 'tenant');

    Mail::assertNothingSent();
}

Key Decisions

1. Testing Framework: We employed Laravel's built-in testing methods, utilizing Mail::fake() to ensure no emails were sent during the test runs. This keeps our tests self-contained and focused on their specific logic without side effects.
2. Database Factories: By leveraging database factories for generating posts and commits, we ensure that our tests have a consistent and controlled environment, which is crucial for reliable test outcomes.
3. Isolation of Concerns: Using the whereDoesntHave method isolates our concerns by ensuring that only unused commits are processed, thereby upholding the integrity of the generated content.

Results

Following this implementation, the auto-sync functionality now correctly filters out commits associated with already existing posts. This enhancement not only improves content quality but also contributes to a more seamless experience for our users.

Conclusion

Optimizing how we handle commit associations in our auto-sync process has been a significant step towards enhancing the robustness of our content generation features. By ensuring that only unique content is propagated, we minimize redundancy and maximize the value provided to our users.

This experience reinforced the importance of thorough testing in the development process, highlighting how even small changes can significantly affect the behavior of our application. We aim to continue refining our workflows, always aiming for greater efficiency and user satisfaction.
