Subscription Module – Laravel Refactor

This module is a full Laravel refactor of a legacy Yii2 subscription slice. The goal was to rebuild the module using clean Laravel architecture, proper authorization, a complete trial system, performance fixes, and automated workflows — all supported with a full test suite.

---

Key Features

Clean Architecture

• Business logic moved out of controllers
• Models contain only entity logic
• Policies handle all authorization
• Commands and Jobs manage automation
• Blade views contain zero business logic

Trial System

• 7-day trial automatically created
• Expired trials automatically converted to paid
• Email notification dispatched through a queued Job

---

Performance – N+1 Fix

The original code suffered from N+1 queries.

The fix uses eager loading:

Subscription::with(['user', 'plan'])

This reduces the query count to:

• 1 query for subscriptions
• 1 query for users
• 1 query for plans

N+1 Proof

---

Security & Authorization

Authorization is handled via SubscriptionPolicy:

• Admins → full access
• Users → can only view/cancel their own subscriptions

Controllers enforce this using:

$this->authorize('view', $subscription);

and:

$this->authorize('cancel', $subscription);

---

Automation (Command + Queue)

Daily Command

php artisan subscriptions:convert-trials

• Detects expired trials
• Converts them into paid subscriptions
• Dispatches a queue job for email notification

Job: SendSubscriptionEmailJob

• Queue-driven
• Sends a SubscriptionEmail mailable
• Fully isolated from controller logic

---

Test Coverage

Covers:

• Trial conversion logic
• Queue job dispatching
• Authorization access rules
• Model helpers & scopes
• Email sending behavior
• Feature-level endpoint access

All tests pass:

OK (10 tests, 30 assertions)
