From 9ac21fca7289e5631c5cbcb43bb8444963fee195 Mon Sep 17 00:00:00 2001 From: William Valentin Date: Sat, 1 Nov 2025 13:26:00 -0700 Subject: [PATCH] feat: migrate Event and Reward models from MongoDB to CouchDB MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Replace Event model with CouchDB version using couchdbService - Replace Reward model with CouchDB version using couchdbService - Update event and reward routes to use new model interfaces - Handle participant management with embedded user data - Maintain status transitions for events (upcoming, ongoing, completed, cancelled) - Preserve catalog functionality and premium vs regular rewards - Update validators to accept CouchDB document IDs - Add rewards design document to couchdbService - Update test helpers for new model structure - Initialize CouchDB alongside MongoDB in server.js for backward compatibility - Fix linting issues in migrated routes 🤖 Generated with [AI Assistant] Co-Authored-By: AI Assistant --- backend/__tests__/utils/testHelpers.js | 23 +- .../middleware/validators/eventValidator.js | 6 +- .../middleware/validators/rewardValidator.js | 6 +- backend/models/Event.js | 249 ++++++++++--- backend/models/Reward.js | 296 ++++++++++++++-- backend/routes/events.js | 328 ++++++++++++++---- backend/routes/rewards.js | 259 ++++++++++---- backend/server.js | 9 +- backend/services/couchdbService.js | 31 ++ 9 files changed, 1006 insertions(+), 201 deletions(-) diff --git a/backend/__tests__/utils/testHelpers.js b/backend/__tests__/utils/testHelpers.js index 765fbba..7800d3e 100644 --- a/backend/__tests__/utils/testHelpers.js +++ b/backend/__tests__/utils/testHelpers.js @@ -134,12 +134,20 @@ async function createTestEvent(userId, overrides = {}) { const defaultEvent = { title: 'Test Event', description: 'Test event description', - date: new Date(Date.now() + 86400000), // Tomorrow + date: new Date(Date.now() + 86400000).toISOString(), // Tomorrow location: 'Test Location', - organizer: userId, };
