Campaign slug was lost during email registration flow — it was only
sent at verification time from localStorage, which is empty if the
user opens the verification link in a different browser/webview.
Now campaign_slug is accepted in the registration request, saved to
user.pending_campaign_slug, and used as fallback during email
verification. Also processed immediately for auto-verified test emails.
- Include LIMITED status in subscription lookups (get_active_subscriptions_by_user_id, get_subscription_by_user_and_tariff) — fixes duplicate subscriptions when traffic exhausted
- Migration 0053: update partial unique index to include LIMITED
- Trial subscriptions no longer block tariff purchase — excluded from purchased_tariff_ids, handle_extend_subscription routes trial+tariff to tariff extend flow
- Replace hardcoded TrafficLimitStrategy.MONTH with get_traffic_reset_strategy() across all sync/create paths (remnawave_service, monitoring_service, admin_users)
- Subscriptions with tariff_id always use tariff pricing flow regardless of global sales mode — fixes 0₽ renewal in classic mode
- Support 100% promo group discount across all purchase/renewal flows — balance checks skip when price=0, validation allows final_total=0 when base_price>0
- Add tariff_id column to promocodes table (migration 0052)
- Admin can now select any tariff when creating trial_subscription promo
- Activation uses promocode.tariff_id if set, falls back to system
trial tariff
- Multi-tariff: blocks trial only if user already has that specific tariff
- Add news_categories and news_tags tables with case-insensitive unique names
- Add category_id/tag_id FK columns to news_articles (ON DELETE SET NULL)
- CRUD endpoints for categories and tags (admin permissions)
- Sync legacy string fields from FK entities on create/update
- Clear legacy fields on category/tag deletion
- Alembic migration 0049 with backfill from existing article data
- Fix orphaned subscriptions/GuestPurchase when phantom claim fails with
IntegrityError — now merges phantom into existing user across all 3 call sites
- Add explicit db.commit() after merge in both active-user and registration paths
- Fix remnawave_uuid transfer ordering (clear→flush→assign) to prevent unique
constraint violation during flush
- Clear phantom.referral_code on soft-delete to prevent unique constraint issues
- Add status != DELETED filter to find_phantom_user_by_username (defense in depth)
- Add WARNING-level logging on phantom claims for admin audit trail
- Add functional index on lower(username) for phantom lookup performance (migration 0048)
- Add ON DELETE CASCADE to subscription_servers.subscription_id (migration 0047)
- Add admin endpoint POST /users/{id}/assign-referrer with recursive CTE cycle
detection, self-enrichment prevention, and audit logging
- Harden account_merge_service: add SubscriptionServer, RioPayPayment,
SeverPayPayment, SavedPaymentMethod, GuestPurchase, NewsArticle handling
- Fix logger key typo get= → error= in promocode activation
- Server-side HTML sanitization for article content
- URL scheme validation for featured_image_url (http/https only)
- Slug sanitization on create/update
- MissingGreenlet fix in delete (capture attrs before commit)
- Missing rollback after IntegrityError in CRUD
- nullslast() for published_at ordering
- asyncio.gather for parallel DB queries
- Removed selectinload(author) from list queries
- increment_views with RETURNING (no extra SELECT)
- Migration-model index alignment
- Pre-compiled regex, structlog.exception pattern
- View counter dedup cache (5min TTL)
- Create NaloGO receipt when code-only gifts (no recipient) are paid via
any gateway provider, not just directed gifts
- Add receipt_uuid and receipt_created_at columns to guest_purchases for
persistent DB-level dedup (covers PENDING_ACTIVATION and code-only paths
where no Transaction exists at receipt time)
- Use SELECT ... FOR UPDATE in try_fulfill_guest_purchase to prevent
concurrent webhook double-processing race condition
- Expand idempotency guard to include code-only gifts already in PAID status
- Add db.refresh after PENDING_ACTIVATION nalogo call to guard against
inner rollback expiring the ORM object
Cabinet API and WebAPI created admin balance transactions with
payment_method=NULL instead of 'manual', making them invisible
to sales statistics filters.
Changes:
- Add payment_method=PaymentMethod.MANUAL to Cabinet and WebAPI
balance update endpoints
- Add func.abs() to all transaction amount aggregations missing it
across sales stats, dashboard stats, and reporting queries
- Remove redundant Python abs() on addon_revenue (SQL func.abs
already applied)
- Add data migration 0044 to fix historical NULL payment_method
records for admin top-ups
payload column in cryptobot_payments contains plain strings like
"balance_2_10000" alongside JSON objects. CAST(payload AS json) fails
on these rows during CREATE INDEX CONCURRENTLY.
- Add AND payload LIKE '{%' to partial index WHERE clause in migration 0042
- Add .payload.like('{%') filter to guest_purchase_service query
- bootstrap _assign_if_missing no longer reactivates revoked UserRole rows
- revoke_role uses SELECT FOR UPDATE + pg_advisory_xact_lock to prevent TOCTOU race on last-superadmin check
- block self-revocation of superadmin role
- block is_active/level changes on system roles
- block expires_at on superadmin role assignments
- single SUPERADMIN_LEVEL constant in crud/rbac.py, imported everywhere
- get_superadmin_count excludes expired assignments
- removed dead UserRoleCRUD.revoke_role method
- warn when revoking RBAC role from a legacy ADMIN_IDS user
- added migration 0043: indexes on user_roles.role_id, access_policies.role_id, lower(users.email)
- Add retry_count column to guest_purchases with Alembic migration
- Add expression indexes on metadata_json->>'purchase_token' for all 12
payment provider tables (partial indexes filtered by is_paid/status)
- Implement _find_succeeded_provider_payment() covering all providers:
YooKassa, Heleket, MulenPay, Pal24, Wata, Platega, CloudPayments,
Freekassa, KassaAi, RioPay, SeverPay, and CryptoBot (payload field)
- Add amount verification in _check_and_recover_pending_purchase():
compares provider payment amount with GuestPurchase.amount_kopeks,
skips for CryptoBot (USD conversion imprecision)
- Increment retry_count on each retry attempt in retry_stuck_paid_purchases
and retry_stuck_pending_activation
- Mark purchases as FAILED after 20 retries with admin Telegram alert
via AdminNotificationService (ERRORS category)
Add composite indexes on advertising_campaign_registrations(user_id,
created_at) and transactions(user_id, type, is_completed, amount_kopeks)
to enable index-only scans. Uses CREATE INDEX CONCURRENTLY for zero
downtime. Also enable transaction_per_migration in Alembic env.py.

- Миграция: добавлено пересоздание FK с ON DELETE SET NULL
- get_latest_payment_by_method: добавлен RioPayPayment в model_map
Add a per-tariff visibility flag (show_in_gift) that controls whether
a tariff appears in the /gift section. Enforced server-side in gift
config query, gift purchase endpoint, and landing page gift purchases.
Includes Alembic migration with idempotency guard and server_default.
1. Truncate tokens to 12 chars in all API responses (SentGift,
PendingGift, ReceivedGift, PurchaseStatus, PurchaseResponse,
return URL) — full token no longer leaves the server
2. Status endpoint supports prefix-based token lookup
3. create_paid_subscription/replace_subscription accept commit=False
— activate_purchase now uses single atomic commit for subscription
+ purchase status update (fixes double-commit gap)
4. Bot handler uses flush() instead of commit() before svc_activate
— consistent with cabinet endpoint, allows rollback on failure
5. Add retry_stuck_pending_activation() for purchases stuck in
PENDING_ACTIVATION status (10 min threshold)
6. Add varchar_pattern_ops index for prefix queries on token column
- Replace 501 stub with full gateway payment flow via PaymentService
- Move telegram username pre-check (DB-first) above gateway/balance branch
- Add recipient_warning column to GuestPurchase model + migration 0034
- Return warning in gift purchase status endpoint
- Add db.refresh(purchase) after commit in gateway branch
- Add source column (landing/cabinet) to track purchase origin
- Add buyer_user_id FK to link cabinet gift purchases to authenticated users
- Add GIFT_PAYMENT to TransactionType enum for balance deductions
- Add foreign_keys disambiguation to existing user relationship
- Migration 0032: adds columns, index on source, FK constraint
Migrations 0019, 0022, 0031 crashed with UndefinedTableError when
payment provider tables (e.g. kassa_ai_payments) or contest_templates
did not exist. Added _table_exists() checks before ALTER/DROP operations.
