# Database Migrations Guide

## Quick Overview

When deploying Pounce to a new server, these tables need to be created:

```
✅ Core Tables (17) - User, Subscription, Domain, TLD, etc.
🆕 New Tables (6)  - Listings, Sniper Alerts, SEO Data
```

---

## Automatic Migration

The easiest way to create all tables:

```bash
cd backend
source venv/bin/activate
python scripts/init_db.py
```

This creates all tables from the SQLAlchemy models automatically.

---

## Manual SQL Migration

If you need to run migrations manually (e.g., on an existing database), use the SQL below.

### NEW Table 1: Domain Listings (For Sale Marketplace)

```sql
-- Main listing table
CREATE TABLE domain_listings (
    id SERIAL PRIMARY KEY,
    user_id INTEGER NOT NULL REFERENCES users(id),
    domain VARCHAR(255) NOT NULL UNIQUE,
    slug VARCHAR(300) NOT NULL UNIQUE,

    name VARCHAR(100) NOT NULL,
    email VARCHAR(255) NOT NULL,
    phone VARCHAR(50),
    company VARCHAR(200),

| `subscriptions` | Subscription plans (Scout, Trader, Tycoon) |
| `domains` | Tracked domains in watchlists |
| `domain_checks` | Domain availability check history |
| `tld_prices` | TLD price history (886+ TLDs) |
| `tld_info` | TLD metadata and categories |
| `portfolio_domains` | User-owned domains |
| `domain_valuations` | Domain valuation history |

| `newsletter_subscribers` | Email newsletter list |
| `price_alerts` | TLD price change alerts |

### New Tables (v2.0)

| Table | Purpose | Required For |

| `domain_listings` | For Sale marketplace | `/command/listings`, `/buy` |
| `listing_inquiries` | Buyer messages | Marketplace inquiries |
| `listing_views` | View analytics | Listing stats |

---

## Verification

After migration, verify all tables exist:

```sql
-- PostgreSQL
SELECT table_name 
FROM information_schema.tables 
WHERE table_schema = 'public' 
ORDER BY table_name;

-- Should include:
-- domain_listings
-- listing_inquiries
-- listing_views
-- sniper_alerts
-- sniper_alert_matches
-- domain_seo_data
```

---

## Environment Variables for New Features

### Moz API (Optional - for real SEO data)

```env
MOZ_ACCESS_ID=your_moz_access_id
MOZ_SECRET_KEY=your_moz_secret_key
```

Without these variables, the SEO analyzer uses **estimation mode** based on domain characteristics (length, TLD, keywords).

### Stripe (Required for payments)

```env
STRIPE_SECRET_KEY=sk_live_xxx
STRIPE_WEBHOOK_SECRET=whsec_xxx
STRIPE_PRICE_TRADER=price_xxx  # €9/month
STRIPE_PRICE_TYCOON=price_xxx  # €29/month
```

---

## Scheduler Jobs

These background jobs run automatically when the backend starts:

| Job | Schedule | Table Affected |
|-----|----------|----------------|
| Sniper Alert Matching | Every 15 min | `sniper_alert_matches` |
| Auction Scrape | Hourly | `domain_auctions` |
| TLD Price Scrape | Daily 03:00 | `tld_prices` |
| Domain Check | Daily 06:00 | `domain_checks` |

---

## Rollback

If you need to remove the new tables:

```sql
DROP TABLE IF EXISTS sniper_alert_matches CASCADE;
DROP TABLE IF EXISTS sniper_alerts CASCADE;
DROP TABLE IF EXISTS listing_views CASCADE;
DROP TABLE IF EXISTS listing_inquiries CASCADE;
DROP TABLE IF EXISTS domain_listings CASCADE;
DROP TABLE IF EXISTS domain_seo_data CASCADE;
```
