# Migration Consolidation - Next Steps

**Status:** ✅ Consolidation Complete - Ready for Verification  
**Date:** January 16, 2025

---

## Quick Commands Reference

### 1. Run Automated Verification (5 minutes)

```bash
cd attune
./scripts/verify_migrations.sh
```

**Expected Output:**
- ✓ Test database created
- ✓ 18 tables created
- ✓ 12 enums defined
- ✓ 100+ indexes created
- ✓ 30+ foreign keys created
- ✓ Basic inserts working

---

### 2. Update SQLx Query Cache (10 minutes)

```bash
# Ensure PostgreSQL is running
docker-compose up -d postgres

# Set database URL
export DATABASE_URL="postgresql://postgres:postgres@localhost:5432/attune"

# Drop and recreate development database
dropdb -U postgres attune 2>/dev/null || true
createdb -U postgres attune

# Apply new migrations
sqlx migrate run

# Update query cache for all services
cargo sqlx prepare --workspace
```

---

### 3. Run Integration Tests (15 minutes)

```bash
# Run all tests
cargo test --workspace

# Or run specific test suites
cargo test -p attune-api --test integration_tests
cargo test -p attune-common --lib
```

---

### 4. Verify Compilation (5 minutes)

```bash
# Build entire workspace
cargo build --workspace

# Check for warnings
cargo clippy --workspace
```

---

### 5. Clean Up (2 minutes)

```bash
# After successful verification, delete old migrations
rm -rf migrations/old_migrations_backup/

# Stage changes
git add -A

# Commit
git commit -m "feat: consolidate database migrations from 18 to 5 files

- Reduced migration files from 18 to 5 (-72%)
- Incorporated all 6 patches into base migrations
- Resolved forward reference dependencies
- Improved logical grouping by domain
- Fixed sensor service compilation error
- Updated comprehensive documentation

All 18 tables, 12 enums, 100+ indexes preserved.
Old migrations backed up for reference."
```

## Issues Fixed

### ✅ Sensor Service Compilation (2 Errors Fixed)

#### 1. Missing field in Rule query
- **Problem:** Missing `trigger_params` field in Rule query
- **File:** `crates/sensor/src/rule_matcher.rs:129`
- **Fix:** Added `trigger_params` to SELECT clause
- **Status:** Fixed ✅

#### 2. Missing field in test helper
- **Problem:** Missing `trigger_params` field in test Rule creation
- **File:** `crates/sensor/src/rule_matcher.rs:499`
- **Fix:** Added `trigger_params` to `test_rule()` helper function
- **Status:** Fixed ✅

## Troubleshooting

### Issue: SQLx compilation errors
**Solution:** Run `cargo sqlx prepare --workspace`

### Issue: Database connection failed
**Solution:** 
```bash
docker-compose up -d postgres
# Wait 5 seconds for PostgreSQL to start
sleep 5
```

### Issue: Migration already applied
**Solution:**
```bash
dropdb -U postgres attune
createdb -U postgres attune
sqlx migrate run
```

### Issue: Test failures
**Solution:** Check that test database is using new migrations:
```bash
dropdb -U postgres attune_test
createdb -U postgres attune_test
DATABASE_URL="postgresql://postgres:postgres@localhost:5432/attune_test" sqlx migrate run
```
