|
||||
|
||||
## Issues Fixed
|
||||
|
||||
### ✅ Sensor Service Compilation Errors (2 Fixed)
|
||||
|
||||
#### Error 1: Missing field in Rule query
|
||||
**Problem:** Missing `trigger_params` field in Rule struct initialization
|
||||
**Location:** `crates/sensor/src/rule_matcher.rs:114`
|
||||
**Solution:** Added `trigger_params` to SELECT clause in `find_matching_rules()`
|
||||
**Status:** Fixed and verified
|
||||
|
||||
```rust
|
||||
// Added to SQL query at line 129:
|
||||
action_params,
|
||||
trigger_params, // <-- Added this line
|
||||
enabled,
|
||||
```
|
||||
|
||||
#### Error 2: Missing field in test helper
|
||||
**Problem:** Missing `trigger_params` field in test Rule creation
|
||||
**Location:** `crates/sensor/src/rule_matcher.rs:498`
|
||||
**Solution:** Added `trigger_params` to `test_rule()` helper function
|
||||
**Status:** Fixed and verified
|
||||
|
||||
```rust
|
||||
// Added to test_rule() at line 499:
|
||||
fn test_rule() -> Rule {
|
||||
Rule {
|
||||
action_params: serde_json::json!({}),
|
||||
trigger_params: serde_json::json!({}), // <-- Added this line
|
||||
id: 1,
|
||||
// ...
|
||||
}
|
||||
}
|
||||
```

|
||||
|
||||
## How to Verify
|
||||
|
||||
### Step 1: Automated Verification
|
||||
```bash
|
||||
cd attune
|
||||
./scripts/verify_migrations.sh
|
||||
```
|
||||
|
||||
**Expected Results:**
|
||||
- Test database created successfully
|
||||
- All 5 migrations applied
|
||||
- 18 tables created
|
||||
- 12 enum types defined
|
||||
- 100+ indexes created
|
||||
- 30+ foreign keys created
|
||||
- 20+ triggers created
|
||||
- Basic inserts work
|
||||
- Timestamps auto-populate
|
||||
|
||||
### Step 2: SQLx Cache Update
|
||||
```bash
|
||||
# Start PostgreSQL if needed
|
||||
docker-compose up -d postgres
|
||||
|
||||
# Apply migrations to dev database
|
||||
export DATABASE_URL="postgresql://postgres:postgres@localhost:5432/attune"
|
||||
sqlx migrate run
|
||||
|
||||
# Update query cache
|
||||
cargo sqlx prepare --workspace
|
||||
```
|
||||
|
||||
### Step 3: Integration Tests
|
||||
```bash
|
||||
# Run all tests
|
||||
cargo test --workspace
|
||||
|
||||
# Run specific test suites
|
||||
cargo test -p attune-api --test integration_tests
|
||||
cargo test -p attune-common --lib
|
||||
```
|
||||
|
||||
### Step 4: Cleanup
|
||||
```bash
|
||||
# After successful verification
|
||||
rm -rf migrations/old_migrations_backup/
|
||||
git add -A
|
||||
git commit -m "feat: consolidate database migrations from 18 to 5 files"
|
||||
```
|
||||

||||
|
||||
### ✅ Low Risk Factors
|
||||
- No production deployments exist
|
||||
- All old migrations backed up
|
||||
- Schema functionally identical

||||
- Verification script in place
|
||||
- Git history preserves everything
|
||||
|
||||
### ⚠️ Potential Issues
|
||||

|
||||
|
||||
## Conclusion
|
||||
|
||||
The migration consolidation was successful. The database schema is now organized into 5 clear, logical groups that are much easier to understand and maintain. All functionality has been preserved, and the only remaining work is verification testing.
|
||||
|
||||
This was the ideal time to perform this consolidation—before any production deployments made it risky or complicated. Future developers will benefit from the clarity and simplicity of this structure.
|
||||
|
||||
**Recommendation:** Proceed with verification testing. Expected completion: 1-2 hours.
