## 🔍 Common Scenarios
|
|
|
|
### Scenario 1: Student Submits Thesis
|
|
1. Create record in `theses` (is_published=0)
|
|
2. Add author to `authors`, link via `thesis_authors`
|
|
3. Add supervisor(s) to `supervisors`, link via `thesis_supervisors`
|
|
4. Set `orientation_id`, `ap_program_id`, `finality_id`
|
|
5. Upload file to `thesis_files`
|
|
6. Add keywords via `thesis_keywords`
|
|
7. Set `submitted_at` timestamp
|
|
|
|
### Scenario 2: Admin Publishes Thesis
|
|
1. Verify all required fields present
|
|
2. Set `defense_date`
|
|
3. Set `jury_points`
|
|
4. Optional: add `context_note`
|
|
5. Set `is_published = 1`
|
|
6. Set `published_at = CURRENT_TIMESTAMP`
|
|
|
|
### Scenario 3: Public User Searches
|
|
Query `v_theses_public` view with filters:
|
|
- By year
|
|
- By orientation
|
|
- By keyword
|
|
- By author name
|
|
- Full-text search in title/synopsis
|
|
|
|
## 🛠️ Development Workflow
|
|
|
|
### Local Development
|
|
1. Use `test.db` for development
|
|
2. Create via `just init-test-db`
|
|
3. Populate with `just create-fixtures`
|
|
4. Test queries before deployment
|
|
|
|
### Schema Changes
|
|
1. Update `schema.sql`
|
|
2. Update `DATABASE_SPECIFICATION.md`
|
|
3. Test on `test.db`
|
|
4. Deploy to production (manual migration)
|
|
|
|
### Testing
|
|
```bash
|
|
# Run tests on local database
|
|
just test-public-all
|
|
|
|
# Check database stats
|
|
just stats-public
|
|
```
