- Added API endpoints for tag management (create, read, update, delete). - Implemented entity tagging functionality to associate tags with various entities. - Created workflow management for tag-triggered actions. - Developed frontend views for tag administration using FastAPI and Jinja2. - Designed HTML template for tag management interface with Bootstrap styling. - Added JavaScript for tag picker component with keyboard shortcuts and dynamic tag filtering. - Created database migration scripts for tags, entity_tags, and tag_workflows tables. - Included default tags for initial setup in the database.

Opret nyt modul
python scripts/create_module.py my_module "My Module Description"
Database Tables
Alle tabeller SKAL bruge table_prefix fra module.json:
-- Hvis table_prefix = "mymod_"
CREATE TABLE mymod_items (
id SERIAL PRIMARY KEY,
name VARCHAR(255)
);
Dette sikrer at moduler ikke kolliderer med core eller andre moduler.
Customer Linking (Hvis nødvendigt)
Hvis dit modul skal have sin egen kunde-tabel (f.eks. ved sync fra eksternt system):
SKAL altid linke til core customers:
CREATE TABLE mymod_customers (
id SERIAL PRIMARY KEY,
name VARCHAR(255) NOT NULL,
external_id VARCHAR(100), -- ID fra eksternt system
hub_customer_id INTEGER REFERENCES customers(id), -- VIGTIG!
active BOOLEAN DEFAULT TRUE,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
-- Auto-link trigger (se migrations/001_init.sql for komplet eksempel)
CREATE TRIGGER trigger_auto_link_mymod_customer
BEFORE INSERT OR UPDATE OF name
ON mymod_customers
FOR EACH ROW
EXECUTE FUNCTION auto_link_mymod_customer();
Hvorfor? Dette sikrer at:
- ✅ E-conomic export virker automatisk
- ✅ Billing integration fungerer
- ✅ Ingen manuel linking nødvendig
Alternativ: Hvis modulet kun har simple kunde-relationer, brug direkte FK:
CREATE TABLE mymod_orders (
id SERIAL PRIMARY KEY,
customer_id INTEGER REFERENCES customers(id) -- Direkte link
);
Konfiguration
Modul-specifikke miljøvariable følger mønsteret:
MODULES__MY_MODULE__API_KEY=secret123
MODULES__MY_MODULE__READ_ONLY=true
Tilgå i kode:
from app.core.config import get_module_config
api_key = get_module_config("my_module", "API_KEY")
read_only = get_module_config("my_module", "READ_ONLY", default="true") == "true"
Database Queries
Brug ALTID helper functions fra app.core.database:
from app.core.database import execute_query, execute_insert
# Fetch
customers = execute_query(
"SELECT * FROM mymod_customers WHERE active = %s",
(True,)
)
# Insert
customer_id = execute_insert(
"INSERT INTO mymod_customers (name) VALUES (%s)",
("Test Customer",)
)
Migrations
Migrations ligger i migrations/ og køres manuelt eller via migration tool:
from app.core.database import execute_module_migration
with open("migrations/001_init.sql") as f:
migration_sql = f.read()
success = execute_module_migration("my_module", migration_sql)
Enable/Disable
# Enable via API
curl -X POST http://localhost:8000/api/v1/modules/my_module/enable
# Eller rediger module.json
{
"enabled": true
}
# Restart app
docker-compose restart api
Fejlhåndtering
Moduler er isolerede - hvis dit modul crasher ved opstart:
- Core systemet kører videre
- Modulet bliver ikke loaded
- Fejl logges til console og logs/app.log
Runtime fejl i endpoints påvirker ikke andre moduler.
Testing
import pytest
from app.core.database import execute_query
def test_my_module():
# Test bruger samme database helpers
result = execute_query("SELECT 1 as test")
assert result[0]["test"] == 1
Best Practices
- Database isolering: Brug ALTID
table_prefixfra module.json - Safety switches: Tilføj
READ_ONLYogDRY_RUNflags - Error handling: Log fejl, raise HTTPException med status codes
- Dependencies: Deklarer i
module.jsonhvis du bruger andre moduler - Migrations: Nummer sekventielt (001, 002, 003...)
- Documentation: Opdater README.md med API endpoints og use cases
