Simple FastAPI app that connects to Odoo 16 Community Edition via XML-RPC to list products and update their cost prices.

• Fetch products (ID, name, SKU/internal reference, cost) with search_read.
• Update cost using write on product.product.
• Basic validation: blocks negative costs on both frontend and backend.
• Minimal UI via Jinja2 template + Bootstrap.

• Python 3.10+
• FastAPI + Uvicorn
• XML-RPC (stdlib xmlrpc.client)
• Docker Compose (Odoo + PostgreSQL)
• HTML/Bootstrap/JS (Fetch API)

• main.py - FastAPI app, routes, template rendering.
• services.py - Odoo XML-RPC helpers (auth, fetch, update).
• schemas.py - Pydantic models for request validation.
• config.py - Loads environment variables from .env.
• templates/ - HTML frontend.

git clone <repository-url>
cd odoo-app

docker-compose up -d

Then:

1. Wait for Odoo to initialize.
2. Open http://localhost:8069 and create the database with:
   • Master Password: use the value shown (default is often admin)
   • Database Name: odoo_test (must match .env)
   • Email: admin
   • Password: admin
   • Demo Data: check this box to get sample products
3. Click Create Database.
4. After login, go to Apps and install the Sales module so products exist to test.

python -m venv venv
# Windows
.\venv\Scripts\activate
# macOS/Linux
source venv/bin/activate
pip install -r requirements.txt

Create .env in the project root:

ODOO_URL=http://localhost:8069
ODOO_DB=odoo_test
ODOO_USER=admin
ODOO_PASSWORD=admin

Adjust values to match your Odoo setup.

pytest

• Cost is variant-level in Odoo, so updates target product.product.
• Internal Reference/SKU maps to default_code.
• Uses stdlib XML-RPC; no extra client dependency needed.
