# Fusion WooCommerce — Odoo Module

## What This Is
Bidirectional Odoo 19 ↔ WooCommerce sync module. The "brain" — all sync logic, product mapping, scheduling, conflict resolution, and dashboards live here. Pairs with the `fusion-woodoo` WordPress plugin (thin display layer).

## Architecture
- **Odoo calls WC** via REST API v3 (consumer key/secret auth)
- **WC calls Odoo** via webhooks (HMAC signature auth) and the WP plugin calls custom endpoints (bearer token auth)
- **Hybrid sync**: real-time webhooks + scheduled cron fallback + manual "Sync Now"

## Critical Odoo 19 Rules
1. **Views**: `<list>` NOT `<tree>`. `view_mode` uses `list,form` NOT `tree,form`.
2. **Search views**: NO `<group expand="...">` wrapper — use bare `<filter>` with `<separator/>`.
3. **No `attrs`**: Use inline `invisible="..."` / `readonly="..."` / `required="..."` directly.
4. **No `states`**: Use `invisible="state != 'draft'"` instead.
5. **HTTP routes**: `type="jsonrpc"` for internal. `type="http"` with `csrf=False` for WC webhooks (WC sends raw JSON, not JSON-RPC).
6. **OWL**: standalone `rpc()` from `@web/core/network/rpc`. `static props = []`. No globals like `Number()` in templates — use component methods.
7. **res.groups**: NO `category_id` field.
8. **API client in `lib/`** NOT `models/` — plain Python class, not an Odoo model.

## Key Files
```
lib/woo_api_client.py          — WC REST API wrapper (NOT an Odoo model)
models/woo_instance.py         — Core: connection config, sync methods, cron entry points
models/woo_product_map.py      — Product mapping + price sync methods
models/woo_order.py            — Order tracking + status push methods
controllers/webhook.py         — Receives WC webhooks (type="http", HMAC auth)
controllers/api.py             — REST endpoints for WP plugin (type="jsonrpc", bearer auth)
controllers/product_search.py  — AJAX search for OWL mapping UI
static/src/js/product_mapping.js  — OWL product mapping client action
static/src/js/dashboard.js     — OWL dashboard client action
static/src/js/theme_detect.js  — Reads color_scheme cookie, sets data-woo-theme on <html>
static/src/css/woo_styles.css  — Theme-aware CSS using var(--woo-*) custom properties
```

## Dark Mode
- Odoo 19 stores dark mode in `color_scheme` cookie ("dark" or "bright")
- `theme_detect.js` reads the cookie and sets `data-woo-theme="dark"` on `<html>`
- All CSS uses `var(--woo-*)` custom properties with dark overrides under `html[data-woo-theme="dark"]`
- NEVER use hardcoded colours in templates — use `woo-badge-*`, `woo-text-muted`, `woo-code` classes
- NEVER use Bootstrap colour classes (`bg-primary`, `text-dark`, etc.) in OWL templates

## WC Pricing Model
- WooCommerce has two prices: `regular_price` (standard) and `sale_price`
- Stored as `woo_regular_price` and `woo_sale_price` on `woo.product.map`
- Sync logic: if standard price is zero → sync sets regular_price. If standard exists → sync sets sale_price
- Standard price can never be less than sale price — validation enforced

## Deployment
```bash
# Deploy to westin
ssh odoo-westin "rm -rf /opt/odoo/custom-addons/fusion_woocommerce"
scp -r fusion-woo-odoo/fusion_woocommerce odoo-westin:/opt/odoo/custom-addons/fusion_woocommerce
ssh odoo-westin "docker exec odoo-dev-app odoo -d westin-v19 -u fusion_woocommerce --stop-after-init --no-http"

# IMPORTANT: Clear asset cache after JS/CSS changes
ssh odoo-westin "docker exec odoo-dev-db psql -U odoo -d westin-v19 -c \"DELETE FROM ir_attachment WHERE name LIKE '%assets_backend%' OR url LIKE '%/web/assets%';\""
ssh odoo-westin "docker restart odoo-dev-app"
```

## Gotchas
- Health check cron only logs — never changes instance state (Docker can't reach external URLs)
- Product map state stays `mapped` even on sync errors/conflicts — conflicts tracked separately in `woo.conflict`
- Search endpoints return `{"results": [...], "total": count}` for pagination
- Existing products are skipped during fetch (dedup by `woo_product_id` + `instance_id`)
- After adding new DB fields, must run `-u fusion_woocommerce` before backfilling data
