# Odoo Modules — Claude Code Instructions

## Project
27 custom Odoo 19 modules for Fusion Central (Westin Healthcare + NEXA Systems).

## Critical Rules — Odoo 19
1. **NEVER code from memory** — Always read a reference file from Docker first:
   ```bash
   docker exec odoo-dev-app cat /usr/lib/python3/dist-packages/odoo/addons/<module>/static/src/<path>
   ```
2. **Frontend JS**: Use `Interaction` class from `@web/public/interaction`, registered via `registry.category("public.interactions")`. NOT IIFE/DOMContentLoaded.
3. **Backend OWL**: Use standalone `rpc()` from `@web/core/network/rpc`. NOT `useService("rpc")`. `static props = []` not `{}`.
4. **HTTP routes**: `type="jsonrpc"` — NOT `type="json"` (deprecated).
5. **res.config.settings**: Only boolean/integer/float/char/selection/many2one/datetime. NO Date fields.
6. **res.groups**: NO `users` field, NO `category_id` field.
7. **Search views**: NO `group expand="0"` syntax.
8. **SCSS imports**: `@import "./partial"` is FORBIDDEN in Odoo 19 custom SCSS. It prints a warning and silently falls back to the old cached bundle. Register every SCSS file (including `_partial.scss` tokens) as a separate entry in `web.assets_backend`. Put tokens first; Odoo concatenates bundle files so SCSS variables/mixins from the first file are visible to every later file.

## Card Styling — Copy Odoo's Kanban Pattern
Don't rely on `var(--bs-border-color)` or `var(--bs-body-bg)` for card surfaces — they drift between themes/addons and often render **invisible**. Odoo's own kanban (`.o_kanban_record`) uses **explicit hex** values:
```css
background-color: white;
border: 1px solid #d8dadd;
```
For custom OWL dashboards / client actions use the same approach:
- Define a `_tokens.scss` partial with explicit hex values wrapped in a CSS custom property:
  ```scss
  $fp-card:   var(--fp-card-bg, #ffffff);
  $fp-border: var(--fp-border-color, #d8dadd);
  ```
- Reference those tokens everywhere (never `var(--bs-border-color)` directly)
- Three-layer contrast: **page** (grayest) → **container/column** (mid) → **card** (brightest). That's what makes cards pop.
- Reference implementation: `fusion_plating_shopfloor/static/src/scss/_fp_shopfloor_tokens.scss`.

## Dark Mode — Branch on `$o-webclient-color-scheme` at SCSS Compile Time
Odoo 19 does NOT flip dark mode via a runtime DOM class. It compiles TWO asset bundles:
- `web.assets_backend` — compiled with `$o-webclient-color-scheme: bright`
- `web.assets_web_dark` — compiled with `$o-webclient-color-scheme: dark` (dark variant primary variables loaded first)

Your SCSS file is compiled into BOTH bundles. To make the dark bundle have different colors, **branch at compile time** using the SCSS variable Odoo sets:

```scss
$o-webclient-color-scheme: bright !default;

$_my-page-hex: #f3f4f6;
$_my-card-hex: #ffffff;

@if $o-webclient-color-scheme == dark {
    $_my-page-hex: #1a1d21 !global;
    $_my-card-hex: #22262d !global;
}

$my-page: var(--my-page-bg, $_my-page-hex);
$my-card: var(--my-card-bg, $_my-card-hex);
```

**Do NOT use** `.o_dark_mode` class selectors, `[data-bs-theme="dark"]`, or `@media (prefers-color-scheme: dark)` — none of those fire reliably in Odoo 19. The user toggles dark mode via the user profile, which sets a `color_scheme` cookie and reloads the page; Odoo then serves the dark bundle. Your SCSS `@if` handles the rest at compile time.

Verify by inspecting the attachments — you should see two files with different URLs for the two bundles:
```python
env['ir.qweb']._get_asset_bundle('web.assets_backend').css()     # light
env['ir.qweb']._get_asset_bundle('web.assets_web_dark').css()    # dark
```

## Asset Bundle Cache Busting
Odoo content-hashes the compiled bundle URL (`/web/assets/<hash>/...`). When CSS changes but the hash doesn't update, the browser serves the old bundle. Fixes in order of escalation:
1. Bump the module `version` in `__manifest__.py`
2. `DELETE FROM ir_attachment WHERE url LIKE '/web/assets/%';` then restart odoo
3. Call `env['ir.qweb']._get_asset_bundle('web.assets_backend').css()` in odoo-shell to force regeneration
4. Hard-refresh browser with cache clear (DevTools → right-click refresh → *Empty Cache and Hard Reload*); on mobile clear website data

## Naming
- New fields: `x_fc_*` prefix
- Legacy fields: `x_studio_*`
- Canadian English for all user-facing text
- Currency: `$` sign with Monetary fields + currency_id

## Cursor-Managed Modules
- **fusion_clock** is currently being modified in Cursor — always read files fresh before editing, don't assume you know the current state

## Workflow
- Local dev: `docker exec odoo-dev-app odoo -d fusion-dev -u <module> --stop-after-init`
- Local URL: http://localhost:8069
- Test before deploying. Edit existing files — don't create unnecessary new ones.
