# Acai CMS — Project Instructions

This is an Acai CMS website project. Follow these instructions when working with the codebase.

## Environment

- The site runs in Docker, typically at **http://localhost:8080**
- You can make HTTP requests to test pages, APIs, or form submissions
- If you need to inspect the live site, use browser tools (Playwright MCP) or HTTP requests to localhost:8080

## Key Concepts

### Modules (`template/estandar/modulos/`)
Visual components that the site builder uses. Each module is a self-contained unit with its own template (Twig + Acai attributes), CSS, and JS. Modules are placed on pages via the drag-and-drop builder. The editable file is always `index-base.tpl`.

- Include other modules: `<module_id :param1="value1"></module_id>`
- Each module instance gets a unique `section_id` variable for anchors/scoping
- Use `interno` variable to detect CMS editor mode vs public view

See [docs/modular-system.md](docs/modular-system.md) for detailed rules.

### General Sections
Database-backed templates (headers, footers, record views) that use the `thisrecord` variable to access record fields. They use the same Twig + Acai attribute engine as modules.

- Upload fields return arrays: `thisrecord.image[0].urlPath`
- Foreign keys use `_num` suffix: `category_num`

See [docs/modular-system.md](docs/modular-system.md) for details.

### Hooks (`hooks/`)
PHP files that execute server-side logic. Triggered by:
- Twig filter: `'hooks/module_id/' | hook({param: value})`
- HTML tag: `<hook result="var" endpoint="/hooks/module_id/" :param="value"></hook>`
- JavaScript: `CmsApi.hook('/hooks/module_id/', {param: value}, callback)`
- Form action: via `c-form` attribute

See [docs/hooks-and-api.md](docs/hooks-and-api.md) for usage.

## Database Access

When the site is running in Docker, you can connect to the database:

- **Host:** `127.0.0.1`
- **Port:** Check `.docker/docker-compose.yml` for the mapped port (usually 3307+)
- **Credentials:** Read from `.docker/.env`:
  - `DB_USERNAME`
  - `DB_PASSWORD`
  - `DB_DATABASE`

```bash
docker exec -it dw-<project-name>-db mysql -u root -p<password> <database>
```

**Important:** Table names in CmsApi/Twig do NOT use the `cms_` prefix. The primary key is always `num`, never `id`.

## Acai Core (web-base)

The project workspace contains only the **customization layer** (modules, hooks, schemas, uploads). The CMS core (routing, rendering engine, admin panel, APIs) lives in a separate directory called **web-base** that is mounted as a Docker volume.

The web-base path can be obtained via: `GET http://localhost:9090/api/web-base-path`

Do NOT modify web-base files — they are shared across all projects.

## Critical Rules

1. Only edit `index-base.tpl` in modules — `index.tpl`, `index-twig.tpl`, and `builder.json` are auto-generated
2. Use Twig **filters** (with `|`), never Twig functions
3. Table names without `cms_` prefix everywhere
4. Primary key is `num`, never `id`
5. Upload fields are arrays — access with `[0].urlPath`
6. Tailwind CSS as primary styling, custom CSS scoped with BEM when needed
7. Twig concatenation uses `~` operator: `'value=' ~ variable`
8. `enlace` (link) fields already include slashes
