-## Problema 1: Pantalla Blanca en Water Meters y Consumo
+## 2026-02-09: Organismos Operadores + Historico de Tomas + Documentacion
-### Síntoma
+### Resumen
-Al navegar a "Water Meters" o "Consumo", la página se quedaba en blanco.
+Implementacion completa del sistema de 3 niveles de roles (ADMIN → ORGANISMO_OPERADOR → OPERATOR), nueva pagina Historico de Tomas, y actualizacion de toda la documentacion.
-### Causa
+### Nuevas Funcionalidades
 PostgreSQL devuelve valores DECIMAL como strings (ej: `"300.0000"`). El código llamaba `.toFixed()` directamente sobre estos strings, pero `.toFixed()` es un método de números, no de strings.
-### Solución
+**Rol ORGANISMO_OPERADOR (8 fases completas)**
-Convertir los valores a número con `Number()` antes de llamar `.toFixed()`.
+- Nueva tabla `organismos_operadores` con migracion SQL

-## Problema 2: Modal de Carga Masiva se Cerraba sin Mostrar Resultados
+## 2026-01-23: Fix pantalla blanca y carga masiva
-### Síntoma
+### Resumen
-Al subir un archivo Excel para carga masiva, el modal se cerraba inmediatamente sin mostrar cuántos registros se insertaron o qué errores hubo.
+Correccion de errores criticos que causaban pantalla blanca y mejoras en el sistema de carga masiva.
-### Causa
+### Problema 1: Pantalla Blanca en Water Meters y Consumo
 El callback `onSuccess` cerraba el modal automáticamente:
 ```typescript
 onSuccess={() => {
  m.loadMeters();
  setShowBulkUpload(false);  // ← Cerraba antes de ver resultados
 }}
 ```
-### Solución
+**Sintoma:** Al navegar a "Water Meters" o "Consumo", la pagina se quedaba en blanco.
 Separar la recarga de datos del cierre del modal. Ahora el modal solo se cierra cuando el usuario hace clic en "Cerrar".
-### Archivo Modificado
+**Causa:** PostgreSQL devuelve valores DECIMAL como strings (ej: `"300.0000"`). El codigo llamaba `.toFixed()` directamente sobre estos strings.
-**`src/pages/meters/MeterPage.tsx` (líneas 332-340)**
+**Solucion:** Convertir a numero con `Number()` antes de `.toFixed()`.
 ```typescript
 // ANTES:
 <MetersBulkUploadModal
  onClose={() => setShowBulkUpload(false)}
  onSuccess={() => {
    m.loadMeters();
    setShowBulkUpload(false);
  }}
 />
-// DESPUÉS:
+**Archivos:**
-<MetersBulkUploadModal
+- `src/pages/meters/MetersTable.tsx:75`
-  onClose={() => {
+- `src/pages/consumption/ConsumptionPage.tsx:133, 213, 432`
    m.loadMeters();
    setShowBulkUpload(false);
  }}
  onSuccess={() => {
    m.loadMeters();
  }}
 />
 ```

+### Problema 2: Modal de Carga Masiva se Cerraba sin Resultados
-## Problema 3: Error de Fecha Inválida en Carga Masiva
+**Sintoma:** El modal se cerraba automaticamente despues de la carga sin mostrar resultados.
-### Síntoma
+**Causa:** El callback `onSuccess` cerraba el modal automaticamente.
 Al subir medidores, aparecía el error:
 ```
 Fila X: invalid input syntax for type date: "Installed"
 ```
-### Causa
+**Solucion:** Separar recarga de datos (`onSuccess`) del cierre del modal (`onClose`).
 El archivo Excel tenía columnas con valores como "Installed" o "New_LoRa" que el sistema interpretaba como fechas porque no estaban mapeadas correctamente.
-### Solución
+**Archivo:** `src/pages/meters/MeterPage.tsx:332-340`
 1. **Validar fechas**: Verificar que `installation_date` sea realmente una fecha válida antes de usarla.
 2. **Más mapeos de columnas**: Agregar mapeos para columnas comunes como `device_status`, `device_name`, etc.
 3. **Normalizar status**: Convertir valores como "Installed", "New_LoRa" a "ACTIVE".
-### Archivo Modificado
+### Problema 3: Error de Fecha Invalida en Carga Masiva
-**`water-api/src/services/bulk-upload.service.ts`**
+**Sintoma:** Error `invalid input syntax for type date: "Installed"` al subir medidores.
-Validación de fechas (líneas 183-195):
+**Causa:** Columnas con valores como "Installed" o "New_LoRa" se interpretaban como fechas.
 ```typescript
 let installationDate: string | undefined = undefined;
 if (row.installation_date) {
  const dateStr = String(row.installation_date).trim();
  if (/^\d{4}[-/]\d{1,2}[-/]\d{1,2}/.test(dateStr) || /^\d{1,2}[-/]\d{1,2}[-/]\d{2,4}/.test(dateStr)) {
    const parsed = new Date(dateStr);
    if (!isNaN(parsed.getTime())) {
      installationDate = parsed.toISOString().split('T')[0];
    }
  }
 }
 ```
-Mapeos de columnas adicionales (líneas 65-90):
+**Solucion:**
-```typescript
+1. Validar formato de fecha con regex antes de usarla
-const mappings: Record<string, string> = {
+2. Agregar mapeos de columnas comunes (`device_s/n` → `serial_number`, etc.)
-  // Serial number
+3. Normalizar status ("Installed" → ACTIVE, "New_LoRa" → ACTIVE, etc.)
  'device_s/n': 'serial_number',
  'device_sn': 'serial_number',
  // Name
  'device_name': 'name',
  'meter_name': 'name',
  // Status
  'device_status': 'status',
  // ... más mapeos
 };
 ```
-Normalización de status (líneas 210-225):
+**Archivo:** `water-api/src/services/bulk-upload.service.ts`
 ```typescript
 const statusMappings: Record<string, string> = {
  'INSTALLED': 'ACTIVE',
  'NEW_LORA': 'ACTIVE',
  'NEW': 'ACTIVE',
  'ENABLED': 'ACTIVE',
  'DISABLED': 'INACTIVE',
  // ...
 };
 ```

 ## Autenticacion
-### Flujo de Login
+El sistema usa **JWT con refresh tokens**:
-1. Usuario ingresa credenciales
+1. El usuario envia email/password a `POST /api/auth/login`
-2. Validacion del checkbox "No soy un robot"
+2. El backend valida credenciales con bcrypt y genera:
-3. Token almacenado en `localStorage` (`grh_auth`)
+   - **Access token** (15 minutos)
-4. Redireccion al Dashboard
+   - **Refresh token** (7 dias)
 3. Los tokens se almacenan en `localStorage`
 4. El cliente HTTP envia el access token en `Authorization: Bearer <token>`
 5. Al expirar, el cliente automaticamente llama a `POST /api/auth/refresh`
-### Almacenamiento
+### Roles y permisos (Jerarquia de 3 niveles)
-
+| Rol | Descripcion | Scope |
-```javascript
+|-----|-------------|-------|
-// localStorage keys
+| `ADMIN` | Acceso completo al sistema | Ve todos los datos |
-grh_auth: { token: string, ts: number }
+| `ORGANISMO_OPERADOR` | Gestiona proyectos de su organismo | Ve datos de proyectos de su organismo |

 # Plan: Agregar Rol ORGANISMOS_OPERADORES
 ## Resumen
 Agregar un nuevo rol "ORGANISMOS_OPERADORES" que:
 - Se ubica entre ADMIN y OPERATOR en la jerarquía
 - Permite asignar **múltiples proyectos** a un usuario (a diferencia de OPERATOR que solo tiene uno)
 - Puede ver datos de todos sus proyectos asignados
 ---
 ## Fase 1: Base de Datos
 ### 1.1 Crear migración SQL
 **Archivo nuevo:** `water-api/sql/add_organismos_operadores_role.sql`
 ```sql
 -- Agregar nuevo valor al enum role_name
 ALTER TYPE role_name ADD VALUE 'ORGANISMOS_OPERADORES' AFTER 'ADMIN';
 -- Crear tabla user_projects para relación muchos-a-muchos
 CREATE TABLE user_projects (
    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
    user_id UUID NOT NULL REFERENCES users(id) ON DELETE CASCADE,
    project_id UUID NOT NULL REFERENCES projects(id) ON DELETE CASCADE,
    created_at TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT CURRENT_TIMESTAMP,
    UNIQUE(user_id, project_id)
 );
 CREATE INDEX idx_user_projects_user_id ON user_projects(user_id);
 CREATE INDEX idx_user_projects_project_id ON user_projects(project_id);
 -- Insertar el nuevo rol con permisos
 INSERT INTO roles (name, description, permissions) VALUES (
    'ORGANISMOS_OPERADORES',
    'Organismos Operadores - gestiona múltiples proyectos asignados',
    '{
        "users": {"create": false, "read": true, "update": false, "delete": false},
        "projects": {"create": false, "read": true, "update": true, "delete": false},
        "devices": {"create": true, "read": true, "update": true, "delete": false},
        "meters": {"create": true, "read": true, "update": true, "delete": false},
        "readings": {"create": true, "read": true, "update": false, "delete": false},
        "settings": {"create": false, "read": true, "update": false, "delete": false},
        "reports": {"create": true, "read": true, "export": true}
    }'::JSONB
 );
 ```
 ---
 ## Fase 2: Backend
 ### 2.1 Actualizar validador de roles
 **Archivo:** `water-api/src/validators/role.validator.ts`
 - Línea 7: Agregar 'ORGANISMOS_OPERADORES' al enum
 ```typescript
 export const RoleNameEnum = z.enum(['ADMIN', 'ORGANISMOS_OPERADORES', 'OPERATOR', 'VIEWER']);
 ```
 ### 2.2 Actualizar tipos
 **Archivo:** `water-api/src/types/index.ts`
 - Agregar `projectIds?: string[]` a `JwtPayload`
 - Agregar `project_ids?: string[]` a `User` y `UserPublic`
 ### 2.3 Actualizar servicio de usuarios
 **Archivo:** `water-api/src/services/user.service.ts`
 - Agregar funciones `getUserProjects(userId)` y `setUserProjects(userId, projectIds[])`
 - Modificar `create()` para manejar `project_ids` cuando rol es ORGANISMOS_OPERADORES
 - Modificar `update()` igual
 - Modificar `getById()` y `getAll()` para incluir project_ids en respuesta
 ### 2.4 Actualizar servicio de autenticación
 **Archivo:** `water-api/src/services/auth.service.ts`
 - En `login()`: si rol es ORGANISMOS_OPERADORES, consultar `user_projects` y agregar array al JWT
 - En `refresh()`: mismo cambio
 - En `getMe()`: retornar `project_ids` array
 ### 2.5 Actualizar middleware de autenticación
 **Archivo:** `water-api/src/middleware/auth.middleware.ts`
 - Extraer `projectIds` del JWT y adjuntar a `req.user`
 ### 2.6 Actualizar validador de usuarios
 **Archivo:** `water-api/src/validators/user.validator.ts`
 - Agregar `project_ids: z.array(z.string().uuid()).optional()` a schemas
 ---
 ## Fase 3: Frontend
 ### 3.1 Actualizar API de autenticación
 **Archivo:** `src/api/auth.ts`
 - Agregar `projectIds?: string[]` a `JwtPayload` y `AuthUser`
 - Agregar función `getCurrentUserProjectIds(): string[] | null`
 - Agregar función `isOrganismosOperadores(): boolean`
 ### 3.2 Actualizar API de usuarios
 **Archivo:** `src/api/users.ts`
 - Agregar `project_ids?: string[]` a interfaces `User`, `CreateUserInput`, `UpdateUserInput`
 ### 3.3 Actualizar UsersPage
 **Archivo:** `src/pages/UsersPage.tsx`
 - Agregar `projectIds?: string[]` a interfaces
 - Agregar componente de selección múltiple de proyectos para ORGANISMOS_OPERADORES
 - Mantener selector único para OPERATOR
 - Validar que se seleccione al menos un proyecto para ORGANISMOS_OPERADORES
 ### 3.4 Actualizar Sidebar
 **Archivo:** `src/components/layout/Sidebar.tsx`
 - Agregar `isOrganismosOperadores` check
 - ORGANISMOS_OPERADORES puede ver: Dashboard, Proyectos, Medidores, Concentradores, Consumo, Analytics
 - ORGANISMOS_OPERADORES NO puede ver: Users Management, Conectores, Auditoría
 ### 3.5 Actualizar páginas de datos
 **Archivos:**
 - `src/pages/meters/useMeters.ts`
 - `src/pages/consumption/ConsumptionPage.tsx`
 - `src/pages/projects/ProjectsPage.tsx`
 Cambios en cada archivo:
 - Importar `getCurrentUserProjectIds`
 - Filtrar proyectos visibles usando array de IDs
 - Permitir cambiar entre proyectos asignados
 ---
 ## Orden de Implementación
 1. **SQL Migration** - Crear tabla y enum
 2. **Backend Types** - Actualizar tipos base
 3. **Backend Validators** - Actualizar validaciones
 4. **Backend Services** - user.service.ts, auth.service.ts
 5. **Backend Middleware** - auth.middleware.ts
 6. **Frontend Auth API** - src/api/auth.ts
 7. **Frontend Users API** - src/api/users.ts
 8. **Frontend UsersPage** - Multi-select UI
 9. **Frontend Sidebar** - Visibilidad de menús
 10. **Frontend Data Pages** - Filtrado por proyectos
 ---
 ## Archivos a Modificar
 | Archivo | Cambio |
 |---------|--------|
 | `water-api/sql/add_organismos_operadores_role.sql` | **NUEVO** - Migración |
 | `water-api/src/validators/role.validator.ts` | Agregar enum value |
 | `water-api/src/validators/user.validator.ts` | Agregar project_ids |
 | `water-api/src/types/index.ts` | Agregar projectIds a tipos |
 | `water-api/src/services/user.service.ts` | Funciones multi-proyecto |
 | `water-api/src/services/auth.service.ts` | ProjectIds en JWT |
 | `water-api/src/middleware/auth.middleware.ts` | Extraer projectIds |
 | `src/api/auth.ts` | Funciones helper |
 | `src/api/users.ts` | Actualizar interfaces |
 | `src/pages/UsersPage.tsx` | Multi-select UI |
 | `src/components/layout/Sidebar.tsx` | Visibilidad menús |
 | `src/pages/meters/useMeters.ts` | Filtrado multi-proyecto |
 | `src/pages/consumption/ConsumptionPage.tsx` | Filtrado multi-proyecto |
 | `src/pages/projects/ProjectsPage.tsx` | Filtrado multi-proyecto |
 ---
 ## Verificación
 1. **Base de datos**: Ejecutar migración y verificar que el rol existe
 2. **Backend**:
   - Crear usuario con rol ORGANISMOS_OPERADORES y múltiples proyectos
   - Verificar que JWT incluye array de projectIds
 3. **Frontend**:
   - Verificar multi-select aparece solo para ORGANISMOS_OPERADORES
   - Verificar que sidebar muestra/oculta elementos correctamente
   - Verificar que páginas de datos filtran por proyectos asignados

Exteban08	da976b9003	Update all documentation for 3-level roles, organismos, and Histórico Reflect current project state across all 8 docs: ADMIN/ORGANISMO_OPERADOR/OPERATOR role hierarchy, scope filtering, organismos_operadores table, Histórico de Tomas page, new SQL migrations, and updated API endpoints with auth requirements. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-09 10:44:16 +00:00
Exteban08	613fb2d787	Add 3-level role permissions, organismos operadores, and Histórico de Tomas page Implements the full ADMIN → ORGANISMO_OPERADOR → OPERATOR permission hierarchy with scope-filtered data access across all backend services. Adds organismos operadores management (ADMIN only) and a new Histórico page for viewing per-meter reading history with chart, consumption stats, and CSV export. Key changes: - Backend: 3-level scope filtering on all services (meters, readings, projects, users) - Backend: Protect GET /meters routes with authenticateToken for role-based filtering - Backend: Pass requestingUser to reading service for scoped meter readings - Frontend: New HistoricoPage with meter selector, AreaChart, paginated table - Frontend: Consumption cards (Actual, Pasado, Diferencial) above date filters - Frontend: Meter search by name, serial, location, CESPT account, cadastral key - Frontend: OrganismosPage, updated Sidebar with 3-level visibility - SQL migrations for organismos_operadores table and FK columns Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-09 10:21:33 +00:00
