## Patrones Obligatorios
|
|
|
|
### 1. Entity Multi-Tenant
|
|
|
|
```typescript
|
|
// shared/entities/tenant-aware.entity.ts
|
|
import {
|
|
Column,
|
|
CreateDateColumn,
|
|
UpdateDateColumn,
|
|
DeleteDateColumn,
|
|
} from 'typeorm';
|
|
|
|
export abstract class TenantAwareEntity {
|
|
@Column('uuid')
|
|
tenant_id: string;
|
|
|
|
@CreateDateColumn({ type: 'timestamptz' })
|
|
created_at: Date;
|
|
|
|
@UpdateDateColumn({ type: 'timestamptz' })
|
|
updated_at: Date;
|
|
|
|
@DeleteDateColumn({ type: 'timestamptz' })
|
|
deleted_at: Date;
|
|
}
|
|
|
|
// Uso en entity
|
|
@Entity('clients', { schema: 'crm' })
|
|
export class Client extends TenantAwareEntity {
|
|
@PrimaryGeneratedColumn('uuid')
|
|
id: string;
|
|
|
|
@Column({ length: 255 })

|
|
constructor(protected readonly repository: Repository<T>) {}
|
|
|
|
async findAllByTenant(tenantId: string): Promise<T[]> {
|
|
return this.repository.find({
|
|
where: { tenant_id: tenantId } as any,
|
|
});
|
|
}
|
|
|
|
async findOneByTenant(tenantId: string, id: string): Promise<T | null> {
|
|
return this.repository.findOne({
|
|
where: { id, tenant_id: tenantId } as any,
|
|
});
|
|
}
|
|
|
|
async createForTenant(tenantId: string, dto: any): Promise<T> {
|
|
const entity = this.repository.create({
|
|
...dto,
|
|
tenant_id: tenantId,
|
|
});
|
|
return this.repository.save(entity);
|
|
}

|
|
```
|
|
|
|
### 3. Controller con Tenant

@Controller('crm/clients')
|
|
@UseGuards(JwtAuthGuard, TenantMemberGuard)
|
|
@ApiTags('CRM - Clients')
|
|
export class ClientsController {

|
constructor(private readonly clientService: ClientService) {}
|
|
|
|
@Get()
|
|
@ApiOperation({ summary: 'Listar clientes del tenant' })
|
|
async findAll(
|
|
@CurrentTenant() tenantId: string,
|
|
@Query() query: PaginationDto,
|
|
) {
|
|
return this.clientService.findAllByTenant(tenantId, query);
|
|
}
|
|
|
|
@Post()
|
|
@ApiOperation({ summary: 'Crear cliente' })
|
|
async create(
|
|
@CurrentTenant() tenantId: string,
|
|
@Body() dto: CreateClientDto,
|
|
) {
|
|
return this.clientService.createForTenant(tenantId, dto);
|
|
}
|
|
}
|
|
```
|
|
|
|
### 4. DTO con Validacion
|
|
|
|
```typescript
|
|
// dto/create-client.dto.ts

|
import { IsString, IsOptional, IsEnum, MaxLength } from 'class-validator';
|
|
import { ApiProperty, ApiPropertyOptional } from '@nestjs/swagger';
|
|
|
|
export class CreateClientDto {
|
|
@ApiProperty({ description: 'Nombre del cliente', maxLength: 255 })
|
|
@IsString()
|
|
@MaxLength(255)
|
|
name: string;
|
|
|
|
@ApiPropertyOptional({ description: 'Slug URL-friendly' })
|
|
@IsOptional()
|
|
@IsString()
|
|
@MaxLength(100)
|
|
slug?: string;
|
|
|
|
@ApiPropertyOptional({ enum: ClientType, default: ClientType.COMPANY })
|
|
@IsOptional()

|
|
constructor(private dataSource: DataSource) {}
|
|
|
|
async use(req: Request, res: Response, next: NextFunction) {
|
|
const tenantId = req.user?.tenantId;
|
|
|
|
if (tenantId) {
|
|
// Set para RLS de PostgreSQL
|
|
await this.dataSource.query(
|
|
`SET app.current_tenant = '${tenantId}'`
|
|
);
|
|
|
|
// Agregar al request para uso en controllers

|
|
const request = ctx.switchToHttp().getRequest();
|
|
return request.user?.tenantId;
|
|
},
|
|
);
|
|
|
|
// common/decorators/current-user.decorator.ts
|
|
export const CurrentUser = createParamDecorator(
|
|

|
|
const request = ctx.switchToHttp().getRequest();
|
|
return request.user;
|
|
},
