Kevin Rosales 38d86531e8 feat: Add comprehensive A76 modules with database relationships
 New Features:
- Company module: Single company management with comprehensive business info
- Client & Provider module: Manages clients/providers with address/program relationships
- GParts module: Parts/components management for SCAII, SCAF, and WINSAAI systems
- GClass module: Class classifications for SCAII and SCAF with tariff information

🔗 Database Relationships:
- GPart ↔ GClass: Composite key relationship (client_key, part_class ↔ class_code)
- GPart → Country: Foreign key to public.countries (country_of_origin)
- GPart → CurrencyType: Foreign key to public.currency_types (currency_key)
- GClass → MaterialType: Foreign key to public.material_types (material_key)

🏗️ Architecture:
- Modular design with models, DTOs, services, and routes for each entity
- English field names with composite primary keys where applicable
- Comprehensive CRUD operations with specialized search endpoints
- SQLAlchemy relationships with proper foreign key constraints
- Type-safe DTOs with Pydantic validation

📝 Documentation:
- RELATIONSHIPS.md: Complete documentation of database relationships
- Detailed type hints and comprehensive service methods
- Consistent patterns across all modules for maintainability

Relaciones entre Modelos A76

Resumen de Relaciones Establecidas

GPart (Tabla: gparts)

El modelo GPart representa las partes/componentes en los sistemas SCAII, SCAF y WINSAAI.

Relaciones:

  1. Con Country (public.countries)

    • Campo: country_of_origincountries.m3_key
    • Relación: Many-to-One
    • Propósito: País de origen de la parte
  2. Con CurrencyType (public.currency_types)

    • Campo: currency_keycurrency_types.code
    • Relación: Many-to-One
    • Propósito: Tipo de moneda para el costo unitario
  3. Con GClass (gclasses)

    • Campos: (client_key, part_class)(client_key, class_code)
    • Relación: Many-to-One (usando primaryjoin complejo)
    • Propósito: Clasificación de la parte
    • Atributo: part_class_info

GClass (Tabla: gclasses)

El modelo GClass representa las clases de clasificación en sistemas SCAII y SCAF.

Relaciones:

  1. Con MaterialType (public.material_types)

    • Campo: material_keymaterial_types.key
    • Relación: Many-to-One
    • Propósito: Tipo de material de la clase
  2. Con GPart (gparts)

    • Campos: (client_key, class_code)(client_key, part_class)
    • Relación: One-to-Many (inversa de la relación en GPart)
    • Propósito: Partes que pertenecen a esta clase
    • Atributo: parts

Esquema de Relaciones

GPart
├── country (Country)              # País de origen
├── currency (CurrencyType)        # Tipo de moneda
└── part_class_info (GClass)       # Información de clasificación
    └── material_type (MaterialType) # Tipo de material

GClass
├── material_type (MaterialType)   # Tipo de material
└── parts (List[GPart])           # Partes que usan esta clase

Uso de las Relaciones

En consultas:

# Obtener una parte con su información completa
part = session.query(GPart).options(
    joinedload(GPart.country),
    joinedload(GPart.currency),
    joinedload(GPart.part_class_info).joinedload(GClass.material_type)
).filter(
    GPart.client_key == 1,
    GPart.part_number == "PART001"
).first()

# Acceder a los datos relacionados
print(f"País: {part.country.description_es}")
print(f"Moneda: {part.currency.currency_name}")
print(f"Clase: {part.part_class_info.description_spanish}")
print(f"Material: {part.part_class_info.material_type.description}")

En DTOs:

Los DTOs pueden incluir información relacionada:

class PartDetailResponseDTO(BaseModel):
    client_key: int
    part_number: str
    description_spanish: Optional[str]
    country_name: Optional[str] = None
    currency_name: Optional[str] = None
    class_description: Optional[str] = None
    material_type: Optional[str] = None

Consideraciones Técnicas

  1. Composite Foreign Keys: La relación entre GPart y GClass usa claves foráneas compuestas que requieren primaryjoin personalizado.

  2. Viewonly Relationships: Algunas relaciones están marcadas como viewonly=True para evitar problemas de escritura accidental.

  3. Lazy Loading: Por defecto, las relaciones usan lazy loading. Para consultas que necesiten datos relacionados, usar joinedload o selectinload.

  4. Type Hints: Se usan TYPE_CHECKING imports para evitar import circulares mientras se mantienen los type hints.

Futuras Relaciones

Potenciales relaciones adicionales que se pueden agregar:

  1. Con Sectors (public.sectors) - para clasificación sectorial
  2. Con Transport Types (public.transport_types) - para modo de transporte
  3. Con Customs Sections (public.customs_sections) - para sección aduanera
  4. Relaciones con tablas subsidiarias como SPartes, QPartes, etc.
