perfact-api-base

Base package for PerFact API common infrastructure. Part of the perfact.api.base namespace.

What it provides

Base

Declarative base for all ORM table mappings. Subclasses automatically get:

• id — BigInteger primary key
• modtime — DateTime with timezone, defaults to now()
• author — set from the DB session user via db_username()
• Column names are automatically prefixed with the table name (e.g. a field name on AppUser becomes the DB column appuser_name)
• __tablename__ is derived from the class name in lowercase if not set explicitly

View

Separate declarative base for SQL view definitions. Views are not created as tables during schema generation. Columns must be declared with explicit names matching the view definition.

Re-exports

ForeignKey, relationship, Mapped, mapped_column are re-exported so model packages only need to import from this module.

Usage

from perfact.api.base.model import Base, ForeignKey, Mapped, mapped_column, relationship


class MyEntity(Base):
    name: Mapped[str]
    parent_id: Mapped[int | None] = mapped_column(ForeignKey("myentity.myentity_id"))
