OpencodeBase

What it is​

  • A minimal SQLAlchemy declarative base class used as the superclass for ORM model classes.

Public API​

  • class OpencodeBase(DeclarativeBase)
    • Purpose: Provides the SQLAlchemy DeclarativeBase for defining mapped ORM models.

Configuration/Dependencies​

  • Requires sqlalchemy with ORM support:
    • from sqlalchemy.orm import DeclarativeBase

Usage​

from sqlalchemy import Integer, String
from sqlalchemy.orm import Mapped, mapped_column

from naas_abi_core.models.opencode.Base import OpencodeBase

class User(OpencodeBase):
    __tablename__ = "users"

    id: Mapped[int] = mapped_column(Integer, primary_key=True)
    name: Mapped[str] = mapped_column(String)

Caveats​

  • This class only defines the base; it does not configure an engine, session, or metadata handling beyond what DeclarativeBase provides.
