Option: emit_pydantic_models

By default, sqlc-gen-python will emit dataclasses for the models. If you prefer to use pydantic models, you can enable this option.

with emit_pydantic_models

from pydantic import BaseModel

class Author(pydantic.BaseModel):
    id: int
    name: str

without emit_pydantic_models

import dataclasses

@dataclasses.dataclass()
class Author:
    id: int
    name: str

Option: output_models_suffix

By default, generated models and query-specific types keep their standard names (Author, GetAuthorRow, CreateAuthorParams, etc). If you want to avoid naming collisions with existing application types, you can add a suffix.

with output_models_suffix: DTO

class AuthorDTO:
    ...

class CreateAuthorParamsDTO:
    ...

Option: emit_str_enum

enum.StrEnum was introduce in Python 3.11.

enum.StrEnum is a subclass of str that is also a subclass of Enum. This allows for the use of Enum values as strings, compared to strings, or compared to other enum.StrEnum types.

This is convenient for type checking and validation, as well as for serialization and deserialization.

By default, sqlc-gen-python will emit (str, enum.Enum) for the enum classes. If you prefer to use enum.StrEnum, you can enable this option.

with emit_str_enum

class Status(enum.StrEnum):
    """Venues can be either open or closed"""
    OPEN = "op!en"
    CLOSED = "clo@sed"

without emit_str_enum (current behavior)

class Status(str, enum.Enum):
    """Venues can be either open or closed"""
    OPEN = "op!en"
    CLOSED = "clo@sed"
