creyPY

My collection of Python and FastAPI shortcuts etc.

Installation

pip install creyPY -U

Versioning

This library uses Semantic Versioning.

FastAPI

This library installes fastapi and pydantic, as well as sqlalchemy for you. It also provides a sqlalchemy base class and companion pydantic schemas. Also there are some helper functions for FastAPI in creyPY.fastapi.app like generate_unique_id to generate unique operation IDs for the OpenAPI schema to work with code generators.

Database connection

The creyPY.fastapi.db module provides a Session class that can be used as a context manager to connect to a database. It exposes the SQLALCHEMY_DATABASE_URL variable for you to use. It uses the following environment variables:

• POSTGRES_HOST: The host of the database
• POSTGRES_PORT: The port of the database
• POSTGRES_USER: The user of the database
• POSTGRES_PASSWORD: The password of the database
• POSTGRES_DB: The database name

Currently only PostgreSQL is supported. It creates a sync session, it is planned to add async support in the future. You can use this like this:

from creyPY.fastapi.db.session import get_db

async def test_endpoint(
    db: Session = Depends(get_db),
) -> Any:
    pass

Constants

The constants module contains a few enums that I use in my projects. The best way to understand this library is to look at the code (it's not that much). However for simplicity, here is a brief overview:

• LanguageEnum: Contains all languages according to ISO 639
• CountryEnum: Contains all countries according to ISO 3166
• CurrencyEnum: Contains all accepted stripe currencies (Commented out are the Zero-decimal currencies, to avoid custom implementation)
• StripeStatus: Contains all stripe payment statuses
• GroupMode: Contains time group modes (e.g. day, week, month, year)

Usage example

from creyPY.const import LanguageEnum

print(LanguageEnum.EN) # Output: LanguageEnum.EN
print(LanguageEnum.EN.value) # Output: English

TODO

• Add async support for database connection
• Add version without postgresql dependency
