Corebases

Full power of asyncpg with user friendly api of sqlalchemy.core

Corebases - is async adapter for Sqlalchemy.Core. Interface and code based on encode/databases, but has bit difference. Now supported only asycnpg driver (but It's possible to extend)

Current status - Experimental

Reason for create fork

• https://github.com/encode/databases/issues/403#issue-1016133277

Install

> pip install corebases

Usage

# Create a database instance, and connect to it.
from corebases import database
database = database('postgres://user:pass@localhost:5432')
await database.connect()

# Insert some data.
query = "INSERT INTO HighScores(name, score) VALUES (:name, :score)"
value =  {"name": "Daisy", "score": 92}

with database.transaction() as db:
    await db.execute(query=query, value=value)

# Run a database query.
query = "SELECT * FROM HighScores"
rows = await database.fetch_all(query=query)
print('High Scores:', rows)

await database.disconnect()

Difference between encode/databases

Principal is a bit of difference in interface on transactions:

encode/database:

with database.transaction():
    await database.execute(query=query, value=value)

corebases:

with database.transaction() as db:
    await db.execute(query=query, value=value)

Also, corebases doesn't support methods:

• feach_val
• execute_many

But we can add in the future.
