djanquiltdb-plugin-postgres-objects
django-postgres-objects declares Postgres functions and views as classes and lets makemigrations manage them. DjanQuiltDB shards a database across schemas and nodes. This library serves as a compatibility layer between them, allowing you to mark declarative functions and views as sharded:
# example/functions.py
from djanquiltdb.decorators import public_function
from postgres_objects import Function
@public_function()
class AllUppercase(Function):
arguments = 'input TEXT'
returns = 'TEXT'
volatility = 'IMMUTABLE'
strict = True
parallel = 'SAFE'
body = """
BEGIN
RETURN UPPER(input);
END;
"""
Install it through DjanQuiltDB’s extra:
pip install djanquiltdb[postgres-objects]
The decorators are importable from djanquiltdb.decorators beside the model ones, as above.
Functions get @public_function, @mirrored_function and @sharded_function; views get @public_view, @mirrored_view and @sharded_view. An unannotated declaration is placed in the public schema, so declarations written for a single-database project keep working once that project is sharded.
Full documentation is at https://djanquiltdb.readthedocs.io/en/latest/plugins/postgres-objects/index.html.
Development
This package is developed in the DjanQuiltDB repository beside djanquiltdb itself. Tests run through tox against the Postgres containers in the repository’s docker-compose.yml; see DOCKER.md at the repository root:
