databasemodels 1.5.0

Python class decorator that creates a database representation of a class and vice versa, a lightweight ORM.

Database Models

Python class decorator that creates a database representation of a class and vice versa, a lightweight ORM. setup.py provided for installation, uses psycopg 3 rather than 2 for the better context manager support and type hinting.

Recommended Import Setup

import databasemodels as dbm
from databasemodels.datatypes import *

This allows you to use bare datatypes such as INTEGER, or complex datatypes such as PrimaryKey.

Features

All basic types and pseudo-types implemented are all capital, whereas type modifiers and constructed types like enums are capital camel case.

Currently, implemented types/pseudo-types include:

EnumType
INTEGER
SERIAL
REAL
TEXT
TIMESTAMP
TIMESTAMP_WITH_TIMEZONE
DATE
TIME
BOOL
VARCHAR
CHAR
NUMERIC

Currently, implemented constraints include:

ForeignKey
PrimaryKey
Unique
NotNull

Models have a "mutate" context manager which allows you to modify the model safely while reverting the changes if an error is raised.

Planned Features

• Interval type
• Additional SQL parameter to createTable
• Full documentation across all the module
• Implementation of all types listed here.
• Higher unittest coverage
• Higher customizability with table creation and other database operations
