ERAlchemy 0.0.6

Simple entity relation (ER) diagrams generation

ERAlchemy: Simple entity relation (ER) diagrams generation.

It’s now integrated with SQLAlchemy.

It’s also able to generate the ER digram from an existing database.

Quick Start

from eralchemy import draw_er
# Draw from SQLAlchemy base
draw_er(Base, 'erd_from_sqlalchemy.png')

# Draw from database
draw_er("sqlite:///relative/path/to/db.db", 'erd_from_sqlite.png')

Install

ERAlchemy requires GraphViz to generate the graphs. Install graphviz for your system.
