ERAlchemy generates Entity Relation (ER) diagram (like the one below) from databases or from SQLAlchemy models.

Example

Quick Start

Install

To install ERAlchemy, just do:

$ pip install eralchemy

ERAlchemy requires GraphViz to generate the graphs.

Use from python

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

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

Use from the command line

$ eralchemy -i sqlite:///relative/path/to/db.db -o erd_from_sqlite.png

Architecture

Thanks to it’s modular architecture, it can be connected to other ORMs/ODMs/OGMs/O*Ms.

Notes

Every feedback is welcome on the GitHub issues.

To run the tests, use : $ py.test.
