Sqlalchemy have this auto load feature which fetches info about tables by itself. I wanted to use this somehow to generate a string which can be easily  copy/paste to database model definition script. So i started a little project to write auto  model generator for sql alchemy based on auto load feature in sqlalchemy.

The script  is not perfect but it works and save a huge amount of time just codding the models. In fact is was able to setup a 186 table database model in 15minutes with this script.

Well the script helped me a lot and now on when i have to load some new existing database or changes i use it all the time.

The documentation is inside the script i tried to write it so anybody could use it out of the box.

I tested it on 4 schema 200+ tables database and i worked quite good. This script still have to be polished but current functionality is enough for most users.

My script is going to be also a part of django-alchemy project started by my friend Lukasz Balcerzak. You can visit the project site @ http://code.google.com/p/django-alchemy/

I used it with Pylons application and Django with modded sqlalchemy. but it can be basically used in any app which uses sqlalchemy. I did not test it with mysql though,but it should work, just specify mysql as dialect.

You can download this script from sqlalchemy model generator

You may ask why to use sqlalchemy under Django if it already have an ORM ?
It’s very easy the django orm is not always the best choice. When using multiple schemas, or multiple database connection the Django ORM just does not provide such functionality.
SqlAlchemy have this built in so when you’re thinking of using multiple schemas or databases in your django project check out his project. Highly recommended
