populous 0.4.0

Populate your database with god-like powers

Populous is a tool for fast and rich data generation. From a description of your schema say how many objects you want, what they should look like, and populous will create them for you!

Current state

The project is in a very early stage and proof-of-concept state. Please be patient, but don’t hesitate to share your thoughts and desires with us in the issues.

Documentation

Sorry, but the documentation is not ready yet :( .

However, if you are very eager to try it, here is what you can do:

• Install populous: pip install populous

• Have a PostgreSQL database at hand

• Find some blueprints (YAML files describing what you want to generate) or create some. This is the tricky part, but you can find some examples in the demo/blueprints/ directory.

• Launch populous with those blueprints: populous run postgres demo/blueprints/*.yml (you can pass your postgres instance either via PG* environment variables or via arguments)

• Gaze at your freshly generated data via psql or any other tool!

Troubleshooting

OSX compilation problems

There’s currently no pre-compiled package for the peloton_bloomfilters library, which is a current requirement for populous. To correctly install it in your environment, you’re going to:

• install gcc (via homebrew, for example),

• install the package using the following flags ARCHFLAGS="-arch x86_64" CC=/usr/bin/gcc.

For example, to install locally:

ARCHFLAGS="-arch x86_64" CC=/usr/bin/gcc pip install peloton_bloomfilters

Or if you want to run the test suite via tox:

ARCHFLAGS="-arch x86_64" CC=/usr/bin/gcc tox
