pyramid_basemodel - a thin, low level SQLAlchemy bindings to pyramid

pyramid_basemodel

pyramid_basemodel is a thin, low level package that provides an SQLAlchemy declarative Base and a thread local scoped Session that can be used by different packages whilst only needing to be bound to a db engine once.

Usage

You can use these as base classes for declarative model definitions, e.g.:

from pyramid_basemodel import Base, BaseMixin, Session, save

class MyModel(Base, BaseMixin):
    """Example model class."""

    @classmethod
    def do_foo(cls):
        instance = Session.query(cls).first()
        save(instance)

You can then bind these to the sqlalchemy.url in your paster .ini config by importing your model and this package, e.g.:

# for example in yourapp.__init__.py
import mymodel

def main(global_config, **settings):
    config = Configurator(settings=settings)
    config.include('pyramid_basemodel')
    config.include('pyramid_tm')
    return config.make_wsgi_app()

Or if this is all too much voodoo, you can just use the bind_engine function:

.. code-block:: python

from pyramid_basemodel import bind_engine from mypackage import mymodel

# assuming engine is a bound SQLAlchemy engine. bind_engine(engine)

Note that the Session is designed to be used in tandem with [pyramid_tm][]. If you don’t include pyramid_tm, you’ll need to take care of committing transactions yourself.

Tests

To run the tests use:

py.test -v --cov pyramid_basemodel tests/
