pyramid_basemodel - a thin, low level SQLAlchemy bindings to pyramid
Project description
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.
