ModelLoader and SAContext

rebecca.sqla creates attribute named “sa” to request.context. is SAContext to load models from ModelLoader registered by config.add_model_loader.

here is example models:

class Person(Base):
    __tablename__ = 'person'
    id = Column(Integer, primary_key=True)
    name = Column(Unicode(255))

and example route:

config.add_route('person', '/person/{person1_id}/{person2_id}')

register model loaders:

config.add_model_loader('person1', Person, [('person1_id', 'id')])
config.add_model_loader('person2', Person, [('person2_id', 'id')])

add_model_loader takes 3 arguments. first is attr name of SAContext, second is a model loaded from ModelLoader and last is mappings that matchdict param to model attribute.

second argument can be dotted name.

in view, context has SAContext named “sa” attribute, that has properties of registered models. ModelLoader s load model with query using matchdict parameters.

def person(context, request):
