Hi all!
I have following model classes:
Entity = sqlalchemy.ext.declarative.declarative_base(name='Entity')
class Ocean(Entity):
__tablename__ = 'oceans'
id = sqlalchemy.Column(sqlalchemy.Integer, primary_key=True)
name = sqlalchemy.Column(sqlalchemy.String(20), nullable=False)
class Sea(Entity):
__tablename__ = 'seas'
id = sqlalchemy.Column(sqlalchemy.Integer, primary_key=True)
name = sqlalchemy.Column(sqlalchemy.String(20), nullable=False)
ocean_id = sqlalchemy.Column(sqlalchemy.String(20),
sqlalchemy.ForeignKey(Ocean.id))
ocean = sqlalchemy.orm.relation(Ocean, backref='seas')
So instances of Ocean have seas property. The question is, if I have a
function:
def foo(entity_class, collection_property):
# ...
that is called width args entity_class=Ocean,
collection_property='seas' could I anyhow to understand from within
this function that 'seas' is assotiated with Sea class and that
Sea.ocean is used to bind a Sea to the Ocean?
Is it ever possible? Thanks
