How to discover table properties from SQLAlchemy mapped object
- by ssaboum
Hi,
My point is i have a class mapped with a table, in my case in a declarative way, and i want to "discover" table properties, columns, names, relations, from this class :
engine = create_engine('sqlite:///' + databasePath, echo=True)
# setting up root class for declarative declaration
Base = declarative_base(bind=engine)
class Ship(Base):
__tablename__ = 'ships'
id = Column(Integer, primary_key=True)
name = Column(String(255))
def __init__(self, name):
self.name = name
def __repr__(self):
return "<Ship('%s')>" % (self.name)
So now my goal is from the "Ship" class to get the table columns and their properties from another piece of code. I guess i can deal with it using instrumentation but is there any way provided by the SQLAlchemy API ?
Thank you.
