Hi there.
I have 2 declarative_base classes: Person and Inquiry. I have created
a relationship in Inquiry with a backref to Person.
When observing the an Inquiry object the person variable correctly
points to Person, however when observing Person objects I always get
an empty list in inquiries
I'm on MySQL and trying to create a type that stores enums as
VARCHAR(255). However, the following code still issues an ENUM() DDL.
What am I doing wrong here?
class StringEnum(types.TypeDecorator):
impl = types.Enum
def __init__(self, *args, **kwargs):
super(StringEnum,
TypeDecorator doesn't affect the decorated type via subclassing, it affects it
via the impl attribute, hence decorates. So you say self.impl =
Enum(...). You don't need to use TypeDecorator here if all you want to do
is create an Enum with default arguments, just subclass Enum directly.

It makes sense to subclass the type directly if I'm not messing with
result or bind values. This works:
class StringEnum(types.Enum):
def __init__(self, *args, **kwargs):
super(StringEnum, self).__init__(*args, native_enum=False,
**kwargs)
self.length = 255
I'm still curious
Hi
I thank you very much for your help. I managed to figure out that my
Inquiries table had no associated types in the actual sqlite database,
so after I changed the person_id field to Numeric, all was well and
done without changes to the code. Perhaps just to be aware of.
As for the Adjacency

its pulling off the types.Enum callable from self.__class__ (which actually
seems unnecessary here, self.impl should be fine), then calling that with the
given arguments. So it should be setting up the native_enum=False part
I have an association object pattern between Person and Item through
PersonItem. Item is subclassed using single-table inheritance into
FooItem and BarItem, with a column named 'foo' on FooItem (although
it's obviously on the same shared table as BarItem).
I'd like to query PersonItem and

I tried setting isolation_level to SERIALIZABLE in my create_engine

However, an strace clearly shows that it is using READ COMMITTED.
Is setting the isolation_level not supported with psycopg2?
