Hi, has the behavior here

I'm trying that and getting

this is my code, so far:
klass = model.User
def add_user():
obj = klass()

Ah, makes sense.
Thanks.

Hi guys,
I'm somewhat confused about the different lifecycle states of objects
that are backed by the SA ORM.
According to the SA docs (FWIW, I'm on 0.4), an object is in the
Persistent state when it is present in the session and has a record in
the database.
So if I do something like this:

I do use Session.mapper. I recall I switched to it since I was getting
"Parent instance ... is not bound" error with sa.orm.mapper.
I hastily
the change is in r5461, objects like dicts and lists will compare
correctly with no changes. Objects that don't implement __eq__() and
are not None will raise a deprecation warning and use the old dumps()
method. Docs are updated on the site as well as 05Migration.

you're compiling the text() construct against the DefaultDialect, when
it needs to be compiled against the PG dialect in order for the :num
bind param to be converted to PG's desired format, %(num)s.Also im
not 100% sure if PG allows bind params for LIMIT, probably does though.

Hi,
i have this table:
class ZmenaDH(Base):
__tablename__="zmenahost"
id = Column(Integer,primary_key=True)
duvod=Column(String(120))
premiera=Column(Date)
id_solo = Column(Integer, ForeignKey('sola.id'))
solo = relation("Solo", backref=backref('zmenahost', order_by=id,
It seems compile()'ing a query results in the default bindparams not
being used, is this a bug?
Simple test case:
>>> from sqlalchemy import *
>>> engine = create_engine('postgres://uname:[EMAIL PROTECTED]/testdb')
>>> query = text('select * from table limit :num', bindparams=[bindparam('num',

Hi
I've scoured the documentation and i can't find any info on how to
create a column using metadata.
from sqlalchemy import engine

This works to some degree:
