Hi ,
I am testing sqlalchemy-migrate with a DB revision script that adds a
table to my database. Two questions here, but first system info:
TG2 Framework (tg.devtools 2.0.2) with
sqlalchemy_migrate-0.5.2-py2.6.egg
MySQL 5.1.41
sqlalchemy V0.5.1
OS X 10.6.4
1) How do I use DeclarativeBase when d
The most logical place would seem to be the database - create a unique
constraint on the 'name' column, or even make the name column the
primary key rather than the integer ID.

Two part question... I have a table of activity types . I want to
follow a ‘singleton pattern’ (ie. Only one instance of
‘run’,’jump’,’swim’ etc.). I have a get_or_create function on the
class that works as long as programmers using my module call:
session.add( ActivityType.get_or_create(‘fly’))
It worked! Thanks, this helped me a lot.

I'd use column.copy() for this purpose.

Hi guys,
In sqlalchemy 0.6.1, had a TypeError when trying to do:
deepcopy(Column('id', Integer, Sequence('id_seq'), primary_key=True)).
But in 0.5.8 the above code works fine, could some one tell me what
causes this error or how can I fix it?
Thanks in advance.

Thank you so much. I'll make a note of that.

unfortunately Essential SQLA is sorely out of date, save() was moved to add()
around the time of late 0.4 and in 0.6 we've removed the old save().

Hello,
I am learning sqlalchemy and been reading and working through the
examples/tutorials in Copeland's "Essential SQLAlchemy".
I am running sqlalchemy 0.6.1 and python2.5
I am running into a problem when trying to save a session using save.
session.save(newuser)
for example. I get an error say
its not really provided right now, the same way saying query.filter(None) won't
reset any existing WHERE criterion, or join(None) doesn't remove all joins.
This issue has come up before. How is order_by() different ?

Hi :)
Take a look at this sample: http://paste.pocoo.org/show/226056/
The update is performed in the line 42. update() is a query operation :)
See official docs:

Hi,
I'm a bit curious about how to unset an order_by in 0.6.
query.order_by(None) should do it, but in sqlalchemy/orm/query.py in
_no_select_modifiers() the notset value for the _order_by attribute is
False. In turn, the order_by() method doesn't seem to accept False.
What would be a proper way
Hi,
I'm having difficulty understanding how to call/create a session to access a
"class method" of a declaratively defined table/object: essentially my
understanding of how session works in this context is at fault... Clearly,
the @classmethod requires a **session** (and I realise that: "declarat

Ok, thanks. I've done some more digging and find that there *are* some
