Hi everyone!
I'm looking for a way to log queries at a higher level than SQL.. That
is, given the class

class DataTest(Base):
id = Column(Integer, primary_key = True)
propb = Column(Boolean)
__tablename__ = t

Hi,
Is there any chance someone can look at ticket 973?

This is quite important to me, hitting the bug with a production app.

i'm answering the arhitectural part of your question.

model into the controller which isnt _bad as such but not appropriate
for any complexier/larger modelling. controllers are about

Hi everyone!
I'm trying to implement data logging with SQLAlchemy.. That is,
whenever someone updates a persisted entity, generate a new record and
then mark the old one as such.
My problem right now is that if I load an entity from the DBMS, modify
it and then try to save it again, I have to

I'm curious why a special twisted server is needed to calculate things
that should live very naturally within the relational database, i.e.
votes, user stats, etc. If calculating these things via SQL is
time consuming, those stats can be calculated on a periodic basis

the cleanest way is to leave the old entity alone and to create a new
one using a copy constructor:
class MyEntity(object):
def new_version(self):
return MyEntity(version = self.version + 1, foo=self.foo,
bar=self.bar)
To force an object from an UPDATE back to an INSERT, which is

Hi !
I am a huge fan of declerative base but now I run into a problem...
Say I have a class that stores files in a database:
Base = decclarative_base()
class Document(Base):
Id = Column(Integer, primary_key=True)
Filename = Column(String(255), Unique =
not sure if this is what youre asking but it sounds like this:

Hi, I am writing an application server using twisted and sqlalchemy.
On the server - database relation I use a pool of threads each with its

The problem is that I have 2 tables (one with products and one with

class DavBaseClass(DeclarativeMeta):
def __init__(self,ClassName,Bases,dict_):
dict_['displayname']=

you might want to use a SELECTFOR UPDATE so that the selected rows
are locked for the duration of that transaction.

Hi,
I'm using 0.5rc1. I have a Employee class which I map to an employee
table. The primary key column is called 'employee_id' for some reasons
having to do with joined table inheritance.
Depending on the application, I want to be able to refer
a .employee_id or .id attribute of the Employee

the ambiguity there is what if you set id to one thing and
employee_id to another. I think one would win and the other not.
I usually do what you have there with a synonym which is designed for
this:
mapper(Employee, table, properties={'id':synonym('employee_id')})

Yes, I understand, thank you for your answer. I was hoping that I could
find something more pythonic to do the table locking - I know that it
isn't quite portable and that's why there isn't something more code
oriented, but I didn't want to get to issue a LOCK table for this.
Thanks.

I have been investigating some more and solved the issue
by changing the unbound Unicode to UnicodeText
I am using SA 0.5r1 and mysql 5.x
the unbound Unicode worked with 0.4, I had to upgrade to 0.5 for some
other stuff I used and this confused me.
Nevertheless the Fields defined in the
