Hi everybody!!
I'm trying to do this:
indg=IndicatorGroups()
indg.name=group
session.save(indg)
ind=Indicators()
ind.code=code
ind.name=indicator
ind.idindicatorgroup=indg
session.save(ind)
session.flush()
but I have this error:

u can use the timephase-separation, i.e. declare vs runtime;
i.e. use global scope in for B in A, but use runtime scope for A in B.

Hi there,
We have a pretty large project by now and we run into import loops. So
I decided to restructure the code, and I hoped some people with more
experience can comment on this.
The basic problem is this:
We have the database object code, mappers and tables neatly organized
in one module

Dear all,
I'm quite confused to use Session like a global statement through
different parts of a web program. The directory structure is the
following:
WebML/
+- webml.py (main program)
+- globals.py
+- managers/
+- __init__.py
+- users_schema.py
By the way, on a larger database, drop_all() runs into an endless
loop. However, I have no small script to reproduce this yet.

One of the reasons that Query.select() is deprecated is that the way it was
named led to this kind of confusion.
The Query() class is used for ORM operations, and when it's used as mapped
against a table, it's going to give you all the columns from the table by
default. There are ways of defining
Thanks. I have it working in SQL expression language, using text in

move it over to using the select(), join(), etc. functions that are
