i'm doing something wrong.
I've got this two classes (User , Groups) in seperet files, where i've
got to put the relation (relationship)? in both files? or just the one
with the ForeignKey?
Also, is the relationship must be
Hi,
I am trying in the same session to detach an instance from a collection ( one
to many)
flush and commit everything (all is ok) and then attach the removed instance
again. unsuccessfully.
in below code, last assert fails.
I don't understand why I am not able to append m2 to o1.to_many

that worked well, thank you very much for your aid. I'm just having

Hi,
I have a sqlite database A and a MySQL database B which share the same
schema, where I want to synchronize the contents of certain tables in
A with those in B at certain times. Except for the synchronizing step
the contents on A's side don't change, while those on B's side might.

Hello Guys,
Thanks for the info, i did expect that to be the case! I can
understand that the architecture is indeed very different.
As an extension to my question then, which DBMS would you guys
recommend for stability. We have a small embedded platform which has
an unreliable power source.
Ah, that makes a lot more sense now.
Your modified createfunc obviously doesn't account for queries with
tuples of entities (some of which may also not be mapped) but I get
the principle. I will just steer well clear of the memory backend -
any production cache would obviously imply pickling and

Roger Binns has incorporated support for CouchDB into apsw by using
SQLite virtual tables. Although apsw cannot be used directly by
SQLAlchemy (as it is not dbapi compliant), you can pass an apsw
connection to pysqlite connect() and then use that connection as a
SQLAlchemy engine. I did some

I guess at this point you'd need to drop 'SQL' from 'SQLAlchemy' ;-)

I'm having some trouble with using a schema with a many-to-many

Thanks very much for the quick reply. The second suggested worked
nicely. I guess this explains why I was having such a hard time

Maybe I can sneak a second question in here which is to ask why the

Excellent. Thanks for the pointers - I'll investigate further and get back to
you. This is really strange as I do not believe that I changed anything from
the point it all worked, to the point at which it didn't! (I'm sure there
will be something however - there always is..).
