Hi,

SA can form joins between tables automatically if the tables express
the proper foreign key relationship between each other, and if there is
no ambiguity in that relationship; i.e. table A and table B have only
one ForeignKeyConstraint (or single ForeignKey)
a.join(b).join(c).join(d).join(e).
just do a little experimentation, it'll reveal a lot.

Greetings,
I need to dump a sqlalchemy-mapped object to XML, like it implemented
in pyxslt for SQLObject.
So, the questions are:
1) how to separate columns and properties from the other mapped
object's attributes properly -
I need columns, properties and backrefs (surprised, but backrefs work
the INTEGER column coming out is a bug, i just checked in 2167 for
that. for the SERIAL column i just checked the pg docs and noticed
that youre expecting BIGSERIAL, so I put a little conditional in for
that in rev 2168. you should now get
CREATE TABLE company (
company_id BIGSERIAL NOT
youd have to map it back to the mapper's list of props.
PropertyLoader, which is a certain type of MapperProperty, has a flag
is_backref indicating this.
getattr(class_mapper(someclass).props[attributename], 'is_backref',
False)

Hi:
I'm using SA 2.8. I met a strange error. following is a piece of code:
flight.insert().execute(*(_insdict.values()))
it run without error. but after runing, some data in flight table is wrong,
another is right. So I change the code:
for d in _insdict.itervalues():
never seen this issue before. if it persists, post a full test case to
the list.
