Hi,
The file is a TG2.1 model file that at one time was working but got
left in an intermediate state when I stopped having time to play with
TG. All that is at the module level are normal SQLAlchemy imports
plus I imported Base from the tutorial model file, a bunch of many-to-
many relation tables:
parts_has_datasheets_table = Table('parts_has_datasheets',
Base.metadata,
Column('parts_id', Integer,
ForeignKey('parts.parts_id'), primary_key=True),
Column('datasheets_id', Integer,
ForeignKey('datasheets.datasheets_id'), primary_key=True))
Then there are 21 classes for tables. It has been several months
since I worked with SQLAlchemy so I have to do some relearning but I
think I see an error in one of the classes that seems to correlate to
the error message. Just seems strange that it would break a query
against a different table in another file.
Thanks
Eric
