hello all,
My tables are giving following error at the time of querying. The tables got
created properly but when i query on some table it is showing error on other
tables.I didnt understand whats the issue here. I am querying on login table
it is giving error on debitnote details tables.
Hi anusha,
The error is unrelated to your Login query because sqlalchemy compiles
the mappers as late as possible. It might help if you put somewhere
in your application code, after you have imported all your entities,
the lines:
from sqlalchemy import orm
orm.compile_mappers()
to catch

Now the specific problem you see is that the ORM uses the declared
ForeignKeys to determine how to join tables for a relation, but on
your Detail table you have two foreign keys back to account and the
ORM doesn't know which one to use.

from sqlalchemy import schema, types, sql, create_engine
metadata = schema.MetaData()
x = schema.Table(

schema.Column('id', types.Integer, primary_key=True),

Unfortunately, fold_equivalents is not a generic solution for me
I have a generative query, where I later add the select_from object.
The query is generative, since the tables involved are not know in
advance.
