hello all! i think this is a quick question: is there a way to get the
referencing table and column from a given foreign key column, rather
then list(col.impl.parent_token.expression.foreign_keys)[0] ?
You can call the .foreign_keys accessor straight off the mapped attribute:
B.a_id.foreign_keys
set([ForeignKey('a.id')])
in relational DBs there is of course no the referencing table because
a column can be referenced, or reference, multiple constraints / columns
/ tables.
best regards,
richard.
