SQLAlchemy Error Fix:
- Add .unique() when using joinedload(Company.vendors)
- When eagerly loading collection relationships with joinedload, SQLAlchemy can return duplicate rows
- The unique() method deduplicates results and is required for joined collection loads
Error was:
InvalidRequestError: The unique() method must be invoked on this Result, as it contains results that include joined eager loads against collections
This is a standard SQLAlchemy pattern for handling one-to-many relationships with eager loading.
