This commit refactors numerous Pydantic models to align with the V3 ID Vision standard, ensuring that primary and foreign key fields are represented as clean string IDs in the API. It also introduces and populates the ClassVar in each model to prevent view-only fields and linked objects from being inadvertently written to the database during PATCH/POST operations.
Specifically, this includes:
- Adding to exclude view-derived or joined fields such as , , nested objects (e.g., , ), and convenience fields (e.g., ).
- Adjusting root validators to correctly map string IDs and strip internal integer IDs for API responses.
- Resolving a KeyError by adding to .
These changes are crucial for maintaining data integrity and consistency with the V3 API architecture.
