Quick Fix: Replace .dict() with .model_dump() as the recommended way to convert Pydantic models to dictionaries. Ensure to specify the mode parameter when converting non-JSON serializable objects.
The Problem:
When using the .dict() method on a Pydantic model in FastAPI, a deprecation warning is displayed. Despite upgrading pydantic and VScode, the issue persists.
The Solutions:
Solution 1: Deprecation warning solved using pydantic Model methods
To resolve the deprecation warning related to model.dict(), Pydantic introduces new methods for serialization. The migration guide recommends using .model_dump() instead of .dict(). This method allows for more customization and options when converting models to dictionaries. Alternatively, one can also use dict(model) to obtain a dictionary of raw field values. However, this method does not perform recursive conversion of nested models into dictionaries, which .model_dump() does.
