What is a pydantic field?
Pydantic models are structures that ingest the data, parse it and make sure it conforms to the fields' constraints defined in it. Let's start with a simple example, where we define a Person class that has two fields without any constraints: first_name and last_name . Just like dataclasses, we use type annotations.
What is Orm_mode in pydantic?
ORM Mode (aka Arbitrary Class Instances)
Pydantic models can be created from arbitrary class instances to support models that map to ORM objects. To do this: The Config property orm_mode must be set to True . The special constructor from_orm must be used to create the model instance.
Is pydantic a serializer?
pydantic can serialise many commonly used types to JSON (e.g. datetime , date or UUID ) which would normally fail with a simple json.
What is the use of pydantic in FastAPI?
Pydantic allows custom data types to be defined or you can extend validation with methods on a model decorated with the validator decorator.
