flake8-pydantic-fields

A flake8 plugin that checks that Pydantic models have default values which are Fields, and that those fields have descriptions. This encourages data documentation.

This package adds the following warnings:

• PF001: A Pydantic field which has no default.
• PF002: A Pydantic field with a default that is not a Field.
• PF002: A Pydantic field which has a Field default with no description.

There are no configuration options at this time.

This package uses heuristics to determine whether a class is a Pydantic model. While this could be accomplished by running the code, that is not in the spirit of static analyzers, and it would be considerably slower.

The heuristics are:

It is not a Pydantic model if:

• The class has no base classes.
• The class is annotated with @dataclass.

It is a Pydantic model if:

• The name of the base class is BaseModel or GenericModel.
• The class contains only annotated assignments.
• The class has at least one method decorated with @validator or @root_validator.
• The class contains an inner Config class.
• The class contains only methods with no arguments other than self. These are assumed to be transformations on a data model.
• The class contains an attribute annotated as a ClassVar.
