didactic-pydantic
Bidirectional adapter between pydantic.BaseModel and dx.Model.
Contributes didactic.pydantic to the namespace package.
Install
pip install didactic-pydantic
The package depends on didactic and pydantic>=2.10.
Quickstart
from_pydantic converts a pydantic.BaseModel subclass into a
dx.Model subclass:
from pydantic import BaseModel, Field
from didactic.pydantic import from_pydantic
class PydUser(BaseModel):
id: str
email: str = Field(description="primary contact")
User = from_pydantic(PydUser)
Field annotations, defaults, factories, aliases, descriptions,
examples, and the deprecated flag carry across.
Annotated[T, ...] constraint metadata flows through unchanged, so
annotated-types primitives (Ge, Le, ...) continue to produce
axioms on the didactic side.
Custom Pydantic validators (@field_validator, @model_validator),
@computed_field, and discriminated unions are not translated; the
Pydantic interop guide
lists the didactic-side replacements.
to_pydantic is the inverse direction:
import didactic.api as dx
from didactic.pydantic import to_pydantic
class User(dx.Model):
id: str
email: str = dx.field(description="primary contact")
PydUser = to_pydantic(User)
Use to_pydantic to expose a dx.Model to FastAPI, OpenAPI
generators, or any other Pydantic-shaped tool. The conversion is
cached, so repeated calls with the same input return the same
Pydantic class.
