didactic-fastapi
didactic-fastapi adapts dx.Model classes for FastAPI request validation,
response validation, and OpenAPI generation. It adds the didactic.fastapi
module and uses didactic-pydantic at the framework boundary.
Install
pip install didactic-fastapi
The distribution depends on didactic, didactic-pydantic, and
fastapi>=0.115.
Use a Didactic response model
import didactic.api as dx
from didactic.fastapi import as_response, register_validation_handler
from fastapi import FastAPI
class User(dx.Model):
id: str
email: str
app = FastAPI()
register_validation_handler(app)
@app.get("/users/{user_id}", response_model=as_response(User))
def get_user(user_id: str) -> User:
return User(id=user_id, email="ada@example.org")
as_response(User) returns a cached pydantic.BaseModel subclass that mirrors
User. FastAPI uses that class for validation and OpenAPI generation.
Adapter behavior
| Function | Behavior |
|---|---|
as_response(model) |
returns the generated Pydantic class for a response model |
as_request(model) |
returns the same adapter under a request-oriented name |
register_validation_handler(app) |
converts dx.ValidationError raised in a route into a FastAPI-style 422 response |
Models with dx.indexed_by fields retain their cross-field validation. Their
known index cases also appear as conditional constraints in the generated
OpenAPI schema.
