didactic-fastapi
FastAPI integration for dx.Model types.
Contributes didactic.fastapi to the namespace package.
Install
pip install didactic-fastapi
The package depends on didactic, didactic-pydantic, and
fastapi>=0.115.
Quickstart
import didactic.api as dx
from fastapi import FastAPI
from didactic.fastapi import as_response, register_validation_handler
class User(dx.Model):
id: str
email: str
app = FastAPI()
register_validation_handler(app)
@app.get("/users/{uid}", response_model=as_response(User))
def get_user(uid: str) -> User:
return User(id=uid, email="ada@example.org")
as_response(model) returns a pydantic.BaseModel subclass
mirroring the input dx.Model. FastAPI uses the result for response
validation and OpenAPI generation. The conversion is cached per input
class.
as_request(model) is a synonym; use whichever name reads naturally
in your route signatures.
register_validation_handler(app) installs an exception handler so
that dx.ValidationError raised inside a route surfaces as a 422
response shaped like FastAPI's own validation errors.
