## Version 2.0.0

This release commits to a stable 2.0 API. Read the 2.0.0-RC1 changes for advice
on upgrading from 1.x to 2.x.

_2014-06-21_

 *  **API Change**: Use `IOException` in `Callback.onFailure()`. This is
    a source-incompatible change, and is different from OkHttp 2.0.0-RC2 which
    used `Throwable`.
 *  Fix: Fixed a caching bug where we weren't storing rewritten request headers

     *
     * @param <T> the target collection type
     * @param from an artifact collection
     * @param to the target artifact collection
     * @return <code>to</code> collection

        for (Artifact artifact : from) {
            to.add(ArtifactUtils.copyArtifact(artifact));
        }

 * <p>We encourage you to return {@code ListenableFuture} from your methods so that your users can

 * instances:

 * <ul>
 *   <li>If you receive them from an {@code java.util.concurrent.ExecutorService}, convert that

## Import Pydantic's `BaseModel` { #import-pydantics-basemodel }

First, you need to import `BaseModel` from `pydantic`:

{* ../../docs_src/body/tutorial001_py310.py hl[2] *}

## Create your data model { #create-your-data-model }

Then you declare your data model as a class that inherits from `BaseModel`.

Use standard Python types for all the attributes:

{* ../../docs_src/body/tutorial001_py310.py hl[5:9] *}

from fastapi import FastAPI
from fastapi.responses import JSONResponse
from pydantic import BaseModel


class Item(BaseModel):
    id: str
    value: str


class Message(BaseModel):
    message: str


app = FastAPI()


@app.get(
    "/items/{item_id}",
    response_model=Item,
    responses={
        404: {"model": Message, "description": "The item was not found"},
