* Add docs for [Schema Extra - Example](https://fastapi.tiangolo.com/tutorial/schema-extra-example/). PR [#1185](https://github.com/tiangolo/fastapi/pull/1185).

## 0.53.1 (2020-03-29)

* Fix included example after translations refactor. PR [#1182](https://github.com/tiangolo/fastapi/pull/1182).

    fields `username` and `password`.

    All the initialization parameters are extracted from the request.

    Read more about it in the
    [FastAPI docs for Simple OAuth2 with Password and Bearer](https://fastapi.tiangolo.com/tutorial/security/simple-oauth2/).

    ## Example

    ```python
    from typing import Annotated

    from fastapi import Depends, FastAPI
    from fastapi.security import OAuth2PasswordRequestForm

   * | `http://host/?`                   | `""`                   |
   * | `http://host/?a=apple&k=key+lime` | `"a=apple&k=key+lime"` |
   * | `http://host/?a=apple&a=apricot`  | `"a=apple&a=apricot"`  |
   * | `http://host/?a=apple&b`          | `"a=apple&b"`          |

You just saw the main place to declare type hints. As function parameters.

This is also the main place you would use them with **FastAPI**.

### Simple types { #simple-types }

You can declare all the standard Python types, not only `str`.

You can use, for example:

* `int`
* `float`
* `bool`
* `bytes`

{* ../../docs_src/python_types/tutorial005_py310.py hl[1] *}

        .Builder()
        .add("*.example.com", certA1Sha256Pin)
        .add("a.example.com", certB1Sha256Pin)
        .add("b.example.com", certC1Sha256Pin)
        .build()

    val expectedPins =
      listOf(
        Pin("*.example.com", certA1Sha256Pin),
        Pin("a.example.com", certB1Sha256Pin),
      )
    assertThat(certificatePinner.findMatchingPins("a.example.com")).isEqualTo(expectedPins)
  }

1. Here we use the `--workers` command line option to set the number of workers to 4.

Here are some examples of when that could make sense:

#### A Simple App { #a-simple-app }

You could want a process manager in the container if your application is **simple enough** that can run it on a **single server**, not a cluster.

#### Docker Compose { #docker-compose }

* do we need a dictionary for our applications like Apple does. We could easily hook into this and this is the model we need to follow. Following the model of apple applications the dictionary is what the REST URI should attach to. Not creating custom logic in the resource code.
* how many of our REST services do not map directory to a method in the application interface?

At the highest level, Gradle's execution model is quite simple:

Below is the protocol in some more detail:

1. The client looks for a compatible idle daemon. If there isn't one, it starts a new daemon.
2. The client connects to the idle daemon and sends it a request to do some work. If the daemon is no longer running, the client starts again.
