# Deployment { #deployment }

Deploying a **FastAPI** application is relatively easy.

## What Does Deployment Mean { #what-does-deployment-mean }

To **deploy** an application means to perform the necessary steps to make it **available to the users**.

# Развёртывание { #deployment }

Развернуть приложение **FastAPI** довольно просто.

## Что означает развёртывание { #what-does-deployment-mean }

Термин **развёртывание** (приложения) означает выполнение необходимых шагов, чтобы сделать приложение **доступным для пользователей**.

# Deployment { #deployment }

Das Deployment einer **FastAPI**-Anwendung ist relativ einfach.

## Was bedeutet Deployment { #what-does-deployment-mean }

<abbr title="Bereitstellen der Anwendung">**Deployment**</abbr> bedeutet, die notwendigen Schritte durchzuführen, um die Anwendung **für die Endbenutzer verfügbar** zu machen.

It would also mean that if you get data from the `Request` object directly (for example, read the body) it won't be validated, converted or documented (with OpenAPI, for the automatic API user interface) by FastAPI.

This is similar to the 200 HTTP status codes (from 200 to 299). Those "200" status codes mean that somehow there was a "success" in the request.

The status codes in the 400 range mean that there was an error from the client.

Remember all those **"404 Not Found"** errors (and jokes)?

## Use `HTTPException` { #use-httpexception }

# Implantação { #deployment }

## O que significa Implantação { #what-does-deployment-mean }

		default:
			// This is where we'd set it to -1 (at least
			// if body != NoBody) to mean unknown, but
			// that broke people during the Go 1.8 testing
			// period. People depend on it being 0 I
			// guess. Maybe retry later. See Issue 18117.
		}
		// For client requests, Request.ContentLength of 0
		// means either actually 0, or unknown. The only way
		// to explicitly say that the ContentLength is zero is

# Despliegue { #deployment }

Desplegar una aplicación **FastAPI** es relativamente fácil.

## Qué Significa Despliegue { #what-does-deployment-mean }

**Desplegar** una aplicación significa realizar los pasos necesarios para hacerla **disponible para los usuarios**.

### Use the submodel as a type { #use-the-submodel-as-a-type }

And then we can use it as the type of an attribute:

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[18] *}

This would mean that **FastAPI** would expect a body similar to:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {

    "groups" : [ {
      "testProject" : "largeJavaMultiProject",
      "comment" : "We only test the multi-project here since for the monolithic project we would have no cache hits. This would mean we actually would test incremental compilation.",
      "coverage" : {
        "per_commit" : [ "linux" ]
      }
    } ]
  }, {
