# Développement - Contribuer

Tout d'abord, vous voudrez peut-être voir les moyens de base pour [aider FastAPI et obtenir de l'aide](help-fastapi.md){.internal-link target=_blank}.

## Développement

Si vous avez déjà cloné le dépôt et que vous savez que vous devez vous plonger dans le code, voici quelques directives pour mettre en place votre environnement.

### Environnement virtuel avec `venv`

With SQLModel, we can use **inheritance** to **avoid duplicating** all the fields in all the cases.

#### `HeroBase` - the base class

Let's start with a `HeroBase` model that has all the **fields that are shared** by all the models:

* `name`
* `age`

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[7:9] hl[7:9] *}

The available features and the components that comprise each feature are as follows:

| Feature | Components |
|---------|------------|
CRDs, and other cluster wide configs | Base
Traffic Management | Pilot
Security | Pilot
Configuration management | Pilot
AutoInjection | Pilot
Gateways | Ingress gateway
Gateways | Egress gateway
Policy | Policy (deprecated)

/**
 * Base kerberos authenticator

 * Uses a subject that contains kerberos credentials for use in GSSAPI context establishment.

This will be especially useful when you use it in a **large code base** where you use **the same dependencies** over and over again in **many *path operations***.

## To `async` or not to `async`

///

	**FastAPI** saberá que pode usar a classe `OAuth2PasswordBearer` (declarada na dependência) para definir o esquema de segurança na OpenAPI porque herda de `fastapi.security.oauth2.OAuth2`, que por sua vez herda de `fastapi.security.base.Securitybase`.

	 Todos os utilitários de segurança que se integram com OpenAPI (e na documentação da API automática) herdam de `SecurityBase`, é assim que **FastAPI** pode saber como integrá-los no OpenAPI.
