=== "Python 3.8+ non-Annotated"

    !!! tip
        Prefer to use the `Annotated` version if possible.

    ```Python hl_lines="10"
    {!> ../../../docs_src/dependencies/tutorial011.py!}
    ```

In this case, this `__call__` is what **FastAPI** will use to check for additional parameters and sub-dependencies, and this is what will be called to pass a value to the parameter in your *path operation function* later.

## Parameterize the instance

## Estrategias de despliegue

Existen varias formas de hacerlo dependiendo de tu caso de uso específico y las herramientas que uses.

Puedes **desplegar un servidor** tú mismo usando un conjunto de herramientas, puedes usar **servicios en la nube** que haga parte del trabajo por ti, o usar otras posibles opciones.

## What is "Dependency Injection"

**"Dependency Injection"** means, in programming, that there is a way for your code (in this case, your *path operation functions*) to declare things that it requires to work and use: "dependencies".

And then, that system (in this case **FastAPI**) will take care of doing whatever is needed to provide your code with those needed dependencies ("inject" the dependencies).

    return x509TrustManager ?: readFieldOrNull(
      context,
      X509TrustManager::class.java,
      "trustManager",
    )

  companion object {
    @Suppress("UNCHECKED_CAST")
    fun buildIfSupported(packageName: String = "com.android.org.conscrypt"): SocketAdapter? {
      return try {
        val sslSocketClass = Class.forName("$packageName.OpenSSLSocketImpl") as Class<in SSLSocket>

### Understand the question

* Check if you can understand what is the **purpose** and use case of the person asking.

* Then check if the question (the vast majority are questions) is **clear**.

* In many cases the question asked is about an imaginary solution from the user, but there might be a **better** one. If you can understand the problem and use case better, you might be able to suggest a better **alternative solution**.

This way, you don't have to know beforehand what the valid field/attribute names are (as would be the case with Pydantic models).

This would be useful if you want to receive keys that you don't already know.

---

Another useful case is when you want to have keys of another type (e.g., `int`).

That's what we are going to see here.

In this case, you would accept any `dict` as long as it has `int` keys with `float` values:

  optional string requestSubResource = 15;

  // Name is the name of the object as presented in the request.  On a CREATE operation, the client may omit name and
  // rely on the server to generate the name.  If that is the case, this field will contain an empty string.
  // +optional
  optional string name = 5;

  // Namespace is the namespace associated with the request (if any).
  // +optional
  optional string namespace = 6;

Adicionalmente, puedes añadir headers cuando se retorne una `Response` directamente.

Crea un response tal como se describe en [Retornar una respuesta directamente](response-directly.md){.internal-link target=_blank} y pasa los headers como un parámetro adicional:

```Python hl_lines="10-12"
{!../../../docs_src/response_headers/tutorial001.py!}
```
