### Create the `Settings` object { #create-the-settings-object }

Import `BaseSettings` from Pydantic and create a sub-class, very much like with a Pydantic model.

The same way as with Pydantic models, you declare class attributes with type annotations, and possibly default values.

	if err != nil {
		return
	}
	ctx = context.WithValue(ctx, config.ContextKeyForTargetFromConfig, tgts)
	if verr := validateConfig(ctx, result.Cfg, result.SubSys); verr != nil {
		err = badConfigErr{Err: verr}
		return
	}

	// Check if subnet proxy being set and if so set the same value to proxy of subnet
	// target of logger webhook configuration

## Forbid Extra Query Parameters { #forbid-extra-query-parameters }

In some special use cases (probably not very common), you might want to **restrict** the query parameters that you want to receive.

You can use Pydantic's model configuration to `forbid` any `extra` fields:

	KMSVersions := []string{
		kmsAPIVersionPrefix,
	}

	gz, err := gzhttp.NewWrapper(gzhttp.MinSize(1000), gzhttp.CompressionLevel(gzip.BestSpeed))
	if err != nil {
		// Static params, so this is very unlikely.
		logger.Fatal(err, "Unable to initialize server")
	}

	for _, version := range KMSVersions {
		// KMS Status APIs

#### Retourner des *membres d'énumération*

Vous pouvez retourner des *membres d'énumération* dans vos *fonctions de chemin*, même imbriquée dans un JSON (e.g. un `dict`).

Ils seront convertis vers leurs valeurs correspondantes (chaînes de caractères ici) avant d'être transmis au client :

{* ../../docs_src/path_params/tutorial005.py hl[18,21,23] *}

Le client recevra une réponse JSON comme celle-ci :

```JSON

        assertNotNull(deleteQuery);
    }

    public void test_execute_withLongExceptionMessage() {
        // Create a very long exception message
        StringBuilder longMessage = new StringBuilder("Error: ");
        for (int i = 0; i < 100; i++) {
            longMessage.append("This is a very long error message part ").append(i).append(". ");
        }
        final String errorMessage = longMessage.toString();

This is normally the best way to contribute to the project.

## External Contributions

External contributions are very welcome and appreciated, including answering questions, submitting PRs, etc. 🙇‍♂️

This is just a **quick tutorial / refresher** about Python type hints. It covers only the minimum necessary to use them with **FastAPI**... which is actually very little.

**FastAPI** is all based on these type hints, they give it many advantages and benefits.

But even if you never use **FastAPI**, you would benefit from learning a bit about them.

/// note

In this case, you have:

* `ItemsService`
* `UsersService`

### Client Method Names { #client-method-names }

Right now, the generated method names like `createItemItemsPost` don't look very clean:

```TypeScript
ItemsService.createItemItemsPost({name: "Plumbus", price: 5})
```

...that's because the client generator uses the OpenAPI internal **operation ID** for each *path operation*.
