Because this dependency function doesn't have any scope requirements itself, we can use `Depends` with `oauth2_scheme`, we don't have to use `Security` when we don't need to specify security scopes.

We also declare a special parameter of type `SecurityScopes`, imported from `fastapi.security`.

And the proxy would be **"stripping"** the **path prefix** on the fly before transmitting the request to the app server (probably Uvicorn via FastAPI CLI), keeping your application convinced that it is being served at `/app`, so that you don't have to update all your code to include the prefix `/api/v1`.

Up to here, everything would work as normally.

### Model for Output

But if you use the same model as an output, like here:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py hl[19] *}

...then because `description` has a default value, if you **don't return anything** for that field, it will still have that **default value**.

### Model for Output Response Data

    }

    public String getBaseVersion() {
        // Don't want the artifact's version in here, as this is stored in the directory above that
        return null;
    }

    public Object getKey() {
        return "artifact " + artifact.getGroupId() + ":" + artifact.getArtifactId();
    }

    public boolean isSnapshot() {
        // Don't consider the artifact's version in here, as this is stored in the directory above that

Let's imagine that loading the model can **take quite some time**, because it has to read a lot of **data from disk**. So you don't want to do it for every request.

            if (path.isAbsolute()) {
                // path is already absolute, we're done
            } else if (path.getPath().startsWith(File.separator)) {
                // drive-relative Windows path, don't align with base dir but with drive root
                result = path.getAbsoluteFile();
            } else {
                // an ordinary relative path, align with base dir

You only give `Depends` a single parameter.

This parameter must be something like a function.

You **don't call it** directly (don't add the parenthesis at the end), you just pass it as a parameter to `Depends()`.

And that function takes parameters in the same way that *path operation functions* do.
