## Deeply nested models

You can define arbitrarily deeply nested models:

//// tab | Python 3.10+

```Python hl_lines="7  12  18  21  25"
{!> ../../docs_src/body_nested_models/tutorial007_py310.py!}
```

////

Just functions that look the same as the *path operation functions*.

But still, it is very powerful, and allows you to declare arbitrarily deeply nested dependency "graphs" (trees).

/// tip

All this might not seem as useful with these simple examples.

But you will see how useful it is in the chapters about **security**.

    * Validation even for deeply nested JSON objects.

### Custom OpenAPI *path operation* schema

The dictionary in `openapi_extra` will be deeply merged with the automatically generated OpenAPI schema for the *path operation*.

So, you could add additional data to the automatically generated schema.

import java.io.IOException;
import java.io.Reader;
import java.io.StringReader;
import java.util.ArrayList;
import java.util.List;
import java.util.Locale;
import java.util.Set;

/**
 * Deeply opinionated file filter that adds elements to the release notes HTML page.

public class ReleaseNotesTransformer extends FilterReader {
    private File baseCss;
    private File releaseNotesCss;

    ./gradlew wrapper --gradle-distribution-url=file:/path/to/gradle-<version>-all.zip

## Our thanks

We deeply appreciate your effort toward improving Gradle. For any contribution, large or small, you will be immortalized in the release notes for the version you've contributed to.

   * Executor#execute execute}, as in {@code ThreadPoolExecutor.CallerRunsPolicy}.
   *
   * <p>This executor is appropriate for tasks that are lightweight and not deeply chained.
   * Inappropriate {@code directExecutor} usage can cause problems, and these problems can be
   * difficult to reproduce because they depend on timing. For example:
   *
   * <ul>

						s.deleteFile(dstVolumeDir, legacyDataPath, true, false)

						return res, osErrToFileErr(err)

	// Set skipParent to skip mkdirAll() calls for deeply nested objects
	// - if its an overwrite
	// - if its a versioned object
	//
	// This can potentiall reduce syscalls by strings.Split(path, "/")
	// times relative to the object name.
