But in most of the cases where we need to do something like this, we want the model just to **filter/remove** some of the data as in this example.

    val routeUrl = route.address.url

    if (url.port != routeUrl.port) {
      return false // Port mismatch.
    }

    if (url.host == routeUrl.host) {
      return true // Host match. The URL is supported.
    }

    // We have a host mismatch. But if the certificate matches, we're still good.
    return !noCoalescedConnections && handshake != null && certificateSupportHost(url, handshake)
  }

There are many other objects and models that will be automatically converted to JSON (including ORMs, etc). Try using your favorite ones, it's highly probable that they are already supported.

## Recap { #recap }

* Import `FastAPI`.
* Create an `app` instance.
* Write a **path operation decorator** using decorators like `@app.get("/")`.

### 3.2 Lease Versions
- **Lease V1**: Basic lease support (SMB 3.0)
- **Lease V2**: Adds epoch support for better consistency (SMB 3.0.2+)

  To request this behavior, your client software must enable the `WatchListClient` client-go feature gate. Additionally, streaming is only available if supported by the cluster; the API server that you connect to must also support streaming.

		// no action. Thus, we try an innocent seek to the current position

		if pos1 >= 0 && err == nil {
			// Seek seems supported, so perform the real Seek.
			pos2, err := sr.Seek(n-1, io.SeekCurrent)
			if pos2 < 0 || err != nil {
				return err
			}
			seekSkipped = pos2 - pos1
