### Define a submodel { #define-a-submodel }

For example, we can define an `Image` model:

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[7:9] *}

### Use the submodel as a type { #use-the-submodel-as-a-type }

And then we can use it as the type of an attribute:

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[18] *}

This would mean that **FastAPI** would expect a body similar to:

```JSON
{

  @Throws(IOException::class)
  internal fun planConnect(): ConnectPlan {
    // Use a route from a preceding coalesced connection.
    val localNextRouteToTry = nextRouteToTry
    if (localNextRouteToTry != null) {
      nextRouteToTry = null
      return planConnectToRoute(localNextRouteToTry)
    }

    // Use a route from an existing route selection.
    val existingRouteSelection = routeSelection

Note that by allowing for this limited form of manual memory allocation
that use-after-free bugs are possible with regular Go values. This package
limits the impact of these use-after-free bugs by preventing reuse of freed
