As `needy` is a required parameter, you would need to set it in the URL:

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

...this would work:

```JSON
{
    "item_id": "foo-item",
    "needy": "sooooneedy"
}
```

And of course, you can define some parameters as required, some as having a default value, and some entirely optional:

    val event = nextEvent() as Open
    return event.webSocket
  }

  fun assertFailure(t: Throwable?) {
    val event = nextEvent() as Failure
    assertThat(event.response).isNull()
    assertThat(event.t).isSameAs(t)
  }

  fun assertFailure(
    cls: Class<out IOException?>?,
    vararg messages: String,
  ) {
    val event = nextEvent() as Failure
    assertThat(event.response).isNull()

If you use this model as an input like here:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

...then the `description` field will **not be required**. Because it has a default value of `None`.

### Input Model in Docs { #input-model-in-docs }

You can confirm that in the docs, the `description` field doesn't have a **red asterisk**, it's not marked as required:

<div class="screenshot">

   *  * **Embedded resources like images and iframes** in browsers use the context as the page in
   *    the address bar and the subject is the URL of an embedded resource.
   *
   *  * **Potentially-destructive navigations such as HTTP POST calls** use the context as the page
   *    originating the navigation, and the subject is the page being navigated to.

            Flags this Mojo as requiring information about the dependencies that would make up the specified class
            path. As the name suggests, this is similar to requiresDependencyResolution and supports the same values.
            The important difference is this will not resolve the files for the dependencies, i.e. the artifacts
            associated with a Maven project can lack a file. As such, this annotation is meant for Mojos that only

The function parameters will be recognized as follows:

* If the parameter is also declared in the **path**, it will be used as a path parameter.
* If the parameter is of a **singular type** (like `int`, `float`, `str`, `bool`, etc) it will be interpreted as a **query** parameter.
* If the parameter is declared to be of the type of a **Pydantic model**, it will be interpreted as a request **body**.
