# Response - Change Status Code

You probably read before that you can set a default [Response Status Code](../tutorial/response-status-code.md){.internal-link target=_blank}.

But in some cases you need to return a different status code than the default.

## Use case

For example, imagine that you want to return an HTTP status code of "OK" `200` by default.

    implementation(libs.commonsLang)
    implementation(libs.maven3SettingsBuilder)
    implementation(libs.maven3Model)
    implementation(libs.slf4jApi)
    implementation(libs.plexusUtils)

    // We need to handle the Maven dependencies specially otherwise it breaks some cross version tests
    // TODO Figure out why and fix it - Move the two deps below to implementation and api and run ProjectTheExtensionCrossVersionSpec

            }
            legend(sb.toString());
        }
        if (highLevelErrors.canSuggestWriteMetadata()) {
            // the else is just to avoid telling people to use `--write-verification-metadata` if we suspect compromised dependencies

      handleAllCompleted();
      return;
    }

    // NOTE: If we ever want to use a custom executor here, have a look at CombinedFuture as we'll
    // need to handle RejectedExecutionException

    if (allMustSucceed) {
      // We need fail fast, so we have to keep track of which future failed so we can propagate
      // the exception immediately

The link:https://kotlinlang.org/docs/delegated-properties.html[Kotlin delegated properties] are part of the Gradle Kotlin DSL.
You need to explicitly specify the type as `String`.
If you need to branch depending on the presence of the property, you can also use `String?` and check for `null`.

[.multi-language-text.lang-groovy]

If you are developing an application with an older non-async framework, and can work with all its defaults, **it can be a great tool**.

But if you need to change some of the defaults, support more than one predefined database, work with an async framework (like FastAPI), etc, you will need to add quite some complex extra code to override those defaults.

# JSON Compatible Encoder

There are some cases where you might need to convert a data type (like a Pydantic model) to something compatible with JSON (like a `dict`, `list`, etc).

For example, if you need to store it in a database.

For that, **FastAPI** provides a `jsonable_encoder()` function.

## Using the `jsonable_encoder`

Let's imagine that you have a database `fake_db` that only receives JSON compatible data.
