**FastAPI** faz uso dele para que você veja o erro no seu log, caso você utilize um modelo de Pydantic em `response_model`, e seus dados tenham erro.

Contudo, o cliente ou usuário não terão acesso a ele. Ao contrário, o cliente receberá um "Internal Server Error" com o HTTP status code `500`.

### Memory per Process

Now, when the program loads things in memory, for example, a machine learning model in a variable, or the contents of a large file in a variable, all that **consumes a bit of the memory (RAM)** of the server.

And if that `Response` has a JSON media type (`application/json`), like is the case with the `JSONResponse` and `UJSONResponse`, the data you return will be automatically converted (and filtered) with any Pydantic `response_model` that you declared in the *path operation decorator*.

!!! note

    val prefix = testType.prefix
    val sourceSet = the<SourceSetContainer>().getByName("${prefix}Test")

    // We apply lazy as we don't want to depend on the order
    plugins.withType<IdeaPlugin> {
        with(model) {
            module {
                testSources.from(sourceSet.java.srcDirs, sourceSet.the<GroovySourceDirectorySet>().srcDirs)
                testResources.from(sourceSet.resources.srcDirs)
            }
        }

[Calico CNI plugin](https://github.com/projectcalico/cni-plugin).

Specifically:

- The CNI installation script is containerized and deployed as a daemonset in k8s.  The relevant calico k8s manifests were used as the model for the istio-cni plugin's manifest:

**FastAPI** использует его для того, чтобы, если вы используете Pydantic-модель в `response_model`, и ваши данные содержат ошибку, вы увидели ошибку в журнале.

Но клиент/пользователь этого не увидит. Вместо этого клиент получит сообщение "Internal Server Error" с кодом состояния HTTP `500`.

Und wenn diese `Response` einen JSON-Medientyp (`application/json`) hat, wie es bei `JSONResponse` und `UJSONResponse` der Fall ist, werden die von Ihnen zurückgegebenen Daten automatisch mit jedem Pydantic `response_model` konvertiert (und gefiltert), das Sie im *Pfadoperation-Dekorator* deklariert haben.

!!! note "Hinweis"

/**
 * Test lifecycle tasks that correspond to CIBuildModel.TestType (see .teamcity/Gradle_Check/model/CIBuildModel.kt).
 */
fun TaskContainer.registerCITestDistributionLifecycleTasks() {
    val ciGroup = "CI Lifecycle"

    register("quickTest") {

Ayrıca, Pydantic modelleri de döndürebilirsiniz (bu konu ileriki aşamalarda irdelenecektir).

Otomatik olarak JSON'a dönüştürülecek (ORM'ler vb. dahil) başka birçok nesne ve model vardır. En beğendiklerinizi kullanmayı deneyin, yüksek ihtimalle destekleniyordur.

## Özet

* `FastAPI`'yı projemize dahil ettik.
* Bir `app` örneği oluşturduk.
