`uvicorn main:app` əmri aşağıdakılara instinad edir:

* `main`: `main.py` faylı (yəni Python "modulu").
* `app`: `main.py` faylında `app = FastAPI()` sətrində yaratdığımız `FastAPI` obyektidir.

`uvicorn main:app` komutunu şu şekilde açıklayabiliriz:

* `main`: dosya olan `main.py` (yani Python "modülü").
* `app`: ise `main.py` dosyasının içerisinde `app = FastAPI()` satırında oluşturduğumuz `FastAPI` nesnesi.

# Extra Models { #extra-models }

Continuing with the previous example, it will be common to have more than one related model.

This is especially the case for user models, because:

* The **input model** needs to be able to have a password.
* The **output model** should not have a password.
* The **database model** would probably need to have a hashed password.

# Cookie Parameter Models { #cookie-parameter-models }

If you have a group of **cookies** that are related, you can create a **Pydantic model** to declare them. 🍪

This would allow you to **re-use the model** in **multiple places** and also to declare validations and metadata for all the parameters at once. 😎

/// note

This is supported since FastAPI version `0.115.0`. 🤓

/// tip

```Python
from app.routers import items, users
```

### Namenskollisionen vermeiden

Wir importieren das Submodul `items` direkt, anstatt nur seine Variable `router` zu importieren.

## Проверка сгенерированной документации

Вы можете посмотреть объявленные cookies в графическом интерфейсе Документации по пути `/docs`:

/// info | Дополнительная информация

Имейте в виду, что, поскольку **браузеры обрабатывают cookies** особым образом и под капотом, они **не** позволят **JavaScript** легко получить доступ к ним.

## Nested Models { #nested-models }

Each attribute of a Pydantic model has a type.

But that type can itself be another Pydantic model.

So, you can declare deeply nested JSON "objects" with specific attribute names, types and validations.

All that, arbitrarily nested.

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

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