-   לאמת שה - `item_id` הוא מטיפוס `int` בבקשות `GET` ו - `PUT`.
    -   אם הוא לא, הלקוח יראה שגיאה ברורה ושימושית.
-   לבדוק האם קיים פרמטר שאילתא בשם `q` (קרי `http://127.0.0.1:8000/items/foo?q=somequery`) לבקשות `GET`.
    -   מאחר והפרמטר `q` מוגדר עם <code dir="ltr"> = None</code>, הוא אופציונלי.
    -   לולא ה - `None` הוא היה חובה (כמו הגוף במקרה של `PUT`).

  - যদি না হয় তবে ক্লায়েন্ট একটি উপযুক্ত, পরিষ্কার ত্রুটি দেখতে পাবেন।
- `GET` অনুরোধের জন্য একটি ঐচ্ছিক ক্যুয়েরি প্যারামিটার নামক `q` (যেমন `http://127.0.0.1:8000/items/foo?q=somequery`) আছে কি তা চেক করবে।
  - যেহেতু `q` প্যারামিটারটি `= None` দিয়ে ঘোষণা করা হয়েছে, তাই এটি ঐচ্ছিক।
  - `None` ছাড়া এটি প্রয়োজনীয় হতো (যেমন `PUT` এর ক্ষেত্রে হয়েছে)।

Containers are mainly a tool to simplify the process of **building and deploying** an application, but they don't enforce a particular approach to handle these **deployment concepts**, and there are several possible strategies.

The **good news** is that with each different strategy there's a way to cover all of the deployment concepts. 🎉

Let's review these **deployment concepts** in terms of containers:

* HTTPS
* Running on startup
* Restarts

    table of data to be supplied by an application program that uses
    the facility, other than as an argument passed when the facility
    is invoked, then you must make a good faith effort to ensure that,
    in the event an application does not supply such function or
    table, the facility still operates, and performs whatever part of
    its purpose remains meaningful.

* Validará que el `item_id` sea del tipo `int` para requests `GET` y `PUT`.
    * Si no lo es, el cliente verá un error útil y claro.
* Comprobará si hay un parámetro de query opcional llamado `q` (como en `http://127.0.0.1:8000/items/foo?q=somequery`) para requests `GET`.
    * Como el parámetro `q` está declarado con `= None`, es opcional.
    * Sin el `None` sería requerido (como lo es el body en el caso con `PUT`).
