### Pydantic v1 and v2 on the same app { #pydantic-v1-and-v2-on-the-same-app }

It's **not supported** by Pydantic to have a model of Pydantic v2 with its own fields defined as Pydantic v1 models or vice versa.

```mermaid
graph TB
    subgraph "❌ Not Supported"
        direction TB
        subgraph V2["Pydantic v2 Model"]
            V1Field["Pydantic v1 Model"]
        end

Si vous voulez sécuriser votre API, il y a plusieurs meilleures approches possibles, par exemple :

* Vous devez vous assurer d'avoir des modèles Pydantic bien définis pour le corps de la requête et la réponse.
* Configurez toutes les autorisations et tous les rôles nécessaires à l'aide de dépendances.
* Ne stockez jamais de mots de passe en clair, seulement des hachages de mots de passe.

**FastAPI** will **extract** the data for **each field** from the **form data** in the request and give you the Pydantic model you defined.
