### Pydantic v1 et v2 dans la même application { #pydantic-v1-and-v2-on-the-same-app }

Pydantic ne prend pas en charge le fait d'avoir un modèle Pydantic v2 contenant des champs eux-mêmes définis comme des modèles Pydantic v1, et inversement.

```mermaid
graph TB
    subgraph "❌ Not Supported"

/// warning | 警告

请注意，由于 Pydantic 团队自 Python 3.14 起不再在较新的 Python 版本中支持 Pydantic v1，使用 `pydantic.v1` 在 Python 3.14 及更高版本中也不受支持。

///

### 同一应用中同时使用 Pydantic v1 与 v2 { #pydantic-v1-and-v2-on-the-same-app }

Pydantic 不支持在一个 Pydantic v2 模型的字段中定义 Pydantic v1 模型，反之亦然。

The same way, you can declare responses of lists of objects.

For that, use the standard Python `list`:
