### 同一應用同時使用 Pydantic v1 與 v2 { #pydantic-v1-and-v2-on-the-same-app }

Pydantic 不支援在 Pydantic v2 模型的欄位中使用 Pydantic v1 模型，反之亦然。

```mermaid
graph TB
    subgraph "❌ Not Supported"
        direction TB
        subgraph V2["Pydantic v2 Model"]
            V1Field["Pydantic v1 Model"]
        end
        subgraph V1["Pydantic v1 Model"]

///

### 같은 앱에서 Pydantic v1과 v2 함께 사용하기 { #pydantic-v1-and-v2-on-the-same-app }

Pydantic에서는 Pydantic v2 모델의 필드를 Pydantic v1 모델로 정의하거나 그 반대로 하는 것을 **지원하지 않습니다**.

```mermaid
graph TB
    subgraph "❌ Not Supported"
        direction TB
        subgraph V2["Pydantic v2 Model"]
            V1Field["Pydantic v1 Model"]
        end
        subgraph V1["Pydantic v1 Model"]

### 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
        subgraph V1["Pydantic v1 Model"]
