# Modelos de Parâmetros de Consulta { #query-parameter-models }

Se você possui um grupo de **parâmetros de consultas** que são relacionados, você pode criar um **modelo Pydantic** para declará-los.

Isso permitiria que você **reutilizasse o modelo** em **diversos lugares**, e também declarasse validações e metadados de todos os parâmetros de uma única vez. 😎

/// note | Nota

Isso é suportado desde o FastAPI versão `0.115.0`. 🤓

  patches should only highlight the actual difference, not being disturbed by any formatting issues:
  + Only use spaces for indentation.
  + Create minimal diffs - disable on save actions like reformat source code or organize imports.
    If you feel the source code should be reformatted, create a separate PR for this change.
  + Check for unnecessary whitespace with `git diff --check` before committing.

## アンダースコア変換の無効化 { #disable-convert-underscores }

通常のヘッダーパラメータと同様に、パラメータ名にアンダースコアがある場合は**自動的にハイフンに変換**されます。

例えば、コード上でヘッダーパラメータ `save_data` を定義すると、想定される HTTP ヘッダーは `save-data` となり、ドキュメント上にもそのように表示されます。

何らかの理由でこの自動変換を無効化する必要がある場合、ヘッダーパラメータ用の Pydantic モデルでも無効化できます。
