# Classe RenameField
<a name="aws-glue-api-crawler-pyspark-transforms-RenameField"></a>

Renomeia um nó em um `DynamicFrame`.

## Exemplo
<a name="pyspark-RenameField-example"></a>

Recomendamos usar o método [`DynamicFrame.rename_field()`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#aws-glue-api-crawler-pyspark-extensions-dynamic-frame-rename_field) para renomear um campo em um `DynamicFrame`. Para visualizar um código de exemplo, consulte [Exemplo: usar rename\$1field para renomear campos em um `DynamicFrame`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#pyspark-rename_field-example).

<a name="aws-glue-api-crawler-pyspark-transforms-RenameField-__call__"></a>

Renomeia um nó em um `DynamicFrame`.
+ `frame` – O `DynamicFrame` no qual o nó será renomeado (obrigatório).
+ `old_name`: o caminho completo para o nó a ser renomeado (obrigatório).

  Se o nome antigo tiver pontos, o RenameField não funcionará a menos que você posicione os acentos graves (````) ao seu redor. Por exemplo, para substituir `this.old.name` por `thisNewName`, você chamaria RenameField, da seguinte maneira:

  ```
  newDyF = RenameField(oldDyF, "`this.old.name`", "thisNewName")
  ```
+ `new_name`: o novo nome, incluindo o caminho completo (obrigatório).
+ `transformation_ctx` – Uma string única que é usada para identificar informações de estado (opcional).
+ `info` – Uma string associada a erros na transformação (opcional).
+ `stageThreshold`: o número máximo de erros que podem ocorrer na transformação antes que ela falhe (opcional). O padrão é zero.
+ `totalThreshold`: o número máximo de erros que podem ocorrer em geral antes que falhe (opcional). O padrão é zero.
