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

Renames a node within a `DynamicFrame`.

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

We recommend that you use the [`DynamicFrame.rename_field()`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#aws-glue-api-crawler-pyspark-extensions-dynamic-frame-rename_field) method to rename a field in a `DynamicFrame`. To view a code example, see [Example: Use rename\$1field to rename fields in a `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>

Renames a node within a `DynamicFrame`.
+ `frame` – The `DynamicFrame` in which to rename a node (required).
+ `old_name` – The full path to the node to rename (required).

  If the old name has dots in it, RenameField will not work unless you place backticks around it (````). For example, to replace `this.old.name` with `thisNewName`, you would call RenameField as follows:

  ```
  newDyF = RenameField(oldDyF, "`this.old.name`", "thisNewName")
  ```
+ `new_name` – The new name, including full path (required).
+ `transformation_ctx` – A unique string that is used to identify state information (optional).
+ `info` – A string associated with errors in the transformation (optional).
+ `stageThreshold` – The maximum number of errors that can occur in the transformation before it errors out (optional). The default is zero.
+ `totalThreshold` – The maximum number of errors that can occur overall before processing errors out (optional). The default is zero.
