+This module exports two functions that write CSVs, ``render_to_csv_response`` and ``write_csv``. Both of these functions require their own positional arguments as documented above. In addition, they both take the following optional keyword arguments:
- ``field_header_map`` - (default: ``None``) A dictionary mapping names of model fields to column header names. If specified, the csv writer will use these column headers. Otherwise, it will use defer to other parameters for rendering column names.
- ``field_serializer_map`` - (default: ``{}``) A dictionary mapping names of model fields to functions that serialize them to text. For example, ``{'created': (lambda x: x.strftime('%Y/%m/%d')) }`` will serialize a datetime field called ``created``.
- ``use_verbose_names`` - (default: ``True``) A boolean determining whether to use the django field's ``verbose_name``, or to use it's regular field name as a column header. Note that if a given field is found in the ``field_header_map``, this value will take precendence.
- ``field_order`` - (default: ``None``) A list of fields to determine the sort order. This list need not be complete: any fields not specified will follow those in the list with the order they would have otherwise used.
-In addition to the above arguments, ``render_to_csv_response`` takes the following optional keyword argument:
+In addition to the above arguments, ``render_to_csv_response`` takes the following optional keyword arguments:
+- ``filename`` - (default: ``None``) A string used to set a filename in the ``Content-Disposition`` header as part of the returned ``HttpResponse``. If this is not passed, a filename will be automatically generated based on the table name of the QuerySet.
+- ``append_datestamp`` - (default: ``False``) A boolean determining whether to append a timestamp as part of the filename set in the ``Content-Disposition`` header.
- ``streaming`` - (default: ``True``) A boolean determining whether to use ``StreamingHttpResponse`` instead of the normal ``HttpResponse``.
The remaining keyword arguments are *passed through* to the csv writer. For example, you can export a CSV with a different delimiter.
