How to have only CSV, XLS, XLSX options in django-

问题:

I have implemented django-import-export for my project.

It provides me many file format options by default fro both import and export.

How to restrict the file formats to only CSV, XLS and XLSX ?

You can override the get_export_formats() method of the ExportMixin:

from import_export.formats import base_formats


class MyAdmin(ExportMixin):
    # your normal stuff
    def get_export_formats(self):
            """
            Returns available export formats.
            """
            formats = (
                  base_formats.CSV,
                  base_formats.XLS,
                  base_formats.XLSX,
                  base_formats.TSV,
                  base_formats.ODS,
                  base_formats.JSON,
                  base_formats.YAML,
                  base_formats.HTML,
            )
            return [f for f in formats if f().can_export()]
