如何在django-import-export中仅包含CSV，XLS，XLSX选项? [英] How to have only CSV, XLS, XLSX options in django-import-export?

问题描述

我为我的项目实现了 django-import-export .

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

默认情况下，它为我提供了导入和导出的许多文件格式选项.

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

如何将文件格式限制为仅CSV，XLS和XLSX?

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

推荐答案

您可以覆盖ExportMixin的get_export_formats()方法:

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()]
