Is there a way I can download the headers only as a file in Django ImportExportModelAdmin

Question

Is there a way to just download a file that contains only the field titles?

For example, the download template button will download a file that has all the necessary fields as shown in the help text.

The downloaded file would look like this:

Here is one way. You need to declare a resource and override the export() method so that it creates a new Dataset containing only headers.

class BookResource(ModelResource):

    class Meta:
        model = Book

    def export(self, queryset=None, *args, **kwargs):
        data = super().export(queryset, args, kwargs)
        return tablib.Dataset(headers=data.headers)
