                {"field": "name", "label": "Book Name", "footer-value": "Sum:"},
                {"field": "count", "label": "Stock", "footer-value": lambda: Sum()},
                {"field": "category__name"},
                {"field": "author", "label": "Author", "empty_value": "-"},
                {"field": "is_published", "label": "Is Published", "render": NullBooleanRender("UNKNOWN", "YES", "NO")},

  • label default to _("Export").
  • icon default to None means no icon.
  • filename default to model_name.
  • export-filtered default to False, means always export all queryset without filtering.
  • permissions default to None, means only super admin have permission to do exporting.
  • fields
    • field can be field of the model instance, callable function of the model instance, callable function of the admin which takes model instance parameter. Similar with field name in list_display. field == forloop.counter1 will always display row index, e.g. 1,2,3...
    • label is the header of the column. If missing label, field.verbose_name or function.short_description will be used firstly. If still null, use the field name.
    • render is a callable object that transform the original value to display value.
    • empty_value only works when render is not provided, it is the display value for orignal None value.
    • footer-value is the value display at the bottom row. It can be an instance of Aggregate that accept every item value of this field and calc the final value at last. It can be a staic value.
    • start-row-index is row index where begin to write data. starts from 1.
    • xlsx-template template xlsx file path.
    • show-header True or False means show header or not.
    • col Which col the field value will be stored. Mostly it is 1-based index number. Use list so that you can split long string into multiple cells. Xlsx cell size limit to 32*1024 characters.
