filter on django-import-export

You can override the export method of resources.ModelResource in your admin.py file, to apply your filter on admin:

from import_export import resources
from finance.models import Price

class ExportData(resources.ModelResource):

    class Meta:
        model = Price

    def export(self, queryset=None, *args, **kwargs):
        # For example only export objects with ids in 1, 2, 3 and 4
        queryset = queryset and queryset.filter(id__in=[1, 2, 3, 4])
        return super(ExportData, self).export(queryset, *args, **kwargs)

To filter only Exported file and not the actual list in the Admin screen you can overwrite the get_export_queryset method

from import_export import resources
from import_export.admin import ImportExportMixin

class ProductAdmin(ImportExportMixin, admin.ModelAdmin):
    resource_class = ProductResource

    # Override of ImportExportMixin.get_export_queryset
    # Filter export to exclude Products where is_active is false
    def get_export_queryset(self, request):
            return Product.objects.filter(is_active=True)

Pass queryset to export method:

queryset = Price.objects.exclude(...)
data = ExportData().export(queryset)
data.csv
