from django.http import HttpResponse
from django.contrib import admin
from .models import YourModel

import csv

class YourModelAdmin(admin.ModelAdmin):
    list_display = ('field1', 'field2', 'field3', ...)
    actions = ['export_csv']

    def export_csv(self, request, queryset):
        response = HttpResponse(content_type='text/csv')
        response['Content-Disposition'] = 'attachment; filename="yourmodel_export.csv"'

        writer = csv.writer(response)
        writer.writerow(['Field 1', 'Field 2', 'Field 3', ...])

        for obj in queryset:
            writer.writerow([obj.field1, obj.field2, obj.field3, ...])

        return response

    export_csv.short_description = 'Export selected objects as CSV'

admin.site.register(YourModel, YourModelAdmin)
