Usage

Prepare resource for your model

# apps/books/resources.py
from import_export_extensions.resources import CeleryModelResource

from .. import models


class BookResource(CeleryModelResource):

    class Meta:
        model = models.Book

Use CeleryImportExportMixin class and set resource_class in admin model to import/export via Django Admin

# apps/books/admin.py
from django.contrib import admin

from import_export_extensions.admin import CeleryImportExportMixin

from .. import resources


@admin.register(models.Book)
class BookAdmin(CeleryImportExportMixin, admin.ModelAdmin):
    resource_class = resources.BookResource

Prepare view sets to import/export via API

# apps/books/api/views.py
from .. import resources

from import_export_extensions.api import views


class BookExportViewSet(views.ExportJobViewSet):
    resource_class = resources.BookResource


class BookImportViewSet(views.ImportJobViewSet):
    resource_class = resources.BookResource

If you use multiple or custom admin site, register required models to them

# app/admin.py
from import_export_extensions.models import ExportJob
from import_export_extensions.admin.model_admins.export_job_admin import ExportJobAdmin

from django.apps import AppConfig

custom_admin_site = BaseAdminSite(name="custom_admin")
# ...
cutom_admin_site.register(ExportJob, ExportJobAdmin)

Don't forget to configure Celery if you want to run import/export in background
