Requirements

This is extension for django-autocomplete-light so you need to install and configure it too.

Here will be minimum setup for example.

Refer to http://django-autocomplete-light.readthedocs.io/ for more detailed instructions.

Installation

• Install using pip

  pip install django-autocomplete-light dal_admin_filters
  

• Update INSTALLED_APPS. You need too put django-autocomplete-light before admin

  INSTALLED_APPS = [
      'dal',
      'dal_select2',
      'dal_admin_filters',
      #
      'django.contrib.admin',
      ... other stuff there ...
  ]

Configuration

• Create autocomplete view

• Let our models look like this

  class Country(models.Model):
      name = models.CharField(max_length=100, unique=True)
  
      def __str__(self):
          return self.name
  
  
  class Person(models.Model):
      name = models.CharField(max_length=100, unique=True)
      from_country = models.ForeignKey(Country)
  
      def __str__(self):
          return self.name

• Then autocomplete view for country selection will be similar to next

  from your_countries_app.models import Country
  
  class CountryAutocomplete(autocomplete.Select2QuerySetView):
  def get_queryset(self):
      # Don't forget to filter out results depending on the visitor !
      if not self.request.user.is_authenticated():
          return Country.objects.none()
  
      qs = Country.objects.all()
  
      if self.q:
          qs = qs.filter(name__istartswith=self.q)
  
      return qs

• Register view in urls.py

  from your_countries_app.views import CountryAutocomplete
  
  urlpatterns = [
      url(
          r'^country-autocomplete/$',
          CountryAutocomplete.as_view(),
          name='country-autocomplete',
      ),
      url(r'^admin/', admin.site.urls),
  ]

• Use filter in your admin.py

  from django.contrib import admin
  from your_countries_app.models import Country, Person
  from dal_admin_filters import AutocompleteFilter
  
  
  @admin.register(Country)
  class CountryAdmin(admin.ModelAdmin):
      pass
  
  
  class CountryFilter(AutocompleteFilter):
      title = 'Country from'                    # filter's title
      parameter_name = 'from_country'           # field name - ForeignKey to Country model
      autocomplete_url = 'country-autocomplete' # url name of Country autocomplete view
  
  
  @admin.register(Person)
  class PersonAdmin(admin.ModelAdmin):
      class Media:    # Empty media class is required if you are using autocomplete filter
          pass        # If you know better solution for altering admin.media from filter instance
                      #   - please contact me or make a pull request
  
      list_filter = [CountryFilter]

If setup is done right, you will see the Select2 widget in admin filter in Person's changelist view.
