django-taggit TaggableManager#

Model example#

Consider such a model, using django-taggit to handle tags for a model:

from django.db import models

from taggit.managers import TaggableManager

class TestModel(models.Model):
    name = models.CharField(max_length=200)

    tags = TaggableManager()

    def __str__(self):

View example#

The QuerySet view works here too: we’re relying on Select2 and a QuerySet of Tag objects:

from dal import autocomplete

from taggit.models import Tag

class TagAutocomplete(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 Tag.objects.none()

        qs = Tag.objects.all()

        if self.q:
            qs = qs.filter(name__istartswith=self.q)

        return qs

    def get_create_option(self, context, q):
        return []

Don’t forget to Register the autocomplete view.


For more complex filtering, refer to official documentation for the QuerySet API.

Form example#

As usual, we need a backend-aware widget that will make only selected choices to render initially, to avoid butchering the database.

As we’re using a QuerySet of Tag and Select2 in its “tag” appearance, we’ll use TaggitSelect2. It is compatible with the default form field created by the model field: TaggeableManager - which actually inherits django.db.models.fields.Field and django.db.models.fields.related.RelatedField and not from django.db.models.Manager.


class TestForm(autocomplete.FutureModelForm):
    class Meta:
        model = TestModel
        fields = ('name',)
        widgets = {
            'tags': autocomplete.TaggitSelect2(
