django-tagging TagField ~~~~~~~~~~~~~~~~~~~~~~~ Model example ============= Consider such a model, using ``django-tagging`` to handle tags for a model: .. code-block:: python from django.db import models from tagging.fields import TagField class TestModel(models.Model): name = models.CharField(max_length=200) tags = TagField() def __str__(self): return self.name View example ============ The :ref:`QuerySet view` works here too: we're relying on Select2 and a QuerySet of Tag objects: .. code-block:: python from dal import autocomplete from tagging.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 .. note:: Don't forget to :ref:`register-view`. 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 :py:class:`dal_select2_taggit.widgets.TaggitSelect2`. It is compatible with the default form field created by the model field: ``TagField``. Example: .. code-block:: python class TestForm(autocomplete.FutureModelForm): class Meta: model = TestModel fields = ('name',) widgets = { 'tags': autocomplete.TaggingSelect2( 'your-taggit-autocomplete-url' ) }
