The Model Field

You can use TagAutocompleteField() to enable autocompletion right in your models.py. In most cases this is the easiest solution:

from django.db import models
from tagging_autocomplete.models import TagAutocompleteField

class SomeModel(models.Model):
        tags = TagAutocompleteField()

The Form Widget

Alternatively you can use the TagAutocomplete() form widget while creating your form:

from django import forms
from tagging.forms import TagField
from tagging_autocomplete.widgets import TagAutocomplete

class SomeForm(forms.Form):
    tags = TagField(widget=TagAutocomplete())

Optional settings

By default the maximum number of results suggested by the autocompletion is 100. You can modify this number by adding to your settings.py project file the TAGGING_AUTOCOMPLETE_MAX_RESULTS constant. For example:

TAGGING_AUTOCOMPLETE_MAX_RESULTS = 5

By default autocompletion suggests tags that start with a given term. In case you need to show ones that contain the given term, set TAGGING_AUTOCOMPLETE_SEARCH_CONTAINS to True. For example:

TAGGING_AUTOCOMPLETE_SEARCH_CONTAINS = True

By default suggestions are shown right after you enter first character. You can configure this behaviour using TAGGING_AUTOCOMPLETE_MIN_LENGTH. For example:

TAGGING_AUTOCOMPLETE_MIN_LENGTH = 3
