python - Django - Autocomplete_Light's "Add Another" popup declares: "'initial' is an invalid keyword argument for this function" -

i working on getting "add another" popup work django-autocomplete_light.

following along in docs:

http://django-autocomplete-light.readthedocs.org/en/latest/addanother.html

i have set urls:

import autocomplete_light.shortcuts al  almondking.financiallogs import models almondking.financiallogs import forms  urlpatterns = [     url(r'^branches/autocreate/$', al.createview.as_view(         model=models.companybranch, form_class=forms.companybranch),         name='branch_autocreate'), ] 

and autocomplete_light_registry.py

al.register(companybranch,     search_fields=['^branch_name'],     attrs={         'placeholder': 'branch',         'data-autocomplete-minimum-characters': 1,     },     widget_attrs={         'data-widget-maximum-values': 1,         'class': 'modern-style',     },     add_another_url_name='company:branch_autocreate', ) 

however, when click plus sign add new related object, following error:

typeerror @ /company/branches/autocreate/

'initial' invalid keyword argument function
