How to Use¶
1. Add the add-another button¶
Wrap django_addanother.widgets.AddAnotherWidgetWrapper around your widget to show the add-another button next to it.
For example, let’s say we want to add add-another buttons to a model form:
from django.core.urlresolvers import reverse_lazy
from django_addanother.widgets import AddAnotherWidgetWrapper
class FooForm(forms.ModelForm):
class Meta:
...
widgets = {
'sender': AddAnotherWidgetWrapper(
forms.Select,
reverse_lazy('person_create'),
),
'recipients': AddAnotherWidgetWrapper(
forms.SelectMultiple,
reverse_lazy('person_create'),
)
}
This will add an add-another button next to the sender and recipients fields. When clicked, these will open the 'person_create' URL in a popup.
Important
Be sure to include form media and jQuery in your templates:
{{ form }}
<script src="{% static 'admin/js/vendor/jquery/jquery.js' %}"></script>
{{ form.media }}
2. Make your view popup-compatible¶
Note
This assumes you’re using Django’s generic CreateView. django-addanother doesn’t support function-based views at the point of writing. You’ll have to convert any function-based views to Class Based Views first.
Making your CreateView compatible with django-addanother is as simple as making it inherit the django_addanother.views.CreatePopupMixin class:
from django_addanother.views import CreatePopupMixin
class PersonCreate(CreatePopupMixin, CreateView):
model = Foo
...
This overwrites your view’s form_valid() method to return a special JavaScript response in case a form has been submitted from a popup.
You may want to hide header, footer and navigation elements for the popups. When the create view is opened in a popup, the view.is_popup template variable is set:
{% if not view.is_popup %} <nav>...</nav> {% endif %}
