Django Extra Views - The missing class-based generic views for Django
Django-extra-views is a Django package which introduces additional class-based views in order to simplify common design patterns such as those found in the Django admin interface.
Full documentation is available at read the docs.

Features
FormSet
andModelFormSet
views - The formset equivalents ofFormView
andModelFormView
.InlineFormSetView
- Lets you edit a formset related to a model (using Django'sinlineformset_factory
).CreateWithInlinesView
andUpdateWithInlinesView
- Lets you edit a model and multiple inline formsets all in one view.GenericInlineFormSetView
, the equivalent ofInlineFormSetView
but forGenericForeignKeys
.- Support for generic inlines in
CreateWithInlinesView
andUpdateWithInlinesView
. - Support for naming each inline or formset in the template context with
NamedFormsetsMixin
. SortableListMixin
- Generic mixin for sorting functionality in your views.SearchableListMixin
- Generic mixin for search functionality in your views.SuccessMessageMixin
andFormSetSuccessMessageMixin
- Generic mixins to display success messages after form submission.
Still to do
Add support for pagination in ModelFormSetView and its derivatives, the goal being to be able to mimic the change_list view in Django's admin. Currently this is proving difficult because of how Django's MultipleObjectMixin handles pagination.
Quick Examples
FormSetView
Define a FormSetView
, a view which creates a single formset from
django.forms.formset_factory
and adds it to the context.
from extra_views import FormSetView
from my_forms import AddressForm
class AddressFormSet(FormSetView):
form_class = AddressForm
template_name = 'address_formset.html'
Then within address_formset.html
, render the formset like this:
<form method="post">
...
{{ formset }}
...
<input type="submit" value="Submit" />
</form>
ModelFormSetView
Define a ModelFormSetView
, a view which works as FormSetView
but instead renders a model formset using
django.forms.modelformset_factory
.
from extra_views import ModelFormSetView
class ItemFormSetView(ModelFormSetView):
model = Item
fields = ['name', 'sku']
template_name = 'item_formset.html'
CreateWithInlinesView or UpdateWithInlinesView
Define CreateWithInlinesView
and UpdateWithInlinesView
,
views which render a form to create/update a model instance and its related
inline formsets. Each of the InlineFormSetFactory
classes use similar
class definitions as the ModelFormSetView
.
from extra_views import CreateWithInlinesView, UpdateWithInlinesView, InlineFormSetFactory
class ItemInline(InlineFormSetFactory):
model = Item
fields = ['sku', 'price', 'name']
class ContactInline(InlineFormSetFactory):
model = Contact
fields = ['name', 'email']
class CreateOrderView(CreateWithInlinesView):
model = Order
inlines = [ItemInline, ContactInline]
fields = ['customer', 'name']
template_name = 'order_and_items.html'
class UpdateOrderView(UpdateWithInlinesView):
model = Order
inlines = [ItemInline, ContactInline]
fields = ['customer', 'name']
template_name = 'order_and_items.html'
Then within order_and_items.html
, render the formset like this:
<form method="post">
...
{{ form }}
{% for formset in inlines %}
{{ formset }}
{% endfor %}
...
<input type="submit" value="Submit" />
</form>
