AndrewIngram/django-extra-views: Django's class-based generic views are awesome, let's have more of them.

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.

Supported Python and Django versions: Python 3.6+, Django 2.2-5.1, see tox.ini for an up-to-date list.

Full documentation is available at read the docs.

Install the stable release from pypi (using pip):

pip install django-extra-views

Or install the current master branch from github:

pip install -e git://github.com/AndrewIngram/django-extra-views.git#egg=django-extra-views

Then add 'extra_views' to your INSTALLED_APPS:

INSTALLED_APPS = [
    ...
    'extra_views',
    ...
]

• FormSet and ModelFormSet views - The formset equivalents of FormView and ModelFormView.
• InlineFormSetView - Lets you edit a formset related to a model (using Django's inlineformset_factory).
• CreateWithInlinesView and UpdateWithInlinesView - Lets you edit a model and multiple inline formsets all in one view.
• GenericInlineFormSetView, the equivalent of InlineFormSetView but for GenericForeignKeys.
• Support for generic inlines in CreateWithInlinesView and UpdateWithInlinesView.
• 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 and FormSetSuccessMessageMixin - Generic mixins to display success messages after form submission.

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.

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>

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'

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>
