Extra class-based views for Django

Django’s class-based generic views are great, they let you accomplish a large number of web application design patterns in relatively few lines of code. They do have their limits though, and that’s what this library of views aims to overcome.

Installation

Installing from github.

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

Features so far

• FormSet and ModelFormSet views - The formset equivalents of FormView and ModelFormView.

• InlineFormSetView - Lets you edit formsets related to a model (uses inlineformset_factory)

• GenericInlineFormSetView, the equivalent of InlineFormSetView but for GenericForeignKeys

• CreateWithInlinesView and UpdateWithInlinesView - Lets you edit a model and its relations

• Support for generic inlines in CreateWithInlinesView and UpdateWithInlinesView

Notes

• NamedFormsetMixin removed - context behavior baked directly into views, with inline_context_names and formset_context_name.

• Removed MultiFormView, SearchableMixin, SortableListMixin, CalendarMonthView.

• The InlineFormSet and GenericFormSet classes are now just regular classes, not views.

Still to do

Adding support for pagination in ModelFormSetView and its derivatives should now be simpler.

Examples

Defining a FormSetView.

from extra_views import FormSetView


class AddressFormSet(FormSetView):
    form_class = AddressForm
    template_name = 'address_formset.html'

Defining a ModelFormSetView.

from extra_views import ModelFormSetView


class ItemFormSetView(ModelFormSetView):
    model = Item
    template_name = 'item_formset.html'

Defining a CreateWithInlinesView and an UpdateWithInlinesView.

from extra_views import CreateWithInlinesView, UpdateWithInlinesView, InlineFormSet
from extra_views.generic import GenericInlineFormSet


class ItemInline(InlineFormSet):
    model = Item


class TagInline(GenericInlineFormSet):
    model = Tag


class CreateOrderView(CreateWithInlinesView):
    model = Order
    inlines = [ItemInline, TagInline]


class UpdateOrderView(UpdateWithInlinesView):
    model = Order
    inlines = [ItemInline, TagInline]


# Example URLs.
urlpatterns = patterns('',
    url(r'^orders/new/$', CreateOrderView.as_view()),
    url(r'^orders/(?P<pk>\d+)/$', UpdateOrderView.as_view()),
)
