django-extra-views 0.2.2

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 pypi (using pip).

pip install django-extra-views

Installing from github.

pip install -e git://github.com/AndrewIngram/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)

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

• GenericInlineFormSetView, the equivalent of InlineFormSetView but for GenericForeignKeys

• Support for generic inlines in CreateWithInlinesView and UpdateWithInlinesView

Still to do

I’d like to 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.

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()),
)

More descriptive examples to come.
