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`_.

.. installation-start

Installation
------------

Install the stable release from pypi (using pip):

.. code-block:: sh

    pip install django-extra-views

Or install the current master branch from github:

.. code-block:: sh

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

Then add ``'extra_views'`` to your ``INSTALLED_APPS``:

.. code-block:: python

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

.. installation-end

.. features-start

Features
--------

- ``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.

.. features-end

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 :code:`FormSetView`, a view which creates a single formset from
:code:`django.forms.formset_factory` and adds it to the context.

.. code-block:: python

    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:

.. code-block:: html

    <form method="post">
      ...
      {{ formset }}
      ...
      <input type="submit" value="Submit" />
    </form>

ModelFormSetView
^^^^^^^^^^^^^^^^^^^^

Define a :code:`ModelFormSetView`, a view which works as :code:`FormSetView`
but instead renders a model formset using
:code:`django.forms.modelformset_factory`.

.. code-block:: python

    from extra_views import ModelFormSetView


    class ItemFormSetView(ModelFormSetView):
        model = Item
        fields = ['name', 'sku']
        template_name = 'item_formset.html'

CreateWithInlinesView or UpdateWithInlinesView
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Define :code:`CreateWithInlinesView` and :code:`UpdateWithInlinesView`,
views which render a form to create/update a model instance and its related
inline formsets. Each of the :code:`InlineFormSetFactory` classes use similar
class definitions as the :code:`ModelFormSetView`.

.. code-block:: python

    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:

.. code-block:: html

    <form method="post">
      ...
      {{ form }}

      {% for formset in inlines %}
        {{ formset }}
      {% endfor %}
      ...
      <input type="submit" value="Submit" />
    </form>
