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>
