What is this?
=============

This library provides flexible and advanced CRUD generic views for applications
developed with the `Django`_ web framework.

By default the generic views make use of the advanced form classes made
available through `softwarefabrica.django.forms`_, thus automatically using
the optional template-based form rendering, the advanced widgets for date,
time, foreign-key and many-to-many fields, etc.
However it's easy to switch back to `Django`_ default forms and widgets if
desired.

Generic views are a backward-compatible drop-in replacement for those offered by
`Django`_, it's just a matter of importing them from
`softwarefabrica.django.crud.crud` instead of from `django.views.generic`.

In addition, a more flexible set of **Object Oriented views** is available.
Just subclass them as you like, instantiate them and put the instances inside
your URLconf, as if they were regular function views.
In the majority of cases you won't even need to subclass them, since you can go
a long way just by passing the proper parameters to the constructor.

In fact, Object oriented views are so powerful and flexible that plain
functional views are actually instances. They are implemented by the library in
this way:

::

create_object = CreateObjectView()
update_object = UpdateObjectView()
delete_object = DeleteObjectView()
object_detail = DetailObjectView()
object_list = ListObjectView()
