Generic display views
=====================

The two following generic class-based views are designed to display data. On
many projects they are typically the most commonly used views.

DetailView
----------

.. class:: django.views.generic.detail.DetailView

    While this view is executing, ``self.object`` will contain the object that
    the view is operating upon.

    **Ancestors (MRO)**

    * :class:`django.views.generic.detail.SingleObjectTemplateResponseMixin`
    * :class:`django.views.generic.base.TemplateResponseMixin`
    * :class:`django.views.generic.detail.BaseDetailView`
    * :class:`django.views.generic.detail.SingleObjectMixin`
    * :class:`django.views.generic.base.View`

    **Method Flowchart**

    1. :meth:`dispatch()`
    2. :meth:`http_method_not_allowed()`
    3. :meth:`get_template_names()`
    4. :meth:`get_slug_field()`
    5. :meth:`get_queryset()`
    6. :meth:`get_object()`
    7. :meth:`get_context_object_name()`
    8. :meth:`get_context_data()`
    9. :meth:`get()`
    10. :meth:`render_to_response()`

    **Example views.py**::

        from django.views.generic.detail import DetailView
        from django.utils import timezone

        from articles.models import Article

        class ArticleDetailView(DetailView):

            model = Article

            def get_context_data(self, **kwargs):
                context = super(ArticleDetailView, self).get_context_data(**kwargs)
                context['now'] = timezone.now()
                return context

    **Example urls.py**::

        from django.conf.urls import patterns, url

        from article.views import ArticleDetailView

        urlpatterns = patterns('',
            url(r'^(?P<slug>[-_\w]+)/$', ArticleDetailView.as_view(), name='article-detail'),
        )

ListView
--------

.. class:: django.views.generic.list.ListView

    A page representing a list of objects.

    While this view is executing, ``self.object_list`` will contain the list of
    objects (usually, but not necessarily a queryset) that the view is
    operating upon.

    **Mixins**

    * :class:`django.views.generic.list.ListView`
    * :class:`django.views.generic.list.MultipleObjectTemplateResponseMixin`
    * :class:`django.views.generic.base.TemplateResponseMixin`
    * :class:`django.views.generic.list.BaseListView`
    * :class:`django.views.generic.list.MultipleObjectMixin`
    * :class:`django.views.generic.base.View`

    **Method Flowchart**

    1. :meth:`dispatch()`
    2. :meth:`http_method_not_allowed()`
    3. :meth:`get_template_names()`
    4. :meth:`get_queryset()`
    5. :meth:`get_objects()`
    6. :meth:`get_context_data()`
    7. :meth:`get()`
    8. :meth:`render_to_response()`
