Views by author, categories, tags is not enough :).

The idea is to create specific pages based on a query search. Imagine that we want to customize the homepage of the Weblog, because we write on a variety of subjects and we don’t want to bore visitors who aren’t interested in some really specific entries. Another usage of the channels is for SEO, for aggregating entries under a well-formatted URL.

For doing that Zinnia provides a view called EntryChannel.

If we take our first example, we will do like that for customizing the Weblog homepage in our project’s

from zinnia.views.channels import EntryChannel

url(r'^weblog/$', EntryChannel.as_view(
    query='category:python OR category:django')),
url(r'^weblog/', include('zinnia.urls', namespace='zinnia')),

The first URL will handle the homepage of the blog instead of the default URL provided by Zinnia.

As we can see, the only required argument for this view is query. This parameter represents a query search string. This string will be interpreted by the search engine activated in Zinnia and return a list of entries (See Search Engines for more informations).

So our homepage will only display entries filled under the categories Python or Django.

The others parameters handled by the channel view are the same that the generic view named ListView.
