Adding a page list
============================================

Most wikis have a feature that lets you view an index of the pages. To add one,
we'll start with a new template, ``pagelist.html``. We'll copy ``page.html`` so
that we don't have to write the boilerplate.

.. code-block:: bash

    cd wiki20/templates
    cp page.html pagelist.html

After editing, our ``pagelist.html`` looks like:

.. literalinclude:: ../../project_code/wiki_root/snapshots/9/wiki20/templates/pagelist.html
   :linenos:
   :language: html

**19-22**  This section represents the Genshi code of interest.
You can guess that the ``py:for`` is a python ``for`` loop,
modified to fit into Genshi's XML.
It iterates through each of the ``pages`` (which we'll send in via the
controller, using a modification you'll see next).
For each one, ``Page Name Here`` is replaced by ``pagename``, as is the URL.

We must also modify ``controller/root.py`` to implement ``pagelist`` and to 
create and pass ``pages`` to our template:


.. literalinclude:: ../../project_code/wiki_root/snapshots/8/wiki20/controllers/root.py
   :linenos:
   :language: python

**45-47**  We select all of the ``Page`` objects from the database,
and order them by pagename.

We can also modify ``page.html`` so that the link to the page list is available on
every page (line 28):

.. literalinclude:: ../../project_code/wiki_root/snapshots/9/wiki20/templates/page.html
   :linenos:
   :language: html

You can see your pagelist by clicking the link on a page or by
going directly to http://localhost:8080/pagelist.
