How to include the toctree in the sidebar of each page

Including the 'globaltoc.html' has a drawback in that it doesn't show both the global and local toc for the page you're viewing.

It appears that others were irked about this limitation and resulted in the subsequent development of an extension to support a full toc in the sidebar, checkout: https://pypi.python.org/pypi/sphinxcontrib-fulltoc

Nothing will appear in the "Navigation" section of the default Sphinx sidebar until you add the names of files that you want to scan for section headings to the toctree:: directive in your .rst file.

For example, if you want all the headings of your index.rst file to appear in the Navigation pane, write index (without the extension) in the toctree:: list like so:

My Level 1 Heading
==================

Glorious content.

My Level 2 Heading
------------------

More content


.. toctree::
   :maxdepth: 2
   :caption: Contents:

   index

The crucial bit is adding index right there at the end. If you're like me, you start your projects with the auto-generated template from sphinx-quickstart, which (at time of writing) populates your .rst files with EMPTY toctrees.

You can customize your html sidebar in conf.py.

The default html sidebar consists of 4 templates:

['localtoc.html', 'relations.html', 'sourcelink.html', 'searchbox.html']

In conf.py you could change localtoc.html to globaltoc.html like this:

html_sidebars = { '**': ['globaltoc.html', 'relations.html', 'sourcelink.html', 'searchbox.html'] }

Since this in the end this will be used in HTML files, this should work on ReadTheDocs.
