This CKAN Extension demonstrates some common patterns for customising a CKAN instance.
It comprises:
* A CKAN Extension "plugin" at ``ckanext/exampletheme/__init__.py``
which, when loaded, overrides various settings in the core
``ini``-file to provide:
* A path to local customisations of the core templates and stylesheets
* A "stream filter" that replaces arbitrary strings in rendered templates
* A "route" to override and extend the default behaviour of a core CKAN page
* A custom Pylons controller for overriding some core CKAN behaviour
* A custom Package edit form
* Some simple template customisations
Installation
============
To install this package, from your CKAN virtualenv, run the following from your CKAN base folder (e.g. ``pyenv/``)::
pip install -e hg+https://bitbucket.org/okfn/ckanext-exampletheme#egg=ckanext-exampletheme
Then activate it by setting ``ckan.plugins = exampletheme`` in your main ``ini``-file.
Orientation
===========
* Examine the source code, starting with ``ckanext/exampletheme/__init__.py``
* To understand the nuts and bolts of this file, which is a CKAN
*Extension*, read in conjunction with the "Extension
documentation":http://packages.python.org/ckan/plugins.html
* One thing the extension does is set the values of
``extra_public_paths`` and ``extra_template_paths`` in the CKAN
config, which are "documented
here":http://packages.python.org/ckan/configuration.html#extra-template-paths
* These are set to point at directories within
`ckanext/exampletheme/theme/`` (in this package). Here, we override
the home page, provide some extra style with an ``extra.css``, and
customise the navigation and header of the main template in the file ``layout.html``.
The latter file is a great place to make global theme alterations.
It uses the _layout template_ pattern "described in the Genshi
documentation":http://genshi.edgewall.org/wiki/GenshiTutorial#AddingaLayoutTemplate.
This allows you to use Xpath selectors to override snippets of HTML
globally.
* The custom package edit form at ``package_form.py`` follows the
conventions in the "main CKAN
documentation":http://packages.python.org/ckan/forms.html
