Plone tag navigation
folderish navigation is often useless, because most pages have different places where they fit. A simple navigation by keywords (tags) is a soloution for small sites
Introduction
I just have a small site and I don't want to create a tree navigation, because it's useless and confuses the visitor.
The file (if it is a singe page) or the folder (for multi-page content) get's some keywords and from the keywords I generate a navigation list.
The sourcecode is really simple. first of all, there is a python script:
## Script (Python) "keywords"
##bind container=container
##bind context=context
##bind namespace=
##bind script=script
##bind subpath=traverse_subpath
##parameters=
##title=
##
# Import a standard function, and get the HTML request and response objects.
from Products.PythonScripts.standard import html_quote
request = container.REQUEST
RESPONSE = request.RESPONSE
keywords = list(context.portal_catalog.uniqueValuesFor('Subject'));
keywords.sort( lambda y,x: cmp(x,y) )
keywords.reverse()
hmap = []
url = ""
for keyword in keywords:
results = context.portal_catalog(Subject=keyword)
length = len(results)
if length == 1:
url = results[0].getURL
if length > 0:
hmap.append(
{'keyword': keyword,
'size': length,
'url': url}
)
return hmap
This script returns a hashmap with all the keywords, a counter and a url (if there is just one hit, you can directly link to the url.
A portlet shows the results:
<html xmlns:tal="http://xml.zope.org/namespaces/tal"
xmlns:metal="http://xml.zope.org/namespaces/metal"
i18n:domain="plone">
<body>
<div metal:define-macro="portlet">
<dl class="portlet"
id="portlet-keywords"
tal:define="catalogSubjects here/keywords;">
<dt class="portletHeader">
<span i18n:translate="box_keywords">Keywords</span>
</dt>
<dd class="portletItem odd"
tal:repeat="subject catalogSubjects"
i18n:domain="plone-metadata"
i18n:translate=""
>
<a tal:define="link string:search?SearchableText=${subject/keyword}"
tal:attributes="href link" tal:content="string:${subject/keyword} (${subject/size})">dummy</a>
</dd>
</dl>
</div>
</body>
</html>
ToDo:
- improve the css
- add direct URL Link
