Project collective.portlet.localcumulus cumulus product by Makina Corpus

Project Description

Introduction

This package provides 2 new tagcloud based portlets

With

  • cache (refresh)
  • local path searches enhancements

And for the ‘custom portlet’:

  • url customization for tag browsing

Usage

  • Install “Local Tag cloud (cumulus) portlet” with QuickInstaller.
  • Select Local Tag Cloud (cumulus) portlet from Add portlet drop-down menu.
  • Provide your own values for portlet configuration if needed.
  • Save changes.

Supported Plone version

  • 3.x

Repository:

svn

collective.portlet.cumulus Installation

To install collective.portlet.cumulus into the global Python environment (or a workingenv), using a traditional Zope 2 instance, you can do this:

  • When you’re reading this you have probably already run

    ``easy_install collective.portlet.cumulus``.
    

    Find out how to install setuptools (and EasyInstall) here: http://peak.telecommunity.com/DevCenter/EasyInstall

  • If you are using Zope 2.9 (not 2.10), get pythonproducts and install it via:

    python setup.py install --home /path/to/instance
    

    into your Zope instance.

  • Create a file called collective.portlet.cumulus-configure.zcml in the /path/to/instance/etc/package-includes directory. The file should only contain this:

    <include package="collective.portlet.cumulus" />
    

Alternatively, if you are using zc.buildout and the plone.recipe.zope2instance recipe to manage your project, you can do this:

  • Add collective.portlet.cumulus to the list of eggs to install, e.g.:

    [buildout]
    ...
    eggs =
        ...
        collective.portlet.cumulus
    
  • Tell the plone.recipe.zope2instance recipe to install a ZCML slug:

    [instance]
    recipe = plone.recipe.zope2instance
    ...
    zcml =
        collective.portlet.cumulus
    
  • Re-run buildout, e.g. with:

    $ ./bin/buildout
    

You can skip the ZCML slug if you are going to explicitly include the package from another package’s configure.zcml file.

The local renderer and portlet objects

Adding some content for testing searches

>>> self.setRoles(('Manager', ))
>>> self.portal['front-page'].edit(subject=['global', 'tags'])
>>> if1 = self.folder.invokeFactory('Folder', id='f1')
>>> if2 = self.folder.invokeFactory('Folder', id='f2')
>>> f1 = self.folder[if1]
>>> f2 = self.folder[if2]
>>> d1 = f1.invokeFactory('Document', id='blog-entry1')
>>> d2 = f1.invokeFactory('Document', id='blog-entry2')
>>> d3 = f2.invokeFactory('Document', id='blog-entry3')
>>> d4 = f2.invokeFactory('Document', id='blog-entry4')
>>> f1[d1].edit(subject=['blog', 'tags'])
>>> f1[d2].edit(subject=['foo', 'bar'])
>>> f2[d3].edit(subject=['toto', 'titi'])
>>> f2[d4].edit(subject=['toto', 'tutu'])

Looking for our adapter to be in place

>>> from collective.portlet.localcumulus.interfaces import ILocalTagsRetriever
>>> from collective.portlet.localcumulus import catalog
>>> data = catalog.DummyData()
>>> data.refreshInterval = 1

This adapter takes a context and an Assigment as ‘data’ attribute

>>> retriever = ILocalTagsRetriever(f1)
>>> retriever
<collective.portlet.localcumulus.catalog.LocalTags object at ...>

Trying to get the local tags of the f1 folder

>>> data.path = '/'.join(f1.getPhysicalPath())
>>> retriever.data = data
>>> print '\n'.join(['%s %s %s'% i for i in retriever.getTags()])
blog 1 http://nohost/plone/search?path=/plone/Members/test_user_1_/f1&Subject:list=blog
foo 1 http://nohost/plone/search?path=/plone/Members/test_user_1_/f1&Subject:list=foo
bar 1 http://nohost/plone/search?path=/plone/Members/test_user_1_/f1&Subject:list=bar
tags 1 http://nohost/plone/search?path=/plone/Members/test_user_1_/f1&Subject:list=tags

Trying to get the local tags of the f2 folder

>>> data.path = '/'.join(f2.getPhysicalPath())
>>> print '\n'.join(['%s %s %s'% i for i in retriever.getTags()])
tutu 1 http://nohost/plone/search?path=/plone/Members/test_user_1_/f2&Subject:list=tutu
titi 1 http://nohost/plone/search?path=/plone/Members/test_user_1_/f2&Subject:list=titi
toto 2 http://nohost/plone/search?path=/plone/Members/test_user_1_/f2&Subject:list=toto

If we have a portlet without path, it goes system wide

>>> data.path = ''
>>> print '\n'.join(['%s %s %s'% i for i in retriever.getTags(data=data)])
bar 1 http://nohost/plone/search?Subject:list=bar
blog 1 http://nohost/plone/search?Subject:list=blog
foo 1 http://nohost/plone/search?Subject:list=foo
global 1 http://nohost/plone/search?Subject:list=global
tags 2 http://nohost/plone/search?Subject:list=tags
titi 1 http://nohost/plone/search?Subject:list=titi
toto 2 http://nohost/plone/search?Subject:list=toto
tutu 1 http://nohost/plone/search?Subject:list=tutu

Testing cache

>>> import time
>>> data.path = '/'.join(f2.getPhysicalPath())
>>> data.refreshInterval = 10
>>> [o[0] for o in retriever.getTags()]
[u'tutu', u'titi', u'toto']
>>> f2[d4].edit(subject=['toto', 'tutu', 'tata'])
>>> [o[0] for o in retriever.getTags()]
[u'tutu', u'titi', u'toto']
>>> time.sleep(2)
>>> [o[0] for o in retriever.getTags()]
[u'tutu', u'titi', u'toto']

After 11 seconds, cache life is up

>>> time.sleep(9)
>>> [o[0] for o in retriever.getTags()]
[u'tutu', u'titi', u'toto', u'tata']

The local custom portlet

The custom portlet enables the user to format the url used to browse a tag instead to use the plone search_form as a default.

Tests

Adding some content for testing searches

>>> self.setRoles(('Manager', ))
>>> self.portal['front-page'].edit(subject=['global', 'tags'])
>>> if1 = self.folder.invokeFactory('Folder', id='f1')
>>> if2 = self.folder.invokeFactory('Folder', id='f2')
>>> f1 = self.folder[if1]
>>> f2 = self.folder[if2]
>>> d1 = f1.invokeFactory('Document', id='blog-entry1')
>>> d2 = f1.invokeFactory('Document', id='blog-entry2')
>>> d3 = f2.invokeFactory('Document', id='blog-entry3')
>>> d4 = f2.invokeFactory('Document', id='blog-entry4')
>>> f1[d1].edit(subject=['blog', 'tags'])
>>> f1[d2].edit(subject=['foo', 'bar'])
>>> f2[d3].edit(subject=['toto', 'titi'])
>>> f2[d4].edit(subject=['toto', 'tutu'])

Looking for our adapter to be in place

>>> from collective.portlet.localcumulus.interfaces import ICustomLocalTagsRetriever
>>> from collective.portlet.localcumulus import catalog
>>> data = catalog.DummyData()
>>> data.refreshInterval = 1
>>> data.path = '/'.join(f1.getPhysicalPath())

This adapter takes a context and an Assigment as ‘data’ attribute

>>> retriever = ICustomLocalTagsRetriever(f1)
>>> retriever
<collective.portlet.localcumulus.catalog.CustomLocalTags object at ...>

Trying to get the local tags of the f1 folder with no url, it will default to the localtag behaviour

>>> data.search_url = ''
>>> retriever.data = data
>>> print '\n'.join(['%s %s %s'% i for i in retriever.getTags()])
blog 1 http://nohost/plone/search?path=/plone/Members/test_user_1_/f1&Subject:list=blog
foo 1 http://nohost/plone/search?path=/plone/Members/test_user_1_/f1&Subject:list=foo
bar 1 http://nohost/plone/search?path=/plone/Members/test_user_1_/f1&Subject:list=bar
tags 1 http://nohost/plone/search?path=/plone/Members/test_user_1_/f1&Subject:list=tags

Customize url with variables

We can play with some variables in python dict-string formating style.

If we have an url without any parameters inside, it just appends the tag at the end

>>> [bool(catalog.NOT_SIMPLE_URL_RE.match(a)) for a in ['azerty', '()', '%(azerty)s', '%()', '%()s']]
[False, False, True, False, False]
>>> data.search_url = 'http://foo'
>>> retriever.data = data
>>> print '\n'.join(['%s' % i for i in retriever.getTags()])
[u'blog', 1, u'http://foo/blog&path=/plone/Members/test_user_1_/f1']
[u'foo', 1, u'http://foo/foo&path=/plone/Members/test_user_1_/f1']
[u'bar', 1, u'http://foo/bar&path=/plone/Members/test_user_1_/f1']
[u'tags', 1, u'http://foo/tags&path=/plone/Members/test_user_1_/f1']

Think that you’ll surely have to add at least %(tag)s somewhere in your url to include the tag information ;).

Variables avaiblable are:

  • portal_path: plone site path
  • portal_url: plone site url
  • here_url: context url
  • here_path: context path inside the ZODB
  • tag: the tag
  • tag_weight: weight of the tag
>>> data.search_url = '%(portal_url)s?path=%(portal_path)s&url=%(here_url)s&hpath=%(here_path)s&tag=%(tag)s&weight=%(tag_weight)s'
>>> retriever.data = data
>>> print '\n'.join(['%s' % i for i in retriever.getTags()])
[u'blog', 1, u'http://nohost/plone?path=/plone&url=http://nohost/plone/Members/test_user_1_/f1&hpath=/plone&tag=blog&weight=1']
[u'foo', 1, u'http://nohost/plone?path=/plone&url=http://nohost/plone/Members/test_user_1_/f1&hpath=/plone&tag=foo&weight=1']
[u'bar', 1, u'http://nohost/plone?path=/plone&url=http://nohost/plone/Members/test_user_1_/f1&hpath=/plone&tag=bar&weight=1']
[u'tags', 1, u'http://nohost/plone?path=/plone&url=http://nohost/plone/Members/test_user_1_/f1&hpath=/plone&tag=tags&weight=1']
