lineage.index 0.1b1

Adds an index and metadata that allows to search for content of a collective.lineage childsite

Introduction

lineage.index is an addon to collective.lineage that let’s you search for content within a certain childsite.

Caution!

lineage.index requires collective.lineage 0.2 or newer because it depends on the IChildSite interface.

Currently there is no egg release for 0.2, hopefully this will change soon.

How does it do it?

lineage.index registers an index childsite on all items implementing IATContentType.

The childsite’s id can be used to search for content located in this childsite.

When listing items on the mainportal you can use the metadata-column childsite to indicate which childsites the content has been aggregated from.

How do I use it?

Once installed, new content get’s indexed under the id of it’s closest childsite. Existing content requires a catalog update (see Installation).

You can search for content within a childsite using the index:

brains = portal_catalog(childsite='subsite1')

Each brain has a metadata column telling which childsite it’s located in:

>>> brain.childsite
'subsite1'

There’s also a vocabulary lineage.childsites listing the available childsites with their title.

To show the title of the subsite of a brain you can use the utility view:

<ul tal:define="util context/@@childsite">
    <li tal:repeat="item folderContents">
        <span tal:replace="item/Title">Item 1</span> in
        <span tal:replace="python: util.titleForKey(item.childsite)>Subportal One</span>
    </li>
</ul>

Installation

Simply add lineage.index to your buildout eggs (no zcml slug is needed thanks to z3c.autoinclude).

Quickinstall Lineage Index.

In case you already have childsites and content that shall be indexed go to portal_catalog/manage_catalogAdvanced and click the Update Catalog button to populate the index and the catalog metadata.

Gotchas

The vocabulary caches all childsite titels until zope is restarted. If you add childsites you need to restart zope to make them show up in the vocabulary
