Liferay Segments Criteria Extension Sample

Liferay Segments Criteria Extension Sample

Code for Liferay's /dev/24 talk:

How to create your own segments criteria

• Short introduction to Segmentation and Personalization
• Personalization in Action!
• Creating complex segments:
  • User & Organization criteria: fields and custom fields
  • Session criteria: session properties, request attributes, cookies, etc
  • Segments criteria: segments as criterion. Introduced in 7.3.
• Hands-on Creating a Segment Criteria Contributor

This repo will guide you step-by-step on how to extend the Liferay Segments Criteria capabilities by creating your own Segment Criteria Contributor. As an example we'll create a contributor that segments users based on the Knowledge Base articles they have authored.

Steps

1. Make your related entity (KBArticle) searchable through OData queries:
   • EntityModel: represents your associated entity with its fields of interest.
   • ODataRetriever: obtains the KBArticles that match a given OData query.
2. Customize fields of type ID to use an entity selector:
   • ItemSelector: Provides a KBArticles selector.
   • SegmentsFieldCustomizer: Connects the ID field with the ItemSelector and provides a meaningful field value name.
3. Create the SegmentsCriteriaContributor: It contributes a query to filters users based on the articles they authored.

Follow the commits for a step by step explanation.

How to run it

Clone the repo and run the following:

LIFERAY_HOME=<your liferay home folder> ./gradlew deploy

In my case:

LIFERAY_HOME=~/projects/liferay/portal/bundles ./gradlew deploy ./gradlew deploy
