Fetch Content Fragment using Sling Model

We have seen how to create a content fragment in the previous post.

Content Fragments can be rendered onto a page by below different ways:
  1. Using AEM core components
  2. Using Custom Sling Model
  3. Using Servlet to access Content Fragment.

Fetch Content Fragment using AEM Core Components

We have seen how to create a content fragment in the previous post.

Content Fragments can be rendered onto a page by below different ways:
  1. Using AEM core components
  2. Using Custom Sling Model
  3. Using Servlet to access Content Fragment.

Let's see how to render Content Fragment using AEM Core Components.

Enable AEM core components

Create a new project called “aemquickstart” using Adobe’s project archetype. Below is a maven archetype command to use. This will generate a boilerplate project with the latest version of Core Components.
mvn -B archetype:generate 
 -D archetypeGroupId=com.adobe.granite.archetypes 
 -D archetypeArtifactId=aem-project-archetype 
 -D archetypeVersion=23 
 -D aemVersion=cloud 
 -D appTitle="AEM Quickstart" 
 -D appId="aemquickstart" 
 -D groupId="com.aemquickstart" 
 -D frontendModule=general 
 -D includeExamples=n

Run below maven command to install the package in AEM
mvn clean install -PautoInstallPackage

Content fragment and content fragment list core components under ui.apps sub module
  • /aemquickstart/ui.apps/src/main/content/jcr_root/apps/aemquickstart/components/content/contentfragment
  • /aemquickstart/ui.apps/src/main/content/jcr_root/apps/aemquickstart/components/content/contentfragmentlist

Let's add these components on to the page.
  1. Go to AEM Start > Sites > aemquickstart > US > English
  2. Click on the parsys
  3. Click the plus icon
  4. Select Content Fragment
  5. Edit the content fragment
  6. Select the "AEM Book" content fragment that we created in the previous post
  7. Add Title, Description, Release Date and Image elements as shown below.
  8. Save the dialog

Now we can see the content fragment info on the page.

What is Content Fragment?

Content Fragments are editorial content, primarily text, and related images. They are pure content, without design and layout. Content fragments are not available in the classic UI. AEM also supports the translation of fragment content. Learn more about content fragments here.

Create Content Fragment Model Configuration:

Before we create content fragment we need to create a content fragment model. AEM configurations allow you to do many things such as editable templates, contextual site configurations, and content fragment configurations.
  1. Go to AEM Start > Tools > General > Configuration Browser > Create
  2. Enter “AEM Quickstart Site” for the title
  3. Check the “Content Fragment Models” checkbox
  4. Click create

Create a DAM Folder

Content fragments are stored in the AEM DAM and are simply treated as an asset like an image or pdf. We will want to create a DAM folder for storing all of our content fragments.
  1. Go to AEM Start > Assets > Files > Create > Folder
  2. Enter the title
  3. Click create

Update Content using Launches in AEM

Launches in AEM enable you to efficiently develop content for a future release. A launch is created to allow you to make content changes for future publication (while maintaining current pages). After editing the launch page, you need to promote the Launch. So the edited launch page will be published on the live date.

For example, you have an online store and you need to display promotional info x-mas and New Year. To do this, you can create a launch page and set it to publish on 25th Dec. Create another launch page for New Year.

Creating a Launch:

Launch can be created from two consoles in AEM
  1. From Navigation -> Sites -> Create button ->Launch 
  2. From Tools -> Sites -> Launch
Navigate to Sites, create a Launch
