content node property updates

[SreenivasuluPu]

Hi,

I have a Content Fragment Model and content fragments created with content fragment model.

Now the team wants to move Content Fragment Model from "/conf/projectA/CustomModels/settings/CF-model" to "/conf/projectA/settings/CF-model".

Use case: Existing content fragments referencing "/conf/projectA/CustomModels/settings/CF-model" at /content/dam/cf1/data/@cq:model, /content/dam/cf1/idexedData/master/@string@model properties.

What is the best way to update above property values to point to new Content Fragment Model Path "/conf/projectA/settings/CF-model".

I appreciate all the help.

AEM 6.5.17 is version.

Thanks,

Sri

Hi @SreenivasuluPu 

1. Create a backup: Before making any changes, it's always a good practice to create a backup of your content in case anything goes wrong during the update process.

2. Update the Content Fragment Model path: Move the Content Fragment Model from "/conf/projectA/CustomModels/settings/CF-model" to "/conf/projectA/settings/CF-model". You can do this by using the AEM Web Console or the CRXDE Lite.

3. Update the property values: To update the property values of the existing content fragments, you can use the AEM Query Builder or a custom script. Here's an example of how you can use the AEM Query Builder to update the property values:

- Open the AEM Query Builder console (`/libs/cq/search/content/querydebug.html`).
- Enter the following query in the "Query" field:
path:/content/dam/cf1
Replace `/content/dam/cf1` with the actual path of your content fragments.
- Click on the "Execute Query" button to execute the query.
- Select the content fragments that need to be updated.
- Click on the "Edit Properties" button.
- Update the property values to point to the new Content Fragment Model path ("/conf/projectA/settings/CF-model").
- Save the changes.

4. Verify the updates: After updating the property values, verify that the content fragments now reference the new Content Fragment Model path ("/conf/projectA/settings/CF-model").

Hi @SreenivasuluPu ,

To update the property values referencing the old Content Fragment Model path to the new path in Adobe Experience Manager (AEM) 6.5.17 using Java code, you can follow these steps:

1. Backup Content: Before making any changes, it's essential to create a backup of your content to avoid accidental data loss.

2. Iterate Over Content Fragments: Write a Java code to iterate over the content fragments and update the properties referencing the old Content Fragment Model path to the new path.

3. Update Properties: For each content fragment, check if the properties cq:model and model exist and if they contain the old path. If so, update them with the new path.

4. Save Changes: After updating the properties, save the changes to the JCR repository.

Here's a sample Java code snippet to achieve this:

import javax.jcr.Node;
import javax.jcr.RepositoryException;
import javax.jcr.Session;
import javax.jcr.NodeIterator;

import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.resource.ResourceResolverFactory;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Reference;

@Component(service = YourService.class)
public class YourService {

    @Reference
    private ResourceResolverFactory resolverFactory;

    public void updateContentFragmentModels() {
        // Define the old and new paths
        String oldModelPath = "/conf/projectA/CustomModels/settings/CF-model";
        String newModelPath = "/conf/projectA/settings/CF-model";

        try (ResourceResolver resolver = resolverFactory.getServiceResourceResolver(null)) {
            Session session = resolver.adaptTo(Session.class);
            if (session != null) {
                // Start the traversal from the root node where content fragments are stored
                Node rootNode = session.getNode("/content/dam");

                // Traverse content fragments
                traverseAndUpdate(rootNode, oldModelPath, newModelPath);

                // Save the changes
                session.save();
            }
        } catch (RepositoryException e) {
            // Handle exception
        }
    }

    private void traverseAndUpdate(Node node, String oldModelPath, String newModelPath) throws RepositoryException {
        if (node.hasProperty("cq:model")) {
            String modelPath = node.getProperty("cq:model").getString();
            if (modelPath.equals(oldModelPath)) {
                // Update the property value
                node.setProperty("cq:model", newModelPath);
            }
        }

        if (node.hasProperty("model")) {
            String modelPath = node.getProperty("model").getString();
            if (modelPath.equals(oldModelPath)) {
                // Update the property value
                node.setProperty("model", newModelPath);
            }
        }

        // Recursively process child nodes
        NodeIterator iterator = node.getNodes();
        while (iterator.hasNext()) {
            Node childNode = iterator.nextNode();
            traverseAndUpdate(childNode, oldModelPath, newModelPath);
        }
    }
}

This code assumes you have an OSGi service to execute the updates. Adjust the paths and error handling as needed for your specific requirements and environment.
