Create a content fragment Programatically

[VeenaVikraman]

Hi all

   I am trying to create a content fragment programatically and I am not seeing the fragment being created in my node structure. Below is the code I compiled from different sources over the internet as I couldn't find a proper working example anywhere . 

public void createContentFragment(final Resource parentRsc) {
    try (ResourceResolver resourceResolver = resourceService.getResourceResolver(CommonConstants.SERVICE_USER)) {
        Resource templateOrModelRsc = resourceResolver.getResource("/conf/demo/settings/dam/cfm/models/faq");
        if (Objects.nonNull(templateOrModelRsc)) {
            FragmentTemplate tpl = templateOrModelRsc.adaptTo(FragmentTemplate.class);
            if (Objects.nonNull(tpl)) {
                ContentFragment contentFragment = tpl.createFragment(parentRsc, "test", "A fragment description.");
                if (null != contentFragment) {
                    Iterator<ContentElement> elements = contentFragment.getElements();
                    while (elements.hasNext()) {
                        ContentElement contentElement = elements.next();
                        contentElement.setContent("value", contentElement.getContentType());
                    }
                }
                Session session = resourceResolver.adaptTo(Session.class);
                if (Objects.nonNull(session)) {
                    session.save();
                }

            }
        }
    } catch (Exception e) {
        LOGGER.error("Exception ", e);
    }
}

Update :- Thanks @shubhanshu_singh  for the correct answer. Anyone facing a similar issue , please also refer my response https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/create-a-content-fragment-... , to understand what went wrong in my case.

@VeenaVikraman Code constant states "CommonConstants.READ_SERVICE_USER", does this service user has create permission under that parentRsc node?

Thanks @Saravanan_Dharmaraj  My bad. I frgot to rename that service user since I was trying hard get this working. Yes that user has write perimissions for now. Also , I made sure that I am getting the CF objects after creation. But after saving , I should see the CF node in the repository under the given path right ? I am not seeing that . I am not sure if I am doing something wrong in the commit part or is there something more expected to be done before I save the changes.

I have updated the original question.

Hi @VeenaVikraman , Below code seems to be working fine for me kindly check this

public void createContentFragment(final String parentPath, final String templatePath, ResourceResolver resourceResolver) {
Resource parent = resourceResolver.getResource(parentPath);
Resource template = resourceResolver.getResource(templatePath);

ContentFragment fragCreated = null;
try {

FragmentTemplate model = template.adaptTo(FragmentTemplate.class);
fragCreated = model.createFragment(parent, "name", "title");
fragCreated.setDescription("Test Description");
Resource fragRsc = fragCreated.adaptTo(Resource.class);
ResourceResolver resolver = fragRsc.getResourceResolver();
resolver.commit();

} catch (Exception e) {
log.error("Exception {}", e);
}
}

Super awesome @shubhanshu_singh . Your answer is perfectly correct. And the culprit in my case was the resolver I was using for commit. I tried commiting the changes like below. 

1. Using ResourceResolver I got for my system user 

try (ResourceResolver resourceResolver = 
resourceService.getResourceResolver(CommonConstants.SERVICE_USER)) {
  .........
    
            resourceResolver.commit();
........
}

2. Using Session I got from the Resource Resolver 

try (ResourceResolver resourceResolver 
= resourceService.getResourceResolver(CommonConstants.SERVICE_USER)) {
   ........
            Session session = resourceResolver.adaptTo(Session.class);
            LOGGER.info("TPL is {}", session);
            session.save();
......
}

But both didn't work. The one that works is the one which @shubhanshu_singh mentioned above 

Get the resourceResolver from the contentFragment's Resource and use it to commit.

Resource fragRsc = contentFragment.adaptTo(Resource.class);
if (Objects.nonNull(fragRsc)) {
    ResourceResolver resolver = fragRsc.getResourceResolver();
    resolver.commit();
}

And this only one changed actually helped
