Create a content fragment Programatically

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);
    }
}

    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 @shubhanshusi2 . 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 @shubhanshusi2 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

        @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.
