Hello all, 

I have created a component which should accept only page path through cq:dialog. When I select the page and click submit through dialog then it should print all the page properties like title, description& image or image url . Is it possible ??

 Here is my component dialog:

1. Page path field in Component touch ui dialog editor -

2. Sling model -

package com.aem.demo.core.models;

import java.util.Map;

import javax.annotation.PostConstruct;

import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.resource.ValueMap;
import org.apache.sling.models.annotations.DefaultInjectionStrategy;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.models.annotations.injectorspecific.SlingObject;
import org.apache.sling.models.annotations.injectorspecific.ValueMapValue;

import com.day.cq.wcm.api.Page;
import com.day.cq.wcm.api.PageManager;


@Model(adaptables = Resource.class , defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class PagePropertydetailModel {

	@ValueMapValue
	private String pagepath;
	
	@SlingObject
    private ResourceResolver resourceResolver;
	
	private Map<String,Object> pageProperties;
	
	@PostConstruct
	protected void init() {
		
		
		PageManager pageManager = resourceResolver.adaptTo(PageManager.class);
		Page page = pageManager.getPage(pagepath);
		pageProperties = page.getProperties();
		
		
		
		
		
	}

	public Map<String, Object> getPageProperties() {
		return pageProperties;
	}
}

3. Htl code -

Page Information</br>

<div data-sly-use.map="com.aem.demo.core.models.PagePropertydetailModel">

  <sly data-sly-list="${map.pageProperties.keySet.iterator}">

     <li>key = ${item}</li>    
      ${map.pageProperties[item]}


   </sly>

</div>

Just shared the idea. I will update logic for Date field like jcr:created and cq:lastModified

You can write a sling model for custom component. Using resource resolver you can get resource and adapt to Page. Once you adaptTo Page, you can iterate all properties. Please refer below links for more details.

@Tessa_learner1 Yes its possible to do in the sling model.

 

@Model(adaptable=Resource.class)

public class TestClass {

@Self

Resource resource;

@PostConstruct

public void init() {

  PageManager pm = resource.getResourceResolver().adaptTo(PageManager.class);

  Page containingPage = pm.getContainingPage (resource);

  ValueMap pageProperties = containingPage.getProperties();

}

}

 

map the properties to variables and then use it in the HTL.
