Hi,

I have a custom dropdown in page properties Basic Tab, This dropdown show while creating new page. I want take the current selected page and get values from OSGi service to show the drop.

How I can get the current page path in datasource sling model?

Below is my code.

1. DatasourceModel.java

@Model(adaptables = SlingHttpServletRequest.class)
public class DatasourceModel {

    private static final Logger LOG = LoggerFactory.getLogger(DatasourceModel.class);

    @Self
    protected SlingHttpServletRequest request;

    @586265
    @required
    @SlingObject
    private ResourceResolver resourceResolver;

    @PostConstruct
    public void init(){
        // get List of values from OSGi service by passing current page(parent page) path
        ValueMap valueMap = new ValueMapDecorator(new HashMap<>());
        valueMap.put("text", "textOne");
        valueMap.put("value", "valueOne");
        List<Resource> resourceList = new ArrayList<>();
        resourceList.add(new ValueMapResource(resourceResolver,
                new ResourceMetadata(), "nt:unstructured", valueMap));
        DataSource ds = new SimpleDataSource(resourceList.iterator());
        request.setAttribute(DataSource.class.getName(),ds);
    }

}

2. datasource.html

<sly data-sly-use="com.mysite.core.models.DatasourceModel"/>

3. dialog.xml

Hi @codingstar

You can try below snippet to get current page path in the java class.

String requestPagePath = StringUtils.EMPTY;
String pagePath = StringUtils.EMPTY;
Enumeration<String> values = request.getHeaders("Referer");
if (values != null){
    while (values.hasMoreElements()) {
        requestPagePath= values.nextElement();
    }
}

// to get current page path while creating a new page
if (requestPagePath.contains("createpagewizard.html/")) {
    pagePath = requestPagePath.split("createpagewizard.html")[1];
}

// to get current page path while opening properties of existing page
RequestParameter resourceParameter = request.getRequestParameter("item");
if(resourceParameter != null && StringUtils.isNotEmpty(resourceParameter.getString())) {
    pagePath = resourceParameter.getString();
}

Use below approach to have dynamic dialog dropdown using datasource using servlet.

This should be path of servlet -> sling:resourceType="/apps/mysite/components/datasource"

Hi @codingstar

To get the current page path in your `DatasourceModel.java` class, you can use the `Resource` object available in the `SlingHttpServletRequest` object. You can get the current page's `Resource` object using the `getResource()` method of the `SlingHttpServletRequest` object. Once you have the `Resource` object, you can get its path using the `getPath()` method.

---------------------
@Model(adaptables = SlingHttpServletRequest.class)
public class DatasourceModel {

private static final Logger LOG = LoggerFactory.getLogger(DatasourceModel.class);

@Self
protected SlingHttpServletRequest request;

@Inject
@Required
@SlingObject
private ResourceResolver resourceResolver;

@PostConstruct
public void init(){
// get current page path
Resource resource = request.getResource();
String currentPagePath = resource.getPath();

// get List of values from OSGi service by passing current page(parent page) path
ValueMap valueMap = new ValueMapDecorator(new HashMap<>());
valueMap.put("text", "textOne");
valueMap.put("value", "valueOne");
List<Resource> resourceList = new ArrayList<>();
resourceList.add(new ValueMapResource(resourceResolver,
new ResourceMetadata(), "nt:unstructured", valueMap));
DataSource ds = new SimpleDataSource(resourceList.iterator());
request.setAttribute(DataSource.class.getName(),ds);
}

}

Hi @codingstar

you can get the curent page path from the URL.

example : if you decode item query parem you will get the page path

http://localhost:4502/mnt/overlay/wcm/core/content/sites/properties.html?item=%2Fcontent%2Fwknd%2Flanguage-masters
