Get asset path for overlayed component.

[subsul1]

I've overlayed the download button in the modal pop-up shown below. This modal is displayed when user tries to download an asset.

My intention is to display the blue download button based on a metadata property in the asset and granite:renderconditions.

Download modal

Overlay node: /libs/dam/gui/content/assets/downloadasset/footer/download

Overlayed code in /apps:

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:granite="http://www.adobe.com/jcr/granite/1.0" xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0"

            <download jcr:primaryType="nt:unstructured">
                <granite:rendercondition
                    jcr:primaryType="nt:unstructured"
                    sling:resourceType="granite/ui/components/coral/foundation/renderconditions/and">
                    <not
                        jcr:primaryType="nt:unstructured"
                        sling:resourceType="granite/ui/components/coral/foundation/renderconditions/not">
                        <containsProp
                            jcr:primaryType="nt:unstructured"
                            path="${requestPathInfo.suffix}"
                            sling:resourceType="temp-prj/components/render-conditions/contains-prop"/>
                    </not>
                </granite:rendercondition>
            </download>
        </footer>
    </downloadasset>
</jcr:root>

contains-prop.jsp :

<%@page session="false" import="com.adobe.granite.ui.components.Config,
                                    com.day.cq.wcm.api.Page,
                                    org.apache.sling.api.resource.Resource,
                                    com.adobe.granite.ui.components.rendercondition.RenderCondition,
                                    com.adobe.granite.ui.components.rendercondition.SimpleRenderCondition" %><%
%><%@include file="/libs/granite/ui/global.jsp" %><%
    boolean containsProp = false;

    Config cfg = cmp.getConfig();
    String path = cmp.getExpressionHelper().getString(cfg.get("path", ""));
    System.out.println("Resource path: " + path);
    
    if (path != null) {
        Resource resource = slingRequest.getResourceResolver().resolve(path);
        String rightsManaged = resource.getValueMap().get("rightsManaged", String.class);
        if(rightsManaged != null && rightsManaged.equals("proprietary")) {
            containsProp = true;
        }
    }

    request.setAttribute(RenderCondition.class.getName(), new SimpleRenderCondition(containsProp));
%>

Issue here: resource path that is getting resolved is the render:condition node and not the asset that is being downloaded

Resource path: /mnt/overlay/dam/gui/content/assets/downloadasset/footer/download/granite:rendercondition/not/isInGroup

How do I get the resource of the asset for which the download button was clicked i.e. eg /content/dam/temp-prj/temp-pic.jpeg?

Hi @subsul1, you can get list of paths for selected assets using path param that is pass as a request parameter. Please have a look on following code:

RequestParameter selectedAssets[] = slingRequest.getRequestParameters("path");
if (selectedAssets != null) {
    for (RequestParameter selectedAsset : selectedAssets) {
        String assetPath = selectedAsset.getString("UTF-8");
        System.out.println("Asset: " + assetPath);
    }
}

You should also add below into import section:

org.apache.sling.api.request.RequestParameter

Having above path(s) you will be able to retrieve all information from specific asset.

Thanks @lukaszm

This worked for me.
