HTL Request Attributes with sly-include and sly-resource

By Arjun Menon··1 min read

With data-sly-include and data-sly-resource you can pass requestAttributes, which the receiving HTL script can then read and process.

<sly data-sly-use.settings="com.adobe.examples.htl.core.hashmap.Settings"
     data-sly-include="${ 'productdetails.html' @ requestAttributes=settings.settings}" />

The requestAttributes map can come from a Java class:

public class Settings extends WCMUsePojo {

    // passed as requestAttributes to data-sly-include / data-sly-resource
    public Map<String, Object> settings = new HashMap<String, Object>();

    @Override
    public void activate() throws Exception {
        settings.put("order", "ascending");
    }
}

Reading request attributes in a Sling Model

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

    @Inject @Optional @Default(values="empty")
    public String order;
}

Here order is injected from the map set by the Use class.
