How to pass parameters to Sling Modal from Sightly Component

@Model({adaptables=Resource.class, adaptables=SlingHttpServletRequest.class}).

I was trying to pass some parameters/values from my sighlty html to my sling model, once we receive those parameters in our java we have some custom process requirement for those parameters and have to return some value found in repository to sighlty.

You can try the adaptables way. Another way is we can change our approach from sling model to wcmuse pojo way for this component alone.

Sighlty code snippet for passing some parameters (Those parameters are not authored by the author) from sightly component to Java/WCMUsePojo class

<sly data-sly-use.customPropReader="${'com.yourcompany.division.project.CustomPropReader' @ properties='prop1,prop2'}"></sly>

WCM use pojo Java code to read those parameters.

public class CustomPropReader extends WCMUsePojo {

/**

* custom biz logic applied value map

*/

private HashMap customProcessedProps;

@Override

public void activate() {

String property = get("properties", String.class) != null ? get("properties", String.class) : "";

String[] propertyList = property.split(",");

//We will get all values in propertyList string array. We can loop through those each value and apply custom logic

//One we got the results we can send them back to Sightly

customProcessedProps = new HashMap<String, String> ();

for (String property : propertyList) {

//apply custom logic to each property string and put that in map.

customProcessedProps.put(property, applyCustomBizLogic(property));

}

}

/**

* get ValueMap of inheritedPageProperties

*

* @return HashMap

*/

public HashMap getCustomProcessedProp() {

return customProcessedProps;

}

}

Thanks.

Adobe recommends to use sling model instead of WCMUsePoJo. I was curious how to adaptable two classes in above examples.

WCMUsePojo is a valid way if you prefer to use over Sling Models,

We can do with sling models as below:

import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.models.annotations.Optional;
import org.apache.sling.models.annotations.injectorspecific.RequestAttribute;
@Model(adaptables = SlingHttpServletRequest.class)
public class TestModel {
@RequestAttribute
@Optional
private String test;
@PostConstruct
    public void init() {
        //we can read the values directly here.
    }
}

<sly data-sly-use.mySlingModal="${'TestModel' @ test='red'}"></sly>

Here is HTL and Sling models -- Adobe Experience Manager Help | Creating a HTL Repeating Data Set 6.3 Component that uses Sling Models

Using this approach - as you see - very little Java code. 

Hi,

Correction in this for the curly braces: @Model(adaptables = {Resource.class, SlingHttpServletRequest.class})
