test condition for model class

Hi,

I have a query, can we write a condition to check the methods in the model class before we call the model class using data-sly-use and call the methods.

 

here's a scenario:

Model Class,

 

@Model(adaptables = Resource.class)
public class HelloWorldModel {

    @ValueMapValue(name=PROPERTY_RESOURCE_TYPE, injectionStrategy=InjectionStrategy.OPTIONAL)
    @1497330(values="No resourceType")
    protected String resourceType;
    @586265
    private String message;
    public String getHelloMessage() {
        return message;
    }
}

 

HTML file

 

<div data-sly-use.model="com.bootcamp.core.models.HelloWorldModel">
 
data-message=${model.helloMessage} </div>
question: how do I use data-sly-test to check the class and it's objects
 
Thanks,

<section data-sly-use.model="com.bootcamp.core.models.HelloWorldModel" data-

message="${model.helloMessage}">

</section>

This is just fine, looks like you are using HTML attributes, which is consumed by the JS frontend code. you can detect whether data-message is null, blank or not, then perform the task as needed.

Easy,
<sly data-sly-use.model="com.bootcamp.core.models.HelloWorldModel"></sly>
<sly data-sly-test="${model.helloMessage}>${helloMessage}</sly>

    This is helpful Brian, could you suggest me for a different secnario.

     

    here's the scenario: take the example of the same model class above,

     

    <section data-sly-use.model="com.bootcamp.core.models.HelloWorldModel" data-

    message="${model.helloMessage}">

    </section>

    How do I write a test condition as an attribute for the section tag and execute the helloMessage method.

     

    Thanks,

        @vinod-n-e it's recommended to write your logic on the sling model and assign a return value to a member variable and use that in HTL.

            @vinod-n-e I believe, data-sly-use initializes your sling model, ie. it basically declares component-beans with this statement for instance, to check conditions before that may not be possible. 

            However, I am not sure what your use case is.
