SlingHttpServletRequest adapto custom sling model

Hi There ,

 I'm using a custom sling model which i have annotated to be adapto from resource and singHttpServletRequest .

I have designed my model with the fields same as in my form ,

Example : My form has fields "Name", "Age," "Address"

my model also has these 3 fields all injected using "

@Inject @Named (field name from form)

"

I was assuming doing this would automatically map my request parameters to sling model if i perform request.adapto(customodel.class) .However this doesn't seem to work .

Is my understanding right in doing this ? Did i miss anything here ?

 

regards

    Hi Kris,

     

    You could use the RequestAttribute[1] annotation that has been created for your use case.

    [1] http://grepcode.com/file/repo1.maven.org/maven2/org.apache.sling/org.apache.sling.models.api/1.2.0/org/apache/sling/models/annotations/injectorspecific/RequestAttribute.java#RequestAttribute

     

    Regars,

    Peter

    Once you have adapted your resource to slinghttprequest in sling model

    All you need to do is using below code to get properties saved in node

    ValueMap node = request.getResource().getValueMap();
    String path = node.get("text", String.class);

    Here I am retrieving 'text' property

    Do see this article to get more idea:

    Thanks for the reply. 

    But this approach is leading me to the impression that I need to manually map request Params to custom mode by get and set. 

    I had already used annotations to map req Params to sling model shouldn't be performing it manually again. Spring requestdatabinder does exactly this. Waiting for the same in sling
