[jira] [Commented] (SLING-3516) Sling Models Resource Child List Injector

["Konrad Windszus (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-3516?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13993695#comment-13993695 ] 

Konrad Windszus commented on SLING-3516:
----------------------------------------

I would rather go for a separate injector, which also supports some kind of filtering expression (a regexp) against the child node names, to only adapt some of the children (and leave out others).
Your approach is different from the regular ResourceChild injector, because it does not consider the name at all. I think using a separate injector is the cleaner approach here.

> Hi All,
> We have decided to use the sling models to process some hierarchical data in our project and are facing the following issue right now.
> Our content structure looks as follows:
> {code}
> +- dealer
>   |
>   +- addresses
>      |
>      + -address1
>      |
>      +- address2
> {code}
> Dealer and address nodes have attributes, that can be injected through the ValueMapInjector, so everything works fine here. Our goal however is also to inject the List of AddressModel objects into the DealerModel object, something like this:
> {code}
> @Inject
> List<AddressModel> addresses
> {code}
> The desired behavior would be:
> - the injector resolves addresses as a child resource of the adaptable object
> - iterates over the children of this resource (in this case „addresses")
> - adapts each child to the actual type argument of the parameterized list type
> - returns the list of adapted model objects
> I have tried to play around with @Named but could not get it to work. The only way of making it work, was to write a custom injector, which worked out pretty fine. 
> But I was still wondering, if there might be an OOTB functionality, which can be used for this use case
> Cheers, Igor.
