Re: GET query parameters
Hello Stokes,
Your approach seems ok for me. Your Gadget Resource is well identified,
and you just want to customize the representation of a gadget.
Just attach your resource with the simple pattern /gadgets/{gadgetId}.
Then, in your resource, you can get the query parameters just as follow :
Form form = request.getResourceRef().getQueryAsForm();
and ask for the value of parameter includeGizmoDetail just as follow :
form.getFirstValue(includeGizmoDetail);
Best regards,
Thierry Boileau
I'm using Restlets mainly for read-only access to domain objects, which are
rendered as XML. In some cases I would like the amount of detail in the
representation to be specified in the request.
For example, if Gadgets contain Gizmos, then I have:
http://myhost.com/rest/gadgets/1234 for the details of a Gadget
http://myhost.com/rest/gadgets/1234/gizmos for the Gizmos within a Gadget
http://myhost.com/rest/gadgets/1234/gizmos/5678 for the details of a Gizmo
But in some cases, I need to fetch a Gadget with all its Gizmo data inline. I
was thinking something like:
http://myhost.com/rest/gadgets/1234?includeGizmoDetail=true
First, is this the right way to approach this problem?
Second, if so, how can I access 'optional' query parameters like this from my
Restlet? I can make the query parameter part of the pattern given to my Router
(and access the includeGizmoDetail as a Request attribute), but then it doesn't
match when the parameter isn't present. I can attach my Restlet twice to the
Router with two patterns, but that doesn't feel right either.
Thanks,
Stokes.

Thanks Thierry, that worked fine. The word Form threw me off, but makes sense
now.
