ios - Map url parameters to objects using RESTKit

Question

is there a way to map the parameters in an URL to the results?

I got a rest service where the user can search something by its ID. The path is search/:id The results contains the name and other properties but not the ID.

I could do something like this:

NSArray *array = mappingResult.array;
for (Item *item in array) {
        [item setId:itemID];
}

but I hope there is a nicer way...

Thanks for any hints

Answer 1

You want to use the path pattern you specify in your response descriptor. Then you want to use routing (RKRoute) and metadata during your mapping. The metadata includes a routing section which gives access to the parameters extracted from the URL path.

Some info on metadata here (the docs are a little lacking).

In your mapping you want to use:

@metadata.routing.parameters.id

As the mapping source key path.

To make routing work you need to add the route to your object manager:

[manager.router.routeSet addRoute:...

And then you need to make the request in a way that means the route is used, like getObjectsAtPathForRouteNamed:object:parameters:success:failure:.
