Question

i got into an issue with RKDynamicObjectMapping, however it could be
that i misuse it.

I have the following scenario

1. request to the service to get areas
2. choose area
3. request to the service to get journals for selected area

data returned by both calls looks like that

{ d: [{cutID:""}, {cutID:""}, {cutID:""}] } 
{ d: [{journalID:""}, {journalID:""}, {journalID:""}] } 

i have the following code

RKObjectMapping* cutMapping = [RKObjectMapping mappingForClass:[Cut 
class]]; 
[cutMapping mapKeyPath:@"CutID" toAttribute:@"cutID"]; 
RKObjectMapping* journalMapping = [RKObjectMapping mappingForClass: 
[Journal class]]; 
[journalMapping mapKeyPath:@"journalID" toAttribute:@"journalID"]; 
RKDynamicObjectMapping * dynamicMapping  = [RKDynamicObjectMapping 
dynamicMapping]; 
[dynamicMapping setObjectMapping:journalMapping 
whenValueOfKeyPath:@"__metadata.type" isEqualTo:@"JournalDetails"]; 
[dynamicMapping setObjectMapping:cutMapping 
whenValueOfKeyPath:@"__metadata.type" isEqualTo:@"Cut"]; 
[[[RKObjectManager sharedManager] mappingProvider] 
setMapping:dynamicMapping forKeyPath:@"d"]; 

.... 

[objectManager loadObjectsAtResourcePath:getResourcePath 
delegate:self]; 

.... 

and later

[objectManager loadObjectsAtResourcePath:getResourcePath 
delegate:obj]; 

results of first request, which returns Cut objects, is mapped flawlessly, but not for second which returns Journal objects.
logging in request:didLoadResponse showed that service returns
expected json , so the issue is with mappings
how to make it work with two mappings ?

Anyone using RestKit Dynamic Mapping yet ?

Answer 1

I presume you’ve checked that your Cut object is mapping to a to-many relationship in the CoreData entity?

If so can you turn on the RESTKit logging and post the results
