Why does RestKit produce deeply recursive property mappings? - restkit

Question

I am trying to map moderately complex JSON into a nested object structure. The Shops object is recursive, but the ErrorStatus object is not. However, a debugging breakpoint taken just after the reationshipMappingFromKeyPath:#"ErrorStatus" below, shows that entityMapping -> ErrorStatus is deeply recursive through _mutablePropertyMappings. Unfortunately the debug doesnt seem to support copying, otherwise I would show it here. Any hint at what's up would be greatly appreciated.
#implementation LLSResponse
+ (RKObjectMapping *)jsonMapping
{
RKLogConfigureByName("RestKit/ObjectMapping", RKLogLevelTrace); //??? debugging
RKLogConfigureByName("RestKit/Networking", RKLogLevelTrace); //??? debugging
NSLog(#"===== LLSResponse.jsonMapping/RestKitMapping");
RKObjectMapping * entityMapping = [RKObjectMapping mappingForClass:[LLSResponse class]];
[entityMapping addPropertyMapping:
[RKRelationshipMapping relationshipMappingFromKeyPath:#"ErrorStatus"
toKeyPath:#"ErrorStatus"
withMapping:[ErrorStatus jsonMapping]]];
[entityMapping addPropertyMapping:
[RKRelationshipMapping relationshipMappingFromKeyPath:#"Shops"
toKeyPath:#"Shops"
withMapping:[Shops jsonMapping]]];
[entityMapping addPropertyMapping:
[RKRelationshipMapping relationshipMappingFromKeyPath:#"Events"
toKeyPath:#"Events"
withMapping:[Events jsonMapping]]];
return entityMapping;
}
- (NSArray *) getAllEvents
{
NSLog(#"============ getAllEvents");
Events * events = self.events;
NSArray *allEvents = events.events;
return allEvents;
}
#end
#implementation ErrorStatus
+ (RKObjectMapping *)jsonMapping
{
NSLog(#"===== ErrorStatus.jsonMapping");
RKObjectMapping * entityMapping = [RKObjectMapping mappingForClass:[ErrorStatus class]];
[entityMapping addAttributeMappingsFromDictionary:#{
#"#ID" : #"_id",
#"#Status" : #"Status",
}];
return entityMapping;
}
#end
#implementation Events
+ (RKObjectMapping *)jsonMapping
{
NSLog(#"===== Events.jsonMapping");
RKObjectMapping * entityMapping = [RKObjectMapping mappingForClass:[Events class]];
[entityMapping addPropertyMapping:
[RKRelationshipMapping relationshipMappingFromKeyPath:#"Event"
toKeyPath:#"Event"
withMapping:[EventDO jsonMapping]]];
return entityMapping;
}
#end
#implementation Shop
+ (RKObjectMapping *)jsonMapping
{
NSLog(#"===== Shop.jsonMapping");
RKObjectMapping * entityMapping = [RKObjectMapping mappingForClass:[Shop class]];
[entityMapping addAttributeMappingsFromDictionary:#{
#"#ID" : #"_id",
#"#Title" : #"title",
}];
[entityMapping addPropertyMapping:
[RKRelationshipMapping relationshipMappingFromKeyPath:#"Shop"
toKeyPath:#"Shop"
withMapping:entityMapping]];
return entityMapping;
}
#end
#implementation Shops
+ (RKObjectMapping *)jsonMapping
{
NSLog(#"===== Shops.jsonMapping");
RKObjectMapping * entityMapping = [RKObjectMapping mappingForClass:[Shops class]];
[entityMapping addPropertyMapping:
[RKRelationshipMapping relationshipMappingFromKeyPath:#"Shop"
toKeyPath:#"Shop"
withMapping:[Shop jsonMapping]]];
return entityMapping;
}
#end
I posted a more general question with more code and the JSON in question, but this may capture the essence of the problem. See RestKit not mapping recursive JSON to objects
