Map JSON response that has brackets with RESTKit - ios

Question

I'm doing a GET request with RESTKit, and I need sone help mapping the JSON response.
Here is the response that I need to map:
{"limit_hit":false,"providers":
[{"id":876553,
"name":"Cooper, Bradley N, DDS",
"specialty_groups":["Other Provider"],
"tags":[],
"has_comments":false,
"number_of_comments":0,
"locations":
[{"address":"1234 Rifle Range Road, El Cerrito, CA, 94530",
"providers_at_address_count":1,
"client_product_count":0,
"non_client_product_count":2,
"address_lines":["1234 Rifle Range Road, El Cerrito, CA, 94530"],
"address_id":234578,
"specialty_groups":
[{"specialty_group":"Other Provider"}],
"provider_types":
[{"provider_type":"Other Provider"}]},
{"address":"7501 Mission Rd, Shawnee Mission, KS, 66208",
"providers_at_address_count":2,
"client_product_count":0,
"non_client_product_count":2,
"address_lines":["7654 Main S, El Cerrito, CA, 94530"],
"address_id":654432,
"specialty_groups":
[{"specialty_group":"Other Provider"}],
"provider_types":
[{"provider_type":"Other Provider"}]
}]
}]
}
I want to be able to map both addresses, but I don't know how. All I'm able to do currently is map the id, name, has_comments, and number_of_comments (I'm using the keypath of "providers").
Here is my current mapping provider:
+ (RKMapping *)searchMapping
{
RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[ProviderSearch class]];
[mapping addAttributeMappingsFromDictionary:#{
#"id": #"doctorID",
#"name": #"name",
}];
return mapping;
}
What exactly am I doing wrong, and how do I fix it?

Answer 1

Create another method to return the mapping for locations and then associate that mapping to this original one. Like this:
// ProviderLocation.m
+ (RKObjectMapping *)objectMapping
{
RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[ProviderLocation class]];
[mapping addAttributeMappingsFromDictionary:#{
#"address": #"address",
...
}];
return mapping;
}
Relationship:
+ (RKObjectMapping *)searchMapping
{
RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[ProviderSearch class]];
[mapping addAttributeMappingsFromDictionary:#{
#"id": #"doctorID",
#"name": #"name",
}];
RKObjectMapping *locationsMapping = [ProviderLocation objectMapping];
[mapping addPropertyMapping:
[RKRelationshipMapping relationshipMappingFromKeyPath:#"locations" toKeyPath:#"locations" withMapping:locationsMapping]];
return mapping;
}
Just remember to create a NSArray property in ProviderLocation.h named locations.

i've never used RKObjectMapping before but the "locations" you have there are an array of dictionary objects. so you would need an
NSArray loc = [myJson objectForKey:#"locations"];
for(NSDictionary *dict in loc){
//here each dict obj will have your "address", "providers_at_address_count" and etc... so if you want to access any of them you can call...
NSString *addr = [dict objectForKey:#"address"];
}
now somehow convert that to what you are doing with RXObjectMapping and you are golden =P
