I just can't figure out this error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** setObjectForKey: key cannot be nil
Here is some sample JSON
[{"storeId":"22","storeName":"Jewel Osco","storeAddress1":"890 N Western Ave","storeAddress2":"","storeCity":"Lake Forest","storeState":"IL","storeZipCode":"","storeGfCount":"71","storeListCount":"2","storeDistance":"1.13","products":[{"storeId":"22","productId":"61","upcCode":"00090800000751","brandDesc":"Herb Pharm","productName":"Herb Pharm Black Elderberry Herbal Glycerite Extract"},{"storeId":"22","productId":"64","upcCode":"00698997807308","brandDesc":"Udi's","productName":"Udi's Soft N' Chewy Granola Bars Chocolate Chip - 5 CT"}]}]
It is an array of stores with a one to many array of products.
If I run my query without the relationship it runs perfectly. However when I add in the relationship it fails.
Here is the related mapping:
class func defaultMapping(objectManager:RKObjectManager!) -> RKEntityMapping{
let managedObjectStore:RKManagedObjectStore = objectManager.managedObjectStore!
let defaultMapping = RKEntityMapping(forEntityForName: "LocatorStoreProduct", inManagedObjectStore: managedObjectStore)
defaultMapping.identificationAttributes = ["productId","storeId"]
let mappingDictionary:[String:String] = [
"productId":"productId" ,
"storeId":"storeId" ,
"upcCode":"upcCode" ,
"brandDesc":"brand" ,
"productName":"productName"
]
defaultMapping.addAttributeMappingsFromDictionary(mappingDictionary)
return defaultMapping
}
Here is the assignment of the mapping:
class func defaultMapping(objectManager:RKObjectManager!) -> RKEntityMapping{
let managedObjectStore:RKManagedObjectStore = objectManager.managedObjectStore!
let defaultMapping = RKEntityMapping(forEntityForName: "LocatorStore", inManagedObjectStore: managedObjectStore)
defaultMapping.identificationAttributes = ["extId"]
let mappingDictionary:[String:String] = [
"storeId":"extId" ,
"storeName":"storeName" ,
"storeAddress1":"address1" ,
"storeAddress2":"address2" ,
"storeCity":"city" ,
"storeState":"state" ,
"storeZipCode":"zipCode" ,
"stoerGfCount":"totalCount",
"storeListCount":"inListCount",
"storeDistance":"distance"
]
defaultMapping.addAttributeMappingsFromDictionary(mappingDictionary)
//HERE IS MY RELATIONSHIP MAPPING:
let lspMapping = LocatorStoreProduct.defaultMapping(objectManager)
let relationshipMapping = RKRelationshipMapping(fromKeyPath: "products", toKeyPath: "locatorStoreProducts", withMapping: lspMapping)
defaultMapping.addPropertyMapping(relationshipMapping)
return defaultMapping
}
Been staring at this for hours and can't see what key I am missing
