PORestkit mapping error
text
Body
copied!<p>I am new to restkit, and i am using it in my application along with core data. I was pretty amazed with the way restkit works with core- data. It is simply amazing. But i am facing a major issue while parsing one of my webservices. The app keeps on crashing and is not able to map a value from the response. Following is my response-</p> <p>[ { "id": 10, "created": "2012-10-06 13:32:09 +0000", "createdBy": null, "functionalCurrency": null, "imageUrl": null, "lat": null, "lon": null, "maxOccupancy": 0, "name": "Patio Dining", "posX": 0, "posY": 0, "reportingCurrency": null, "salesTaxRate1": 0, "salesTaxRate2": 0, "salesTaxRate3": 0, "salesTaxRate4": 0, "timezone": "-0830", "transactionalCurrency": null, "updated": "2012-10-06 13:32:09 +0000", "updatedBy": null}]</p> <p>I am getting the following error.- </p> <p><strong>E restkit.object_mapping:RKObjectMappingOperation.m:262 Validation failed while mapping attribute at key path 'locationId' to value 10. Error: The operation couldn’t be completed. (Cocoa error 1610.) -[__NSCFNumber length]: unrecognized selector sent to instance 0x774e020</strong></p> <p>My location class is declared as follows-</p> <pre><code>@interface Location : NSManagedObject @property (nonatomic,strong)NSNumber *locationId; @property (strong, nonatomic) NSString *created; @property (nonatomic,strong) NSString *createdBy; @property (nonatomic,strong) NSString *functionalCurrency; @property (nonatomic,strong) NSString *imageUrl; @property (strong, nonatomic) NSString *lat; @property (strong, nonatomic) NSString *lon; </code></pre> <p>I initialize the manager as follows-</p> <pre><code> RKURL *baseURL = [RKURL URLWithBaseURLString:serverUrl]; objectManager = [RKObjectManager objectManagerWithBaseURL:baseURL]; objectManager.client.baseURL = baseURL; objectManager.client.requestQueue.showsNetworkActivityIndicatorWhenBusy = YES; [RKObjectManager setSharedManager:objectManager]; [objectManager loadObjectsAtResourcePath:[NSString stringWithFormat:@"%@", [URL resourcePath]] delegate:self]; </code></pre> <p>When i try to set the locationId to NSString the RKObjectManager simply does not match any values after '9'. and when set to NSNumber it does not match any values after '2'. </p> <p>Please help me. The same thing is happening for RKManagedObjectMapping and hence no data goes into my core data file. </p>
