    <p>all ...</p> <p>I've spent all weekend on this and the problem still happens. I don't know what else to do and any help would be very much appreciated. I'm trying to send JSON like this:</p> <pre><code> { "proof": { "name":"fluff", "media_type":"Photo", "description":"This is a description" }, "auth_token":"mphxNcEGJMJyU7iPmaLw" } </code></pre> <p>I keep getting the following exception from RestKit:</p> <p>2012-07-23 10:29:17.001 restkittest[8389:707] <em>*</em> Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ valueForUndefinedKey:]: this class is not key value coding-compliant for the key auth_token.'</p> <p>I suspect it's because the auth_token isn't a part of the object (proof) i'm passing, but I don't know how to pass the auth_token along with the proof since postObject only takes one object to post.</p> <p>... and this is my code to try to do it:</p> <pre><code>@implementation proof @synthesize name; @synthesize description; @synthesize media_type; @synthesize duration; @synthesize frequency_id; @end @implementation auth_token @synthesize auth_token; @end - (BOOL)createProof:(proof *)proof { BOOL ret = NO; [self.objectManager postObject:proof usingBlock:^(RKObjectLoader *loader) { loader.delegate = self; RKObjectMapping *proofMappingAccept = [RKObjectMapping mappingForClass:[proof class]]; [proofMappingAccept mapKeyPath:@"name" toAttribute:@"name"]; [proofMappingAccept mapKeyPath:@"description" toAttribute:@"description"]; [proofMappingAccept mapKeyPath:@"media_type" toAttribute:@"media_type"]; [proofMappingAccept mapKeyPath:@"duration" toAttribute:@"duration"]; RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[NSMutableDictionary class]]; [mapping mapKeyPath:@"auth_token" toAttribute:@"auth_token"]; [mapping mapKeyPath:@"proof" toRelationship:@"proof" withMapping:proofMappingAccept]; loader.serializationMapping = [mapping inverseMapping]; loader.objectMapping = mapping; }]; return ret; } </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
