Restkit Post Nicht senden Objekt

Ich bin erstellen einer IOS-app, die verwendet restkit und ich bin in der Lage zu tun, um Anfragen kein problem und es Karten richtig und alles, aber ich habe Probleme damit, restkit, um einen BEITRAG an die Datenbank. Es wird immer eine Antwort, die sagt:

`{"errors":{"email":["can't be blank"],"password":["can't be blank"]}}`

Habe ich das Gefühl, dass das Objekt gerade nicht gesendet wird. Hier ist mein code, um alle mappings, die in meinem app-delegate.

RKObjectMapping *userMapping     = [RKObjectMapping mappingForClass:[User       class]];
RKObjectMapping *dogMapping      = [RKObjectMapping mappingForClass:[Dog        class]];
RKObjectMapping *posttimeMapping = [RKObjectMapping mappingForClass:[PostTime   class]];
RKObjectMapping *postMapping     = [RKObjectMapping mappingForClass:[Post       class]];
RKObjectMapping *activityMapping = [RKObjectMapping mappingForClass:[Activity   class]];

        //set up which attributes go where
[userMapping        addAttributeMappingsFromDictionary:[User propertyMappings]];
[dogMapping         addAttributeMappingsFromDictionary:[Dog propertyMappings]];
[posttimeMapping    addAttributeMappingsFromDictionary:[PostTime propertyMappings]];
[postMapping        addAttributeMappingsFromDictionary:[Post propertyMappings]];
[activityMapping    addAttributeMappingsFromDictionary:[Activity propertyMappings]];

        //set up relationships
[userMapping        addRelationshipMappingWithSourceKeyPath:@"dogs"         mapping:dogMapping];
[dogMapping         addRelationshipMappingWithSourceKeyPath:@"timeline"     mapping:posttimeMapping];
[posttimeMapping    addRelationshipMappingWithSourceKeyPath:@"posts"        mapping:postMapping];
[postMapping        addRelationshipMappingWithSourceKeyPath:@"activities"   mapping:activityMapping];


    //what to print
RKLogConfigureByName("RestKit/Network", RKLogLevelTrace);
RKLogConfigureByName("Restkit/Network", RKLogLevelDebug);



    //set up paths
RKObjectManager *manager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:@"http://localhost:3000"]];

NSIndexSet *statusCodes = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful); //Anything in 2x
RKResponseDescriptor *userDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:userMapping pathPattern: @"/users/1.json" keyPath:@"" statusCodes:statusCodes];
RKResponseDescriptor *signupDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:userMapping pathPattern:@"/users.json" keyPath:@"" statusCodes:statusCodes];
[manager addResponseDescriptorsFromArray:@[ userDescriptor, signupDescriptor ]];
[RKObjectManager setSharedManager:manager];

und hier ist mein post-Anforderung:

- (void) post{
RKObjectManager *manager = [RKObjectManager sharedManager];
[manager postObject:self path:@"/users.json" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
    NSLog(@"successful post");
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    NSLog(@"failed post %@", error);
    NSLog(@"%@",operation.description);
    NSLog(@"%@",operation.HTTPRequestOperation.description);
}];

}

Hier sind die logs, die ich immer bin:

Irgendein Beispiel, oder zeigen Sie in die richtige Richtung wäre toll. Habe ich fest auf dieser für eine Weile.

Wenn Sie weitere Informationen benötigen, lasst es mich einfach wissen.

Update

Ich war in der Lage, es zu arbeiten, aber nicht der richtige Weg.Grundsätzlich habe ich nur senden Sie alle Informationen, die durch die params so gerne.

- (void) post{
RKObjectManager *manager = [RKObjectManager sharedManager];
[manager postObject:self path:@"/users.json" parameters:@{@"user[email]" : self.email, @"user[password]" : self.password}  success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
    NSLog(@"Successful Post!");
    [User setCurrentUser:self];
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:[error description] delegate:nil cancelButtonTitle:@"Okay!" otherButtonTitles: nil];
    [alert show];
}];

}

Jemand irgendwelche Ideen auf, wie es zu tun richtig?

Update für Vishal
Für die Verwendung von coredata müssen Sie zum erstellen eines Verwalteten Objekt Speichern, wie dies...

 RKObjectManager *manager = [RKObjectManager managerWithBaseURL:    [NSURL URLWithString:@"http://my_url.com"]];
NSURL *modelURL = [[NSBundle mainBundle] URLForResource:@"MyDataModel" withExtension:@"momd"];
NSManagedObjectModel *managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL];
RKManagedObjectStore *managedObjectStore = [[RKManagedObjectStore alloc] initWithManagedObjectModel:managedObjectModel];
manager.managedObjectStore = managedObjectStore;

Dann sind Sie gehen zu müssen, verwenden RKEntityMapping statt RKObjectMapping

Hoffe, das hilft.

Update 2 für Vishal

[managedObjectStore createPersistentStoreCoordinator];
NSError *error;

BOOL success = RKEnsureDirectoryExistsAtPath(RKApplicationDataDirectory(), &error);
if (! success) {
    RKLogError(@"Failed to create Application Data Directory at path '%@': %@", RKApplicationDataDirectory(), error);
}
NSString *path = [RKApplicationDataDirectory() stringByAppendingPathComponent:@"Store.sqlite"];
NSPersistentStore *persistentStore = [managedObjectStore addSQLitePersistentStoreAtPath:path fromSeedDatabaseAtPath:nil withConfiguration:nil options:nil error:&error];
if (! persistentStore) {
    RKLogError(@"Failed adding persistent store at path '%@': %@", path, error);
}

[managedObjectStore createManagedObjectContexts];
managedObjectStore.managedObjectCache = [[RKInMemoryManagedObjectCache alloc] initWithManagedObjectContext:managedObjectStore.persistentStoreManagedObjectContext];
