Re: Restkit offline core data save, can't retrieve

[Matt]

You can all ignore this...it was a case of Hurp-a-Durp-itz.  My friggin fetch query was wrong because I didn't default a column to a value so it didn't pick up the new values in the DB.

Ok so I have an application that uses core data to save while in offline mode.  I can successfully push the data down to the database, however it seems that when I go to execute a fetch, none of the new data is there.

Is this some kind of caching issue?

Here is my restkit initialization methods

- (void) initializeRestKit

{

   // Retrieve the base server URL

   NSString* serverName = [[Resource_Service sharedModel] getDictValue:@"ServerName"];

   

    // RKObjectManager is our base class for any requests that involove mapping to core data

    self.RestKitObjectManager = [[RKObjectManager sharedManager] init];

    self.RestKitObjectManager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:serverName]];

   

    // Enable automatic network activity indicator management

    [AFNetworkActivityIndicatorManager sharedManager].enabled = YES;

   

    // Configure MIME Types

    self.RestKitObjectManager.requestSerializationMIMEType = RKMIMETypeJSON;

   

    // Configure the core data

    [self configureCoreData];

   

    // Add the routing paths

    [self addRoutingPaths];

   

    // Wire up any observers for the data

    [self wireUpObservers];

}

- (void) configureCoreData

{

    // Retrieve the model name

    NSString* momdName = [[Resource_Service sharedModel] getDictValue:@"ManagedObjectModelName"];

 

    // Retrieve the base SQL file Name

    NSString* sqlFileName = [RKApplicationDataDirectory() stringByAppendingPathComponent:[[Resource_Service sharedModel] getDictValue:@"DataStoreFileName"]];

   

    // Retrieve the model URL

    NSURL *modelURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:momdName ofType:@"momd"]];

   

    self.RestKitManagedObjectModel = [[[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL] mutableCopy];

    self.RestKitObjectStore = nil;

    self.RestKitObjectStore = [[RKManagedObjectStore alloc] initWithManagedObjectModel:self.RestKitManagedObjectModel];

    [self.RestKitObjectStore addSQLitePersistentStoreAtPath:sqlFileName fromSeedDatabaseAtPath:nil withConfiguration:nil options:nil error:nil];    

   

    // Create the managed object contexts

    [self.RestKitObjectStore createManagedObjectContexts];

    self.RestKitObjectManager.managedObjectStore = self.RestKitObjectStore;

   

    // Configure a managed object cache to ensure we do not create duplicate objects

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