    <p>I'm trying to map a CoreData Entity called <code>Product</code> with a web service.</p> <pre class="lang-c prettyprint-override"><code>NSString *objName = @"Product"; RKObjectManager *objectManager = [RKObjectManager managerWithBaseURL: baseUrl]; NSManagedObjectContext *context = [[MContextManager sharedContextManager] managedObjectContext]; NSManagedObjectModel *managedObjectModel = [[context persistentStoreCoordinator] managedObjectModel]; RKManagedObjectStore *managedObjectStore = [[RKManagedObjectStore alloc] initWithManagedObjectModel:managedObjectModel]; [managedObjectStore createPersistentStoreCoordinator]; [managedObjectStore createManagedObjectContexts]; objectManager.managedObjectStore = managedObjectStore; RKEntityMapping *objMap = [RKEntityMapping mappingForEntityForName:objName inManagedObjectStore:managedObjectStore]; [objMap addAttributeMappingsFromDictionary: @{ @"CODE": @"code", @"LABEL": @"label", }]; RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:objMap pathPattern:nil keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]; [objectManager addResponseDescriptor:responseDescriptor]; [objectManager getObjectsAtPath:objName parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) { NSLog(@"ok"); } failure:^(RKObjectRequestOperation *operation, NSError *error) { NSLog(@"ko"); }]; return; </code></pre> <p>You will guess <code>MContextManager</code> is my context manager, I use it for all my queries with CoreData.</p> <p>It's been several hours that I'm trying to map this simple Entity, the error I'm getting is the following:</p> <blockquote> <p>Cannot create managed object contexts: The persistent store coordinator does not have any persistent stores. This likely means that you forgot to add a persistent store or your attempt to do so failed with an error.</p> </blockquote> <p>I though I was setting the persistent store on the first lines, wasn't I ?</p> <h2>Update</h2> <p>I have added this for persistent store:</p> <pre><code>NSURL *appDocs = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject]; NSString *storeURL = [appDocs URLByAppendingPathComponent:@"my-model.sqlite"].absoluteString; [managedObjectStore addSQLitePersistentStoreAtPath:storeURL fromSeedDatabaseAtPath:nil withConfiguration:nil options:nil error:nil]; </code></pre> <p>With still the same error</p>

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.
