MagicalRecord relationship mapping duplicates objects despite primary keys

问题 I'm in need of some assistance for an issue I am experiencing with MagicalRecord data importing. I was under the impression that MagicalRecord was able to handle relationship mapping without duplicating objects by looking at the primary keys ( relatedByAttribute ). Here's a simple JSON: [ { parentId: "<unique id>", parentName : "<name>", children : [ { childId: "<unique id>", childName: "<name>" }, { childId: "<unique id>", childName: "<name>" } ] }, { <another parent with children> } ] I've

Error creating a separate NSManagedObjectContext

问题 Before getting into my issue, please have a look at this image. Here is the actual data model: I retrieve a set of Records from a web API, create objects out of them, save them in core data and display them in the Today view. By default these records are returned for the current date. The user can tap on Past button to go to a separate view where he can choose a past or future date from a date picker view and view Records for that selected date. This means I have to call the API again passing

UICollectionView with Multiple subclassed UICollectionViewCell

由 匆匆过客 提交于 2019-12-04 02:38:50
I have multiple sections in my UICollectionView grouped by "datasetType". I also have a custom UICollectionViewCell for each section. How can I determine which custom UICollectionViewCell I need in the cellForItemAtIndexPath method? My first though was go to based of the [sectionInfo name] : id sectionInfo = [[self.fetchedResultsController sections] objectAtIndex:indexPath.section]; if ([[sectionInfo name] isEqualToString:@"DatasetA"]) { DatasetACell *datasetACell = [collectionView dequeueReusableCellWithReuseIdentifier:datasetACellIdentifer forIndexPath:indexPath]; DatasetA *datasetA = [self

I just started using MagicalRecord, and this might be a stupid question, but it's really bothering me... I am using MagicalRecord with sqlite, and when I initiate MagicalRecord, I used [MagicalRecord setupCoreDataStackWithStoreNamed:@"OrderSystem.sqlite"]; and it produced the following messages: 2012-10-16 16:54:48.966 OrderSystem[4135:c07] +NSManagedObjectContext(MagicalRecord) MR_contextWithStoreCoordinator: -> Created : Context * MAIN THREAD * When I tried to store my entity with the following code using a background thread: [MagicalRecord saveInBackgroundWithBlock:^(NSManagedObjectContext

Using an existing SQLite database in MagicalRecord

由 纵饮孤独 提交于 2019-12-03 21:56:50
问题 I've created a SQLite database that contains records from some JSON using this tutorial, and I want to use MagicalRecord to query it. MagicalRecord sees the NSManagedObject ( BlogPost ) and can create records, but it doesn't see the prepopulated records, so I'm guessing it's not seeing the SQLite file I've added. I've verified that the SQLite database does indeed contain rows using a SQLite client. In application:didFinishLaunchingWithOptions: , I've put: [MagicalRecord

Using magicalrecords library in custom static framework iOS

由 ♀尐吖头ヾ 提交于 2019-12-03 17:11:05
I've been implementing a custom static framework for iOS. Everything is working well, but now I realized that I need a store information via coredata in the framework. I've been using the magicalrecord library with my previous projects and I was wondering if anyone has any experience integrating magicalrecord into your own custom static framework. When ever I call the setupcorestack method inside my framework code nothing happens. JRG-Developer Here's how we've done it: // 1: Note that all setup is done within the AppDelegate of the project (not the framework) - (BOOL)application:

How do I set up Core Data lightweight migration using MagicalRecord?

由 泪湿孤枕 提交于 2019-12-03 14:46:30
I have hit a brick wall trying to setup lightweight migration of Core Data using MagicalRecord. I have looked at all of the posts on this subject, using Google and SO. I understand how the persistentStoreCoordinator works and what the settings I am trying to make also do. Here's my code: AppDeligate.h NSPersistentStoreCoordinator *persistentStoreCoordinator; AppDelegate.m - (NSPersistentStoreCoordinator *)persistentStoreCoordinator { if (persistentStoreCoordinator != nil) { return persistentStoreCoordinator; } NSURL *storeUrl = [NSURL fileURLWithPath: [[self applicationDocumentsDirectory]
