    text
    copied!<p>I've tried the proposed solutions for similar questions on SO but with no luck. The fetch request can't locate the entity name 'GarmentType'.</p> <p>Here is my data model: <img src="https://i.stack.imgur.com/vdiwQ.jpg" alt="enter image description here"></p> <p>The error is thrown at the executeFetchRequest in this helper category:</p> <pre><code>// // GarmentType+Create.m // Dressy // // Created by Michael Mangold on 9/4/13. // Copyright (c) 2013 Michael Mangold. All rights reserved. // #import "GarmentType+Create.h" @implementation GarmentType (Create) // Creates or fetches a Core Data GarmentType entity. + (GarmentType *)garmentTypeWithName:(NSString *)name inManagedObjectContext:(NSManagedObjectContext *)context { NSLog(@"name:%@ context:%@",name,context); GarmentType *garmentType = nil; // Build fetch request. NSFetchRequest *request = [NSFetchRequest fetchRequestWithEntityName:@"GarmentType"]; request.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"name" ascending:YES]]; request.predicate = [NSPredicate predicateWithFormat:@"name = %@",name]; // Execute fetch requesst. NSError *error = nil; NSArray *matches = [context executeFetchRequest:request error:&amp;error]; // This is where it dies. if (!matches || [matches count] &gt; 1) { NSLog(@"Error creating GarmentType."); } else if ([matches count] == 0) { garmentType = [NSEntityDescription insertNewObjectForEntityForName:@"GarmentType" inManagedObjectContext:context]; garmentType.name = name; } else { garmentType = [matches lastObject]; } return garmentType; } @end </code></pre> <p>The name logs the correct name and the context is non nil.</p> <p>The helper is called from a UITableViewController IBAction when the 'done' button is pressed:</p> <pre><code>- (IBAction)handleDoneButton:(UIBarButtonItem *)sender { // Add garment type to core data. [DressyHelper openDocumentUsingBlock:^(UIManagedDocument *document){ GarmentType *newGarment = [GarmentType garmentTypeWithName:self.garmentTypeNameTextField.text inManagedObjectContext:document.managedObjectContext]; NSLog(@"newGarment.name:%@",newGarment.name); }]; [self dismissViewControllerAnimated:YES completion:nil]; } </code></pre> <p>newGarment.name logs fine.</p> <p>Here is the .h for GarmentType:</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; #import &lt;CoreData/CoreData.h&gt; @class Garment; @interface GarmentType : NSManagedObject @property (nonatomic, retain) NSString * name; @property (nonatomic, retain) NSSet *garments; @end @interface GarmentType (CoreDataGeneratedAccessors) - (void)addGarmentsObject:(Garment *)value; - (void)removeGarmentsObject:(Garment *)value; - (void)addGarments:(NSSet *)values; - (void)removeGarments:(NSSet *)values; @end </code></pre> <p>Apologies for the code dump but I've been struggling with this for a while. Changing the entity name results in the same error, just with the new name as the entity not found.</p> <p>Inspector for GarmentType: <img src="https://i.stack.imgur.com/aXZsu.jpg" alt="enter image description here"></p> <p>And the exception:</p> <pre><code>2013-12-10 13:51:50.320 Dressy[4336:70b] name:asdf context:&lt;NSManagedObjectContext: 0x8ad86f0&gt; 2013-12-10 13:51:50.323 Dressy[4336:70b] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'NSFetchRequest could not locate an NSEntityDescription for entity name 'GarmentType'' *** First throw call stack: ( 0 CoreFoundation 0x017465e4 __exceptionPreprocess + 180 1 libobjc.A.dylib 0x014c98b6 objc_exception_throw + 44 2 CoreData 0x019b4b6e -[NSFetchRequest(_NSInternalMethods) _resolveEntityWithContext:] + 510 3 CoreData 0x019b34d6 -[NSManagedObjectContext executeFetchRequest:error:] + 70 4 Dressy 0x000051de +[GarmentType(Create) garmentTypeWithName:inManagedObjectContext:] + 510 5 Dressy 0x00002170 __54-[GarmentTypeAddTableViewController handleDoneButton:]_block_invoke + 208 6 Dressy 0x00006d51 __39+[DressyHelper openDocumentUsingBlock:]_block_invoke21 + 97 7 UIKit 0x00781f7b __59-[UIDocument saveToURL:forSaveOperation:completionHandler:]_block_invoke570 + 54 8 libdispatch.dylib 0x01e43440 _dispatch_barrier_sync_f_slow_invoke + 71 9 libdispatch.dylib 0x01e544b0 _dispatch_client_callout + 14 10 libdispatch.dylib 0x01e4275e _dispatch_main_queue_callback_4CF + 340 11 CoreFoundation 0x017aba5e __CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE__ + 14 12 CoreFoundation 0x016ec6bb __CFRunLoopRun + 1963 13 CoreFoundation 0x016ebac3 CFRunLoopRunSpecific + 467 14 CoreFoundation 0x016eb8db CFRunLoopRunInMode + 123 15 GraphicsServices 0x03a4d9e2 GSEventRunModal + 192 16 GraphicsServices 0x03a4d809 GSEventRun + 104 17 UIKit 0x00237d3b UIApplicationMain + 1225 18 Dressy 0x0000585d main + 141 19 libdyld.dylib 0x020e670d start + 1 ) libc++abi.dylib: terminating with uncaught exception of type NSException (lldb) </code></pre> <p>TIA</p>
