TouchDB가 첨부 파일을 저장하지만 속성을 저장하지 않습니다.

Question

내 CouchModel (TSCAssetUploadDO)이 첨부 파일을 저장했지만 속성을 저장하지 못했습니다. 이 같은 문서에 발생되는

TSCAssetUploadDO *assetDO = [[TSCAssetUploadDO alloc] initWithNewDocumentInDatabase: _localAssetUploadDatabase]; 
    NSData *data = UIImageJPEGRepresentation(contact.avatar, 1.0); // may need to resize. 
    NSString *attachmentName = [docID stringByAppendingString:@".jpg"]; 
    [assetDO createAttachmentWithName:attachmentName type:@"image/jpeg" body:data]; 
    assetDO.relatedDocID = docID; 
    assetDO.docType = @"contact"; 
    RESTOperation *op2 = [assetDO save]; 
    //[op2 wait]; originally thought that making it sync may work 
    [op2 onCompletion:^{ 
     if (op2.error) NSLog(@"ERROR [TOUCHDB] %@", op2.error); 
     else 
     { 
      NSLog(@"YES! it saved"); 
     } 
     if (completionBlock) 
     { 
      completionBlock(op2.error, contact); 
     } 
     //[[NSNotificationCenter defaultCenter] postNotificationName:kNotificationDataUpdated object:nil]; 
    }]; 

(저장 한 첨부 파일,하지만 DOCTYPE 및 relatedDocID 같은 프로퍼티) 아래

{ 
"_id": "D50ED630-34ED-4A02-A9C8-204E79A0648B", 
"_rev": "1-b0ce9eaa1fb2f86dc9ae619e27ffe1ea", 
"_attachments": { 
    "QSPNGC665.jpg": { 
     "content_type": "image/jpeg", 
     "revpos": 1, 
     "digest": "md5-u9V0rgoSRN5cUW2T3xh0hw==", 
     "length": 117500, 
     "stub": true 
    } 
} 
} 

난 그냥 사용 CouchModel 없습니다.

@interface TSCAssetUploadDO: CouchModel 
    @property(nonatomic,retain) NSString *relatedDocID; 
    @property(nonatomic,retain) NSString *docType;//entity or contact 
    @property bool *toProcess; 
    @property (retain) NSDate* created_at; 
@end 

@implementation TSCAssetUploadDO 

    - (NSDictionary*) propertiesToSave { 
    // Initialize created_at the first time the document is saved: 
    if (self.created_at == nil) 
     self.created_at = [NSDate date]; 
    return [super propertiesToSave]; 
    } 
@end 

내가 잘못 했나요?

내 문제가 해결되었습니다. @dynamic을 추가해야합니다.

@implementation TSCAssetUploadDO 
    @dynamic relatedDocID, docType, toProcess, created_at; 
    <... rest of the code > 
@end
