Post-processing? about groot HOT 3 CLOSED

I had to handle with this issue in some of my apps. This is the way I solved it.

First, I created a NSManagedObject category with two methods:

+ (instancetype) grt_mergeObjectFromJSONDictionary:(NSDictionary *) dictionary
                            inManagedObjectContext:(NSManagedObjectContext *)context
                                             error:(NSError **) error;
+ (NSArray *) grt_mergeObjectsFromJSONArray:(NSArray *)array
                     inManagedObjectContext:(NSManagedObjectContext *)context
                                      error:(NSError *__autoreleasing *)error;

In its implementation, I call the Groot methods.

When I want to parse a JSON, I use always this category instead of the Groot methods. If one of my entities needs a post-processing, I just override this methods and perform the post-process there.

If you like this idea, I can provide the full code of the category.

Interesting. Those merge function are from an older version of Groot, right? I'm using GRTJSONSerialization.objectsWithEntityName to fire off a big chain of serializations which ultimately calls grt_serializeJSONDictionary for each managed object. I need to look into having my subclasses of NSManagedObject override grt_serializeJSONDictionary. I'm using Swift.

I would have thought that use case is covered by returning the serialized managed objects.
I will consider having methods that take a block for post-processing if that's not enough. Any other ideas are welcome.
