So I think my question here, is, what should I use when inserting a detail object to properly set the relationship to Account.
some example on how I should approach the problem would be nice, or a step-by-step :D

I do this, where I have an EventImage that refers back to a main Event, "self" is the managed object for the Event, which is your Account:



// create new EventImage, this would be akin to your AccountDetails
imageHolder = (EventImage*)
[NSEntityDescription insertNewObjectForEntityForName:@"EventImage"
inManagedObjectContext: [self managedObjectContext]];


[imageHolder setImage:image]; // set some data in the new object

	    // Add reference from Event to it's Image
            [self setValue:imageHolder forKey:@"imageHolder"];

	    // Add the reverse relationship, from the image back to the event.
            [imageHolder setValue:self forKey:@"event"];
