如何将扁平对象序列化回服务器，在 RestKit 中未扁平化 [英] How to serialize a flattened object back to server, unflattened in RestKit

问题描述

使用 RestKit 0.10.1，我提供了类似于这种 json 格式的对象:

Using RestKit 0.10.1, I have objects served similar to this json format:

{"objects": [
    {"owner": 1, 
     "_id": 823, 
     "data": {
         "diam": 5.0, 
         "plant_date": "10/02/2008"}
    }, 
     ...   ] }

在客户端，我不需要子对象或关系，所以我扁平化到我的对象的属性:

on the client side, I do not need to have sub objects or relationships, so I flatten to attributes of my object:

[myMapping mapKeyPathsToAttibutes: 
    @"_id", @"id", 
    @"owner", @"owner", 
    @"data.diam", @"diam", //here is what I mean by flatten; notice data.diam -> diam
    @"data.plant_date", @"plant_date", nil];

我读取这些数据没有问题，但是当我想序列化它时，只有顶级属性会被发送到服务器.当我序列化时，这是服务器得到的:

I have no problem reading this data, but when I want to serialize it, only the top-level attributes get sent to the server. When I serialize, here is what the server gets:

{"_id":0,"owner":1}

请注意，我已正确(我认为)使用上述的 inverseMapping 注册了序列化映射:

Note that I have correctly (I think) registered the Serialization mapping with an inverseMapping of the above:

[objectManager.mappingProvider setSerializationMapping:[myMapping inverseMapping] forClass:[MyClass class]];

何时我像这样发布对象:

myObject = [MyClass object];
myObject.diam = [NSNumber numberWithInt:5];
myObject.plant_date = myDate;

[[RKObjectManager sharedManager] postObject:myObject delegate:self];

我希望拥有完整的、未扁平化的结构:

I would like to have the complete, unflattened structure:

{"_id":0,"owner":1, "data": {"diam": 5.0, "plant_date": "10/02/2008"} }

如何使用 RestKit 实现将注册对象映射到服务器的键路径(即data.diam")发布?

How can I achieve posting a keypath (i.e. "data.diam") mapping registered object to server using RestKit?

推荐答案

请注意，此错误已在 RestKit 中修复，并在 0.20 中发布.请参阅变更集@https://github.com/RestKit/RestKit/commit/66d9073d98c88c88c85c88c8c88c88c88c88c8c88c8c88c8c88c88c88c8c98c88c8c98c8c98c9f663fc998bbe738945e9bbe738945e9

Note that this bug has been fixed in RestKit on the development for release in 0.20. See the changeset @ https://github.com/RestKit/RestKit/commit/64e9c7cb6d04dd8750e9f663fc998bbe738945e9
